An article by Jeff Tollefson in the November 16 edition of Nature magazine, "How much longer can Antarctica’s hostile ocean delay global warming?," features SOCCOM researchers Joellen (leader of the SOCCOM modeling group), Ken Johnson (SOCCOM Associate Director), and Jorge Sarmiento (SOCCOM director).  

Joellen Russell wasn’t prepared for the 10-metre waves that pounded her research vessel during an expedition south of New Zealand. “It felt like the ship would be crushed each time we rolled into a mountain of water,” recalls Russell, an ocean modeller at the University of Arizona in Tucson. At one point, she was nearly carried overboard by a rogue wave.

​(Do some technical difficulties, the recording of this event is not yet available)


At no time has a clear picture of our oceans' health been more important than now, as the international agreement reached in Paris to limit and reduce our carbon emissions goes into effect November 4.

That picture is coming into greater focus as scientists studying the Southern Ocean through the NSF-funded SOCCOM project begin analyzing data gathered by more than four dozen robotic floats deployed into this critically important body of water that encircles Antarctica. 

Join us Tuesday, October 25, at 2:30 pm EDT (11:30 am PDT) as leading oceanographers discuss the latest, and sometimes surprising, findings coming from their SOCCOM research.

Peering into the insides of a machine can be a useful way to learn about how it works. MBARI researchers Ken Johnson and Hans Jannasch created a transparent version of a profiling float, an instrument that makes biogeochemical measurements in the ocean, for educational purposes. To make the clear float, Jannasch collected old, discarded parts at MBARI and from partners at the University of Washington, and replaced the yellow outer casing of the float with a transparent PVC tube.

The inner parts are labeled and there are two cutaway elements—one to see the flow-cell, a device that allows seawater to be pumped over the sensors and shields the pH sensor from light, and another to see the bladder that inflates and deflates to allow the float to sink to the bottom and rise through the upper 2,000 meters of the open ocean, collecting measurements along the way. Jannasch, hailing from Germany, painted the cutaways red, a technique he remembers from his childhood when he saw an exhibit of a train that was cut in half in the Deutsches Museum in Munich.

Research at the intersection of ocean physics and biogeochemistry in the Program in Atmospheric and Oceanic Sciences (AOS) at Princeton University

 AOS Princeton
The AOS Program’s ocean biogeochemistry group seeks energetic and enthusiastic postdoctoral or more senior researchers to participate in process-oriented studies using theory, modeling, and observations to develop understanding at the intersection of ocean physics and biogeochemistry. This effort is part of a broad study of ocean circulation, the global carbon cycle, and climate change. Of particular interest is how ocean dynamics at a range of spatial scales - from submesoscale/mesoscale fronts and eddies to regional, basin, and global scale circulations - impacts the cycling of carbon, nutrients, and oxygen, with an emphasis on the Southern Ocean.

Antarctic sea ice is constantly on the move as powerful winds blow it away from the coast and out toward the open ocean. A new study shows how that ice migration may be more important for the global ocean circulation than anyone realized.

A team of scientists used a computer model to synthesize millions of ocean and ice observations collected over six years near Antarctica and estimated, for the first time, the influence of sea ice, glacier ice, precipitation and heating on ocean overturning circulation. Overturning circulation brings deep water and nutrients up to the surface, carries surface water down, and distributes heat and helps store carbon dioxide as it flows through the world’s oceans, making it an important force in the global climate system. The scientists found that freshwater played the most powerful role in changing water density, which drives circulation, and that melting of wind-blown sea ice contributed 10 times more freshwater than melting of land-based glaciers did.

Float Deployment

As global climate change accelerates with increasingly substantial impacts on communities worldwide, the need to understand and make reliable projections of future climate becomes ever more imperative.

The National Science Foundation-funded Southern Ocean Carbon and Climate Observations and Modeling, or SOCCOM, project is meeting this need by deploying 200 robotic floats in the Southern Ocean surrounding Antarctica to capture real-time biological, geological and chemical (often called "biogeochemical") data.

With the help of CyVerse, the NSF-funded and University of Arizona-led national data management project, SOCCOM hopes soon to expand the network of floats to monitor carbon cycling throughout the world's swiftly changing oceans.

An update on SOCCOM accomplishments was featured in the May 1, 2016 edition of the SOOS Newsletter.

The Southern Ocean Carbon & Climate Observations and Modeling (SOCCOM) Project is in its second season of deploying autonomous biogeochemical floats to make sustained observations of the carbon cycle.  SOCCOM is a six-year initiative to transform our understanding of the Southern Ocean by creating a network of these robotic floats, as well as carrying out shipboard measurements, instrument and sensor development, and data analysis, including state estimation in conjunction with a high-resolution earth system modeling program. SOCCOM is funded by the National Science Foundation’s Division of Polar Programs, with additional support from NOAA and NASA.
