GO-BGC + OCB Webinar Series

This quarterly GO-BGC webinar, hosted by the US Ocean Carbon and Biogeochemistry Project Office, 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 began with an update on the status of the GO-BGC float array, followed by two short presentations, and a community discussion.

Webinar agenda:

• • Yui Takeshita (MBARI, USA):  An update on the GO-BGC program,.
  • Daniel Koestner (University of Bergen, Norway): Biogeochemical properties of the Lofoten Basin Eddy from 14 years of BGC-Argo float data, .
  • Sophie Shapiro (University of California San Diego, USA): Lessons and opportunities from the Southern Ocean Sea Ice team at the 2023 GO-BGC Float Data Workshop.
  • Discussion

This quarterly GO-BGC/BGC-Argo Webinar, hosted by the US Ocean Carbon and Biogeochemistry program focused on carbon export dynamics beginning with an update on the status of the GO-BGC float array, followed by two short presentations highlighting the Biogeochemical Argo array.  The webinar closed with a community discussion about recommended practices, challenges, and future perspectives of using BGC-Argo measurements to enhance our understanding of carbon export dynamics.

Webinar agenda:

• • Yui Takeshita (MBARI): Introduction and GO-BGC update.
  • Ellen Park (WHOI): Quantifying biological carbon pump parameters from the global Biogeochemical Argo float array.
  • Adam Stoer (Dalhousie University): Estimating marine phytoplankton biomass and productivity from Biogeochemical-Argo floats.
  • Discussion

This quarterly GO-BGC/BGC-Argo Webinar, hosted by the US Ocean Carbon and Biogeochemistry program had two presentations on new tools for BGC-Argo data access and visualization. Dr. Reiner Schlitzer  presented 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. Hartmut Frenzel presented 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.

Agenda:

• • Yui Takeshita (Monterey Bay Aquarium Research Institute): Updates on GO-BGC
  • Reiner Schlitzer (Alfred Wegener Institute for Polar and Marine Research): Online analysis and visualization of BGC-Argo data with webODV
  • Hartmut Frenzel (NOAA PMEL): OneArgo toolbox for accessing and analyzing Argo data – overview and new features
  • Discussion

This webinar, hosted by the US Ocean Carbon and Biogeochemistry Project Office, focused on using BGC-Argo float data to investigate chemical and biological processes in the ocean that are influenced by eddies, meanders, and other mesoscale and sub-mesoscale processes. The webinar began with an update on the status of the GO-BGC float array, followed by two short presentations, and a community discussion about recommended practices, challenges, and future perspectives of using BGC-Argo measurements to enhance our understanding of how mesoscale processes shape patterns of biogeochemistry in marine environments. Recordings will be available on the OCB and GO-BGC websites.

Agenda:

• • Yui Takeshita (Monterey Bay Aquarium Research Institute):  An update for GO-BGC program
  • Lily Dove (California Institute of Technology, USA): Investigating Ventilation at the Submesoscale in the Southern Ocean
  • Shuangling Chen (Second Institute of Oceanography, Ministry of Natural Resources, Hangzhou, China): Episodic oxygen injections observed from BGC-Argo
  • Discussion

The quarterly GO-BGC webinar, hosted by the US Ocean Carbon and Biogeochemistry Project Office, was the first of two consecutive webinars focused on using BGC-Argo float data to investigate chemical and biological processes in the ocean that are influenced by weather and extreme events. The webinar opened with an update on the status of the GO-BGC float array, then two short presentations about exciting new work in the main topic area. We’ll close with a community discussion about best practices, challenges, and future perspectives of using BGC-Argo measurements to enhance our understanding of how storms, heatwaves, and other ocean- and land-based extreme events shape patterns of biogeochemistry in the global ocean. 

Agenda:

• • Yui Takeshita (Monterey Bay Aquarium Research Institute, USA):  An update for GO-BGC program
  • Jakob Weis (Institute for Marine and Antarctic Studies, Australia): Using BGC-Argo floats to study phytoplankton blooms stimulated by the 2019-2020 Australian bushfires
  • Magdalena Carranza (Monterey Bay Aquarium Research Institute, USA): The role of storms on air-sea carbon exchange in the Southern Ocean.
  • Discussion

This quarterly GO-BGC webinar, hosted by US Ocean Carbon Biogeochemistry, focused on investigations of phytoplankton phenology and variability at regional to global scales using a range of chemical and bio-optical sensors on the BGC-Argo floats. We heard four presentations about exciting new work in this area, followed by a community discussion about best practices, challenges, and future perspectives of using BGC-Argo data to advance our understanding of ecological dynamics and the footprint of progressive climate change on the ocean.

Agenda:

• • Yui Takeshita (Monterey Bay Aquarium Research Institute):  An update for GO-BGC program
  • Nicholas Bock (Columbia University): Biogeographical classification of the global ocean from BGC-Argo Floats
  • Marin Cornec (NOAA Pacific Environmental Laboratory): Dynamics of the deep chlorophyll maxima at a global scale based on bio-optical measurements of BGC-Argo floats
  • Mariana Bif (Monterey Bay Aquarium Research Institute): The impact of heatwaves on the northeast Pacific ecosystem
  • Discussion

The first collaborative GO-BGC and US Ocean Carbon Biogeochemistry (OCB)-hosted webinar series presentation to familiarize and entrain data users on how to access and use GO-BGC and BGC Argo data. Hosted by Yui Takeshita (Monterey Bay Aquarium Research Institute), Alison Gray (University of Washington), Lynne Talley (University of California, San Diego), Mai Maheigan (OCB) and Heather Benway (OCB).
