Seagrass beds represent critical and threatened coastal habitats around the world, and a new University of Florida study shows how much sunlight seagrass needs to stay healthy.
A single strain of marine bacteria called Alteromonas may consume as much dissolved carbon in the ocean as an entire, diverse bacterial community, according to a new study.
The headwaters for Puget Sound’s famously rich waters lie far below the surface, in a submarine canyon that draws nutrient-rich water up from the deep ocean.
A decades-long debate over how nitrogen is removed from the ocean may now be settled by new findings from researchers at Princeton University and their collaborators at the University of Washington.
A fraction of the carbon that finds its way into Earth’s oceans — the black soot and charcoal residue of fires — stays there for thousands for years, and a new first-of-its-kind analysis shows how some black carbon breaks away and hitches a ride to the ocean floor on passing particles.
Before Malaysia Airlines Flight 370 went missing, sea trash was not a global headliner.
New research by Yale University scientists challenges a long-standing paradigm for temperature variability in the Pacific Ocean, casting doubt on the existence of a past period of “permanent” El Niño-like conditions and suggesting that the tropics could grow markedly hotter.
The Baltic Sea is suffering from a lack of oxygen. Poor oxygen conditions on the seabed are killing animals and plants, and experts are now sounding the alarm — releasing fewer nutrients into the Baltic Sea is absolutely necessary.
Natural fluctuations in the ocean temperature in the North Atlantic have a significant impact on the climate in the northern hemisphere.
Far beneath the surface of the ocean, deep currents act as conveyer belts, channeling heat, carbon, oxygen and nutrients around the globe.
