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 on the impacts of climate change on ocean circulation, biogeochemistry, and ecology in the Program in Atmospheric and Oceanic Sciences (AOS) at Princeton University 

AOS PrincetonThe AOS ocean biogeochemistry group seeks energetic and enthusiastic postdoctoral researchers to participate in modeling and observational studies of climate impacts on ocean circulation and how these affect ocean biogeochemical cycles and ecology. This effort is part of a broad modeling and observational study of ocean circulation, the global carbon cycle, ocean ecology, and the impact of climate change on all of these. Areas of particular current interest include the Southern Ocean, and the detection and attribution of biogeochemical and ecological change in the 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.

The Southern Ocean guards its secrets well. Strong winds and punishing waves have kept all except the hardiest sailors at bay. But a new generation of robotic explorers is helping scientists to document the region’s influence on the global climate. These devices are leading a technological wave that could soon give researchers unprecedented access to oceans worldwide.
