Santa Cruz Sentinel, Aug. 1, 2014: The Marine Mammal Center […] has seen a record-breaking number of patients this year, with 727 admitted through July. In 2013, the center admitted 521 animals. There’s a large number of starving, young sea lions and an algal bloom in Monterey is making adult sea lions sick.
Santa Cruz Sentinel, July 23, 2014: ”We’ve had a record number this year in sea lion admits,” [Marine Mammal Center spokeswoman Laura Sherr] said. The majority of the ailing sea lions have been impacted by a neurological disease caused by large blooms of domoic acid, which is produced by algae. She said the center has also rescued an increasing number of stranded sea lion pups. […]

– Over 50 dead seals, sea lions, whales, walrus recently stranded in Alaska — Dozens of seals suffering from baldness, skin sores — Experts: “Marine transported Fukushima radionuclides… may represent a new stressor to ecosystem” (ENENews, May 6, 2014):
Poster for Alaska Marine Science Symposium, Jan. 20, 2014: Based on modeled radionuclide concentrations the dose to Northern Pinnipeds on ice was less than the ERICA risk assessment no-effects level of 10 uGy/hr with the following caveats: 1) Source terms for the Fukushima nuclear accident release vary greatly creating uncertainty in the models. 2) Knowledge gaps exist on extrapolating radiation dose to marine mammals. 3) Exposure to hot particles was not addressed. 4) Cannot rule out that increased radiological exposure in combination with a mixture of other contaminants represented an immunotoxic and thyroid disease risk during the period the animals were living on the ice. 5) Ionizing radiation associated risk for skin defects (i.e. epilation, skin lesions) due to contact and external exposure can also not be excluded. *Marine transported Fukushima radionuclides entering the Bering and Chukchi Seas in the future may represent a new stressor to the ecosystem.
– Alarm as record numbers of seals & sea lions ‘starving to death’ along California coast — “It’s just spiked… calls started coming nonstop” — “So many unhealthy… washing ashore” — “Extremely complex issue… multitude of factors in play” — “Definitely a mystery, we’re hoping it’s not the new norm” (ENENews, May 4, 2014):
Orange County Register, May 2, 2014: Sea lions are […] washing ashore, many of them pups dehydrated, malnourished and on the brink of death. The year started off quieter than last year, and the Pacific Marine Mammal Center’s director of development, Melissa Sciacca, thought they were in the clear – until about a month ago, when the calls started coming in nonstop. […] “We thought it was going to be a nice calm year; in the last month it’s just spiked,” she said. “The rescues just keep coming in at a steady pace.” It’s the second year stranded sea lions have been reported in alarming numbers. […] Last year, scientists tested for radioactivity, and it was determined that wasn’t the cause, and infectious disease was also ruled out.

Marine researchers are baffled about the reason for the anchovy explosion. […]
– Starving, Dying Sea Lions Washing Up On Southland Beaches (CBS News):
– Starving sea lion pups fill Calif. rescue centers (AP, March 29, 2013):
LOS ANGELES (AP) — Hundreds of starving sea lion pups are washing up on beaches from San Diego to Santa Barbara, overwhelming rescue centers and leaving scientists scrambling to figure out why.
At island rookeries off the Southern California coast, 45 percent of the pups born in June have died, said Sharon Melin, a wildlife biologist for the National Marine Fisheries Service based in Seattle. Normally, less than one-third of the pups would die.
It’s gotten so bad in the past two weeks that the National Oceanic and Atmospheric Administration declared an “unusual mortality event.” That will allow more scientists to join the search for the cause, Melin said.
Pups are normally weaned from their mothers in April.
Even the pups that are making it are markedly underweight, Melin said.
The most recent pups weighed at the breeding area on San Miguel Island were around 37 pounds, Melin said. They should weigh between 55 and 59 pounds by now, she said.
