#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. Definition source: you.stonybrook.edu/marinebio/gl...

🚨**Job advert** 🚨 We are hiring a seagoing technician in Hamburg! Interested in going to sea, handling instrumentation (ship-based, moored, glider) and logistics of research-travel to remote places? See the advert - contact me with any questions. Deadline 4 April. eleanorfrajka.com/post/2025-03...

#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!

#dailyoceanterm Rogue wave: unpredictable, uncommon wave bigger than twice the size of surrounding waves. They can have steep sides & deep troughs. Used in sentence: The idea of a rogue wave is terrifying, thankfully they are rare. Definition Source: oceanservice.noaa.gov/facts/roguew...

#dailyoceanterm Coriolis effect: effect that makes objects including air and water traveling long distances around Earth move at a curve instead of straight line. Used in sentence: Isn't the coriolis effect a cool feature of our spherical, rotating earth? Info Source: scijinks.gov/coriolis/

#dailyoceanterm turbidity current: "a rapid, downhill flow of water caused by increased density due to high amounts of sediment." Used in sentence: Today, I learned more about turbidity currents. Thank you, NOAA, for the info! Definition Source: oceanservice.noaa.gov/facts/turbid...

#dailyoceanterm Ocean: "the whole body of salt water that covers nearly three fourths of the surface of the earth" Used in a sentence: We could fill an ocean with our tears. Definition Source: www.merriam-webster.com/dictionary/o...

#dailyoceanterm Salinity: in the ocean refers to how much dissolved solids (e.g. sea salt) are dissolved in seawater, on average about 35 parts per thousand (3.5%). Used in sentence: Would the saltiness we are feeling register as high or low salinity value?

#dailyoceanterm Ocean Trench: "long, narrow depressions on the seafloor. These chasms are the deepest parts of the ocean..." Used in a sentence: We are in the ocean trenches, doing the best we can. Definition Source: education.nationalgeographic.org/resource/oce...

#dailyoceanterm Maelstrom: "a powerful often violent whirlpool sucking in objects within a given radius" Used in sentence: I don't know if this is a maelstrom, but it sure does suck. Definition Source: www.merriam-webster.com/dictionary/m...

#dailyoceanterm Fetch: fetch, area of ocean or lake surface over which the wind blows in an essentially constant direction, thus generating waves. Definition Source: www.britannica.com/science/fetch Used in sentence: These aggressive new winds will have untold fetch.

I want to see every scientific society going into emergency mode. This is a good example of how an organization can flex its specific power in a time of great need. What else is possible?

#dailyoceanterm Tsunami: "a great sea wave produced especially by submarine earth movement or volcanic eruption" Used in sentence: They came for us like a tsunami. www.merriam-webster.com/dictionary/t...

The Trump administration has blocked work that is central to major international climate change research, and barred federal scientists and diplomats from attending a key global climate event in China next week, according to three sources close to the situation.

#dailyoceanterm shelf break: "submerged offshore edge of a shallow continental shelf, where the seafloor transitions to continental slope." Source: www.britannica.com/science/shel... Used in sentence: We were on a shelf break!

This is entirely preventable. Science solved this problem more than 60 years ago.

Ocean term of day: Abyssal plain: any of the great flat sediment-covered areas of ocean floor. Used in a sentence: I'll bet things are calm on the abyssal plain. www.merriam-webster.com/dictionary/a...

#CTDAppreciateDay During my PhD, we used the CTD in the Santa Barbara Basin on R/V Atlantis to understand more about the basins ocean biogeochemistry 🌊

Did someone say #CTD appreciation day? Here’s to measuring the depths one bottle at a time! 🌊

#CTD appreciation day. We undertook a CTD this afternoon on the FS Sonne offshore SE NZ which had a lot of unexpected structure…. 🌊🚢🪸

Today is #oceanexplorationday! On this day in 1960, Jacques Piccard and US Navy Lieutenant Don Walsh were the first to reach a record depth of approximately 10,911 meters (35,797 ft) in the research bathyscaphe Trieste in the Challenger Deep of the Mariana Trench near Guam in the Pacific.

The best classroom experiences I ever had were when we had a guest in the classroom who was passionate about a subject. Enthusiasm is contagious!

