Is Fukushima Radiation Causing the Epidemic of Dead and Starving Sea Lions In California?

Associated Press reports:

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.




Even the pups that are making it are markedly underweight ….




Rescuers have had to leave the worst of them in an effort to save the strongest ones, she said.




Routine testing of seafood is being done by state and federal agencies  and consumer safety experts are working with NOAA to find the problem.”No link has been established at this time between these sea lion strandings and any potential seafood safety issues,” NOAA said in a statement.

Given that the FDA has refused to test seafood for radiation, we’re not that confident that the government is looking that hard to see if Fukushima fallout is the cause.

Reuters notes:

From the beginning of this year through last Sunday, 948 sea lion pups came ashore in Santa Barbara, Ventura, Los Angeles, Orange and San Diego counties, according to figures from NOAA.


“There really isn’t an oceanographic explanation for what we’re seeing,” Melin said. “We’re looking at disease as a possibility and also at the food supply, and it could be some combination.”

CNN reports:

This is an unprecedented crisis for the species in this state says the Pacific Marine Mammal Center.




“So we are seeing exponentially higher numbers” [Keith Matassa, who runs the Pacific Marine Mammal Center in Laguna Beach said].



When you say off the charts, this is what you’re talking about.

CBS News reported last week:

”They’re very sick,” said Keith Matassa, who runs the Pacific Marine Mammal Center in Laguna Beach. His team is nursing 115 sea lions back to health. “A normal sea lion at this age — 8 to 9 months old — should be around 60, 70 pounds,” said Matassa.

“We’re seeing them come into our center at 20 to 25 pounds, and really they look like walking skeletons.”

AP notes:

Biologists knew last spring that this year’s supply of anchovies and sardines could be limited, Boehm said.


“These two species of fish are an extremely important part of California sea lions’ diets, and females simply may not have been able to nurse their young sufficiently, resulting in abandonment, premature weaning and subsequent strandings,” he said.


Besides anchovies and sardines, sea lions also eat squid and other ocean creatures.

Time reported in April 2011:

Few people want to see the ocean’s anchovy stocks wiped out by radiation either. That’s just the scenario that seemed to be developing, however, when reports coming out of Japan revealed that elevated levels of cesium-137 had been found in anchovies in the waters off Chiba, near Toky0—a direct result of the ongoing crisis at the Fukushima Daiichi power plant.




In the big-fish-eats-little-fish way of the ocean, the radioactive contamination eventually gets passed up the food chain, concentrating in fats which get consumed and stored, until the isotopes finally come to rest in the very largest creature at the top of the food chain ….

Huge die-offs of sardines were also reported in the Chiba area of Japan after Fukushima.

Moreover, the Vancouver Sun reported in January 2012 that 94 per cent of the anchovies and 92 per cent of the sardines sold by the Japanese to Canada contained radioactive cesium. Some of the fish were caught in Japanese coastal waters; but others were made many hundreds of miles away in the open ocean.

(Note: there may be additional reasons for fluctuations in the numbers of anchovies and sardines other than radiation.)

Moreover, radiation from Fukushima was directly deposited into the kelp off the Western coast of North America … especially in Southern California.

Fish that eat the kelp have also gotten exposed to the radiation … as have the animals that eat those fish.

NOAA reports:

Sea lions … feed on the fish that live in kelp forests.

(Images here.)

There are numerous other routes in which the Fukushima radiation could be getting to the sea lion pups.  We noted last year:

A 1955 U.S. government report concluded that the ocean may not adequately dilute radiation from nuclear accidents.


MIT says that seawater which is itself radioactive may begin hitting the West Coast within 5 years.


In 10 years, peak radioactive cesium levels off of the West Coast of North America could be 10 times higher than at the coast of Japan.


As we’ve previously noted, Reuters reports that Alaskan seals are suffering mysterious lesions and hair loss:

Scientists in Alaska are investigating whether local seals are being sickened by radiation from Japan’s crippled Fukushima nuclear plant.


