San Franciso Bay Area Dungeness crabber Captain John Mellor
“We’re like the Giants. We’re your hometown team,” said Captain John Mellor last week as he described the San Francisco Bay Dungeness crab fishing fleet. Capt. Mellor’s pride in his work as a crabber is paired with a love for what he does. But, his feelings are mixed with fear for the future. A West-Coast wide toxic algae bloom shut down the fishery last year, leaving him out of work for five months. Fishermen and researchers are also worried that ocean acidification could represent a looming threat to the fishery that could cause future fishing disruptions.

When you think of walruses, you may picture their tusks—the huge pinniped’s most familiar characteristic. But there is so much more to these “elephants of the sea”! Here are some less-obvious facts about these ice-dwelling creatures.
1. Biologists classify the walrus as a carnivore, or meat eater, which puts the animal in the same broad category as wolves, foxes and lions.
2. The polar bear, weighing as much as 1,200 pounds, is often touted as North America’s largest terrestrial carnivore. But it’s a mere wisp compared to the ocean-going male walrus, which can tip the scales in excess of 3,700 pounds.
2016 hasn’t been a good year for the West Coast Dungeness crab fishery. The fishing season that typically spans the winter months – worth $212 million in 2014 – got significantly delayed this year when Dungeness crabs tested high for domoic acid, which sickens humans, and managers shut down the fishery. The crabs had fed heartily on a giant toxic bloom of Pseudonitschia algae, which produce domoic acid, and which were thriving in an unusually warm body of water stalled offshore, affectionately called “the blob.” The bloom also shut down other West Coast shellfish fisheries, too. The lost harvests equal lost income for West Coast communities. San Francisco Bay Area crabber John Mellor says, “If crabs were to disappear from the picture, I think it would be the end of my fishing career at this point.”
The growing tide of ocean pollution is a problem for sea turtles that ingest plastic, sea birds that get tangled in fishing lines and marine mammals that wash ashore with belly’s full of trash.
I’m grateful to the Senate for passing the U.S. Marine Debris Research, Prevention and Reduction Act of 2006, which authorized the creation of the Marine Debris Program (MDP) within the National Oceanic and Atmospheric Administration (NOAA). The NOAA MDP has been instrumental in informing and catalyzing marine debris research and solutions in the United States and abroad.
Thankfully, the leak has been secured, and clean-up efforts are underway, as a result of NOAA and the Coast Guard’s immediate response. There are 52,000 boreholes drilled into the Gulfseafloor, the result of a century-old search for oil and gas. Much of the time, offshore oil production proceeds relatively safely and without much public interest, but when things go wrong in the Gulf of Mexico, they can really go wrong.
But Shell still has one lease remaining in the Chukchi Sea, along with leases in the Beaufort Sea off northern Alaska. What’s more, the Obama Administration is still considering whether to allow the sale of more offshore oil leases in Arctic waters.
