We also investigate the trends in mesoscale eddies using three parameters to identify ocean-eddy-related energetic features in their area, strength, and intensity. Multidecadal remote-sensing-based observations of monthly SST, Chl-a, and sea surface height are used to detect trends at both basin and grid scales. Prominent warming trends are found in most regions of the GoM in all months, with the largest trends in the northern GoM. Winter cooling trends are also detected along the Texas and Florida coast. The overall summer warming trend (~0.22 \u00b0C\/decade) is larger than the winter trend (~0.05 \u00b0C\/decade), suggesting seasonal variations of increase in SST with warming. Chl-a trends and variations are confined on the continental shelf and slope in the northern GoM. The largest increase trends are found near the Mississippi River Delta. No obvious Chl-a trend is detected in the deepwater of the GoM, consistent with previous studies. Small but significant changes are found in eddy characteristics, indicating the eddy activities might be slowly affected by climate change in the GoM. The detailed monthly trends at per-grid scale are valuable for regional resource management, environmental protection, and policy making in the GoM.<\/jats:p>","DOI":"10.3390\/rs14153754","type":"journal-article","created":{"date-parts":[[2022,8,9]],"date-time":"2022-08-09T04:16:55Z","timestamp":1660018615000},"page":"3754","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["Multidecade Trends of Sea Surface Temperature, Chlorophyll-a Concentration, and Ocean Eddies in the Gulf of Mexico"],"prefix":"10.3390","volume":"14","author":[{"given":"Geng","family":"Li","sequence":"first","affiliation":[{"name":"Department of Civil and Environmental Engineering, University of Missouri, Columbia, MO 65211, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3727-1379","authenticated-orcid":false,"given":"Zhankun","family":"Wang","sequence":"additional","affiliation":[{"name":"Northern Gulf Institute, Mississippi State University, Stennis Space Center, MS 39529, USA"},{"name":"National Centers for Environmental Information (NCEI), NOAA, Stennis Space Center, MS 39529, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3799-2042","authenticated-orcid":false,"given":"Binbin","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Civil and Environmental Engineering, University of Missouri, Columbia, MO 65211, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,8,5]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"508","DOI":"10.1038\/nature14491","article-title":"Ocean impact on decadal Atlantic climate variability revealed by sea-level observations","volume":"521","author":"McCarthy","year":"2015","journal-title":"Nature"},{"key":"ref_2","first-page":"9","article-title":"An overview of the northern Gulf of Mexico ecosystem","volume":"33","author":"Spies","year":"2016","journal-title":"Gulf Mex.
