California Current map

The California Current Ecosystem (CCE) is a dynamic environment in the eastern North Pacific Ocean. Spanning nearly 3,000 km from southern British Columbia, Canada to Baja California, Mexico, the California Current encompasses the United States Exclusive Economic Zone, the coastal land-sea interface, and adjacent terrestrial watersheds along the West Coast. This highly productive coastal ecosystem is fueled by the seasonal upwelling of cold, nutrient-rich water. These seasonal episodes of productivity support populations of krill, squid, sardines, and other species that are fed upon by larger fishes, seabirds and marine mammals. Broad-scale climate forcing related to El Niño / La Niña events and the Pacific Decadal Oscillation help determine how much upwelling will occur at points along the coast in a given year. These waters support some of the most productive fisheries in the world. Millions of dollars are paid directly to fishermen from commercial fishery landings, and over 100,000 jobs on and off the water are supported by the coast's seafood industry. Fisheries are an important part of California Current's economy, culture, and history and provide a wide variety of sustainable and local seafood.

Understanding the Time series plots

Time series plots show the changes in each indicator as a function of time, over the period 1980-present. Each plot also shows horizontal lines that indicate the median (middle) value of that indicator, as well as the 10th and 90th percentiles, each calculated for the entire period of measurement. Time series plots were only developed for datasets with at least 10 years of data. Two symbols located to the right of each plot describe how recent values of an indicator compare against the overall series. A black circle indicates whether the indicator values over the last five years are on average above the series 90th percentile (plus sign), below the 10th percentile (minus sign), or between those two values (solid circle). Beneath that an arrow reflects the trend of the indicator over the last five years; an increase or decrease greater than one standard deviation is reflected in upward or downward arrows respectively, while a change of less than one standard deviation is recorded by a left-right arrow.

Pacific Decadal Oscillation (PDO)

During the last five years, the PDO indicator has trended downward, shifting from positive phase to negative phase in 2019.

graph of Pacific Decadal Oscillation 1980-2020

Values correspond to Index scores

Description of time series:

Positive PDO values typically mean cool surface water conditions in the interior of the North Pacific Ocean and warm surface waters along the North American Pacific Coast while negative PDO conditions typically mean warm surface water conditions in the interior to the North Pacific Ocean and cool surface waters along the North American Pacific Coast. During the last five years, the PDO indicator has trended downward, shifting from positive phase to negative phase in 2019.

 

Description of Pacific Decadal Oscillation (PDO):

The Pacific Decadal Oscillation (PDO) is a long-term pattern of Pacific climate variability that comprises multiple physical forcing mechanisms. The extreme phases of this climatic condition are classified as warm or cool, based on deviations from average ocean temperature in the northeast and central North Pacific Ocean. When the PDO has a positive value, sea surface temperatures are below average (cool) in the interior North Pacific and warm along the Pacific Coast. When the PDO has a negative value, the climate patterns are reversed, with above average sea surface temperatures in the interior and sea surface temperatures below average along the North American coast. On shorter timescales a positive (negative) PDO is often related to El Niño (La Niña). The PDO waxes and wanes on longer timescales as well; warm and cold phases may persist for decades. Major changes in northeast Pacific marine ecosystems have been correlated with phase changes in the PDO. Warm phases have seen enhanced coastal ocean biological productivity in Alaska and inhibited productivity off the west coast of the United States, while cold PDO phases have seen the opposite, north-south pattern of marine ecosystem productivity. We present data from the Pacific Islands, Alaska, and California Current regions

 

Data Background:

Climate indicator data was accessed from the NOAA NCEI (https://www.NCEI.noaa.gov/teleconnections/pdo/data.csv). The data plotted are unitless and based on Sea Surface Temperature anomalies averaged across a given region.

