As SOCCOM completes its sixth year and embarks on its renewal funding, we are eager to collect our cutting-edge research in a special publication. The AGU has a new approach—the ’Special Collection’—which allows scientists to choose the most suitable AGU journal for the research. Our special collection, "Southern Ocean and Climate: Biogeochemical and Physical Fluxes and Processes," includes

AGU Advances 
Geophysical Research Letters
JGR Oceans 
Global Biogeochemical Cycles
Journal of Advances in Modeling Earth Systems (JAMES)

In April 2018, an autonomous yellow float was launched in the Weddell Sea by the Southern Ocean Carbon and Climate Observations and Modeling Project (SOCCOM). Its name is Cheerwine, thanks to McDougle Middle School (MMS) Science Teacher, Christine Lippy’s students, who participated in an international Adopt-a-Float program.  On December 2, after a two year delay, Dr. Bob Key, one of the lead scientists of the SOCCOM program, paid virtual visits to all three grade levels of MMS students to talk about Cheerwine, climate change and the Southern Ocean, and to answer a wide range of thoughtful and excited questions.

BGC floats are going global!  The National Science Foundation has announced the award of a $53 million grant to expand SOCCOM's pilot biogeochemical float array to the global ocean - see the Science story below:

Fleet of robotic probes will monitor global warming’s impact on microscopic ocean life

A single drop of seawater holds millions of phytoplankton, a mix of algae, bacteria, and protocellular creatures. Across the world’s oceans these photosynthesizing microbes pump out more than half of the planet’s oxygen, while slowing climate change by capturing an estimated 25% of the carbon dioxide (CO2) released from humanity’s burning of fossil fuels. But the scale of this vital chemistry is mostly a guess, and there’s little sense of how it will change as temperatures rise. “What’s happening out there? We have no idea really,” says Susan Wijffels, a physical oceanographer at the Woods Hole Oceanographic Institution. [read more]

In a new paper in Geophysical Research Letters, SOCCOM researcher Alex Haumann and colleagues used rather sparse traditional ship‐based observations with data collected by autonomous floats and instrumented marine mammals to detect and analyze where, when, and how supercooled seawater forms in the Southern Ocean. They detected sinking supercooled plumes from sea‐ice formation, which may be important for cooling the deep ocean and transporting constituents such as carbon, nutrients, or oxygen from the ocean's surface to deeper layers.

A recent Science Highlight from the Ocean Carbon and Biogeochemistry Program highlights the work of SOCCOM researchers Lionel Arteaga, Seth Bushinsky, and Jorge Sarmiento:


OCB Science Highlight
July 8, 2020

The Southern Ocean is a major player in driving global distributions of heat, carbon dioxide, and nutrients, making it key to ocean chemistry and the earth’s climate system. In the ocean, biological production and export of organic carbon are commonly linked to places with high nutrient availability. A recent paper, published in Global Biogeochemical Cycles, highlighting new observations from robotic profiling floats demonstrates that areas of high carbon export in the Southern Ocean are actually associated with very low concentrations of iron, an important micronutrient for supporting phytoplankton growth. This suggests a decoupling between the production and export of organic carbon in this region.  [read more]
