Rice University and Georgia Tech scientists use data from ancient coral to build a record of temperatures in the tropical Pacific Ocean over the last millennium. The data question previous links between volcanic eruptions and El Niño events.
For the first time, researchers have documented seasonal migrations of fishes across the deep seafloor, revealing an important insight that will further scientific understanding of the nature of our planet.
If circulation of deep waters in the Atlantic stops or slows due to climate change, it could cause cooling in northern North America and Europe - a scenario that has occurred during past cold glacial periods. Now, a Rutgers coauthored study suggests that short-term disruptions of deep ocean circulation occurred during warm interglacial periods in the last 450,000 years, and may happen again.
In the future's warmer climate, large, abrupt and frequent changes in ocean ventilation may be more likely than currently assumed, according to a new study.
A global analysis of over 300 marine species spanning more than 100 years, shows that mammals, plankton, fish, plants and seabirds have been changing in abundance as our climate warms.
Years of cloud data over a shipping route between Europe and South Africa shows that pollution from ships has significantly increased the reflectivity of the clouds. More generally, the results suggest that industrial pollution's effect on clouds has masked about a third of the warming due to fossil fuel burning since the late 1800s.
If artificial light shines into the Arctic Ocean during the polar night, does it matter? A new paper in Communications Biology says the answer to this is a strong yes.
Dr Celia Schunter from the School of Biological Sciences at The University of Hong Kong and a team of international scientists conducted a study to understand the molecular response of five species to the 2016 heatwave conditions that killed a third of the Great Barrier Reef corals. This is the world-first study tracking how wild fish populations respond to a severe marine heatwave. The results of the study were published in Science Advances.
A previously unknown significant source of carbon just discovered in the Arctic has scientists marveling at a once overlooked contributor to local coastal ecosystems -- and concerned about what it may mean in an era of climate change.
The oceans are a very important reservoir for carbon in the system of the earth. However, many aspects of the marine carbon cycle are still unknown. Scientists from Bremen and Bremerhaven now found that sugar plays an important role in this process. At the same time, the sweet energy source is important for the ecosystem of the oceans.
