💁🏻♀️ TIL: 🛸🌊 A #NOAA #ROV explores abyssal plains near the #CookIslands in the #SouthPacific, mapping the deep seafloor and #water column with sensors while live streaming nearly daily through August 13. Divers have already spotted carnivorous #sponges that capture small #crustaceans, a surprising find for habitats once thought sparse.

Microplastics in the Water Column
Of the more than 9 billion metric tons of plastic that’s been produced, a mere 9% has been recycled. About 12% has been incinerated, and the remainder is just out there–in our homes, our landfills, and, unfortunately, in our oceans. Exactly where all the plastic is continues to be an active question of research.
Plastic’s density is similar to that of water; some versions are a little denser than water, and some are a little lighter. So whether a piece of plastic floats at the ocean surface or sinks to the bottom depends on several factors, including its density, size, and shape. A large, dense plastic–think laundry detergent bottles–can float if it displaces enough water; after all, metal ships float!
But as sunlight and abrasion breaks that big container into smaller fragments, their buoyancy shrinks. Eventually, these small, millimetric pieces sink, carrying our pollution to ecosystems we once thought remote. Some of the highest rates of microplastic ingestion are found in nonmigratory species living between 1200 and 1500 meters below the surface. We may never visit those depths, but our garbage does.

Climate inertia (Glaciology 🗻)
Climate inertia or climate change inertia is the phenomenon by which a planet's climate system shows a resistance or slowness to deviate away from a given dynamic state. It can accompany stability and other effects of feedback within complex systems, and includes the inertia exhibited by physical movements of matter and exchanges of energy. The t...

🏄♀️While some of you might be off chasing waves at the beach, we're chasing the ones you can't see.🌊A stunning visualization from our researchers Moritz Epke&Nils Brüggemann (now at ZMT Bremen) shows vertical velocity at 1641 m depth based on a novel #ICON configuration with a flexible telescoping grid that achieves a resolution <1 km across the southeastern Atlantic.👀Watch until the end to see what happens when tidal forcing is switched off. https://vimeo.com/1210107808?share=copy&fl=sv&fe=ci

One of the most complex #visualizations of #Earth’s ocean dynamics to date, by #NASA.
Leveraging #satellite #altimetry, #scatterometry, and state-of-the-art numerical #ocean #models, the #map exposes the planet’s vast current systems: oceanic jets, #mesoscale eddies spanning hundreds of kilometers, and the Gulf Stream.
(Looks quite a bit like Van Gogh’s Starry Night! Yet, this is pure fluid dynamics, no #AI involved.)

TIL that if the rocky part of the Earth were a smooth sphere, then the oceans would cover it completely to a depth of about 2 kilometres (1.2 miles).
Of course, the actual Earth isn’t a smooth sphere, so we have ocean basins and continents.

RAFOS float (Oceanography 🌊)
RAFOS floats are submersible devices used to map ocean currents well below the surface. They drift with these deep currents and listen for acoustic "pongs" emitted at designated times from multiple moored sound sources. By analyzing the time required for each pong to reach a float, researchers can pinpoint its position by trilateration. The floats are able to detect the pongs at ranges of hundr...

The submersible vehicle on today’s Schmidt Ocean Institute sea floor mapping expedition has been returning to the surface for the last few hours. From 2.9 km deep. It’s currently at 780 metres and rising about a metre every 1 to 2 seconds. It should surface in about 15 minutes or so. Hopefully, the cameras will be on and streaming until then.

My #oceanography colleague Denise Fernandez is voyage leader in the Cook Islands region mapping ocean temperatures.
She was my co-voyage leader on Tangaroa last year when we went to literally the coldest part of the oceans in the outflow of the Ross Ice Shelf - and now she's taken Kaharoa II to measure El Nino ocean temperatures.
This is epic stuff and rather unheard-of for one person to lead voyages to both extremes in such a short space of time. And jeepers that ocean is warm. #climate #ocean #oceanheatcontent #climateemergency

🌊 Long before the term #TippingPoint was coined, oceanographer Henry Stommel discovered that the thermohaline circulation could exhibit multiple equilibria—&that small perturbations could trigger transitions between them. His 1961 Tellus paper underpins today’s research on the #AMOC.
📃 On the occasion of Tellus’s relaunch&the paper’s 65th anniversary, our director Jochem Marotzke analyzes its reception from the circuitous early history to its lasting legacy: https://tellusjournal.org/articles/10.16993/tellus.4175
