Atlantic

First spotted in the Atlantic Ocean off Florida in the 1980s, they later spread across the Caribbean, reshuffling coral reefs and other ecosystems by feasting on fish unfamiliar with the voracious predator.

While ocean currents that flow north—such as the South Equatorial Current—and the freshwater plume created by the Amazon River hampered the spread of the invasive species, scientists predicted it was just a matter of time before it moved into Brazilian waters.

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.

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.

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.

“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.
