Tiny ocean waves could make large ice shelves crumble

Blog—  Small ocean waves could play a bigger role in breaking up ice shelves than tsunamis or other large waves, a new study suggests. A new study examining vibrations in Antarctica’s Ross Ice Shelf finds small waves continuously impacting the ice shelf may create enough strain to extend existing cracks.... more

Powerful Pacific Forces Disrupt the California Current

Sarah Witman, Freelance Writer

From Research Spotlights— Scientists create a 66-year data record to shed light on the role of El Niño in the California Current System’s shifting temperatures. Over time, the overall climate in the tropical Pacific Ocean cycles between warm and cool temperatures. This cyclical pattern, which.... more

How hurricane winds affect oceanic circulation on the continental shelf

Editor’s Highlight—   As the 2012 storm, Hurricane Sandy, crossed the Mid Atlantic Bight continental shelf, there was significant and rapid offshore advection of the bottom Cold Pool. This paper combines ocean observations during the hurricane with state of the art instrumentation and gliders to identify.... more

Bridging the gap between cyclone wind and wave by C-band SAR measurements

Editor’s Highlight—   The fact that tropical cyclone and hurricane and typhoon driven oceanic surface gravity wave periods and significant wave heights can be directly obtained from C-band radar is a significant advance. Also, the distribution of the mechanically wind-driven wave field and the wind.... more

Runup of landslide generated tsunamis on planar coasts and conical islands

Editor’s Highlight—   The manuscript describes a 3D experimental study on the generation, propagation and runup of landslide tsunamis. The experiments were done using two different landslide materials (gravel and cobble) and on two different beach types (planar and conical). This pushes forward the.... more

A Benchmark for Trace Greenhouse Gases in the Arctic Ocean

Terri Cook, Freelance Writer

From Research Spotlights— Samples of seawater from the North American Arctic show that the region is neither a major source nor sink of methane and nitrous oxide to the overlying atmosphere.  Although the concentrations of nitrous oxide and methane in Earth’s atmosphere have increased substantially.... more

Biogeochemical sensor performance in the SOCCOM profiling float array

Editor’s Highlight— The present-day capability to remotely observe biogeochemical parameters over the water column is a critical issue. This paper describes the performances of a suite of sensors monitoring and observing the biogeochemistry of Southern Ocean, specifically gathering data on oxygen,.... more

Modeling Ocean Waves over Rocky Reefs

Sarah Witman, Freelance Writer

From Research Spotlights— A field survey in Australia links rugged seafloor terrain to erosion-causing waves.  For many beachgoers, the cyclical nature of gently rolling and crashing waves is a soothing sight. But to oceanographers (and perhaps some surfers), the behavior of ocean waves is.... more
