Earlier this year, we conducted an online survey and consultation with the broader ocean science community to assess what we perceive as emerging skills gaps in basic physical chemistry training and expertise in several areas of chemical oceanography, especially (but not exclusively) including the ocean carbonate system. In the survey, we asked just for this information:
We received well over 100 responses, with very many insightful observations and answers to our questions. We invite you to read the brief summary report describing the skill gap survey results and associated community feedback on recommended paths forward. Read the report.
Join us for a virtual community discussion at OA Week in November
To follow up on this survey, we are convening an online community discussion on Tuesday 19 November at 1600-1730 GMT/1100-1230 ET as part of the Global Ocean Acidification Observing Network (GOA-ON)’s Ocean Acidification (OA) Week 2024. The purpose of this discussion will be to discuss next steps for a community activity (most likely a workshop), including its focus, content, participants, and outcomes to help address the emerging skills gap identified in the survey. Register to participate in this community discussion HERE. If you would like further information, or you represent an organization that would like to participate in this effort, please get in touch with either Heather Benway (hbenway@whoi.edu) or Simon Clegg (s.clegg@uea.ac.uk).

One of the longest running open ocean time-series on our planet, the Hawaii Ocean Time-series (HOT) can now be accessed using webODV at https://hot.webodv.awi.de.
webODV [Mieruch and Schlitzer, 2023]) is the online version of the Ocean Data View (ODV) software. It is developed at the Alfred Wegener Institute, Bremerhaven, Germany with the aim to provide clients with user-friendly interfaces in their web-browser and access datasets that are centrally maintained and administered on a server using the full capacity of ODV.
This platform has recently been adapted to serve physical, biochemical, and ecological data from the HOT program. Dr. Sebastian Mieruch has generated an automated processing chain to aggregate, harmonize, and convert HOT data to the ODV format. Video tutorials for use of webODV to access, plot, and download HOT data can be found at https://hot.webodv.awi.de/docs.

BGC Argo Webinar #8: Comparing BGC-Argo observations with models
October 16, 2024, 11am Pacific/2pm Eastern
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 comparisons between BGC-Argo observations and ocean model simulations focusing on bbp and particulate forms of carbon. 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&A session. Recordings will be available on the OCB and GO-BGC websites.

2) Camila Serra-Pompei (Technical University of Denmark): Assessing the potential of backscattering as a proxy for phytoplankton carbon biomass
The particulate backscattering coefficient (bbp) has often been used as an optical proxy to estimate phytoplankton carbon biomass (Cphy). However, total observed bbp is impacted by phytoplankton size, cell composition, and non-algal particles. The scarcity of phytoplankton carbon field data has prevented the quantification of uncertainties driven by these factors. Here, we first review and discuss existing bbp algorithms by applying them to bbp data from the BGC-Argo array in surface waters (<10m) and show that errors can be large when the bbp signal is low. Next, we use a global ocean circulation model (the MITgcm Biogeochemical and Optical model) that simulates plankton dynamics and associated inherent optical properties to quantify and understand uncertainties from bbp-based algorithms in surface waters. In an ideal world where field data has no methodological uncertainties, the model shows that bbp algorithms could estimate phytoplankton carbon biomass with an absolute error close to 20% in most regions.
3) Martí Galí Tàpias (Institute of Marine Sciences [ICM-CSIC], Spain): Constraining stocks and fluxes of Particulate Organic Carbon (POC) through the comparison between particulate backscattering measurements and the PISCESv2 model
BGC-Argo data offers a great opportunity for model evaluation, optimization, and the development of improved parameterizations, ultimately furthering our mechanistic understanding. However, comparison between BGC-Argo observations and models requires careful consideration of the spatiotemporal scales that each of them can resolve. When using particulate backscattering (bbp) as a proxy for particulate organic carbon (POC), additional attention must be paid to the variability in the POC/bbp ratio, its uncertainty, and its underpinning biogeochemical drivers. In this talk I will present comparisons between bbp from BGC-Argo and simulated POC based on both 3D (Eulerian) and 1D (pseudo-Lagrangian) frameworks. I will discuss the potential and limitations of model parameter optimization using BGC-Argo bbp as the observational reference. Finally, I will explore the impacts of optimized model parameters on mesopelagic POC budgets and vertical fluxes in the PISCESv2 model.

OCB Scoping Workshop Leaky Deltas: Sources or sinks in the global carbon cycle?
March 17-20, 2025 at Louisiana State Univ. (Baton Rouge, LA)
River deltas and the adjacent coastal ocean are critical interfaces between terrestrial and oceanic environments. Deltas are the entry point of ~50% of the fresh water and 40% of all global particulate matter entering the ocean. They are major centers for particulate and dissolved organic carbon transfer between (i.e., to and from) land to ocean.
Recent evidence suggests that coastal oceans have become net sinks for atmospheric CO2 during post-industrial times and continued human pressures in coastal zones. Alterations to deltas will likely have an important impact on the future evolution of the coastal ocean’s carbon budget.
NOTE This workshop has multiple deadline options: early (if you need a visa to attend), mid (if you want to apply for travel support), and a final deadline for all applications.
