Oceana’s blog about the latest ocean news, policy and science.
You may not have heard of the dusky shark, a bronze-blue colored species found in warm coastal and pelagic waters around the world. While they may not be as famous as the favored great white or tiger sharks, dusky sharks are just as fascinating: These apex predators can live to be 40 years old, grow to be 12 feet long, and return to their natal regional waters to give birth. Unfortunately, dusky sharks off the Atlantic coast are in trouble.
The public outcry of opposition towards seismic airgun testing has only continued to grow since the Obama administration approved seismic airgun testing along the East Coast earlier this month.

It turns out Oceana isn’t the only one looking into seafood fraud; just this week, a huge seafood fraud bust in Florida was announced. And thanks to President Obama’s pledge to tackle the issue, we may see additional efforts to stop seafood fraud and illegal fishing in the future.
Earlier this week, Oceana launched an expedition to document three seamounts located between the islands of Mallorca, Ibiza, and Formentera, all of which belong to the Balearic Islands. Using an underwater robot known as a remotely operated vehicle (ROV), a team of Oceana marine scientists will capture footage at depths of up to 3,280 feet. The 10-day expedition will allow Oceana to learn about and map areas of ecological importance that are in need of conservation.
- According to a new study, mercury levels in many of the world oceans’ surface waters have tripled due to human activity. Because mercury drains into the ocean from mines, coal-fired plants, and sewage, mercury levels are higher in surface waters compared to the deep ocean. The Guardian

- A team of researchers that’s been monitoring gray whale populations off California for several years say that their numbers are increasing. Marine observers have spotted 431 gray whale mothers and calves so far this year as they make their annual migration to the Arctic. UT San Diego
In recent years, record numbers of barrel jellyfish have swarmed UK waters by the billions. These jellyfish are massive—stretching nearly 3 feet wide with tentacles that can extend for 6 feet. But in a recently released video, a diver off the coast of UK waters swam next to what may be one of the biggest barrel jellyfish ever spotted, according to The Telegraph.