Scores of ring seals have washed up on Alaska’s Arctic coastline since July, suffering or killed by a mysterious disease marked by bleeding lesions on the hind flippers, irritated skin around the nose and eyes and patchy hair loss on the animals’ fur coats.




“We recently received samples of seal tissue from diseased animals captured near St. Lawrence Island with a request to examine the material for radioactivity,” said John Kelley, Professor Emeritus at the Institute of Marine Science at the University of Alaska Fairbanks.


“There is concern expressed by some members of the local communities that there may be some relationship to the Fukushima nuclear reactor’s damage,” he said.

Here’s a picture of one of the injured seals:


We reported yesterday that a new scientific paper shows that the Fukushima radioactive plume contaminated the entire Northern hemisphere during a relatively short period of time ….


Radioactive fish are also being found off the West Coast.


A California-sized island of debris from Japan is also hitting the West Coast.


And West Coast residents have also been exposed to Fukushima radiation from the air.  See this, this and this.

Unfortunately, the nuclear accident is nowhere near contained.  Japanese experts say that Fukushima is currently releasing up to 93 billion becquerels of radioactive cesium into the ocean each day, the reactors have lost containment, and groundwater is flooding into the stricken reactors (delaying clean-up).

And things may get worse for California, instead of better .

a few decades ago there were [no] few sea lions in [LaJolla] because the abalone fishermen depleted the species. F&G put regulations on abalone [and the WW2 DDT worked its way through the system] and the sea lions came back, the white sharks followed. along with sea lions and sharks came the bait fish.. now without any real ecological chain reaction the sea lions are taking a dive [whales are okay though, check out the whales, this is a great year for the whale migration, but who knows?] and that brings up the question. [california spews a lot of untreated sewage into the ocean, and how radioactive is that?]

How much do you get paid to reassure us that one of the listed 10 tops ways to destroy the earth is not destroying the earth?  What would you do if you were earning a couple million dollars a year in an industry that was considered to be a threat to mankind?  Lie about it and buy more stock options? 

Take your child into the pacific lately?  Perhaps you are so convinced that a nuclear disaster with nonstop run off into the ocean is like pissing in the wind that you live in the harbor and bath in the sea water. 

Kevin Matthews · Editor in Chief at ArchitectureWeek

Despite vacuous assurances from public authorities in the U.S., Canada, and Japan, watch for radiation to concentrate up the food chain, for instance in wild Pacific Salmon, some of which circle the north Pacific and return eastward following the same currents that are concentrating the unprecedented ocean radiation release from the Fukushima disaster.

Who is monitoring for this? How fast do the salmon travel relative to the pace of the Japan Current?  April 4, 2012 at 7:48am - Sellafield - Plutonium generation plant and the subsequent global implications.

Shark population is in a sharp decline.

If only radiation were a measurable quantity that could be easily detected and measured with devices found in any college science department we would have an answer to this mystery.
But since nuclear radiation is just a bunch of weird rays and beams and shit that nobody understands or can quantify, its best to just jump to conclusions.
BTW, before Fukushima the eco-nazis were blaming dead sea critters on US Navy sonar.

The European Commission has attributed the sudden increase in loan mortality to Fukushima radiation.
As expected the pollution first struck EU member states in the Mediterranean, part of the EU that lies in closest proximity to Japan.
GW was called to help.

Background radiation is every where. Did you know know how much radiation is in a banana?

"Bananas are a natural source of radioactive isotopes. True, there's not much in one banana. But enough, according to Nuclear Threat Initiative - a security-minded think tank - for a few bananas to trigger radiation sensors used at US ports to detect smuggled nuclear material. "

And I probably know more about science than you do. And I already know your next move is to post links to some website about how anyone who disagrees with you on a forum is a government disinformation operative. Everyone knows your tired old schtick already.

I have a link for ya.  You will be pleased to know that you are going to be proven wrong.

Fukushima Fallout - Bird die off.

