Extreme Climate

Extreme Climate

Extreme climatic events such as unusually severe storms and droughts can have profound consequences for life both on land and in the ocean. Woods Hole Oceanographic Institution climate scientist Caroline Ummenhofer studies the ocean’s role in the global water cycle and its effects on extreme weather and climate.

To Forecast Rain, Look to the Ocean

To Forecast Rain, Look to the Ocean

Ever since humans have existed on Earth, they have looked to the heavens to forecast rain. But more reliable clues may lie in the ocean. New research by scientists at…

The Hotspot for Marine Life

The Hotspot for Marine Life

The continental shelfbreak in the waters off New England is an area where a spectacular abundance and diversity of marine life aggregate year-round. The Pioneer Array, a part of the NSF-funded Ocean Observatories Initiative, was placed there to help scientists explore the processes that make the shelfbreak so productive.

Antarctic Bottom Waters Freshening at Unexpected Rate

Antarctic Bottom Waters Freshening at Unexpected Rate

In the cold depths along the sea floor, Antarctic Bottom Waters are part of a critical part of the global circulatory system. Over the last decade, scientists have been monitoring changes in these waters, but a new WHOI study suggests these changes are themselves shifting in unexpected ways, with potentially significant consequences for the ocean and climate.

Salty Oceans Can Forecast Rain on Land

Salty Oceans Can Forecast Rain on Land

At this week’s American Geophysical Union meeting, a team of researchers from the Woods Hole Oceanographic Institution (WHOI) presented their latest research findings on the long-range predictions of rainfall on land. Their method is based on ocean salinity rather than sea surface temperatures, which has been the standard for decades.

Warming Ocean Drove Catastrophic Australian Floods

Warming Ocean Drove Catastrophic Australian Floods

New research by Woods Hole Oceanographic Institution physical oceanographer Caroline Ummenhofer and Australian scientists suggests that long-term warming of the Indian and Pacific Oceans is increasing the risk of heavy rains in the region.

Fishermen, Scientists Collaborate to Collect Climate Data

Fishermen, Scientists Collaborate to Collect Climate Data

To help understand the ongoing changes in their slice of the ocean, a group of commerical fishermen in southern New England are now part of a fleet gathering much-needed climate data for scientists through a partnership with the Commercial Fisheries Research Foundation (CFRF) and Woods Hole Oceanographic Institution (WHOI).

Study Offers Clues to Better Rainfall Predictions

Study Offers Clues to Better Rainfall Predictions

WHOI scientists have found a potential path to better seasonal rainfall predictions. Their study shows a clear link between higher sea surface salinity levels in the North Atlantic Ocean and increased rainfall on land in the West African Sahel, the area between the Sahara Desert and the savannah in Sudan.

Fiamma Straneo Selected for Prestigious Sverdrup Lecture

Fiamma Straneo

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.

Warming Ocean Worsened Australia’s Fatal 2010/2011 Floods

flood

A study by a team of U.S. and Australian researchers shows that long-term warming of the Indian and Pacific oceans played an important role in increasing the severity of the devastating floods that struck Australia in 2010/2011. The study was published in Geophysical Research Letters.

Ice, Wind & Fury

Greenlanders are well away of piteraqs, the hazardous torrents of cold air that sweep down off the ice cap. But scientists are just beginning to unravel how and when piteraqs form.

New Study Projects That Melting of Antarctic Ice Shelves Will Intensify

New 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.

Sudden 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.
