Webb21 sep. 2024 · We present here a review of seven key ocean climate change indicators: (i) Sea Surface Temperature, (ii) Ocean Heat Content, (iii) Global Mean Sea level, (iv) Ocean pH, (v) Dissolved oxygen concentration (vi) Arctic Sea Ice extent, thickness, and volume and (vii) the strength of the Atlantic Meridional Overturning Circulation (AMOC). WebbWe found that the river plume extended to 30 m depth near the Mississippi Delta, to 10-20 m depth in the eastern Gulf, and to 5-10 m depth in the Straits of Florida, with variations due to the presence of eddies (Androulidakis et al., 2024).
