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.

ANTARCTIC MELTING??? CHECK THE NATIONAL SNOW AN ICE DATA CENTER!
NSDIC - ICE SHEETS TODAY NATIONAL SNOW AN ICE DATA CENTER MAPS, CHARTS, REPORTS!
Excerpts: After setting records in December and January for melt extent in the 47-year satellite record, melt extents dropped abruptly by early February when conditions over the Antarctic Peninsula cooled. Overall, the number of melt days exceeded the 1991 to 2020 long-term average by approximately 10 days in the Larsen C Ice Shelf area, 15 days in the Fimbul Ice Shelf area, and over 30 days along the eastern side of the Amery Ice Shelf. Also notable were above average melt days in the West, Shackleton, and Totten Ice Shelf areas. The Sulzberger and Ross Ice Shelves were among the few areas with below average melt days for the austral summer season. Extensive ponding apparent in January in satellite images on the Larsen B remnant, known as Scar Inlet Ice Shelf, and northern Larsen C, all refroze in February; however, ponding and some surface melt flow were still visible on the Amery and Roi Baudouin Ice Shelves into March, although with a frozen surface at that point.

ICEBERG THE SIZE OF CHICAGO LET GO FROM ANTARTICA
NASA EARTH OBSERVATORY - ICEBERG SPEEDS AWAY
Excerpt: Named A-84 by the U.S. National Ice Center, the berg measures about 30 kilometers (19 miles) long and 17 kilometers (11 miles) wide. It has an area approaching the size of Chicago, Illinois.
Iceberg calving is a normal occurrence for ice shelves. However, factors such as warming air and water along with decreasing protective sea ice can accelerate calving and lead to collapse, as has happened to several ice shelves along the Antarctic Peninsula.
Observations made by explorers beginning in the early 1940s, and later by remote sensing, show that the George VI has been losing shelf ice. For now, the retreat has been gradual, aided by the stability provided by its unique location, sandwiched between the Antarctic Peninsula and Alexander Island. *** Siren here! As we know, iceberg melt can raise the sea level. Other, larger bergs have broken off and gone to sea...

THE LAST OCEAN : ANTARTICA'S ROSS SEA PROJECT : SAVING THE MOST PRISTINE ECOSYSTEM ON EARTH
A fantastic book (think of it when gifting!) full of adventure and amazing photography. Some of the subjects... way more than I could put in labels... Emperor Penguins, Adelie Penguins, Minke Whales, Killer Whales, The Ross Ice Shelf, McMurdo Research Station, Shakelton's Hut (circa 1908 - a historical monument to survival), underwater Antarctica, Weddell Seals....
HOW SEALS USE THEIR LUNGS TO DIVE DEEPER AND THIER INCREASED CAPACITY TO USE OYGEN.
THE FORMATION OF SEA ICE... BLUE ICEBERGS...
BY THE EARLY 1970's THE WHALE POPULATION HAD PLUMMETED BY 90%.

NEW ANTARTICA SEA CREATURE WITH TWENTY LEGS THAT LOOKS LIKE A STRAWBERRY AT FIRST GLANCE!
Excerpt: Antarctic feather stars are 'large' animals that can live anywhere from about 65 feet to about 6.500 feet underwater and have an 'otherworldly appearance' when swimming, researchers said. Although both are invertebrate ocean animals, feather stats are distinct from more well-known sea starts.
During their surveys, researchers collected eight feather stars with a distinctive body shape and discovered a new species: Promoachocrinus fragarius of the Antarctic Strawberry Feather Star...
Great photo and more information of the creature's colors and overall appearance!

