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.

FORBES _ FRESHWAER FOUND UNDER OCEAN FLOOR

Massive reserves of “freshwater” are buried beneath the seabed on continental shelves around the world, including off Australia, China, North America and South Africa.

This is the conclusion of a new study by a team of Australian scientists that appears in this week’s issue of the journal, Nature.

 

Based on an analysis of seafloor water studies conducted for oil and gas exploration purposes, the study showed that an estimated that 500,000 cubic kilometers of low-salinity water is trapped in aquifers under the ocean floor."
