Gulf of Mexico coastal carbon workshop MARCH 2013

Page history last edited by Heather Benway 9 years ago

Gulf of Mexico regional team meeting - March 27-28, 2013 (St. Petersburg, FL) 


Lead Coordinators: Paula Coble (pcoble@mail.usf.edu), Heather Benway (hbenway@whoi.edu)




Coastal boundary: 50-m isobath


River plume: 28-PSU salinity cutoff (the location of this cutoff varies by season) - get plume area and plume area monthly climatology (courtesy of R. Hetland)


Draft Flux Chapters: See status below. Please contact Heather Benway to obtain flux chapter drafts

  • Air-sea exchange - first draft complete, edits underway
  • Primary productivity - first draft complete, edits underway
  • Fluxes in estuaries -  first draft complete, edits underway
  • Submarine groundwater discharge - first draft complete, edits underway
  • Cross-shelf flux - first draft complete, edits underway
  • Respiration and NCP - first draft in progress (contact: Gary Hitchcock)
  • Riverine fluxes - first draft in progress (contact: Beth Boyer)




The agenda with links to the presentations is listed below. The participant list is available here.
