The 3 graphs show temperature, salinity, and oxygen from the surface to 300 m versus year from 2018 through 2025 for profiling float 5905383. The map shows the trajectory of the float from deployment in the Weddell Gyre (green square) and a loop around the Weddell sea to the present position at the red square.

What's interesting as the Thanksgiving Holiday arrives? The first @bgc-argo.bsky.social profiling floats begin to emerge from under Antarctic sea ice each year. Float 5905383 is the first @soccomproject.bsky.social float for 2025/26. It has spent 7.9 years operating under ice.

Robotic Floats Quantify Sinking Carbon in the Southern Ocean - Eos An estimated 2.69 billion tons of carbon are exported to the deep sea every year from the Southern Ocean.

A crew of floating robots helped researchers estimate that 2.69 billion tons of carbon are exported to the deep ocean.

🌊🧪@bgc-argo.bsky.social Float of the Month. WMO 7900823 deployed nearly 80 south in the Ross Sea has done 2 years under ice. Here's the data plot (all data freely available @soccomproject.bsky.social). No bloom this year! Too much ice melt, no deep mixing, and no iron to feed plankton - IMO.

The GO-BGC and SOCCOM programs successfully deployed 115 BGC-Argo profiling floats in 2024.

Real-time data collected by these biogeochemical floats is helping scientists better understand, predict, and mitigate the impacts of climate change.
