SOCCOM News

SOCCOM scientists will be deploying 6 biogeochemical profiling floats from US GO-SHIP cruise P6 on the R/V N.B. Palmer leaving Sydney, Australia on July 3. The cruise will cross the Pacific at about 32 deg S. This is the fourth 5-10 year repeat of this section (1993, 2003, 2009, and now)  - in addition to deploying the SOCCOM floats, plans are to occupy >270 stations from top-to-bottom with all GO-SHIP parameters and deploy 38 profiling floats for Argo, including 2 Deep Solo floats.

SOCCOM scientist Isa Rosso is co-chief scientist for Leg 1 of the cruise from Sydney to Papeete, Tahiti.  Also on P06 is SOCCOM graduate student Rebecca Beadling from the University of Arizona, a modeler at sea for the first time. You can follow Isa via the P06 cruise blog and Rebecca on her blog "From the Desert to the Sea."

DynOPO Cruise 2017 is the blog of Steve Griffies, a SOCCOM collaborator at NOAA’s Geophysical Fluid Dynamics Laboratory. A theorist and computer modeler, Steve is taking part in his first research cruise to experience the Southern Ocean firsthand.

A University of Washington oceanographer is chief scientist on a voyage in the waters around Antarctica as part of a major effort to monitor the Southern Ocean.

Stephen Riser, a UW professor of oceanography, embarked Dec. 24 as part of the Southern Ocean Carbon and Climate Observations and Modeling, or SOCCOM, project to collect better data about the planet’s most remote ocean.

The Southern Ocean State Estimate (SOSE) is a general circulation model that is least squares fit to all available observations to produce a physically realistic estimate of the ocean’s state. As part of SOCCOM, a version of SOSE has been developed that incorporates biogeochemistry (B-SOSE).  Solutions are available at http://sose.ucsd.edu.

B-SOSE includes the BLING biogeochemical model which represents carbon, nitrogen and oxygen cycles, and constrains this output with biogeochemical data from Argo floats, hydrographic cruises, and satellites. Extensive validation of the solution is available at at http://sose.ucsd.edu/bsose_valid.html, and the SOSE team is happy to provide any additional diagnostics upon request.

Moving forward, the team will be focusing on a 2013-2020 “SOCCOM era” B-SOSE with assimilation of SOCCOM float data. For more information contact Matt Mazloff (mmazloff@ucsd.edu) or Ariane Verdy (averdy@ucsd.edu).
