Geologic History of Ayeyawady River Delta Mapped for the First Time
The Ayeyawady River delta in Myanmar is home to millions of people, and is a hub of agricultural activity. Unlike other large rivers across the world, however, the Ayeyawady has been relatively untouched by large infrastructure and dam projects for the past 50 years, and its geologic evolution has never previously been studied.

Scientists have found lingering radioactivity in the lagoons of remote Marshall Island atolls in the Pacific Ocean where the United States conducted 66 nuclear weapons tests in the 1940s and […]
Read MoreFiamma Straneo Selected for Prestigious Sverdrup Lecture
The American Geophysical Union (AGU) has chosen Fiamma Straneo, a physical oceanographer at Woods Hole Oceanographic Institution (WHOI), to deliver the Sverdrup Lecture at this year’s meeting of the Ocean Sciences section held in New Orleans from February 21-26, 2016. The lecture is one of the highest awards the section bestows on its members.
Read MoreNew Study Projects That Melting of Antarctic Ice Shelves Will Intensify
New research published today projects a doubling of surface melting of Antarctic ice shelves by 2050 and by 2100 may surpass intensities associated with ice shelf collapse, if greenhouse gas emissions from fossil fuel consumption continues at the present rate.
Ice shelves are the floating extensions of the continent’s massive land-based ice sheets. While the melting or breakup of floating ice shelves does not directly raise sea level, ice shelves do have a “door stop” effect: They slow the flow of ice from glaciers and ice sheets into the ocean, where it melts and raises sea levels.

A new study by physical oceanographers at Woods Hole Oceanographic Institution (WHOI), published in the Journal of Geophysical Research, shows that water temperatures in this continental shelf region have been trending upward, with unprecedented warming occurring over the last 13 years. The study also suggests a connection between sea level anomalies and water temperature along the continental shelf.
Read MoreSudden Draining of Glacial Lakes Explained
In 2008 scientists from Woods Hole Oceanographic Institution (WHOI) and the University of Washington documented for the first time how the icy bottoms of lakes atop the Greenland Ice Sheet can crack open suddenly—draining the lakes completely within hours and sending torrents of water to the base of the ice sheet thousands of feet below. Now they have found a surprising mechanism that triggers the cracks.
Scientists had theorized that the sheer weight of the water in these supraglacial lakes applied pressure that eventually cracked the ice, but they could not explain why some lake bottoms cracked while others did not.

As the ocean ‘s pH decreases and acidifies, coral reefs are more likely to begin dissolving and “drown”. A new study shows exposing corals to added nutrients increases their erosion and dissolution rate tenfold.