BLUE WHALES MAKE A COMEBACK - 55 NEAR ANTARCTICA
DAILY MAIL SCIENCE TECH - 55 BLUE WHALES NEAR ANTARCTICA Another extensive articles with photos and a video...
EXCERPT: The critically endangered blue whale, the largest animal ever to have lived, is making a comeback, marine scientists say.
A total of 55 blue whales were sighted or recorded in the past year, according to the British Antarctic Survey, which has been studying whale movement in waters surrounding South Georgia Island in the South Atlantic Ocean. ... It reaches a maximum length of 98 feet - the same length as two and a half London buses. ... They were hunted almost to extinction by whaling until the International Whaling Commission banned all hunting of blue whales in 1967

WHALE MOMS WHISPER TO BABES TO AVOID PREDATORY ORCAS
NEW SCIENTIST - WHALE MOMS WHISPER by Micheal La Page
EXCERPT: The whales feed near Antarctica during the summer and then migrate north to coastal waters during the winter to give birth and breed. The mothers and calves remain there for three months and often keep very close to shore, just beyond the breaking waves.
It is suspected they do this because the noise of the waves helps mask any sounds they make and thus makes it harder for predators such as killer whales and sharks to find them. The findings of Mia Nielson of Aarhus University in Denmark and colleagues suggest this is indeed the case.

ICEBERG ANTARTICA - MYSTERIOUS SEA FLOOR EXPOSED
GIZMONDO - MYSTERIOUS SEA FLOOR EXPOSED - ANTARTICA
EXCERPT:
Iceberg A-68, as it’s called, calved from Antarctica’s Larsen C Ice Shelf on July 12, 2017. Weighing about a trillion tons and featuring a surface area of 2,240 square miles (5,800 square kilometers), the iceberg is about the size of Delaware, or about four times the size of London, England. It’s been drifting away from the area for months now, slowly disintegrating into smaller and smaller bits (and spawning treacherous many icebergs in the process). For thousands of years, this chunk of ice rested above the seafloor, but it’s gone now, and scientists are eager to explore the mysterious world underneath.

ANTARCTICA IS IN THE NEWS : DIAMONDS and PRINCE HARRY
The other day I was listening to a talk radio show and I heard that we are suffering from Global Warming but that a new Ice Age may be coming fast. I read about Prince Harry and a team of veterans who've experienced disabilities making it to the South Pole. I read about scientists continuing to look for evidence of ancient life forms - maybe microbes - beneath thick sheets of ice and about the breaking of ice into floating mountains the size of whole states.
What is happening with Antarctica?
The possible discover of DIAMONDS could send explorers of a different kind to that continent.
FOX NEWS : SPARKLING DISCOVERY
The news is that a mineral rock called kimberlites has been detected.
TODAY : PRINCE HARRY AND TEAM EVACUATED TODAY AFTER REACHING POLE DEC 14th

ANTARCTIC WHALE SKELETON and NINE NEW DEEP SEA SPECIES
LA TIMES SCIENCE : First Antarctic whale skeleton turns up nine new deep-sea species link to full article and pictures! By Amina Khan
"Whale falls — when the body of a deceased whale sinks to the bottom of the ocean — can become an oasis rich in resources for deep-sea life. That ecosystem develops in stages: First, swimmers such as sharks, hagfish and crustaceans will gnaw off the flesh. Next, other hungry critters will break down the remaining soft tissues. Then chemical-consuming microorganisms will break down the waste sulfide left by previous generations, a process that may take decades."

GATEWAY ANTARTICA : LINK TO THE FISH THAT LIVE ON THE ICE ABOVE THE SURFACE OF THE SEA
This is a new one for me. I knew that there were some fish that could survive for a short while half in and out of the water, but I never thought I would see fish that are living on the top of the ice. Go to the ADAPTIONS TO THE COLD PAGE and see the picture for yourself!
The Antartic temperatures require great adaptations. THESE SURFACE DWELLING FISH HAVE BLOOD THAT'S LIKE ANTIFREEZE!

NSIDC NATIONAL SNOW AND ICE DATA CENTER
It's way too hot! Here in the Northern Hemisphere it is SUMMER and there are some overwhelming heat waves happening right now... But in the SOUTHERN hemisphere, and the SOUTHERN ocean, the ANTARCTIC it is winter, dark, and colder than ever. Here is a very scientific site that looks at snow and ice and weather...
"Arctic SEA ICE reflects sunlight, keeping the polar regions cool and moderating global climate. According to scientific measurements, Arctic sea ice has declined dramatically over at least the past thirty years, with the most extreme decline seen in the summer melt season."
