The 2013 OCB Summer Science Workshop was held July 22-25, 2013 at the Woods Hole Oceanographic Institution Quissett Campus, Clark 507,  in Woods Hole, MA.

Each of this year’s plenary sessions began with an overview talk to provide background and broader context for an interdisciplinary audience, followed by a series of more focused research talks to highlight recent scientific progress. The session descriptions and confirmed speakers are listed below. For more information, view the agenda. As usual, the meeting began bright and early the morning of Monday, July 22 ended at lunch time on Thursday July 25.

Coping With Your Data: WHOI Data Solutions and Resources Workshop
Friday, July 26, 2013, also at WHOI (Clark 507)
The workshop will be a forum to discuss the data management needs of WHOI scientists.
We'll showcase tools that have been developed by some current researcher/informaticist collaborations. NSF Program Manager Dave Garrison has confirmed that he will be attending. We are awaiting responses from several other program offices. Click here for more information. 

Workshop Highlights

Narrowing in on key biological carbon fluxes: Estimates, approaches, and uncertainties
Chairs: Ricardo Letelier, Craig Carlson

This session will focus on producing best estimates of critical carbon fluxes (e.g., net community production, or NCP) derived from measurements made via satellite, autonomous platforms, and shipboard biogeochemical time-series. Speakers in the session will discuss statistical estimates of flux uncertainties and discrepancies in methods, underlying sources of variability such as sampling and analytical methods, physical transport, and different assumptions regarding the basic cycling of associated tracers (e.g., gas exchange rates). Confirmed speakers for this session include Ken Johnson (MBARI), Rachel Stanley (WHOI), Paul Quay (UW), Matt Church (U. Hawaii), and Dave Siegel (UCSB).

Evolutionary responses of plankton to climate change
Chairs: Tatiana Rynearson, David Hutchins
Climate change is expected to alter many aspects of the planktonic environment.  This session will examine the potential of marine plankton to evolve in response to these changes and explore how evolutionary changes may influence community structure and biogeochemical cycling.  Presentations will include perspectives on the evolutionary potential and responses of cyanobacteria, protists and metazoans to climate change.  Confirmed speakers for this session include Tatiana Rynearson (URI), Carol Lee (Univ. of Wisconsin), Sinead Collins (Univ. of Edinburgh), Elena Litchman (Michigan State Univ.) and Dave Hutchins (Univ. of Southern California).

Trace element-biota interactions
Chair: Mak Saito

In addition to major elements such as carbon, nitrogen, phosphorus, and silicon, the productivity and species composition of marine phytoplankton communities are strongly influenced by trace metals such as iron, zinc, cobalt, manganese, copper, and cadmium. Conversely, phytoplankton directly affect the distribution, speciation, and bioavailability of these metals. The GEOTRACES Program has provided tremendous insight into the distribution, sources, and sinks of trace metals in the ocean. This session will focus on interactions between trace metal nutrients and phytoplankton in the ocean, including the roles of key micronutrients in various biological functions. Confirmed speakers for this session include Mark Moore (Southampton), Kathy Barbeau (SIO), Seth John (USC), Mak Saito (WHOI), and Adrian Marchetti (UNC). 

Southern Ocean processes
Chairs: Jorge Sarmiento, Kendra Daly

The Southern Ocean undergoes natural fluctuations in biogeochemical cycling over a wide range of spatiotemporal scales, and is also responding in measurable ways to the atmospheric increase in CO2 and the ozone hole, but the associated mechanisms of response are poorly quantified. Major changes are also occurring in Southern Ocean food webs, which have direct effects on key species and indirect impacts throughout the food web, and the consequences of these for carbon and biogeochemical cycling and biological production are unknown. This session will focus on the challenges that we face in our understanding of Southern Ocean physical, biogeochemical, and ecosystem processes in response to current and future climate.  Confirmed speakers for this session include Mike Meredith (BAS), Nicole Lovenduski (Univ. Colorado), Kevin Arrigo (Stanford Univ.), Eileen Hofmann (ODU), and Hugh Ducklow (LDEO).
