A National Science Foundation Mid-Scale Research Infrastructure Project


The Global Ocean Biogeochemistry Array is a global robotic network of profiling floats carrying chemical and biological sensors that will revolutionize our understanding of ocean biogeochemical cycles, carbon uptake, acidification, deoxygenation, and ecosystem health.

GO-BGC-affiliated students become PhDs

Dr. Paul Chamberlain recently defended his PhD thesis "Semi-Lagrangian Float Motion and Observing System Design" at the Scripps Institution of Oceanography (SIO).  Paul has studied and predicted where floats will go when they are underwater and the best locations to...

GO-BGC celebrates its first anniversary

Locations of GO-BGC floats deployed to date in the Atlantic and Pacific oceans. By 2025, the GO-BGC array will cover all the world’s major ocean basins. (MBARI) The NSF-funded Global Ocean Biogeochemistry Array (GO-BGC Array) is one year old!  On March 25, 2021, a...

Beware the Blob! Ocean heatwaves threaten microbes that help counter global warming

Mariana Bif, a Research Specialist at MBARI, was recently interviewed in article in the Bulletin of the Atomic Scientists entitled: Beware the Blob! Ocean heatwaves threaten microbes that help counter global warming.  Mariana talks about using data from biogeochemical floats to look at anomalous amounts of organic carbon in the ocean during blob years and outlines the connection with climate change.

Next week the #OneArgo Data Management Team meets 👉: https://cpaess.ucar.edu/meetings/admt-23-argo-data-management
An opportunity for @bgc_argo to provide an annual review: 184 floats deployed by 13 nations 🇺🇸🇨🇦🇫🇷🇬🇧🇮🇹🇩🇪🇦🇺🇿🇦🇮🇳🇨🇳🇯🇵🇧🇷🇪🇺! A great achievement that brings us one step closer to the target of 250 floats.

The team on the R/V Nathaniel B. Palmer has deployed 3 floats in the Drake passage. They had a stop at Palmer Station in Antarctica and now they are underway again, continuing their work in the Southern Ocean. Follow along on the @GO_BGC blog:

As part of the GO-BGC outreach efforts, the MATE ROV Competition Float Challenge invites students to see what it’s like to be an ocean engineer! Inspired by the GO-BGC and Southern Ocean Carbon and Climate Observations and Modeling - SOCCOM robotic floats, teams of students are tasked with building a float that can descend to depth and back to the surface. As they learn and creatively apply science, technology, engineering, and math (STEM) to solve real-world problems, they strengthen their critical thinking, collaboration, entrepreneurship, and innovation. We’re excited to see what the next generation of STEM leaders creates! ... See MoreSee Less
