Ocean science news, explainers, and statistics covering marine environments, currents, climate, coasts, seafloor research, and the changing global ocean.
A Communications Earth & Environment study led by researchers at Shanghai Jiao Tong University found that marine heatwaves often produce stronger daytime surface extremes than standard monitoring captures. The team reports that the daytime subskin sea surface temperature peak is typically 20 to 30% higher during these events, which can push the warmest part of…

Daily Arctic and Antarctic sea-ice extent from the NSIDC Sea Ice Index, with recent changes, charts, methodology, and limitations.
Salt stays behind when seawater evaporates. Rain, rivers, melting ice and currents redistribute fresh water. The balance of evaporation and rainfall gives the ocean a salt map instead of one uniform recipe. Across the five named ocean basins, the Atlantic Ocean is the saltiest on average. The answer describes a basin-wide comparison, which is why…
