Newly discovered ocean plume could be major source of iron
Scientists recently discovered a “vast plume of iron and other micronutrients” flowing from hydrothermal vents in the South Atlantic Ocean. The discovery of a new major source of iron may force scientists to reevaluate just how much iron hydrothermal vents contribute and the overall abundance of iron in the oceans. Iron is crucial to life in the oceans and is known to contribute to phytoplankton blooms, which can have an impact on how much carbon dioxide the ocean can absorb. The researchers involved in this study will now work to determine how much iron is being released and how much of that makes it all the way to the surface.
Minke whales tagged and tracked in world first
For the first time ever, scientists have tagged and tracked dwarf minke whales. Four whales were tagged in the northern Great Barrier Reef last month. The whales spend a few weeks in near the GBR during the cold winter months and researchers are now hoping to learn where they go next. In only 30 days, one of the whales had already traveled almost 3,000km!
The $20 Trillion Reason Why Richard Branson Wants to Save Sharks
Richard Branson, founder of the Virgin Group, is committed to saving sharks. In this great piece he wrote for TakePart, he discusses why sharks are worth so much and what he is doing to help. If you’ve seen Sharkwater (by Rob Stewart) you’ll probably agree with Branson. “The ocean sustains life on our planet,” he writes, and without the ocean’s apex predators, it would quickly change. Read his whole post to find out how you can get involved in shark conservation.
