New study challenges long-held tsunami formation theory

Blog— A new study is challenging a long-held theory that tsunamis form and acquire their energy mostly from vertical movement of the seafloor. An undisputed fact was that most tsunamis result from a massive shifting of the seafloor — usually from the subduction, or sliding, of one tectonic plate under.... more

Researchers unravel drivers of large iceberg movement

Blog— When, in the foreseeable future, a tabular iceberg nearly seven times the size of Berlin breaks off the Larsen C Ice Shelf in the Antarctic, it will begin a journey, the course of which climate researchers at the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research can accurately.... more

Dam Discharge Events Alter Water Flow in an Estuary in Spain

Sarah Stanley, Freelance Writer

From Research Spotlights—   Three-year observations suggest that increased sediment concentrations inhibit vertical transfer of momentum between water layers for more than 2 months after a high-discharge event.  The Guadalquivir River empties into the Atlantic near Seville on the southwest.... more

Big Storms Pump Mediterranean Water Far into the Black Sea

Sarah Stanley, Freelance Writer

From Research Spotlights— For the first time, scientists provide a sea-wide view of what happens to Mediterranean waters that flow into the Black Sea through the Bosporus Strait.  Below a depth of about 150 meters, the Black Sea is devoid of oxygen. Only certain microbes can survive in this.... more

How “Godzilla” El Niño Affected Tropical Fish in Low-Oxygen Zone

Emily Underwood, Freelance Writer

From Research Spotlights— A warm period unexpectedly boosted some species of fish larvae off the coast of Mexico.  It’s been a weird past few years for the Pacific Ocean, thanks to rising global temperatures. First, there was “The Blob,” a mass of warm water that hit the West Coast of the.... more

Mysterious Intraseasonal Oscillations in Monsoons

Sarah Witman, Freelance Writer

From Research Spotlights— The unpredictable cycles of rainfall during India’s summer-long monsoon have stymied scientists for decades.  India’s summer monsoon is a major event, single-handedly supplying water for agriculture across all of southern Asia. Because of its widespread effect on.... more

How Arctic Ice Affects Gas Exchange Between Air and Sea

Sarah Stanley, Freelance Writer

From Research Spotlights— Scientists begin to fill a major data gap by investigating carbon dioxide dynamics in a remote region of the Arctic Ocean.  Climate change is rapidly transforming the world’s oceans, and researchers are scrambling to understand what that means for the physical and.... more

How the Deep, Cold Currents of the Labrador Sea Affect Climate

Emily Underwood, Freelance Writer

From Research Spotlights—Seventeen years of ocean current data link global atmospheric and oceanic circulation. Late winter deep water formation in the Nordic Seas north of Iceland and in the Labrador Sea between the coasts of Greenland and Canada produces cold and well-ventilated deep water..... more

Observations of waves and currents during barrier island inundation

Editors’ Highlight—This paper describes field observations of overwash and inundation caused by storms across a barrier island in The Netherlands. Using a comprehensive set of data on water levels, waves, winds and currents the authors found different forcing and dissipation mechanisms from each side.... more