Precipitation on the Pacific coast is ocean water.  Do you think the govt is going to tell us that we are in danger of exposure?  We'd sue until the men and women who reap vast sums of money from the development of this fuel were living in the park with the people who have lost their homes thanks to the banking industries reckless disregard for responsible business practice.

Radiation biologist speaks at UC San Francisco on Chernobyl and her findings.


Japan nuclear crisis: a 'race against time', says IAEA Yukiya Amano, the head of the UN's nuclear watchdog, has said that Japan's battle to stabilise a crippled nuclear plant was "a race against time".

But nothing matters when you are not the one with Radiation burn, eh?  It's ~all about you~.

steveo77's picture

ya, the old banana freaking bullshit.   Classic lie holding an element of truth.   But your potassium level in the body stays constant, so you dont increase your natural dos by eating bananas.

Another pro-nuke troll did an interesting lie, equating the dose you get from sleeping next to someone.     This post debunks that lie,


We found that the pro-nuke liar was exaggerating by 625,500 %.    Wow.  

George Washington's picture

The EPA notes, in contrast:

The human body is born with potassium-40 [the type of radiation found in bananas]] in its tissues and it is the
most common radionuclide in human tissues and in food. We evolved
in the presence of potassium-40 and our bodies have well-developed
repair mechanisms to respond to its effects. The concentration
of potassium-40 in the human body is constant and not affected
by concentrations in the environment.

Agenda 21 - Said to be enforcing life to prevent continuation of global warming has nothing to say about this disaster.  United Nations has given little to fight this crisis, even after being formally requested to assist in containment of the fall out.

This should be telling for those who support Agenda 21.  This is a scam in order to put into place a global govt which will reduce the population to those who are the owners of industries and those who can work diligently because nothing else matters to these psychopaths. 

Feel fleeced? Feel lied to?  Feel unsafe?  You should be.  We are in serious trouble.

Thanks for covering this Geo, we've been seeing some coverage locally on LA TV:

At the same time this is happening on the West Coast, Manatees and other marine creatures are sick in numbers in the Gulf and East Coasts of Fl.

Two "unusual mortality events" thousands of miles away at the same time.

Gulf coast problems are from the Oil Well explosion.  They government covered up the dispersents that were being used.  The dispersents were banned in the UK.  Why did they use them here?

Red tide is nasty, grew up with it as a common occurance in my stretch of coast. I do not see the connection to possible radiation sickness in the sea loins.

Old Poor Richard's picture

So I'm guessing that of these 100's of sea lions currently in rehab, none of them are showing any signs of radiation.  If they were radioactive, we'd have heard about it.

Wonder if it's global warming?  Nah, there's no such thing.

@ George.

No, surely the fucking scientist who does research on: "Factors leading to possibility of transport of radionuclides fromthe former Amchitka Island Underground Nuclear Tests", "Temporal variations of natural and anthropogenic radionuclides in sea otter skull tissue in the North Pacific Ocean.", "An assessment of the reported leakage of anthropogenic radionuclides from the underground nucear test sites at Amchitka Island, Alaska, USA to the surface environment" wouldn't tell the truth right?


Jesus George you're such an infuriating hack. Which way will you dodge now? Here's some advice, DO SOME FUCKING RESEARCH before you copy paste more outdated shit.

There's bad news and more bad news in that 93 billion Bq figure. 

At 440 Tbq/Eq, that would be about 36 milligrams of Cs-137 chloride. It's unbelievably deadly hot stuff. 

A back-of-the-envelope calculation back in April 2011 determined that the reactor complex had about two metric tons of Cs-137 on hand, based on how long it had been operating and its power output. Assumption was that all the spent fuel is still in storage there, which is apparently true. So that's the first bad news. 

The other bad news I have is that I seriously doubt that they can keep the leakage level down to 36 milligrams per day. We still don't know how much of the spent fuel is in intact fuel assemblies sealed in zirconium tubes, and how much of it is in the form of wild corium furioulsy spewing high level radwaste into the atmosphere and ocean. 

