Scientists from the University of Sydney’s School of Geosciences have led the creation of the world’s first digital map of the seafloor’s geology. It is the first time the composition of the seafloor, covering 70 percent of Earth’s surface, has been mapped in 40 years; the most recent map was hand drawn in the 1970s.
Rivers transport 200 million tons of carbon to the oceans every year, according to new research that calculates the role of rivers in carbon storage.
Beyond the pounding surf loved by novelists and beachgoers alike, the ocean contains rolling internal waves beneath the surface that displace massive amounts of water and push heat and vital nutrients up from the deep ocean.
If you think rivers are what send terrestrial rainfall back into the oceans, you don’t know the half of it. And that fraction keeps shrinking.
A new study led by scientists at the Woods Hole Oceanographic Institution (WHOI) points to the deep ocean as a major source of dissolved iron in the central Pacific Ocean.
Human-induced changes to Earth’s carbon cycle — for example, rising atmospheric carbon dioxide and ocean acidification — have been observed for decades.
The first detailed, high-resolution 3-D maps of Antarctic sea ice have been developed using an underwater robot.
Using ocean observations and a large suite of climate models, Lawrence Livermore National Laboratory scientists have found that long-term salinity changes have a stronger influence on regional sea level changes than previously thought.
Humans appear to have done a thorough job of contaminating the Earth’s rivers, oceans and atmosphere, says Rachel Nuwer. Is there anywhere pristine left on the planet?

Scientists from the UMass Dartmouth School for Marine Science and Technology drove up to the Fairhaven Shipyard before dawn Tuesday with a bright yellow, 6-foot torpedo-shaped object they call Blue.