El Niño-Southern Oscillation (Oceanic Niño Index)

The ONI shifted  from La Nina conditions to neutral conditions in early 2023, and with continued sea-surface warming now indicate that an El Nino has begun. 

graph of Oceanic Nino anomaly index 1980-2020

Values correspond to Index scores

Description of time series:

The Oceanic Niño Index (ONI) is NOAA’s primary index for monitoring the El Niño-Southern Oscillation climate pattern. It is based on Sea Surface Temperature values in a particular part of the central equatorial Pacific, which scientists refer to as the Niño 3.4 region. Positive values of this indicator, greater than +0.5, indicate warm El Niño conditions, while negative values, less than -0.5, indicate cold La Niña conditions. Values between +0.5 and -0.5 are considered ENSO neutral. The ONI shifted  from La Nina conditions to neutral conditions in early 2023, and with continued sea-surface warming now indicate that an El Nino has begun. 

 

Description of El Niño-Southern Oscillation (ENSO):

El Niño and La Niña are opposite phases of the El Niño-Southern Oscillation (ENSO), a cyclical condition occurring across the Equatorial Pacific Ocean with worldwide effects on weather and climate. During an El Niño, surface waters in the central and eastern equatorial Pacific become warmer than average and the trade winds - blowing from east to west - greatly weaken. During a La Niña, surface waters in the central and eastern equatorial Pacific become much cooler, and the trade winds become much stronger. El Niños and La Niñas generally last about 6 months but can extend up to  2 years. The time between events is irregular, but generally varies between 2-7 years. To monitor ENSO conditions, NOAA operates a network of buoys, which measure temperature, currents, and winds in the equatorial Pacific. 

 

This climate pattern impacts people and ecosystems around the world by affecting large scale areas of tropical convection, and by extension, the jet streams. Interactions between the ocean and atmosphere alter weather globally and can result in severe storms or mild weather, drought or flooding. Beyond “just” influencing the weather and ocean conditions, these changes can produce secondary results that influence food supplies and prices, forest fires and flooding, and create additional economic and political consequences. For example, along the west coast of the U.S., warm El Niño events are known to inhibit the delivery of nutrients from subsurface waters, suppressing local fisheries. El Niño events are typically associated with fewer hurricanes in the Atlantic while La Niña events typically result in greater numbers of Atlantic hurricanes.

 

Data Background:

ENSO ONI data was accessed from NOAA’s Climate Prediction Center (https://origin.cpc.ncep.noaa.gov/products/analysis_monitoring/ensostuff/ONI_v5.php). The data are plotted in degrees Celsius and represent Sea Surface Temperature anomalies averaged across the so-called Niño 3.4 region in the east-central tropical Pacific between 120°-170°W and 5°S-5°N .

Sea Surface Temperature

During the last five years there has been a significant downward trend and values have remained within the 10th and 90th percentiles.

California Current sea surface temperature

Sea surface temperature is defined as the average temperature of the top few millimeters of the ocean. Sea surface temperature monitoring tells us how the ocean and atmosphere interact, as well as providing fundamental data on the global climate system

Data background and limitations:

The NOAA Coral Reef Watch (CRW) daily global 5km Sea Surface Temperature (SST) product, also known as CoralTemp, shows the nighttime ocean temperature measured at the surface. The CoralTemp SST data product was developed from two, related reanalysis (reprocessed) SST products and a near real-time SST product. Monthly composites were used for this analysis.

Sea Level

During the last five years, there has been no trend and values are between the 10th and 90th percentiles of all data.

graph of coastal sea level for Northeast US from 1980-2020

Sea level varies due to the force of gravity, the Earth’s rotation and irregular features on the ocean floor. Other forces affecting sea levels include temperature, wind, ocean currents, tides, and other similar processes.

 

Description of time series:

The time series shows the relative sea level for this region. During the last five years, there has been no trend and values are between the 10th and 90th percentiles of all data.

