Climate change is an ever-pressing concern, with innovative ways to remove excess carbon from the atmosphere a continued focus of scientists. One such carbon sequestration method turns to an unlikely sink—seagrass—a marine ...
A trio of climatologists at the Southern Ocean Carbon–Climate Observatory, working with a colleague with the Coastal Systems and Earth Observation Research Group, all in South Africa, reports evidence that phytoplankton ...
Oceanic responses to climate and human interactions have been studied for decades. In recent years the effects of increasing ocean acidity have been featured, with stark images of coral reefs being decimated by bleaching.
A team of oceanographers at the Scripps Institution of Oceanography, working with a colleague from Chungnam National University and another from the University of Hawaii, has mapped 19,000 previously unknown undersea volcanoes ...
Hydrothermal vents have been identified as a previously undiscovered source of dissolved black carbon in the oceans, furthering our understanding of the role of oceans as a carbon sink.
