The ship that tried to warn the Titanic has been found

The British merchant steamship SS Mesaba sent a warning radio message to the Titanic on April 15, 1912 while crossing the Atlantic. The message was received by the Titanic – which was advertised as unsinkable – but did not reach the main control centre of the vessel.

Later that night, the supposedly unsinkable Titanic hit an iceberg and sank on her maiden voyage, taking 1,500 lives and becoming the world’s most infamous shipwreck.

Ban on fishing of mako sharks reached at meeting

At the annual meeting of the International Commission for the Conservation of Atlantic Tunas (ICCAT) last week, North Atlantic fishing nations have pledged to ban catches of the shortfin mako shark.

The efforts to secure the ban was led by the UK, Canada and Senegal. The move means that the countries agreed to end overfishing immediately and to gradually achieve biomass levels that were enough to support maximum sustainable yield by 2070 for the species, according to an article in The Guardian.

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.

Outside my window, the South Atlantic lay unbroken—an azure expanse of ocean below and sky above. Three hours after passing the Namibian coast, a lone patch of clouds appeared on the horizon. As we approached, I could just discern patches of green peering through. Atop a narrow ridge, a tiny strip of runway appeared, the sheer drops at each end plummeting to the sea.

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.

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.
