Welcome to the GO-BGC Webinar Series!
Hundreds of Biogeochemical (BGC) profiling floats have been deployed worldwide, and the number of floats is expected to continue to increase in the coming years. Specifically, the Global Ocean Biogeochemistry Array (GO-BGC) is a NSF Mid-Scale Research Infrastructure project that is funded to deploy 500 BGC floats globally over the next 5 years. We expect additional significant contributions from other US and international institutions, which will build towards a sustained global array of BGC-Argo floats.
The quality-controlled, freely available data from these floats are transforming our capacity to observe, quantify, and understand ocean biogeochemical processes and how they are responding to anthropogenic pressures (e.g., acidification and deoxygenation). With improved constraints on the biological carbon pump and air-sea CO2 exchange, these data sets will also inform marine ecosystem management and decision making.
This quarterly webinar series, hosted by GO-BGC and the OCB Project Office, aims to build and support a growing community of biogeochemical float data users. As the BGC-Argo array matures and expands its global coverage, so will the potential for scientific discovery. We hope that the applications and research findings highlighted in this webinar series will demonstrate the potential for these globally distributed datasets and inspire the community to explore novel applications, scientific questions, and new collaborations in the use of BGC-Argo data.

|Webinar Title & Link||Date||Speakers & Topics||Description|
|New tools for BGC-Argo data access and visualization|
|June 20, 2023||Yui Takeshita: Updates on GO-BGC (10 min)|
Reiner Schlitzer: Online analysis and visualization of BGC-Argo data with webODV (20 min)
Hartmut Frenzel: OneArgo toolbox for accessing and analyzing Argo data - overview and new features (20 min)
Q&A: 10 minutes
|This webinar will have 2 presentations on new tools for BGC-Argo data access and visualization. Dr. Reiner Schlitzer will present on webODV, a new online tool based on Ocean Data View that can be used to visualize, explore, and export BGC-Argo data through a GUI interface. Dr. Hartmut Frenzel will present on the One-Argo toolbox, an open source toolbox designed to efficiently access, process, and visualize BGC, Core, and Deep Argo data. Float data can be searched using a variety of criteria including sensor type, location, and date. Recordings will be available on the OCB and GO-BGC website.|

Discussion and community Q&A
|GO-BGC will host quarterly webinars about emerging science using GO-BGC or BGC-Argo float data, focusing on early career researchers. The webinar series is hosted by the US Ocean Carbon and Biogeochemistry program. The kickoff webinar is focused on updating the status of GO-BGC and BGC-Argo, projected float deployment locations over the next year, followed by community Q&A.|
