Populations of tiger sharks in Atlantic and Indo-Pacific found to have evolved separately

Researchers have discovered that the tiger sharks in the Atlantic are genetically different from the ones in the Indo-Pacific Ocean, according to a study published in the Journal of Heredity on 10 August 2021.

According to co-author Professor Mahmood Shivji, director of the Save Our Seas' Shark Research Centre, the two populations had not intermingled to reproduce for a long time. “This long-term separation between Atlantic and Indo-Pacific tiger sharks has resulted in them developing into separate populations, each with its own unique genetic diversity.”

Warming Atlantic drives right whales towards extinction

During the past decade, the Northwest Atlantic’s Gulf of Maine and western Scotian Shelf have been warming more rapidly than most of the global ocean

As this region has warmed, changes in ocean circulation have driven the critically endangered North Atlantic right whale population from its traditional and protected habitat, exposing the animals to more lethal ship strikes, disastrous commercial fishing entanglements and greatly reduced calving rates.

Admiral Graf von Spee's famous flagship, SMS Scharnhorst. The wreck has now been located off the Falkland Islands

Wreck of Famed WWI Heavy Cruiser SMS Scharnhorst Discovered off Falklands

The wreck of the German battlecruiser SMS Scharnhorst, sunk by the Royal Navy during the First World War with the loss of all her crew and Admiral Graf von Spee has been found in the South Atlantic. SMS Scharnhorst, the flagship of the East Asia Squadron which was once the scourge of the Royal Navy, went down with most of the rest of the formation on December 8, 1914, in the Battle of the Falkland Islands.

The battlecruiser sank on Dec. 8, 1914, with more than 800 crew members on board, including German Adm. Maximilian Graf von Spee.

WW1 cruiser HMS Hampshire to be surveyed in 3D

The 10,850-ton armoured cruiser HMS Hampshire departed Scapa Flow in Orkney on 5 June 1916 on a voyage around the north cape of Norway to the port of Archangel in northern Russia. She was carrying Lord Kitchener, the Secretary of State for War, and his staff to Russia to discuss mutual war aims and strategy.

Proposed expansion of Monitor Marine Sanctuary met with opposition

Now limited to the area off Cape Hatteras where the Civil War ironclad USS Monitor sank in 1862, the proposal is to extend NOAA’s Monitor National Marine Sanctuary to include ships sunk in what is known as “Torpedo Alley.” About 1,200 U.S. servicemen lost their lives in shipwrecks off the North Carolina coast – about half the total who died at Pearl Harbor.

HMS Hood was the last battlecruiser built for the Royal Navy.

Bell from WW2 battleship HMS Hood recovered

The bell was successfully recovered the 7th of August. Mr. Allen's team led the operation using his yacht M/Y Octopus, which is equipped with a state-of-the-art remotely operated vehicle (ROV). Once restored, the bell will respectfully serve as a tangible and fitting memorial for the 1,415 lives lost when the Bismarck sunk the ship in the North Atlantic.

South Georgia

South Georgia is the most well-known of the Falkland Islands, also called Islas Malvinas. It lies nearly at the end of the world in the Southern Atlantic Ocean. To find this place on the map, draw an equilateral triangle with one vertex on Cape Horn and another on the Antarctic Peninsula. The third vertex in the east is our destination.

The Venus flytrap sea anemone (Actinoscyphia aurelia) is a large sea anemone that superficially resembles a Venus flytrap. It closes its tentacles to capture prey or to protect itself. It is a deep ocean species.

Ancient Deep-Sea Coral Reefs Serve as Underwater ‘Islands’ in the Gulf Stream

“We discovered that a number of animals thought to be rare are common around the corals, documented many animals outside of their previously known ranges, and discovered species new to science,” NOAA zoologist Martha Nizinski said.
