SARGASSO SEA, NORTH ATLANTIC OCEAN (March 11th, 2022)

Often referred to as “the floating golden rainforest of the Atlantic Ocean”, the Sargasso Sea covers an impressive two million square miles of water. It has no land boundaries: rather, the area of the Sargasso Sea is defined by the whirling grasp of major currents within the North Atlantic Gyre. Vast mats of sun-soaked, free-floating yellow Sargassum seaweed bob at the surface under distinctively calm air. 
 
 
The Sargasso Sea is a high seas ecosystem – it lies outside of the boundaries of any country. The high seas make up more than 60% of the ocean and while they possess deeply important biological diversity, they remain some of the least protected places on the planet.…

Cashes Ledge: the Gem of New England

Led by Dr. Sylvia Earle, the Mission Blue team recently returned from a Hope Spot Expedition to Cashes Ledge, a pristine biological hotspot off the coast of New England. It contains Ammen Rock, a peak so tall that it disrupts the Gulf of Maine current, creating massive upwellings of cold nutrient-rich water that fuels an explosion of life from plankton and squid to mackerel, tunas, billfish, sharks, seabirds and a high diversity of marine mammals. The area is home to the largest cold water kelp forest on the Atlantic seaboard and provides a nursery for important New England fish species like cod, pollock, Atlantic halibut, and white hake. Check out the map for a better sense where the Cashes Ledge is located.…

The Deepwater Horizon Catastrophe 5 Years On

No one missed the Deepwater Horizon disaster. People missed the recent oil spill in Bangladesh. But the world witnessed Deepwater Horizon. Millions of gallons of oil flooded the Gulf of Mexico everyday — for 87 days. The biggest accidental oil spill ever. Five years later the effects of the Deepwater Horizon blowout still endure. A new study confirms a massive undersea oil mat near the unlucky oil well — Macondo 252 — that blew on April 20th, 2010. Considering this tar mat is the size of Rhode Island, the Gulf is clearly still feeling the affects of the catastrophe five years on. Gulf sea turtles stranding more frequently, dolphins killed, observed oil slicks hundreds of kilometers in length after the well was “capped” — a depressing list of unknown length.…
