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.
#argofloats #oneargo
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.

🌊BGC-Argo float of the month is a sensor, not a float. Bif and Johnson (GBC; doi/10.1029/2024GB008473) show that the concentration of nitrite can be extracted from the UV spectra of ISUS or SUNA nitrate sensors.

But more..

Time series of a BGC‐Argo float WMO#5906483 deployed in the ETNP in January 2022 (see inset map reference). (a) Mean monthly POC stocks at the upper 100 m depth. (b) Chlorophyll fluorescence concentrations at the upper 200 m depth. Dashed black lines denote the ML. (c) POC concentrations overlain by the ML. (d) Nitrate concentrations. (e) Nitrite concentrations. (f) Thiosulfate concentrations. (g) Oxygen concentrations minus a background correction from the sensor calibration offset. Continuous black lines denote the isolines where corrected O2 = 1 μmol kg^-1

Last week in Hobart, 56 participants met to discuss leveraging hyperspectral PACE satellite data for the Southern Ocean. Talks ranged from photophysiology to satellites, with @thenasaearth.bsky.social keynote Dr. Julia Uitz highlighting links to BGC-Argo and large-scale biogeochemical processes.

A new paper, led by GO-BGC researcher @koelling.bsky.social, using @bgc-argo.bsky.social data, examines ocean ventilation in the subpolar North Atlantic. These insights enhance our understanding of how oxygen enters the deep ocean and may aid in predicting future oxygen loss due to climate change.

Our new 🌊 paper “Progressive oxygenation of the North Atlantic Subpolar Gyre” is out @jgroceans.bsky.social (open access): agupubs.onlinelibrary.wiley.com/doi/10.1029/...

We examined the breathing of one of the ocean’s lungs 🩺 and found some surprises

Which is where our study comes in - improving our understanding of how the North Atlantic is ventilated currently

To find out, we used GOBAI-O2, a data product created by @jdsharp.bsky.social with the help of an army of ocean robots that sample all over the world (@bgc-argo.bsky.social)

🌊A busy day for @mbarinews.bsky.social science and @globaloceanbgc.bsky.social, the major US contribution to @bgc-argo.bsky.social.

BGC-Argo floats used to study marine heatwaves and oxygen deficient zones. Great work by Mariana Bif - University of Miami, former MBARI postdoc.

🌊 The first BGC-Argo float of #ITINERIS has been deployed by Monaco Explorations in the Mediterranean!

It will deliver years of essential ocean physics & biogeochemistry data.

👏 Congrats to the whole team!
