New webinar series! Find out more 4D-BGC group website: https://4d-bgc.github.io

Past: Webinar #1 on November 26 at 0600 EST/1200 CET

Title: Advancements in Biogeophysical 4D reconstructions: New methods development and exploitation of existing products for scientific investigations

Presenter: Dr. Bruno Buongiorno Nardelli Italian National Research Council

This presentation will address two key topics: the development of physically-informed neural network methods for the joint reconstruction of physical and biological variables in the Mediterranean Sea, and the analysis of existing data-driven 4D reconstructions of POC, combined with advanced dynamical diagnostics, to uncover the interannual variability of organic carbon export in the global ocean. The first part will introduce the approach tested in the European Space Agency’s 4DMED-Sea project, while the second will focus on research conducted within the H2020 AtlantEco project.

Webinar Series Information: The 4D-BGC Working Group seeks to enhance access and utility of Biogeochemical (BGC) Argo observations through four-dimensional (4D) data products. These advanced data products aim to refine our understanding of ocean biogeochemistry, improve biogeochemical models and reanalysis products, and provide valuable insights for policy-making. The goal of this webinar series is to introduce new and in-development BGC data products, review techniques used to develop data products from in situ observations, and to explore ways in which 4D-BGC products are leveraged to answer scientific questions.

This event will highlight, in parallel, the quantitative aspects of Blue Carbon (e.g., their roles in NDCs) as well as the more qualitative aspects of Blue Carbon (e.g., cultural ecosystem services). Specifically, this event will address the ways in which blue carbon has been and can be further included in GG inventories and Nationally Determined Contributions (NDCs), through the 2025 NDC revision cycle. This event will highlight some of the tools the United States Government and Pacific partners have created to track and quantify blue carbon sinks, and to identify effective opportunities for conservation and restoration as well as emphasize the
intrinsic and cultural ecosystem services provided by blue carbon in the Pacific.

EXTENDED OCB Scientific Steering Committee Nominations by Friday, November 22!

We are seeking additional nominees with expertise in the following areas:

• Data science and its intersection with ocean and carbon cycle science
• Large scale inorganic carbon cycle – modeling, observations, etc.
• Paleo perspectives on ocean biogeochemical cycles and marine ecosystems
• Benthic processes – sediment biogeochemistry, diagenesis, ecology, etc.

The following SSC members are scheduled to rotate off at the end of 2024:

• Jeff Bowman (SIO) – microbial ecology, bioinformatics, coastal and high latitude ecosystems, modeling
• Susanne Craig (NASA GSFC) – satellite RS, bio-optics, machine learning techniques and ocean color algorithm development
• Tim DeVries (UCSB) – carbon cycle modeling (biological & solubility pumps), inverse modeling of ocean circulation and mixing, carbon sequestration/marine CDR
• Zachary Erickson (NOAA PMEL) – biophysical interactions
• Shaily Rahman (Univ Colorado, Boulder) – marine biogeochemistry and sedimentary processes

Please consider casting a diverse net in submitting nominations. We are seeking to entrain new voices and ideas in OCB! Nominees should be at US-based institutions (including Univ. Puerto Rico, Univ. Virgin Islands or in other US territories, minority-serving institutions, including historically Black colleges and universities, Hispanic-serving institutions, tribal colleges and universities, etc.). Please submit your nomination (self-nominations are welcome) here. 

Nominees are evaluated using a rubric that includes consideration of geography (balance across the SSC), science expertise, career stage and other diversity and equity measures. We encourage re-nomination if a prior nomination round was not successful. Many SSC members are nominated multiple times before becoming members! OCB SSC members serve a 3-year term. For more information on the OCB SSC, including a list of current and previous SSC members, the SSC charge and terms of reference, and links to the past year of SSC minutes, please visit the SSC page of the OCB website. To learn more about what the OCB SSC is/does, please visit the SSC page of the OCB website and feel free to reach out to current SSC members about time commitment and their experiences as SSC members.
