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

And I thought we made a lot of @bgc-argo.bsky.social profiling floats!!!! We're going to have to work harder. @globaloceanbgc.bsky.social @soccomproject.bsky.social

🌊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.. @globaloceanbgc.bsky.social floats. @mbarinews.bsky.social

Using robots and AI to unlock the secrets of a remote ocean with @soccomproject.bsky.social 🌊🤖🌊 Applying machine learning algorithms to a trove of data collected by robotic floats has improved estimates of ocean productivity and carbon export in the Southern Ocean: www.mbari.org/news/new-ai-...

🌊The Southern Ocean is warming, is productivity changing? New paper by Liniger et al. uses the nitrate sensors on 274 SOCCOM/BGC-Argo floats to compute annual NCP. It has increased significantly over the past two decades. @mbarinews.bsky.social @soccomproject.bsky.social @bgc-argo.bsky.social‬

🌊 BGC-Argo float of the month. The 300th float of the GO-BGC project was launched in the S Atlantic. Funded by the US NSF, these floats provide essential observations of ocean metabolism - productivity, oxygen, pH... @bgc-argo.bsky.social‬ @globaloceanbgc.bsky.social #OneArgo #Argo

🌊Float of the Month. The BGC-Argo array in May 2025! With ships, it took decades to collect the data to visualize the chemistry and biology of the ocean interior. Now we can do it monthly, realtime, quality controlled. Access is easy with webODV. This is going to change things! #UNOC3 #OneArgo

🌊 As the #UNOC3 gets underway, the international community is calling for increased support for #OneArgo, a key phase of the #Argo program, which is essential for monitoring the ocean and addressing climate challenges. @cnrs.fr @euro-argo.eu www.ifremer.fr/en/espace-pr...

Welcome our newest addition to the fleet! ⛴️ We're excited to announce the arrival of our new flagship vessel, R/V David Packard, at our headquarters in Moss Landing, California. This state-of-the-art ship will expand our capacity for ocean exploration. Learn more: www.mbari.org/news/mbari-e...

So, speaking of Universities caving to government demands and people bringing up loyalty oaths, here's a story that involves a well known oceanographer. In 1935 Massachusetts enacted a law that required teachers in public and private schools to take a loyalty oath to teach in the state 1/n 🌊

🌊Float of the Month, 5906440 (@globaloceanbgc.bsky.social @bgc-argo.bsky.social). Drifting north for 4 years, it shows the evolution of the bio. response to ocean phys. At low latitudes, warm water does not mix deep enough (Mixed Layer Depth, black line on NO3 plot) to bring NO3 to the surface. 1/2

Protecting the ocean has always been a bipartisan effort, in Congress and across multiple White House administrations. In the face of ill-conceived attacks on @noaa.gov, it's time to raise our voices. My thoughts in defense of NOAA and #OceanScience: mbayaq.co/4k8vEsx

🌊MBARIs @mbarinews.bsky.social new research vessel, R/V David Packard, has left Vigo Spain to come home. Its first science mission, deploy @bgc-argo.bsky.social floats across the Atlantic and up the Pacific. First O2 float in for @argogermany.bsky.social. More for @globaloceanbgc.bsky.social

The demo is based on this video: www.youtube.com/watch?v=eZzp...

🌊🧪@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.

It’s 10 days into the new year & @globaloceanbgc.bsky.social & @soccomproject.bsky.social have already deployed 10 new @bgc-argo.bsky.social profiling floats. 410 in the water, 70 with chem & 332 have chem/bio sensors - O2, pH, NO3, & bio-optics. They sample the upper 2 km every 10 days. 🌊⛴️🌡🧪

Almost historical. I created the Periodic Table of Elements in the Ocean back in 1998 with my son, then age 14 who wrote the JavaScript, and daughter age 12 who chased down all references in the MLML library, to figure out how we could use the internet. Nice to see it in use. #mbari #globaloceanbgc

Happy Holidays from the SOCCOM (soccom.princeton.edu) and GO-BGC (go-bgc.org) projects. The present under the tree? 115 BGC-Argo profiling floats deployed this year and more at sea. All data freely available. Thanks to all the folks who made this happen and the US NSF for their support.

This is the first in an occasional series on ‘older ocean science papers you should read’. Ever wonder why cans no longer have Pb soldered seams? In 1980, Settle and Patterson used methods developed to measure Pb in seawater and measured lead in canned tuna. In Science (tinyurl.com/y4z83z8j), 1/4

Thank you Sonne. They are currently at sea on a Geotraces cruise in the Indian Ocean, Eric Achterberg Chief Sci. There are 7 GO-BGC (go-bgc.org) profiling floats on board and 3 already launched (7902123, -24, -25). We very much appreciate their help deploying floats.

🌊@BGC-Argo, @GO_BGC float of the month 4903026. This is the first BGC-Solo II float, developed @scrippsocean.bsky.social. Deployed off Monterey Bay, it has made 375 vertical profiles, most to 2000 m at 1 to 3 day intervals (>10 years at 10 d cycles). The upper 300 m of the record is shown.

🌊An awesome BGC-Argo paper in PNAS (doi.org/10.1073/pnas...) that does a global census of phytoplankton carbon. They conclude "Our study demonstrates that profiling robots enable more reliable monitoring of Earth’s phytoplankton, which is urgently needed to understand the impact of climate change."

🌊 Interested in ocean chlorophyll? A new paper by Long et al. rdcu.be/dXcjY explores the relationship between chloro, measured by BGC-Argo floats and by ocean color satellites. The figure shows seasonal maps of Chl_flt/Chl_sat. Systematic variations in the ratio are likely due to effects of Fe.

@davidho.bsky.social @GO_BGC Glad to contribute. I used to do a "profiling float of the month" on that other app. Here's my first for Bluesky. Float WMO_5905380 is nearing its 8th year operating under seasonal ice in the Weddell Sea and just popped up, transmitting data from last winter.

A new study from MBARI researchers and their collaborators using SOCCOM float data has revealed that storms trigger the release of carbon dioxide from the ocean. This work will help improve models used for forecasting our changing climate. Dive in: www.mbari.org/news/new-res...

Took 2+ years, but look what finally showed up!
