SAMS CLIMATE CHANGE STUDY : ATLANTIC OCEAN CURRENTS : NO CLEAR SIGNAL THAT THE AMOC IS WEAKENING AT THE SUB-POLAR LATITUTE
Marine scientists in Scotland have helped to develop the most comprehensive view yet of how large-scale north Atlantic currents that dictate our climate may be changing.
EXCERPT: Oceanographers across the world have long hypothesized that the AMOC could be weakening because of climate change, a view partly supported by a sub-tropical array of moorings known as RAPID, which has been in place since 2004. Because AMOC transports heat northwards from the tropics, a weakening, or complete collapse, of this ocean system could potentially plunge western Europe into freezing temperatures more commonly associated with higher latitudes such as Greenland and Siberia.
Project lead Dr. Neil Fraser of SAMS said SCOTIA had shown no clear signal that the AMOC was weakening at sub-polar latitude, but added this did not necessarily mean there was no overall weakening over a longer period of time. "The creation of the SCOTIA array and the methods we used to gather this data mean we are a step closer to answering one of the biggest questions in ocean science: is the AMOC weakening? It will allow us to effectively keep our finger on the pulse of the AMOC to give us the best chance of detecting a weakening or collapse."

YELLOW BRICK ROAD AT THE DEEP BOTTOM OF THE OCEAN?
Is this THE YELLOW BRICK ROAD? Liliʻuokalani Ridge Seamounts
SCIENCE ALERT : YELLOW BRICK ROAD OFF HAWAIIAN ISLANDS
Excerpt: Trust/E/V/Nautilus/YouTube)
The formation has been identified as "a fractured flow of hyaloclastite rock (a volcanic rock formed in high-energy eruptions where many rock fragments settle to the seabed)."
On the radio, the team notes that the ground looks almost like a "baked crust" that could be peeled off.
In one tiny section, the volcanic rock has fractured in a way that looks strikingly similar to bricks.
"The unique 90-degree fractures are likely related to heating and cooling stress from multiple eruptions at this baked margin," reads a caption to the YouTube video.

ARE YOU CONSIDERING BECOMING A MARINE SCIENTIST?
Once in a while someone tells me that viewing SIREN'S LINK TO SEA inspires them to consider a career in MARINE SCIENCE...

MARIANNA TRENCH : THIS MINI DOCUMENTARY MAY UPSET YOU : WAIT TILL YOU FIND OUT WHAT THEY FOUND ALL THE WAY DOWN IN THE TRENCH
The Marianna Trench is the deepest place on earth. It is deeper than the tallest mountains. And it went unexplored for decades due to the extreme pressure. Watch this film all the way and let me know what you feel!

Siren here!
We are going to the https://www.ocearch.org/tracker/detail/contender OCEARCH TRACKER SITE SO YOU TOO CAN WATCH CONTENDER SWIM!
What is his territory if he has one?!
over 1600 pounds too!
*** He keeps pinging !

GOLDEN SHARK CAUGHT OFF COAST OF COSTA RICA
REAL CLEAR SCIENCE : GOLDEN SHARK CAUGHT
Excerpt: One spectacular example of this is a nurse shark (Ginglymostoma cirratum) caught and released by sports fishers off the coast of Costa Rica in August 2024. Not only was this shark not its usual brown cookie-dough color, but it was vividly orange-colored – with white eyes, to boot.************
WHY IS THIS SHARK THAT LOOKS TO BE THE COLOR OF A GOLD FISH ORANGE? sHE LIKES WARM WATER TOO!
Click on the link to see the photo! Almost unbelievable!

FIRST SHARK OFF ANTARCTICA CAUGHT ON CAMERA - WHY IT MATTERS
FORBES : ANTARCTICAS FIRST SHARK CAUGHT ON CAMERA
Excerpt: Sharks have survived mass extinctions, shifting continents and dramatic climate swings for more than 400 million years. They patrol coral reefs, cruise open oceans, call kelp forests home and rule the deep sea. And while Greenland sharks (Somniosus microcephalus) are known to rule the icy, dark waters of the Arctic Ocean, the Antarctic landscape has long been barren of this predator. The Southern Ocean is frigid, remote and punishingly cold, with temperatures dipping below zero. Which is why new footage captured near the South Shetland Islands is so remarkable: for the first time, a shark has been recorded on video in the Southern Ocean itself.4/5/26
TOM GRUBER FIRST FOOTAGE OF HAWAIIAN DAY OCTOPUS WHO RECOGNIZED HERSELF ?! DO YOU AGREE?
I think Octopuses might be the most intelligent of sea creatures, other than the whales. In this video, Tom Gruber, the inventor of Siri, filmed one that saw itself in a mirror. To be honest, I think the octopus saw another octopus. DO YOU THINK IT KNEW IT WAS LOOKING AT ITSELF?

BLUE MARINE FOUNDATION : ACTION TO PROTECT OUR OCEAN : LET'S PROTECT 30 PERCENT OF THE OCEAN BY 2030
BLUE MARINE FOUNDATION 4.9 KM of OCEAN PROTECTED
Blue Marine is dedicated to protecting and restoring life in the ocean. Our mission is to see at least 30 per cent of the ocean protected by 2030 and the whole ocean sustainably managed. We support low-impact fishing and equitable use of the ocean and address overfishing – one of the world’s biggest environmental challenges.

This is the time to check in with yourself. Are you overeating seafood?

ORCAS HAVE BEEN SINKING BOATS
It's true... there have been a number of reports.
DIVE MAGAZINE : ORCAS SINK BOAT - PORTUGAL
OUTSIDE ONLIE : WE SAILED THROUGH ORCA ALLEY - BOATS RAMMED -SINKING
Excerpt: Along the Iberian Peninsula, where the North Atlantic collides with the rugged coastlines of Spain and Portugal before pinching into the Mediterranean Sea, an endangered subpopulation of orcas has developed the unfortunate habit of ramming into sailboats. The powerful animals target the rudders, often breaking them and destroying or disabling a boat’s steering. Such force can sometimes also damage a boat’s hull and cause a leak.
Orcas, also called killer whales (Orcinus orca), are known for their prowess as marine predators, and they’re intelligent and highly social. Across their global range, they’re unusually flexible in what they eat, how they hunt, and where they call home. Among their many talents, they’re masters of surprise.
