Most of the U.S. estuaries in a national monitoring network have warmed, grown more algae and lost oxygen over the past two decades, a research team led by Kaitlin L. Reinl of Rensselaer Polytechnic…

The eastern Ross Sea off Antarctica went through an extreme marine heatwave in the southern summer of 2022–23 and then grew its largest plankton bloom since satellite measurements of ocean color…

Some lobster and razor clam products sold in shops and restaurants in Asturias, northern Spain, are cheaper American species carrying the name of a local one, a DNA survey published Sept. 6 in the…

Microbes in the eastern Mediterranean take up at least as much phosphorus from organic molecules as they do from phosphate, the mineral form dissolved in seawater, according to tracer measurements…

Until now, a Brazilian who wanted to know how much oil had been spilled along their own coast had to know which agency to ask, and then ask several more. The records existed. They were held in…

Researchers at Scripps Institution of Oceanography and CNRS have used six years of elephant seal dive data to show that small-scale ocean currents, known to churn the surface, are also active…

Oil on water does something a radar satellite can see. A slick flattens the small wind-driven ripples that bounce radar back to the spacecraft, so the sea beneath it returns almost nothing and the…

Climate-driven change in the deep seabed of the equatorial Pacific, where companies plan to mine polymetallic nodules, will rarely be distinguishable from natural variability by 2035, and had begun…

Tropical cyclones that cross oceans where the sea surface temperature varies little from kilometer to kilometer reach about 40% higher intensity than storms crossing water with sharp temperature…

A research team at Hokkaido University has published global maps estimating how much silicate, nitrate and carbon sink out of the sunlit surface ocean each year, and how much is carried back up. The…

Ocean heat extremes and spells of unusually low ocean productivity each raise the odds of a very poor fishing year in a given place, and the odds rise furthest when the two arrive together, according…

A survey of the northern Gulf of Mexico has found that 70 bottom simulating reflections (the seismic echo geologists use to trace how deep methane hydrate reaches beneath the seafloor) do not…
