From: Surface Water CO2 variability in the Gulf of Mexico (1996–2017)
EOF analysis of Mode 1 and Mode 2 (left panel) and Mode 1 and Mode 3 (right panel) for the coastal ocean (black symbols) and open ocean (gray symbols). The four parameters of the EOF analysis include sea surface salinity (sss, circles), sea surface temperature (sst, squares), sea surface partial pressure of CO2 (pCO2, stars) and temperature-normalized sea surface pCO2 (npCO2, triangles).
