Virtual Workshop on the New Global Ocean Biogeochemistry (GO-BGC) Array

Building a Community of Biogeochemistry Float Data Users

The Global Ocean Biogeochemistry (GO-BGC) array is a 5-year effort funded by the US National Science Foundation to produce and deploy 500 profiling floats equipped with biogeochemical sensors in the world ocean.  Deployments will begin in the first quarter of 2021. To inform and engage a broad oceanographic user community, the Ocean Carbon & Biogeochemistry (OCB) and the US Climate Variability and Predictability (CLIVAR) Programs are working with GO-BGC leadership to plan a virtual GO-BGC Scientific Workshop from June 28-30, 2021. The objectives of the workshop are to:

  • Introduce the GO-BGC plan to the global scientific community
  • Discuss and innovate on scientific applications of GO-BGC data
  • Provide background information on the flow of data and archiving
  • Deliver hands-on tutorials and computer code for accessing GO-BGC data

Presentations and discussions will be scheduled for 3-4 hours on each day.  Some pre-recorded presentations will be available online prior to each day’s events, so that participants can consider discussion items before the meeting. The organizers look forward to a large online participation in the meeting as this new, multi-year program gets underway.
