Please join the kick off of the four-part Pathways Connecting Climate Changes to the Deep Ocean Webinar Series on Thursday, April 11, at 1 pm ET! This webinar series will set the stage for the Pathways Connecting Climate Changes to the Deep Ocean Workshop and ignite preliminary conversations between observational oceanographers and modelers across physical, biogeochemical, and ecological communities. Through this webinar series and the workshop, we aim to develop recommendations for improved detection and attribution of change in the global deep ocean system. This webinar series will also include presentations on April 18, May 2, and May 9. Read more about the presentations and add the events to your calendar.

Please join us for the quarterly GO-BGC webinar, hosted by the US Ocean Carbon and Biogeochemistry Project Office. This webinar will be focused on high-latitude ocean biogeochemistry by exploring the research of two groups that participated in the 2023 GO-BGC/BGC Argo Float Data Workshop at the University of Massachusetts Boston. The webinar will begin with an update on the status of the GO-BGC float array, followed by two short presentations. We’ll then close with a community discussion and Q and A session. Recordings will be available on the OCB and GO-BGC websites.
Agenda for May 9, 10 AM Pacific / 1 PM Eastern:
An update on the GO-BGC program
Biogeochemical properties of the Lofoten Basin Eddy from 14 years of BGC-Argo float data
Oceanic eddies are typically short lived but are a crucial physical phenomenon supporting heat and nutrient exchanges across water bodies. The Lofoten Basin Eddy (LBE) is a seemingly permanent topographically constrained anti-cyclonic eddy situated in the northern Norwegian Sea containing relatively cool surface waters and consistently warmer subsurface waters. As such, the conditions in the LBE may drive significantly different biogeochemical processes than the surrounding waters. Here we examine the unique biogeochemical signatures of the LBE with the 14-year timeseries of BGC-Argo float observations. We describe methodology for float-eddy colocation and examine differences in key biogeochemical parameters inside and outside of the eddy, including organic carbon export.
Lessons and opportunities from the Southern Ocean Sea Ice team at the 2023 GO-BGC Float Data Workshop
In the winter of 2023, the Southern Ocean reached a record low sea ice extent anomaly. This unprecedented low sea ice coverage coincided with the August convening of the GO-BGC float data workshop. What insights could a cohort of motivated researchers uncover with two working days and the BGC Argo dataset? In this talk, we present preliminary data from BGC floats deployed in the Southern Ocean marginal sea ice zone. We illustrate the potential of the observational network to investigate further questions about the dynamics and impacts of changing sea ice. Finally, we highlight insights and challenges from the GO-BGC workshop to demonstrate the further potential of collaborative data working groups.
This year’s OCB2024 swag will be inspired by YOU! Submit a drawing/design for an OCB t-shirt to ocb_news@whoi.edu by April 22, 2024 (Earth Day!) and we’ll have an open community vote to select the winning design. The top design will be printed on t-shirts available at OCB2024. The designs should reflect the scientific and community building aims of OCB and need not reflect OCB2024 themes. Anyone who submits a design will receive a free t-shirt, even if they can’t attend OCB2024 in person.
OCB2024 is June 10-13, 2024 in Woods Hole, MA
Registration is open and plenary session descriptions are now available on the workshop website!
We present the first edition of a global database (CoastDOM v1) and a resulting data manuscript, which compiles previously published and unpublished measurements of DOC, DON, and DOP in coastal waters, consisting of 62,338 (DOC), 20,356 (DON), and 13,533 (DOP) data points, respectively.
CoastDOM v1 includes observations of concentrations from all continents between 1978 and 2022. However, most data were collected in the Northern Hemisphere, with a clear gap in DOM measurements from the Southern Hemisphere.
This dataset will be useful for identifying global spatial and temporal patterns in DOM and will help facilitate the reuse of DOC, DON, and DOP data in studies aimed at better characterizing local biogeochemical processes; closing nutrient budgets; estimating carbon, nitrogen, and phosphorous pools; and establishing a baseline for modelling future changes in coastal waters.
The aim is to publish an updated version of the database periodically to determine global trends of DOM levels in coastal waters, and so if you have DOM data lying around, please submit it to Christian Lønborg (c.lonborg@ecos.au.dk).

There is currently considerable interest in margin processes within the oceanographic community, particularly in the closely related areas of carbon, nitrogen and iron cycling. To bring multiple investigators together, we are convening a Town Hall at the OSM 2024 Meeting in New Orleans on Monday from 12:45 to 1:45 (220-222, Second Floor). Much of the rationale arose from conversations within the GEOTRACES community as well as the product of the Benthic Ecosystem and Carbon Synthesis (BECS) Working Group, which has been working under the auspices of OCB for over a year. The goal of the town meeting is to start a wider conversation about margin processes amongst geochemists, biologists, physical oceanographers and modelers to talk about common problems. We are particularly excited about convening a Town Hall at this meeting to engage international researchers. Many groups, especially in Europe and Japan, have well established margin processes and we are keen to learn from them. It would greatly assist us in planning and addressing issues people care about if you could RSVP (jmoffett@usc.edu) and fill out this questionnaire. We plan to present an overview but the setup is informal, in order to encourage discussion. If you have some ideas or slides you would like to contribute, please send them to us for inclusion – it would be much appreciated.
We have funds for lunch for the first 30 participants!
