BGC-Argo Webinar Series!

BGC Argo Webinar #4, February 15

Observing Mesoscale and Sub-Mesoscale Processes with BGC Argo

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 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 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 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 for February 15, 10 AM Pacific / 1 PM Eastern

October 5 BGC-Argo Webinar #3: Using BGC-Argo Measurements to Study the Effects of Weather and Extreme Events

Please join us for the quarterly GO-BGC webinar, hosted by the US Ocean Carbon and Biogeochemistry Project Office. This webinar will be 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 will open with an update on the status of the GO-BGC float array, then we will hear 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. Recordings will be available on the OCB or GO-BGC website.

Agenda for October 5, 1 PM Pacific / 4 PM Eastern

Yui Takeshita (Monterey Bay Aquarium Research Institute, USA): An update on the 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): Topic: The role of storms on air-sea CO2 flux in the Southern Ocean

Discussion

GO-BGC Science Webinar 2: Understanding ecological dynamics using BGC-Argo data
June 29, 2022 (1-2.30pm ET)

This quarterly GO-BGC webinar, hosted by the US Ocean Carbon and Biogeochemistry program 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 three short 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.

  • 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 webinar of this series was held on March 30th, 10-11 am Pacific/1-2 pm Eastern. It will covered the current status of BGC floats worldwide, projected float deployment locations, and tools that we have developed to streamline data access, followed by community discussion and Q&A.

  • Introduction to the GO-BGC webinar series (Yui Takeshita, MBARI)
  • Introduction to BGC-Argo and GO-BGC (Alison Gray, University of Washington)
  • Upcoming float deployment plans (Yui Takeshita, MBARI)
  • How to use BGC-Argo data? (Jonathan Sharp and Hartmut Frenzel, NOAA PMEL)
  • What is the quality of BGC-Argo data? (Yui Takeshita, MBARI)
  • Discussion and community Q&A

GO-BGC Webinar Series Overview
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 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.

Webinars will be hosted roughly quarterly. Subsequent webinars will focus on scientific or geographic themes. We will highlight emerging research results based on BGC-Argo data, and aim to promote early career researchers. All webinars will be recorded and made available through the OCB and GO-BGC websites.