 

Indicator and source information:

NOAA monitors sea levels using tide stations and satellite laser altimeters. Tide stations around the globe tell us what is happening at local levels, while satellite measurements provide us with the average height of the entire ocean. Taken together, data from these sources are fed into models that tell us how our ocean sea levels are changing over time. For this site, data from tide stations around the US were combined to create regionally averaged records of sea-level change since 1980. We present data for all regions.

 

Data background and limitations:

Sea level data presented here are measurements of relative sea level, water height as compared to nearby land level, from NOAA tide gauges that have >20 years of hourly data served through NOAA’s Center for Operational Oceanographic Products and Services (CO-OPS) Tides and Currents website. These local measurements are regionally averaged by taking the median value of all the qualifying stations within a region. The measurements are in meters and are relative to the year 2000.

Heatwave Intensity

During the last five years there has been no trend and the five-year average is between the 10th and 90th percentiles of all observed data in the time series.

CaliCurrent intensity

Values indicate cumulative annual heatwave intensity and duration in a region in degree-days

Description of Time Series: This time series shows the average integrated degree day value for the California Current region. During the last five years there has been no trend and the five-year average is between the 10th and 90th percentiles of all observed data in the time series.

Indicator Source Information:

The marine heatwave data shown here are calculated by NOAA’s National Centers for Environmental Information using Optimum Interpolation Sea Surface Temperature (OISST) data. The NOAA 1/4° OISST is a long term Climate Data Record that incorporates observations from different platforms (satellites, ships, buoys and Argo floats) into a regular global grid. The dataset is interpolated to fill gaps on the grid and create a spatially complete map of sea surface temperature. Satellite and ship observations are referenced to buoys to compensate for platform differences and sensor biases.

 

Data Background and Caveats:

Heatwave metrics are calculated using OISST, a product that uses some forms of interpolation to fill data gaps. Heatwaves are defined by Hobday et al., 2016 as distinct events where SST anomaly reaches the 90th percentile in a pixel for at least 5 days, separated out by 3 or more days.

Chlorophyll-a

During the last five years there has been a significant upward trend while values have remained within the 10th and 90th percentiles of all observed data in the time series.

Chlorophyll-A time series for California Current

Chlorophyll a, a pigment produced by phytoplankton, can be measured to determine the amount of phytoplankton present in water bodies. From a human perspective, high values of chlorophyll a can be good (abundance of nutritious diatoms as food for fish) or bad (Harmful Algal Blooms that may cause respiratory distress for people), based on the associated phytoplankton species.

 

Data Interpretation:

Time series: This time series shows the average concentration levels of chlorophyll a for the  California Current region. During the last five years there has been a significant upward trend while values have remained within the 10th and 90th percentiles of all observed data in the time series.

 

Indicator and source information:

Chlorophyll-a concentration values for this indicator were obtained using data from the European Spatial Agency (ESA) that is a validated, error-characterized, Essential Climate Variable (ECV) and climate data record (CDR) from satellite observations specifically developed for climate studies. The dataset (v56.0) is created by bandshifting the reflectances values from SeaWiFS, MODIS and VIIRS to MERIS wavebands if necessary, and SeaWiFS and MODIS were corrected for inter-sensor bias when compared with MERIS in the 2003-2007 period. VIIRS and OLCI were also corrected to MERIS levels, via a two-stage process comparing against the MODIS-corrected-to-MERIS-levels (2012-2013 for VIIRS and 2016-2019 for OLCI).

Annual means for each LME were calculated from the average of the 12 monthly means in that year on a pixel by pixel basis. Then for each year, the median average was taken spatially to yield one value per year per LME.  The overall “National Annual Mean” mean was calculated as the average of all LME annual means. See the Data Background section for more details.  

 

Data background and limitations:

Satellite chlorophyll a data was extracted for each LME from the ESA OC-CCI v6.0 product. These 4 km mapped, monthly composited data were - averaged over each year to produce pixel by pixel annual composites, then the spatial median was calculated  for each LME, resulting in one value per year per LME.   This technique was used for each LME from North America and Hawaii.  The overall “National Annual Mean” was calculated as the average of all the LME annual means. Phytoplankton concentrations are highly variable (spatially and temporally), largely driven by changing oceanographic conditions and seasonal variability.

