New research led by the University of Miami Rosenstiel School of Marine, Atmospheric, and Earth Science with @globaloceanbgc.bsky.social has found that nitrogen cycling in marine oxygen-deficient zones is far more dynamic than previously thought. 🌊🧪 Learn more: www.mbari.org/news/mbari-t...
Two men hold a long yellow cylinder and are in the act of deploying it over the side of a boat. Both are wearing red jackets and blue hard hats. the ocean is seen in the background and to the right of the frame.
The BGC-Argo profiling array is engaging students and educators to foster ocean literacy as we work to deepen the understanding of the ocean’s role in climate: link.springer.com/chapter/10.1...

New research highlights how upwelling shapes Monterey Bay 🌊
MBARI researchers used data from monthly autonomous underwater vehicle transects to reveal strong seasonal patterns linked to upwelling that structure ecosystem variability in Monterey Bay.

To predict how oxygen-depleted areas of the ocean will evolve, scientists must observe the invisible chemistry that drives them, writes Mariana Bif @miamirosenstiel.bsky.social (and formerly at @mbarinews.bsky.social).

🧪📍🌊 🦑🍎 Design a sticker competition for @globaloceanbgc.bsky.social - deadline Feb 9 at midnight pacific time www.go-bgc.org/outreach/202...
🍎 @globaloceanbgc.bsky.social want to adopt a float?? Get real data into the classroom? It's free ;-) www.go-bgc.org/outreach/ado...
7/ Hats off to authors Steve Rintoul, Esmee van Wijk, Laura Herraiz-Borreguero and Madelaine Rosevear from CSIRO, AAPP, @utas.edu.au and @imas-utas.bsky.social – with support from @imos-aus.bsky.social – and the intrepid #Argo floats.

Today's satellite shoutout 🛰️ is to NASA PACE, which gives us data of ocean color, biogeochemistry, and ecology! 🌊 🧪
Here is chlorophyll-a (signature of photosynthesizing plankton) along with ocean current magnitude and direction (arrows). The red dot is where I currently am on the RV Sikuliaq! ⛴️
A Christmas gift to the ocean from the team aboard the RV Sikuliaq: one specially wrapped biogeochemical-Argo float from @bgc-argo.bsky.social! 🌊
Profiling floats allow us to get real-time ocean data, helping us be in tune with ocean health and changes.
🧪📍🌊 🦑🍎 adopt your own float!! www.go-bgc.org/outreach/ado...
Frequency hopping enables cell phone tech. Hedy Lamarr is in the National Inventors Hall of Fame and her Wikipedia page is

Depth (0 to 300 m) by time (2022 to 2026) plots of temperature, salinity, particulate organic carbon (POC), chlorophyll (CHL_A), oxygen, nitrate, pH at in situ temp/pressure, and computed dissolved inorganic carbon (DIC) for float 5906497 (adopted name Hedy Lamarr).
🌊BGC-Argo float of the month is 5906497 with 4 years under Antarctic sea ice, just popped out. It was adopted by the American School in Jeddah, Saudi Arabia and named “Hedy Lamarr” – the actress who co-invented and patented frequency hopping communications. Named for her science contribution. 1/2
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.

Schematic showing oxygen dynamics in the subpolar North Atlantic Ocean
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

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
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.
100 years ago, research vessel #Meteor set sail to explore the Atlantic Ocean – one of the most important expeditions of the 20th century. To mark the anniversary, GEOMAR and DSM/Leibniz-Institut für Maritime Geschichte launched a storymap.

How cool is this? A LEGO Argo Float! Thanks for the inspo @mbarinews.bsky.social! "Treated" everyone in the brick store to a 5min ad-hoc talk why Argo Floats are so cool and important. Shouldn't have asked what I'm building 🙃
✅Permanent Ocean Monitoring
✅Aid weather/climate forecasts
✅Free/open data
A decade of BGC-Argo and plankton records shows North Pacific heatwaves reshape food webs and trap small particles in midwater, slowing deep-ocean carbon export. Impacts vary by event, underscoring the need for sustained ocean monitoring. @mbarinews.bsky.social @miamirosenstiel.bsky.social
Revealing the ocean’s hidden chemistry 🌊
A new statistical approach developed by researchers @mbarinews.bsky.social & @miamirosenstiel.bsky.social enables detection of nitrite and thiosulfate in oxygen-deficient zones.
