Evidence of Sea-level Change in Southeast Asia 6,000 Years Ago Has Implications for Today's Coastal Dwellers, Rutgers Study Finds

For the 100 million people who live within 3 feet of sea level in East and Southeast Asia, the news that sea level in their region fluctuated wildly more than 6,000 years ago is important, according to research published by a team of ocean scientists and statisticians, including Rutge

Gas Hydrate Breakdown Unlikely to Cause Massive Greenhouse Gas Release

A recent interpretive review of scientific literature performed by the U.S. Geological Survey and the University of Rochester sheds light on the interactions of gas hydrates and climate. The breakdown of methane hydrates due to warming climate is unlikely to lead to massive amounts of

A warm relationship between corals and bacteria

Bacteria in certain microbiomes appear to help corals adapt to higher water temperatures and protect against bleaching, as shown by a KAUST-led research team. Coral animals rely on algal and bacterial symbionts, known as their microbiome, to function and thrive. These mutually benefic

Long-term impacts of deep-sea mineral mining

A new international study has demonstrated that deep-sea nodule mining will cause long-lasting damage to deep-sea life. This study, led by scientists at the National Oceanography Centre (NOC), was the first to review all the available information on the impacts of small-scale sea-floo

Decoding Ocean Signals

Geographer Tim DeVries and colleagues determine why the ocean has absorbed more carbon over the past decade. With the ocean absorbing more carbon dioxide (CO2) over the past decade, less of the greenhouse gas is reaching the Earth’s atmosphere. That’s decidedly good news, but it comes

Organic matter composition found to be critical factor in mercury methylation

The biological formation of neurotoxic methyl mercury is an enigmatic process underpinning mercury-related health and environmental hazards. Nevertheless, the exact mechanisms and the factors controlling the process are still not well understood. In a collaborative effort, researchers

UCI, NASA reveal new details of Greenland ice loss

Less than a year after the first research flight kicked off NASA’s Oceans Melting Greenland campaign, data from the new program are providing a dramatic increase in knowledge of how Greenland’s ice sheet is melting from below. Two new research papers in the journal Oceanography, inclu

Lakes respond differently to nitrogen disposition

Nitrogen deposition caused by human activities can lead to an increased phytoplankton production in boreal lakes. The response of boreal lakes to nitrogen deposition will strongly depend on each lake’s content of organic carbon, which are predicted to increase with future warmer and w

High Selenium Levels Found in Fish in N.C. Lakes Receiving Coal Ash Waste

A new Duke University study has found high levels of selenium in fish in three North Carolina lakes receiving power plants’ coal ash waste. “Across the board, we’re seeing elevated selenium levels in fish from lakes affected by coal combustion residual effluents,” said Jessica Brandt,