 

Zooplankton

Between 2016 and 2021 the average concentration of zooplankton biomass showed no significant trend and was similar to historical values.

Zooplankton time series California Current

Description of time series:

Between 2016 and 2021 the average concentration of zooplankton biomass showed no significant trend and was similar to historical values.

 

Indicator information

Zooplankton data for each region were obtained from the NOAA Fisheries Coastal & Oceanic Plankton Ecology, Production, & Observations Database, an integrated data set of quality-controlled, globally distributed plankton biomass and abundance data with common biomass units and served in a common electronic format with supporting documentation and access software. California Current specific data comes from the California Cooperative Oceanic Fisheries Investigations (CalCOFI) program: https://calcofi.org/

 

Data Background and Caveats:

Unlike previous years, all value are now standardized to "ml/m3". For example, EcoMon data units went from "ml/100m3" to just "ml/m3", but that did not affect the shape of the trends as it is a linear multiplicative factor. CalCOFI, however, went from "ml/m2" to "ml/m3", and the trend has changed noticeably.  It is now noisier and no clear trend.  One converts "ml/m2" to "ml/m3" by dividing by the towing depth (m).  That is a non-linear muplicative factor, so it can affect each data point and change the data shape.

Finally, a log10 value frequency histogram of the raw data values showed that 99.9% of the DV  data values were less than 15 ml/m3.   To reduce the impact of large outliers (i.e., due to a large jellyfish or an algal mat caught in the net), any DV value greater than 15 was capped at a value of just 15. Again, this would only affect < 0.1% of the data.  In some extreme cases, original DV values were over 100+ ... which greatly skewed the means and trends if not removed. This is actually standard practice.   CalCOFI offers both a "large" and "small" DV value (with the latter having large values removed), for example, and some programs automatically remove any plankter larger than the 5 cm length from the net sample before measuring the DV.

Overfished Stocks

The series shows the number of fish populations that have been listed as overfished since 2000. Between 2018 and 2023 the number of overfished stocks shows no trend.

Overfished stocks time series for California Current

The x-axis represents years. The y-axis represents the number of fish stocks or fish populations that are deemed by NOAA as overfished. Overfished means the population of fish is too low. Therefore the population cannot support a large amount of fishing.

 

Description of time series:

The series shows the number of fish populations that have been listed as overfished since 2000. Between 2018 and 2023 the number of overfished stocks shows no trend.

 

Description of Overfished stocks:

An overfished stock is a population of fish that is too low. A stock that is experiencing overfishing has an annual rate of catch that is too high. Therefore the population cannot support that level of fishing and is below that level is deemed “overfished.” A fish population can be “overfished” as the result of many factors, including overfishing, as well as habitat degradation, pollution, climate change, and disease. The Magnuson-Stevens Act mandates that overfished stocks and stocks experiencing overfishing be reported annually.   Stock status is determined by NOAA, based on the results of stock assessments.

 

Data Source:

Data were obtained from the NOAA Fisheries Fishery Stock Status website. Stocks that met the criteria for overfished status were summed by year for each region.

Endangered Species Act Threatened or Endangered Marine Mammals

Gauge and Trend Analyses were not appropriate for marine mammal data.

Number of threatened/endangered marine mammal stock from 1980-2019

Values Correspond to the Number of ESA Threatened or Endangered Species in a given region

Data Interpretation

Gauge and Trend Analyses were not appropriate for marine mammal data.