Happy #OceanExplorationDay, to honor the historic #ChallengerDeep dive made on this day in 1960. And congrats to the all-girl @lego robotics "Team Imagination" for your prize at the "Submerged" FIRST LEGO League Championship for all of southern California! You got next!!! 🌊 🦑

I vote for A

Apparently it's #CTDappreciationDay, so here is one I took of my @dmidk.bsky.social colleagues and out collaborators in #Greenland, waiting for the winch to pull it up through the #SeaIce (Somehow, I always expect a halibut to be entangled in it but there never is...)

If it's #CTDAppreciationDay, a reminder that CTD measurements are sometimes taken on dives by seals.

Happy #CTDAppreciationDay! 📷 of the RVIB Nathaniel B. Palmer in east Antarctica when I was doing outreach for @hollybik.bsky.social

Happy #CTDappreciationday, the workhorse of modern oceanography (hidden between the bottles of the rosette tbh, but these two often get deployed as a team). Here it’s just returning from a run off the Pine Island Glacier (75°S) and helped to understand incoming warm water masses a bit better.

This #CTD is equipped with additional instruments to measure dissolved oxygen and pH, helping scientists gain a more detailed understanding of the underwater environment around coral reefs and other areas of interest. 🐠🪸 #CTDAppreciationDay @marecotec.bsky.social

Happy #CTDAppreciationDay! Here I show you the latest kids on the team: two SBE45 before assembling in our underway equipments. The core 💙 of BOGAR! 🚣🏽

Happy #CTDAppreciationDay! The next generation of the OpenCTD needs a little bit of polish, but the new board is good and the data is coming in clean! 🌊

Apparently it’s #CTDappreciationDay so here’s an old pic from 25 years(!) ago on Lake Tanganyika as part of the #NyanzaProject. Fantastic experience that summer. I miss fieldwork more than I can adequately express.

I almost forgot about #CTDappreciationDay! There aren't many aspects of my job that don't rely on CTD data. Here are some photos of our trusted SBE CTD and rosette sampling the Canadian Northwest Passage, the cutest little CTD on a turbulence profiler (made by JFE), and a glider CTD made by RBR.

One of my favorite CTDs, one of three custom SBE 49s that went to the bottom of the Marianas Trench. Rated to 12K meters, with super thick titanium casings, it pushed the limits of sensor engineering & performance. I know because I got to hold them and check out the data! #CTDAppreciationDay

D: may you have an interesting cast B sounds like an invitation to doom as sometimes they don’t 🫣

It’s our favorite day of the year—Happy #CTDAppreciationDay! 🎉 This shot captures a nighttime deployment of a 12-plume #CTD by MATE Intern Josie Adams aboard the #RVEndeavor from cruise EN719 last summer. Also featured is #URIGSO marine tech Bonny Clarke, who is crucial in supporting these missions!

Happy #CTDAppreciationDay! CTD stands for Conductivity, Temperature, and Depth— a package of instruments that measure these essential properties. Such a workhorse of a device, definitely deserving of its own day 🏅 What other instrument should we all celebrate & why? Tell us in the comments! ⬇️

Wow! #CTDappreciationday is here and @planktonteuta.bsky.social posted me next to a CTD! Indeed going at sea to collect optical properties is a crucial aspect of our work to ensure that satellite retrievals are accurate. 🌊🛰️

Seeing lots of great photos on #CTDappreciationDay, but mostly open ocean shots... Where are our coastal and estuarine folks at? 😍

CLASSIC. #CTDAppreciationDay

What should the greeting be from one oceanographer to another on #CTDAppreciationDay be? A: "May the cast be ever in your favor" B: "What goes down must always come back up" C: "This cast is always fresh with no modulo errors yet"

It's #CTDAppreciationDay! I have a lot of love for this instrument and the many platforms we can use it on - including an aerial drone! www.linkedin.com/posts/voiceo...

For #CTDAppreciationDay my first Bluesky post: We were tracking the oil plumes at depth using the CTD and UV fluorometer from the F.G. Walton Smith during the Deepwater Horizon response. This was the morning after the flaring started from one of the relief drilling ships.

#CTDappreciationday even in a bath (trashcan), CTD can enjoy views on the Stromboli 🌋🌋🌋
