🌊@helenczerski.bsky.social gave a talk on physical oceanography.

A panel of scientists presented their favourite oceanography equipment, getting the audience to vote on which kit to throw off a sinking ship; the ROV was saved.

One day : SO MUCH OCEAN SCIENCE!

🦆 The National Maritime Museum brought a Micronesian navigational chart & a 1992 Friendly Floatee duck.

🐬@strandings.bsky.social brought cetacean skulls & a find-the-otoliths-in-dolphin-poop activity

🦪@glasgow.ac.uk made the case for native oysters.

Visitors were shown how @ucl.ac.uk palaeoceanographer sort forams to infer past climates; the same idea behind palaeoclimate research but adapted 8-year-olds!

Plus a the marble climate tipping machine that showed how small incremental changes can trigger massive instabilities.

We showcased the @noc.ac.uk recent Channel 4 segment & HongdouFan's AMOC visualisations on the EPOC stand.
Audiences explored ocean currents using a Puffersphere globe & saw how warming seas destabilise marine food webs.
@samsocean.bsky.social showcased AUV gliders & water mixing experiments.

As researchers gathered at #OSM26, we saw nearly 2000 people through @glasgowscience.bsky.social for Eyes on the Ocean showcasing the breadth & depth of ocean science to half-term families who left knowing what AMOC is and why it matters.

48 scientists. 22 institutions. 1 question:
Can #AMOC mooring arrays become platforms for biogeochemical observing?

We brought together oceanographers, biogeochemists, engineers & data scientists to find out.

Spoiler: the answer is yes.

This provides new constraints for evaluating Atlantic Meridional Overturning Circulation (#AMOC) behaviour across different climate states.

This also brings palaeo-reconstructions into closer agreement with climate models; useful for testing model performance under more extreme boundary conditions.

Relatively warm deep-water formation persisted in the Last Glacial Maximum - Nature During the Last Glacial Maximum, the deep Northwest Atlantic was only about 2 °C colder than today, suggesting sustained production of relatively warm North Atlantic Deep Water during the Last Glacial...

New @nature.com paper from Jack Wharton @ucl.ac.uk.

Using deep-ocean sediments, the study shows that North Atlantic Deep Water (NADW) formation during the Last Glacial Maximum persisted at similar depths to today & was much warmer than previously assumed.

📣 New EPOC results reveal that during the last ice age the Atlantic’s powerful current system remained active and continued to transport warm, salty water from the tropics to the North Atlantic despite extensive ice cover across much of the Northern Hemisphere.

We left yesterday from sunny Tromsø for the annual #FramStraitNPI cruise aboard #FFKronprinsHaakon! We'll spend the next 3 weeks at around 79°N in Fram Strait, collecting lots of oceanographic data and samples for the @epocproject.bsky.social and several other projects. Stay tuned for updates!

The first three EPOC expeditions this summer/autumn... this one 👇 led by @oceanseaicenpi.bsky.social, the M212 mission aboard RV Meteor led by @unibremen.bsky.social starting later this week, and @ifremer.bsky.social CROSSROADS2 expedition in Sept-October. More details: epoc-eu.org/epoc-gears-u...
