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.
Time series: The time series shows the integrated sea surface temperature across Lake Michigan. During the last five years there has been no notable trend and values were between the 10th and 90th percentile of all observed data in the time series.
Description of Sea Surface Temperature:
Sea surface temperature (SST) is defined as the temperature of the top few millimeters of the ocean. This temperature directly or indirectly impacts the rate of all physical, chemical, and most biological processes occurring in the ocean. SST is globally monitored by sensors on satellites, buoys, ships, ocean reference stations, autonomous underwater vehicles (AUVs) and other technologies.
SST monitoring tells us how the ocean and atmosphere interact, as well as providing fundamental data on the global climate system. This information also aids us in weather prediction, i.e. identifying the onset of El Niño and La Niña cycles - multiyear shifts in atmospheric pressure and wind speeds. These shifts affect ocean circulation, global weather patterns, and marine ecosystems. SST anomalies have been linked to shifting marine resources. With warming temperatures, we observe the poleward movements of fish and other species. Temperature extremes—both ocean heatwaves and cold spells—have been linked to coral bleaching as well as fishery and aquaculture mortality. We present the annual average SST in all regions.
Lake Michigan Description
Lake Michigan is the third largest Great Lake and has a water surface area of 57,573 square kilometers or 22,300 square miles. Unlike the other four Great Lakes, Lake Michigan is entirely within the United States. Roughly 12 million people live along the shores of Lake Michigan. (While Lakes Michigan and Huron are often referred to as two separate lakes, technically they are one hydrologic system connected by the Straits of Mackinac.)
Great Lakes SST data were accessed from (https://coastwatch.glerl.noaa.gov/glsea/glsea.html).
The data are plotted in degrees Celsius.