 

Description of Threatened and Endangered Marine Mammals (ESA):

NOAA Fisheries is responsible for the protection, conservation, and recovery of endangered and threatened marine and anadromous species under the Endangered Species Act (ESA). The ESA aims to conserve these species and the ecosystems they depend on. Under the ESA, a species is considered endangered if it is in danger of extinction throughout all or a significant portion of its range, or threatened if it is likely to become endangered in the foreseeable future throughout all or a significant portion of its range See a species directory of all the threatened and endangered marine species under NOAA Fisheries jurisdiction, including marine mammals. 

Under the ESA, a species must be listed if it is threatened or endangered because of any of the following 5 factors:

1) Present or threatened destruction, modification, or curtailment of its habitat or range;

2) Over-utilization of the species for commercial, recreational, scientific, or educational purposes;

3) Disease or predation;

4) Inadequacy of existing regulatory mechanisms; and

5) Other natural or manmade factors affecting its continued existence.

The ESA requires that listing determinations be based solely on the best scientific and commercial information available; economic impacts are not considered in making species listing determinations and are prohibited under the ESA. There are two ways by which a species may come to be listed (or delisted) under the ESA:

- NOAA Fisheries receives a petition from a person or organization requesting that NOAA lists a species as threatened or endangered, reclassify a species, or delist a species.

- NOAA Fisheries voluntarily chooses to examine the status of a species by initiating a status review of a species.

 

Data Background and Caveats

NOAA Fisheries goes through required regulatory steps to list, reclassify, or delist a species under the ESA. For more information, see a step-by-step description of the ESA listing process. The listing process requires time and resources; as a result, the timing and number of listed marine species is not necessarily indicative of the actual number of currently endangered or threatened species and the exact timing of when these species became eligible to be listed under the ESA. Many marine species were initially listed when the ESA was passed in 1973; others have taken more time to be listed, and some have been reclassified or delisted since then.

Marine Mammal Protection Act Strategic/Depleted Marine Mammal Stocks

Gauge and Trend Analyses were not appropriate for marine mammal data.

Strategic/depleted marine mammals time series for California Current

Values correspond to the number of MMPA Strategic or Depleted Marine Mammal Species listed each year in each region

 

Data Interpretation

Gauge and Trend Analyses were not appropriate for marine mammal data.

 

Description of Marine Mammal Strategic and Depleted Stocks (MMPA):

A stock is defined by the Marine Mammal Protection Act (MMPA), as a group of marine mammals of the same species or smaller taxa in a common spatial arrangement, that interbreed when mature. See a list of the marine mammal stocks NOAA protects under the MMPA.

 

A strategic stock is defined by the MMPA as a marine mammal stock—

- For which the level of direct human-caused mortality exceeds the potential biological removal level or PBR (defined by the MMPA as the maximum number of animals, not including natural mortalities, that may be removed from a marine mammal stock while allowing that stock to reach or maintain its optimum sustainable population); 

- Which, based on the best available scientific information, is declining and is likely to be listed as a threatened species under the Endangered Species Act (ESA) within the foreseeable future; or 

- Which is listed as a threatened or endangered species under the ESA, or is designated as depleted under the MMPA. 

 

A depleted stock is defined by the MMPA as any case in which—

- The Secretary of Commerce, after consultation with the Marine Mammal Commission and the Committee of Scientific Advisors on Marine Mammals established under MMPA title II, determines that a species or population stock is below its optimum sustainable population; 

- A State, to which authority for the conservation and management of a species or population stock is transferred under section 109, determines that such species or stock is below its optimum sustainable population; or 

- A species or population stock is listed as an endangered species or a threatened species under the ESA. 

 

Data Background and Caveats

NOAA Fisheries prepares marine mammal stock assessment reports to track the status of marine mammal stocks. Some marine mammal stocks are thriving, while others are declining, and we often don’t know all the reasons behind a species or stock’s population trend. Because of this variability, it is difficult to indicate the state of an ecosystem or specific region using stock assessment data for marine mammal species that often range across multiple ecosystems and regions.