The other-other bad news is that, here in the US, we have forty or so plants of the exact same design, the GE Mark 1 boiling water reactor. One of them almost failed in a flood at Fort Calhoun Nebraska in 2011.

Knowing this, do you really think there will ever be any formal confirmation by the USGOV that Fukushima is the cause?

Knowing this, do you really think there will ever be any formal confirmation by the USGOV that Fukushima is destroying the Pacific food chain?

However wrong this may be, this is the world within which we now live.

I stopped eating anything out of the Pacific two years ago.

You probably cannot tell where a fish came from unless you pulled it off your hook.  You have to stop eating fish entirely except for what you catch.  Also fish meal and other fish by products.  So if everyone stops eating fish,  the price of fish falls.  Fisherman go out of business.  Radioactive fish start multiplying and refill the oceans. In a few centuries they will not be radioactive any more.  Then you can start fishing for them again.  Last I looked, the Pacific ocean  is connected to the Indian, Arctic, and Atlantic oceans.

Nice display of anthropocentrism. I find it entertaining when humans blow smoke up their own ass to make themselves feel important.

Here's the thing: wild animals are actually free to the extent that they live upon the land and what it can provide and they are not dependent upon: utilities, agriculture, transportation systems, government, or any of the other dependencies that you require to exist (unless you are one of those rare souls who can actually fend for yourself).

As a species, we are no better than yeast, and will end up the same way yeast end up when given a plentiful supply of energy: dead from the toxic byproducts of their own waste.

Technology will kill the human race, one way or the other.

Reci's picture

 It's not so much about the "Technology" as it is about the irresponsible nature of implementation and management with the primary focus being cost vs safety.  Furthermore, the dismantling of regulation agencies and silencing of environmental groups for the financial benefit of corporate owners and their crony political cohorts has created a minefield of potential disasters that are often easier to cover up than try to prevent (at least in the minds of the number crunchers who are calculating the odds of disaster vs their lost profits to implement a response ie. tsunami).

 The politicians prefer disasters like "Fuki" since you can't really perceive the entirety of the damage done which is why they added additional toxins (some say worse) to the Gulf oil spill as it helped hide the visible aspects of damaged caused by a poorly maintained system of controls.  Unfortunately for the planet, humans prefer to adopt the feel good nature of altered perceptions rather than the harshness of reality which is needed to prevent and solve these problems before they become unmitigable disasters.

In regards to these seals, I think Seaworld should simply euthanize the majority of the animals that are suffering as I don't see the long term benefit to nursing these animals back through a long painful recovery only to toss them back in the radiated Pacific for another chance at a slow miserable death from radiation sickness.  Then again, the corporate owned media can use these Seaworld "releases" as a way to further the perception that everything is fine and functioning normal in the sea as it is on land so I'm sure TPTB are throwing in a few sponsorship dollars for the "recuperation" of some animals to use as symbollic restoration of the environment.

I'm taking the next rapture out ! Geeze,it's all booked.

After Banda Ache tsunami,Fukusima should have been bolsterred at the least.

Reading FDA/USDA refuse to test sardines/anchovies for radiation one must assume contamination.

I don't think the current seal pup endemic is radiation cuased though possibly closer related to pacific garbage gyre plastic/phenal buildup in the seal feed sources.

Irony is today saw report touting quite large fish populations this year in eastern pacific -who is correct ? Classic misinformation programme ? expect the worst !

Curiously,we were looking to pacific NW to live.Now what ?

This story is most likely intended to promote the closing of Nuke plants. They have already been closed in Japan. Big Oil has been trying to shut them since 'The China Syndrome' was produced. Then, shortly after that, 3 Mile Island had a 'mishap'. 

BigInJapan's picture

Not that I don't think about shit from Fukushima but given that there's a fucking sea-lion on every dock in California, I am inclined to think that this is nature taking care of the problem. They shouild be killing those things and feeding them to the prisoners, anyway.

