2022 OCB Activity Solicitation

2022 OCB Activity Solicitation The Ocean Carbon and Biogeochemistry (OCB) Program is soliciting proposals for OCB activities that will take place or begin during the 2022 calendar year. Due to ongoing COVID-related uncertainties, in-person activities should include contingency plans in case delays or cancellations are necessary. We seek proposals for OCB-relevant workshops and activities as […]

How atmospheric and oceanographic forcing impact the carbon sequestration in an ultra-oligotrophic marine system

Sinking particles are a critical conduit for the export of material from the surface to the deep ocean. Despite their importance in oceanic carbon cycling, little is known about the composition and seasonal variability of sinking particles which reach abyssal depths. Oligotrophic waters cover ~75% of the ocean surface and contribute over 30% of the […]

New Technical Manual “Standards and practices for reporting plankton and other particle observations from images

The OCB Phytoplankton Taxonomy Working Group has been working to establish standards and best practices for submitting taxonomic and morphological information for plankton and other particles from images collected by imaging instruments, such as the Imaging FlowCytobot (IFCB), FlowCAM and Underwater Vision Profiler (UVP), to data repositories (e.g., NASA’s SeaWiFS Bio-optical Archive and Storage System (SeaBASS) and […]

US BioGeoSCAPES Planning Workshop November 10-12

Dear Colleagues, The US BioGeoSCAPES Planning Workshop, funded by the US Ocean Carbon & Biogeochemistry (OCB) program will take place November 2021 (rescheduled). The proposed BioGeoSCAPES program aims to improve our understanding of the functioning and regulation of ocean metabolism and its interactions with nutrient cycling, within the context of a hierarchical seascape perspective. This […]

A new proxy for ocean iron bioavailability

In many oceanic regions, iron exerts strong control on phytoplankton growth, ecosystem structure and carbon cycling. Yet, iron bioavailability and uptake rates by phytoplankton in the ocean are poorly constrained. Recently, Shaked et al. (2020) (see GEOTRACES highlight), established a new approach for quantifying the availability of dissolved Fe (dFe) in natural seawater based on […]
