Scientific Steering Committee

The Ocean Carbon and Biogeochemistry Scientific Steering Committee (OCB SSC) was formed in February 2006. The OCB SSC was created jointly by NSF, NASA and NOAA to provide critical leadership to the OCB community by helping to identify research priorities and promote, plan, and coordinate collaborative, multidisciplinary research opportunities in ocean biogeochemistry. SSC members serve a term of three years. Parentheses indicate term end (end of calendar year) for each member.

Randelle Bundy (UW) (2027) (Vice Chair) - cycling of bioactive trace metals, chemical speciation of iron, copper, nickel and cobalt, impacts on microbial community structure in the ocean, connecting trace metals with productivity and the carbon cycle

Dreux Chappell (USF) (2025) (Chair)- molecular microbial ecology, phytoplankton cultivation/physiology, and trace metal biogeochemistry

Anela Choy (Scripps Inst. Oceanography) (2025) - Deep-sea biological oceanography, water column food web ecology, pelagic ecosystem dynamics, biochemical tracers

Jason Graff (Oregon State Univ.) (2027) Biooptics, satellite remote sensing

Bror Jönsson (Univ. New Hampshire) (2027) - land-open ocean continuum processes, coastal acidification, biophysical interactions, phytoplankton dynamics, air-sea exchange, data analysis, remote sensing and algorithm development

Kristen Krumhardt (NCAR) (2026) - marine biological, ocean ecosystem modeling, Southern Ocean ecosystem dynamics

Jonathan Lauderdale (Massachusetts Inst. of Technology) (2027) -  biogeochemical modeling, paleoclimate, physical oceanography, high latitude processes occurring in high latitude regions such as the Southern Ocean.

Jessica Luo (NOAA/GFDL) (2025) - plankton ecology, food webs, biogeochemical dynamics, global-scale marine ecosystem models

Kanchan Maiti (Louisiana State Univ.) (2026) - biogeochemical cycling along aquatic continuum, deep ocean and benthic fluxes, geochemical tracers, autonomous observation platforms

Melissa Meléndez (early career) (Univ. Hawai'i) (2026) - marine carbonate chemistry, ocean acidification, net ecosystem metabolism, marine carbon dioxide removal

Sarah Mincks (Univ. Alaska Fairbanks) (2027) benthic-pelagic coupling, marine organism-mediated carbon cycling

David “Roo” Nicholson (Woods Hole Oceanographic Inst.) (2025) - global biogeochemical cycles in the context of a changing climate, cycling of dissolved gases, including oxygen, carbon dioxide, methane and the noble gases