Marine Species Distribution - Latitude

Between 2017 and 2022 the average species latitudinal shift showed an increasing trend, indicating a northward shift in distributions.

Calicurrent Latitude

Values indicate annual cumulative change in centroid across all species in a region in degrees N

 

Description of Time Series: Between 2017 and 2022 the average species latitudinal shift showed an increasing trend, indicating a northward shift in distributions.

 

Indicator Source Information:

This data was obtained from the Distribution Mapping and Analysis Portal (DisMAP). provides important information for fisheries management including which species are caught where and at what depth.The latitudinal (or depth) centroid is the biomass-weighted center of a population’s distribution. This metric is calculated by the DisMAP portal team using the interpolated biomass distribution surface they generated from the survey catch data, such that the latitudinal (or depth) centroids are the mean latitude (or depth) of the species distribution, where each raster cell latitude (or depth) is weighted by the value of weight-per-unit-effort for that cell. Scientists at NOAA use this data to calculate each species’ centroid as the mean latitude and depth of catch in the survey, weighted by biomass. The centroid for each species is calculated for each year after standardizing the data to ensure that the measure is consistent over time despite changes in survey techniques and total area surveyed. This data provides important information for fisheries management including which species are caught where and at what depth.

 

Data Background and Caveats:

The regional and national marine species distributions shown here represent the average shift in the centroid of a selected core set of species that are caught every year in surveys conducted in each region. These species represent a wide range of habitats and species types. As species distributions respond to many environmental and biological factors, combining data from multiple diverse species allows for a more complete picture of the general trends in marine species distribution. In order to more easily track and display changes in these distributions, the first year is standardized to zero. Thus, the indicator represents relative change in distribution from the first survey year. 

Marine Species Distribution - Depth

Between 2017 and 2022 the average species water column depth shift shows a significant downward trend, indicating the distribution moved deeper.

CalCurrent Depth

Values Indicate annual cumulative change in average species centroid depth in meters - for example, a value of -5 indicates the species centroid moving deeper by 5m.

 

Description of Time Series: Between 2017 and 2022 the average species water column depth shift shows a significant downward trend, indicating the distribution moved deeper.

This data was obtained from the Distribution Mapping and Analysis Portal (DisMAP). The latitudinal (or depth) centroid is the biomass-weighted center of a population’s distribution. This metric is calculated by the DisMAP portal team using the interpolated biomass distribution surface they generated from the survey catch data, such that the latitudinal (or depth) centroids are the mean latitude (or depth) of the species distribution, where each raster cell latitude (or depth) is weighted by the value of weight-per-unit-effort for that cell. The centroid for each species is calculated for each year after standardizing the data to ensure that the measure is consistent over time despite changes in survey techniques and total area surveyed. This data provides important information for fisheries management including which species are caught where and at what depth.

 

Data Background and Caveats:

The regional and national marine species distributions shown here represent the average centroid of a selected core set of species that are caught every year of the surveys in a region. These species represent a wide range of habitats and species types. As species distributions respond to many environmental and biological factors, combining data from multiple diverse species allows for a more complete picture of the general trends in marine species distribution. In order to more easily track and display changes in these distributions, the first year is standardized to zero. Thus, the indicator represents relative change in distribution from the first survey year.

Ecosystem Overfishing Time Series

The Ryther Index in the California Current ecosystem between 2016 and 2021 was substantially lower than historical patterns, though there is no trend in values.  

 

Indicator Source Information:

Landings are reported in tons of round (live) weight for all species or groups except univalve and bivalve mollusks, such as clams, mussels, oysters and scallops, which are reported as weight of meats (excludes shell weight). Landings data may sometimes differ from state-reported landings due to our reporting of mollusks in meat weights rather than gallons, shell weight, or bushels. Also, NMFS includes some species such as kelp and oysters that are sometimes reported by state agricultural agencies and may not be included with state fishery agency landings data.

