The “Sea Monster” That Won’t Go Away–NEP20b, AKA The Blob of Warm Ocean Water

By on • ( 0 )

The phenomenon of a patch of abnormally warm water off the west coast of North America gained notoriety in 2014, when the first such “Blob” was spotted and given that name, after the horror movie creature that devoured everything in its path. That first Blob lasted years, from 2013 to 2016. It has been blamed for slicing some forage fish populations in half; starving seabirds; triggering a collapse in cod; shifting tuna as far north as Alaska; pushing whales into the path of crab fishing lines and ships; and allowing exotics, including glowing tropical sea pickles, to arrive in northern waters.

Mass Die-Offs Continue to Threaten Marine Life

Balmy temperatures can lead to conditions perfect for the spread of infectious diseases, Sanderson said. When sea ice melts too early in the season, seal pups must enter the water before they are ready to be weaned, leaving them weaker and more vulnerable to disease. Vanishing sea ice also means that seals and sea lions in cold regions will have less space to emerge from the water to rest, breed, or escape predators, forcing them to crowd more tightly together.

New report connects ocean changes with human activities on land.

The report makes clear that to protect the ocean, we must first reduce our dependence on fossil fuels. But we must also reduce ocean stress, caused by overfishing and pollution, so the ocean is healthy enough to weather the changes already underway.

“The bottom line is that we need the ocean. And right now, the ocean needs us,” said Julie Packard, executive director of the Aquarium. “It’s not too late to take courageous climate action and safeguard the ocean from further damage.” 

A Sea Bird Dead Zone

In a study published Wednesday in the journal PLOS ONE, a group of scientists from various state and federal agencies, universities and bird rescue organizations documented the die-off and concluded from the data that it was caused by a record-breaking ocean heat wave in 2014 through 2016 that triggered systemic changes throughout the ocean ecosystem.

“Marine animals are disappearing at double the rate of land-based species”

…marine animals like fish, crabs and lobster are already more likely to be living near the threshold of life-threatening temperatures, and because in the ocean, there are fewer places to hide from extreme heat, said Malin Pinsky, lead author of a new study published Wednesday in the journal Nature.

“These results are stunning, in part because the impacts of climate change on ocean life were virtually ignored just a decade ago,” said Pinsky, an ocean researcher at Rutgers University. The study took a close look at cold-blooded marine species whose body temperatures are dependent on their surroundings.
