Late post for #CTDAppreciationDay 🌊🧪
Our amazing #AT50-37 STEMSEAS students wrangling the CTD on our transit from San Diego, CA to Dutch Harbor, AK.

On the NES-LTER (@nes-lter.bsky.social) winter cruise aboard the #RVNeilArmstrong, the science team conducted incubation experiments to better understand plankton grazing behavior across the northeast shelf.
#CTDAppreciationDay 🚢 🌊
I forgot to post this yesterday for #CTDAppreciationDay ...it's the "Nansen bottle chant" written and performed by SEA Education Assoc founders and participants in the 80s.
I can't believe that @clarkgrichards.bsky.social forgot to include an example of an #Argo float for #CTDAppreciationDay, one of the most important CTD-equipped platforms for understanding the global ocean. There are currently 4091 operational floats, profiling every 10 days and sending data back! 🌊
I love that! Hopefully we can catch up at a meeting one day!
🌊 Happy #CTDAppreciationday to all you who celebrate!!!
Happy #CTDAppreciationDay from the #LivingBioreactors cruise on the Falkor too. Our CTD is friends with an ISIIS-DPI shadowgraph camera. @schmidtocean.bsky.social @mbarinews.bsky.social #OBVI

🌊 🚢 Happy #CTDAppreciationDay! The #CTD measures conductivity, temperature, and depth, and supports countless #URIGSO research efforts! ⬇️ ⬇️ ⬇️

Summer fieldwork for the Ocean Margins Initiative (OMI) project in Ghana, co-led by #URIGSO's Melissa Omand. The new Seabird SBE 55 ECO CTD was purchased by the University of Ghana, with installation aboard the Ghanaian Navy vessel GNS AFLAO.

12 Rhode Island educators stepped into the role of shipboard scientists aboard #RVEndeavor for a three-day research cruise, steaming 100 miles out to the shelf break and back. They worked with #URIGSO scientists, crew, & marine techs to conduct CTD profiles! #CTDAppreciationDay 🌊 🚢
Happy Conductivity, Temperature, Depth (CTD) Appreciation Day! Today, #BigelowLab is reflecting on this tool’s role as a pillar of our field. Pictured are Colby College students using a CTD aboard the R/V Bowditch in October 2025. #CTDAppreciationDay #ocean #science
A device (rosette) being lowered into the sea (greenish waters). It's formed by several Niskin bottles (grey) and a ctd (white) with a metal frame.
It always feels good to celebrate the #CTDAppreciationDay 🌊🧪 (it's the white tube to the left in the rosette, the grey ones are Niskin bottles), here during our 2025 field work with @universitedeliege.bsky.social students, on-board the Simon Stevin, from @vliz.be. Muddy North Sea waters!! 😅
Happy #CTDAppreciationDay to all who celebrate (and we do)! Here's how researchers are studying Arctic fjords with crowdsourced science, sailboats, and CTDs. eos.org/articles/stu...
It’s probably oceanography’s most important tool. Today, warm deep water impinges onto the Amundsen Sea shelf, causing melting of the underside of floating ice shelves, destabilizing the glaciers. Here we deployed a CTD-rosette to precisely sample the inflow of this deep water.
#CTDAppreciationDay
Apparently it's #CTDAppreciationDay again. Please check out the most important tool in oceanography. 🌊
Happy #CTDAppreciationDay! You make sampling the subsurface ocean possible!
Thank you, Fabrice, for sharing all of these details about rogue waves, including your personal connection through your friend's near tragedy.
#dailyoceanterm on pause, or 'hiatus' if you will. I'll try to bring more energy to this in the future.
#dailyoceanterm
Atoll: "horseshoe or circular array of islands, capping a coral reef system perched around an oceanic volcanic seamount"
Used in a sentence: I really don't understand this atoll.

#dailyoceanterm 🌊
thermocline: in the ocean, a layer of water where temperature rapidly decreases the deeper you go. It can be shallow or deep, with more well mixed warm water above and cold water below.
Used in sentence: A sharp thermocline divides us, but we are all made of water.
#dailyoceanterm 🌊
Abyss: a deep gulf or great space; abyssal: ocean depths below 3000 or 4000 meters.
Used in sentence: We really are looking into the abyss.
#dailyoceanterm
alkalinity (of sea water): buffering capacity of a sea water body; it is a measure of seawater's ability to neutralize acids and bases and thus keep a fairly stable pH level
Used in a sentence: Like in the ocean, my alkalinity is being tested.
If I get a definition of a #dailyoceanterm a little wrong due to oversimplifying, I'm glad my science network is there to provide the nuance or information that I'm missing. It takes a science village!
My latest: The mass firings at NOAA can feel abstract. Here's what was lost at one research center -- the birthplace of climate modeling.
Fired staff became U.S. citizens to pursue these dream jobs, only to have their dreams upended.
#dailyoceanterm
Surface tension: Property of a liquid which allows the surface to resist an external force due to the cohesive nature of the liquid's molecules.
Used in sentence: Wow, you could almost cut the surface tension with a knife!
Thank you for the correction, I should have said "greater than 2.1 times the significant wave height" recognizing that a better threshold is needed to capture what makes them dangerous.
Thank you, Fabrice. What would you define as a better threshold and information to convey. I value your input!