 

Data Background and Caveats:

All landings summaries used in the compilation of this indicator only include non-confidential data. Federal statutes prohibit public disclosure of landings (or other information) that would allow identification of the data contributors and possibly put them at a competitive disadvantage. Most summarized landings here are non-confidential, but whenever confidential landings occur they have been combined with other landings and usually reported as "Withheld for Confidentiality" Total landings by state include confidential data and will be accurate, but landings reported by individual species may, in some instances, be misleading due to data confidentiality, which would be minimal given the aggregated nature of how these data were combined.

Landings data do not indicate the physical location of harvest but the location at which the landings either first crossed the dock or were reported from, as associated with major regions in the US

Many fishery products are gutted or otherwise processed while at sea and are landed in a product type other than round (whole) weight. Our data partners have standard conversion factors for the majority of the commonly caught species that convert their landing weights from any product type to whole weight. It is the whole weight that is displayed in our web site landing statistics. Caution should be exercised when using these statistics. An example of a potential problem is when landings statistics are used to monitor fishery quotas. In some situations, specific conversion factors may have been designated in fishery management plans or Federal rule making that differ from those historically used by NOAA Fisheries in reporting landings statistics.

Landings do not include aquaculture products except for clams, mussels and oysters.

Pacific landings summarized by state include an artificial “state” designation of “At-Sea Process, Pac.” This designation was assigned to landings consisting of primarily whiting caught in the EEZ off Washington and Oregon that were processed aboard large vessels while at sea. No Pacific state lists these fish on their trip tickets which are used to report state fishery landing, hence the at-sea processor designation was used to insure that they would be listed as a U.S. landing.

Landing summaries are compiled from data bases that overlap in time and geographic coverage, and come from both within and outside of NOAA Fisheries. 

Ecosystem overfishing metrics also have potential thresholds, usually for the Ryther Index of approximately 1; but we do not report Ryther index values here relative to any threshold.  Rather, we report the value of the indices for each region relative to their time series values.  Comparison to some regional reports may slightly differ due to the inclusion or exclusion of specific species, but the same general trends are observed and align.

Data Source:

Coastal employment numbers were downloaded from the NOAA ENOW Explorer Tool, filtered to present only coastal county values using the Census Bureau’s list of coastal counties within each state. ENOW Explorer streamlines the task of obtaining and comparing economic data, both county and state, for the six sectors dependent on the ocean and Great Lakes: living resources, marine construction, marine transportation, offshore mineral resources, ship and boat building, and tourism and recreation. Data are derived from Economics: National Ocean Watch (ENOW), available on NOAA’s Digital Coast. Of note is that these data fail to include self-employed individuals. Coastal county employment numbers were then summed within each region for reporting purposes.

Commercial Fishing Engagement

Between 2015 and 2020 the percent of communities moderately or highly engaged in commercial fishing showed an upward trend.

Graph of commercial fishing engagement index in the California Current region from 2009-2018

The x-axis on this time series represents years and the y-axis represents the percent of communities that are moderate to highly engaged in commercial fishing across California Current. Commercial fishing engagement is measured by the number permits, fish dealers, and vessel landings across California Current. 

 

Description of time series:

This time series shows the percent of communities moderately or highly engaged in commercial fishing in California Current from 2009 to 2020. Between 2015 and 2020 the percent of communities moderately or highly engaged in commercial fishing showed an upward trend.

 

Description of California Current Commercial Fishing Engagement:

Commercial fishing engagement is measured by the presence of fishing activity in coastal communities. The commercial engagement index is measured through permits, fish dealers, and vessel landings. A high rank within these indicates more engagement in fisheries. For details on both data sources and indicator development, please see https://www.fisheries.noaa.gov/national/socioeconomics/social-indicator….

 

NOAA Monitors commercial fishing engagement to better understand the social and economic impacts of fishing policies and regulations on our nation’s vital fishing communities. This and other social indicators help assess a coastal community’s resilience. NOAA works with state and local partners to monitor these indicators. We present data from the Northeast, Southeast, Gulf of Mexico, California Current, Alaska, and Hawaiian Island regions.

