UCSB researchers collaborate to track commercial fishing worldwide in real time.
A new study suggests that by 2050, most coral reefs around the world are at risk of experiencing constant depletion of one of their building blocks - calcium carbonate sediments.
More than half of the world's oceans are exposed to industrial fishing activities, a new study, conducted at unprecedented scale, reveals. Peak fishing activity, the study goes on to report, is more affected by cultural and political events such as holidays and closures than by changes in economic factors, or environmental ones.
A team led by geochemist Dr. Katharina Pahnke from Oldenburg has discovered important evidence that the rise in atmospheric carbon dioxide levels at the end of the last ice age was triggered by changes in the Antarctic Ocean.
The meteorological teleconnection pattern that covers most domains along the ancient Silk Road exerts significant influences on climatic anomalies over Eurasia. Scientists from the Institute of Atmospheric Physics, Chinese Academy of Sciences, previously found that there is a significant positive relationship between the Silk Road Pattern and the north-south displacement of the Asian jet. Subsequently, in a recent study published in Advances in Atmospheric Sciences, they demonstrate that this relationship is robust only in north-jet years.
Cyanobacteria -- which propel the ocean engine and help sustain marine life -- can shift their color like chameleons to match different colored light across the world's seas, according to research by an international collaboration including the University of Warwick.
A new analysis of the natural temperature archives stored in coral reefs shows the ocean around the Galápagos Islands has been warming since the 1970s. The finding surprised the research team, because the sparse instrumental records for sea surface temperature for that part of the eastern tropical Pacific Ocean did not show warming. Scientists thought strong upwelling of colder deep waters spared the region from the warming seen in other parts of the Pacific.
Pacific coast marshes, particularly those in California and Oregon, are highly vulnerable to climate change, according to a new modeling analysis. Under higher-range sea level rise scenarios estimated to impact this region by the end of the century, all high- and mid-marsh habitats are projected to be lost. Only the low marsh habitat is likely to survive under such
Through their grazing activity, sea urchins excavate rock and form the pits they occupy. This activity may cause significant bioerosion of temperate reefs, according to a study published Feb. 21, 2018 in the open-access journal PLOS ONE by Michael Russell from Villanova University, US, and colleagues.
Beluga whales that spend summers feeding in the Arctic are diving deeper and longer to find food than in earlier years, when sea ice covered more of the ocean for longer periods, according to a new analysis led by University of Washington researchers
