Ocean Carbon & Biogeochemistry (OCB) Related Programs is a grant from National Science Foundation (NSF) - Division of Ocean Sciences that funds research on marine ecosystems, biogeochemical cycles, and the ocean's role in the global carbon cycle.

The program supports working groups, workshops, and scientific activities covering topics including estuarine and coastal carbon fluxes, ocean-atmosphere interactions, and changing marine ecosystems. Eligibility generally extends to academic institutions and researchers. Funding amounts and specific deadlines vary by program; prospective applicants should contact an OCB program officer directly.

Ocean Carbon Uptake and Storage Estuarine and Coastal Carbon Fluxes Changing Marine Ecosystems Recent Science Highlights A small pH bias can make Southern Ocean CO₂ uptake look too weak The Southern Ocean is one of the most important regions for absorbing anthropogenic CO₂, and it is one of the most challenging places to observe, until Biogeochemical (BGC) Argo floats began to monitor this remote region year-round.

Yet, CO₂ uptake estimates based on float data have suggested a much weaker uptake Southern Ocean than estimates […] What happens when marine snow and oil mix? The Deepwater Horizon oil spill (April-July 2010) in the NE Gulf of Mexico provided researchers with an opportunity to explore what happens when marine snow and oil mix.

Marine snow are detrital particles or aggregates consisting of inorganic and organic components, such as bacteria, phytoplankton cells, zooplankton fecal pellets, and mucous feeding webs, and are […] El Niño-driven changes in the tropical Pacific O2 content and structure What drives the year-to-year variability of dissolved oxygen (O2) in the tropical Pacific?

A recent study explored this question using a global high-resolution model with active ocean biogeochemistry along with a machine learning based estimate of dissolved oxygen from Argo floats. El Niño and La Niña events play a major role in regulating the O2 […] When plastics slip into the carbon cycle What if a tiny amount of plastic could make the ocean’s carbon appear thousands of years older than it really is?

For decades, oceanographers have relied on routine measurements of particulate organic carbon to understand how carbon moves through the ocean, how long it persists, and how it shapes Earth’s climate.

These measurements, based on […] Improving our view of particle attenuation in the Southern Ocean with BGC-Argo floats How much organic carbon is actually transported to depth in the Southern Ocean and what are the mechanisms driving seasonal and regional variability?

With large-scale remote sensing observations constrained to the surface and the depth-resolved ship-based measurements being scarce, the emergence of the BGC-Argo fleet has opened up a new avenue to explore how carbon […] New unified interface for existing ocean carbonate chemistry data products The paper provides a comprehensive synthesis of 68 existing ocean carbonate chemistry data products and data product sets, including cruise-based compilations, time-series datasets, gap-filled observational products, and model-based reconstructions.

The authors highlight the diversity of available products, noting differences in spatial coverage, temporal resolution, methodologies, and intended scientific applications.
