1. At 16 years, Greta Thunberg Climate Change Activist is Nominated for Nobel Peace Prize
A British-led scientific mission to document changes taking place beneath the Indian Ocean has broadcast its first live, television-quality video transmission from a two-person submersible. Monsoon storms and fierce underwater currents continued to present a challenge at greater depths as scientific work began in earnest on Tuesday off Seychelles. The Associated Press has successfully broadcast the first multi-camera live signal in full broadcast quality from manned submersibles using optical video transmission techniques, in which the pictures transmit through the waves using the blue region of the electromagnetic spectrum.
5. How Shark Trackers Uncovered Illegal Fishing in the Indian Ocean
In April of 2015, researchers headed out to the Chagos Archipelago in the Indian Ocean to service acoustic receivers they had dotted around the archipelago, and to download tag data from the 95 grey reef and silvertip sharks they had tagged a year prior. Little did they know that over the course of 10 days during the previous December, 15 of their tagged individuals had been illegally fished. The Chagos Archipelago, otherwise known as British Indian Ocean Territory, boasts one of the largest marine reserves in the world. The BIOT Marine Protected Area was created in 2010 and comprises 210,040 square miles of marine habitat, including an archipelago of seven atolls, at least 70 islands, and some of the world’s most pristine coral reefs.
7. Ocean Heat Waves Are Threatening Marine Life
When deadly heat waves hit on land, we hear about them. But the oceans can have heat waves, too. They are now happening far more frequently than they did last century and are harming marine life, according to a new study. The study, published Monday in the journal Nature Climate Change, looked at the impact of marine heat waves on the diversity of life in the ocean. From coral reefs to kelp forests to seagrass beds, researchers found that these heat waves were destroying the framework of many ocean ecosystems.
