“The squid, which was about 75cm long, descended on our camera assuming it was prey, and tried to startle it with is huge bioluminescent headlights,” Associate Professor Stewart said.
PODCAST: Levke Caesar: “Oceanic Slowdown: Decoding the AMOC”
By Nate Hagens, originally published by The Great Simplification May 24, 2024
"...Nate is joined by climate physicist Levke Caesar for a comprehensive overview of the Atlantic Meridional Overturning Circulation (AMOC) and its connections to broader planetary systems. Amid a complex...interconnected climate system, the AMOC is a powerful force for regulating temps between the Northern & Southern Hemispheres along the Atlantic Ocean – yet it’s estimated to have slowed down by about 15% over the last few decades. What are the possible domino effects of this slowing oceanic powerhouse at a regional & global scale? How well do we understand what drives the AMOC, its cyclical patterns, and connections with other currents? ...how does the AMOC interact with other biospheric mechanisms that have shaped our stable, life-supporting planetary home?"
“Scientists can now use climate data to predict whale and sea turtle locations months in advance, helping fishing fleets avoid conflicts with wildlife.”
Astronomer Angelo Secchi demonstrates the Secchi disk, which measures water clarity, aboard Pope Pius IX's yacht, the L'Immaculata Concezion.
It is a plain white, circular disk 30 cm in diameter used to measure water transparency or turbidity in bodies of water. The disc is mounted on a pole or line and lowered slowly down in the water. The depth at which the disk is no longer visible is taken as a measure of the transparency of the water (Secchi depth).
Today, learn about the 32 U.S coastal cities, affecting up to 500,000 people, that are at an increased risk of experiencing one or more major flooding events in the next twenty years, due to land subsidence and sea-level rise. https://news.vt.edu/articles/2024/01/research-sinkingcoasts.html
Crabs, kelp and mussels: Argentina’s waters teem with life – could a fish farm ban do the same for Chile?
While the ecosystem is thriving off the coast of Argentina, the proliferation of salmon farms in Chile’s waters is threatening marine life, say critics
Weekend #Plankton#Factoid 🦐🦠
The ubiquitous tool of #zooplankton#science is the Plankton Net. The first documented use was by British surgeon Dr John Vaughan Thompson to catch the brightly coloured copepods Sapphirina and barnacle larvae. Darwin brought these nets on the HMS Beagle. Originally fine muslin, then silk, now are highly accurate sized meshes of nylon. Modern quantitative #oceanography nets with removable cod-end have been standardized since late 1800s and named for Victor Hensen.
Is the Atlantic Overturning Circulation Approaching a #TippingPoint?
Studies show that the Atlantic Meridional Overturning Circulation (#AMOC) has already weakened as a result of anthropogenic #ClimateChange and is possible moving towards a tipping point. This current has a significant influence on #climate, particularly in #Europe.
Swiss scientist Alexander Agassiz died #OTD in 1910.
He assisted Charles Wyville Thomson in the examination & classification of the collections of the 1872 Challenger Expedition, and wrote the Review of the Echini (2 vols., 1872–1874) in the reports. Agassiz's legacy lies in his contributions to marine science & geology particularly his studies on coral reefs and his efforts to advance the field of oceanography.

Swiss = suspicious
Switzerland is the center o human social system and is run by freemasons.
The central planner is the "Great Architect" of the freemasons. That is a real alien object hidden inside Gottard tunnels in Switzerland. Entrance near Sedrun via Porta Alpina. Read more here: http://realalieninvasion.free.nf/
did a radio podcast thing for our #Antarctic voyage - it was a great conversation (Sharon Brettkelly was so on to it) but I rambled as usual - the team at Radio NZ crafted a great (and dare I say important) story. And our PhD student Liv just aced it with enthusiasm to counter my school principal vibe. #DoYourSelfaFavour#climate#oceanography#polynya
