First direct evidence of ocean mixing across the gulf stream
New research provides the first direct evidence for the Gulf Stream blender effect, identifying a new mechanism of mixing water across the swift-moving current. The results have important implications for weather, climate and fisheries because ocean mixing plays a critical role in these processes. The Gulf Stream is one of the largest drivers of climate and biological productivity from Florida to Newfoundland and along the western coast of Europe.
WHOI researcher dives to Challenger Deep
As a Taiwanese-American, Dr. Lin’s dive marked the first time a person of Asian descent had traveled to the bottom of the Mariana Trench.
Dynamics of the Tropical Atmosphere and Oceans

There is no escaping from climate change, even in the deep sea
Hokkaido University Even though the deeper layers of the ocean are warming at a slower pace than the surface, animals living in the deep ocean are more exposed to climate warming and will face increasing challenges to maintain their preferred thermal habitats in the future. Reporting in the journal Nature Climate Change, an international team…
Study: Ancient ocean oxygen levels associated with changing atmospheric carbon dioxide
A Texas A&M-led study analyzed ocean floor sediment cores to provide new insights into the relationship between deep ocean oxygenation and atmospheric carbon dioxide levels in the 50,000 years before the last ice age Texas A&M UniversityShare Print E-Mail Why do carbon dioxide levels in the atmosphere wax and wane in conjunction with the warm and cold…
HKU marine biologist and international team unveil impacts of heatwave on reef fishes
The University of Hong Kong The marine heatwave of 2016 was one of longest and hottest thermal anomalies recorded on the Great Barrier Reef in Australia, influencing multiple species of marine ectotherms, including coral reef fishes. Dr Celia Schunter from School of Biological Sciences and the Swire Institute of Marine Science (SWIMS), The University of…
Climate change could threaten sea snails in mid-Atlantic waters
Common whelk live in one of the fastest warming marine areas, Rutgers-led study says Rutgers University An adult whelk collected aboard a commercial scallop vessel.

Global cooling after nuclear war would harm ocean life
Seafood production also may be impacted by increased acidification Rutgers University Corals, which are threatened by global climate change and ocean acidification, support a wide range of reef fish at Baker reef in the Pacific Remote Islands.

‘Blob’ research shows ecological effects that halted fishing and hiked whale entanglements
Unprecedented environmental changes inspire new online tools to better spot them next time NOAA Fisheries West Coast Region An ecological pileup of unprecedented changes in the ocean off the West Coast beginning about 2014 led to record entanglements of humpback and other whales, putting the region’s most valuable commercial fishery at risk, new research shows.…