 

Data Source:

Commercial fishing engagement data is from the National Marine Fisheries Service’s social indicator data portal:https://www.st.nmfs.noaa.gov/data-and-tools/social-indicators/ The percentage of all communities in each region classified as medium, medium high, or highly engaged is presented for both recreational and commercial fishing.

Beach Closures

During the last five years, values have remained within the 10th and 90th percentiles of all observed data in the time series and there is no trend up or down.

graph of EPA-mandated beach closures for the California Current region from 1980-2020

Beach closures are the number of days when beach water quality is determined to be unsafe.

 

Data Interpretation:

Time series: This time series shows the average number of beach closure days in the California Current region from 2000 to 2022.  During the last five years, values have remained within the 10th and 90th percentiles of all observed data in the time series and there is no trend up or down.

 

Indicator and source information:

Unsafe water quality may have significant impacts on human health, local economies, and the ecosystem. Beach water quality is determined by the concentration of bacteria in the water (either Enterococcus sp. or Escherichia coli). 

 

The US Environmental Protection Agency (EPA) supports coastal states, counties and tribes in monitoring beach water quality, and notifying the public when beaches must be closed. The information presented is from states, counties, and tribes that submit data to the EPA Beach Program reporting database (BEACON). Data obtained from the EPA BEACON 2.0 website have been provided to EPA by the coastal and Great Lakes states, tribes and territories that receive grants under the BEACH Act. Data were refined to closure, by state or territory, by year.

 

Data background and limitations:

Data compiled by states or territories are combined in regions defined as US Large Marine Ecosystems (LME). Changes in the number of beach closure days may be driven by changes in the number of beaches monitored under the BEACH Act versus by state and local municipalities and not by changes in water and/or air quality. Not all US beach closures are captured in this database, because not all beaches in a state or territory are monitored through the EPA BEACH Act. Data that were not identified to a water body or identified as inland water were not included. Data for beaches monitored by state and local municipalities are not included. 

Data from 2020 may be inflated by the Covid-19 pandemic, as there was no consistent way for states to report pandemic-related closures.

 

Billion-Dollar Disasters

The number of disasters over the past 5 years is substantially higher than historical levels of events, and there is a significant increasing trend in the number of events.

graph of billion-dollar storm events for the California Current region from 1980-2020

Values correspond to the number of events in a given year

 

Time Series

The number of billion dollar disasters within the California Current ecosystem is quite variable over time, generally fluctuating between zero and four disasters a year. The number of disasters over the past 5 years is substantially higher than historical levels of events, and there is a significant increasing trend in the number of events.

 

Indicator Source Information:

Billion dollar disaster event frequency data are taken from NOAA’s National Centers for Environmental Information. The number of disasters within each region were summed for every year of available data. Although the number is the count of unique disaster events within a region, the same disaster can impact multiple regions, meaning a sum across regions will overestimate the unique number of disasters.

 

Data Background and Caveats:

Events are included if they are estimated to cause more than one billion U.S. dollars in direct losses. The cost estimates of these events are adjusted for inflation using the Consumer Price Index (CPI) and are based on costs documented in several Federal and private-sector databases.

DisMAP provides access to distribution information for more than 800 marine species caught in NOAA Fisheries bottom trawl surveys in five regions in the United States (Northeast, Southeast, Gulf of Mexico, West Coast, and Alaska). In this first version of the portal all species distribution products are derived from NOAA Fisheries regional bottom trawl survey data. They do not take into account alternative sources of fisheries data such as long-line, plankton, video, or fishery-dependent surveys. Because of this, distribution products are not available for the Pacific Islands or Caribbean regions at this time as those regions do not have bottom-trawl surveys; however incorporating these additional data sources is an area of interest for future releases.
