The Southern Ocean Carbon and Climate Observations and Modeling (SOCCOM) project’s mission is to drive a transformative shift in the scientific and public understanding of the role of the vast Southern Ocean in climate change and biogeochemistry. The Southern Ocean consists of the World Ocean's southernmost waters, generally considered south of 60° S latitude and encircling Antarctica. Important and unique phenomena occur within and around the Southern Ocean. Highlights include:
Because of its remoteness, large numbers of sophisticated robotic sensor arrays are needed to study the Southern Ocean. SOCCOM, housed at Princeton University and administered by the Princeton Environmental Institute, is deploying a robotic observing system composed of about 200 autonomous floats. The robotic observing system will provide nearly continuous coverage in time and horizontal space over the entire Southern Ocean and vertical coverage deep into the water column (Figure 1).

These floats and their operation are required to have four essential characteristics:
SOCCOM will provide the observational data needed to analyze and improve a new generation of high-resolution earth system models to increase understanding of the Southern Ocean’s current workings and make better projections of Earth’s future trajectory’s climate and biogeochemistry.
Jeff has been writing about power electronics, electronic components, and other technology topics for over 30 years. He started writing about power electronics as a Senior Editor at EETimes. He founded Powertechniques, a power electronics design magazine with a monthly circulation of over 30,000. He subsequently founded Darnell Group, a global power electronics research and publishing firm. Among its activities, Darnell Group published PowerPulse.net, which provided daily news for the global power electronics engineering community. He is the author of a switch-mode power supply textbook, titled “Power Supplies,” published by the Reston division of Prentice Hall.
Jeff was co-founder of Jeta Power Systems, a maker of high-wattage switching power supplies acquired by Computer Products. Jeff is also an inventor. His name is on 17 U.S. patents in the fields of thermal energy harvesting and optical metamaterials. He is an industry source and frequent speaker on global trends in power electronics. He has been invited to speak at numerous industry events, including the Plenary Session of the IEEE Applied Power Electronics Conference, Semicon West, Global Semiconductor Alliance Emerging Opportunities Conference, IBM Power and Cooling Symposium, and Delta Electronics Senior Staff Seminar on Global Telecommunications Power. Jeff has a Masters Degree in Quantitative Methods and Mathematics from the University of California, Berkeley.