Stop crying, FFS.

"Coming up on Zero Hedge: Could you possibly be falling for George Washington's clickbait?"

Reci's picture

Quite ironic how you view any large animal population other than humans as some kind of nuisance then when they begin to die from an unhealthy environment unquestionably contributed by's "nature taking care of the problem" thus removing accountability from those humans.  We get it, you're a self-absorbed species centric person with an inflated sense of being and purpose.  You're not unique unfortunately by a long shot.  You think about animals like the 1% think about the middle class and below.  I hope you maintain that attitude as your environment begins to suffer degradation from the surrounding macro environment and/or when someone's disregard for your healthy environment (like a "natural gasser") causes you to get sick enough to allow "nature" to do it's thing.

It doesn't necessarily matter that this problem is directly caused by the Fuki radiation or it is an ancillary contributor.  When large groups of animals that live in an environment show increasing evidence of flesh damage including tumors on most of the sea turtles, then I think you can rationally conclude that it's the nature of humans and not the nature of the planet that is the source of the problem.  All in all, it doesn't really matter as things will only get radically worse as the human population grows until the effects of our "nature" begin to kill us off too but I'm sick and tired of all the deniers who require unquestionable proof and direct evidence about things which have likely and logical conclusions involving multiple contributory factors but will pronounce unquestionably the existence of an involved God on the measly evidence of faith.  I'm not saying you're one of the dedicated religious but I'm just pointing out the hypocrisy of evidence that most people require for things that they want to believe vs. the things that they don't want to believe when objectively it should be the same amount.

Alright you morons it works like this:

Copy pasted from George's "article":

"Scientists in Alaska are investigating whether local seals are being sickened by radiation from Japan’s crippled Fukushima nuclear plant.

Read: cashing in.


Scores of ring seals have washed up on Alaska’s Arctic coastline since July, suffering or killed by a mysterious disease marked by bleeding lesions on the hind flippers, irritated skin around the nose and eyes and patchy hair loss on the animals’ fur coats.

Scores? Nice word selection. How many EXACTLY. You're scientists, right, so you have EXACT FIGURES on how many you've found. No? Whaaaaa?

“We recently received samples of seal tissue from diseased animals captured near St. Lawrence Island with a request to examine the material for radioactivity,” said John Kelley, Professor Emeritus at the Institute of Marine Science at the University of Alaska Fairbanks.

 OK fuckwits, this study took place when?

So I go Googling for the info that George obviously missed in his cut/paste journalism. His link above took me to a dead Yahoo News link. Convenient. I then found the original Reuters article dated December 27,2011.

"The results of the tests would not be available for "several weeks," Kelley said

Well I don't know about you but I can't find ANY test results is a search for "John Kelley, Professor Emeritus at the Institute of Marine Science at the University of Alaska Fairbanks. seal tissue test results"


So, Fuck all y'all who downvoted me.

BigInJapan's picture

But wait! There's more! Err... less! said in February of 2012:

"Back in October, roughly 600 Pacific walruses turned up infected with the disease at Point Lay in Northwest Alaska, while a few months later in December, more than 100 ringed seals living off the coast of Alaska also turned up seriously injured or dead as a result of the disease. At that time, scientists sent in tissue samples from the affected animals to labs in both the U.S. and Canada, but the cause could not be determined." 

Can you fit all that in your mouth there? Yeah, suck it...

eeehm did it ever occur to you that the immune system of mammals is damaged in case of contamination with radio isotopes?
especially Strontium 90.


I'll spell it out for you ok? since you're obviously thickheaded:

another example: the nuclear waste plant in Sellafield, UK belched out a HUGE amount of Radon isotopes. no problem, right, it's naturally occurring. Well not in these quantities. it's even visible with the naked eye:
it decays into Polonium and eventually into Lead (which is obviously toxic, regardless of being a stable element).

the Irish have now objected to the goings on (what else are they not telling us) at Sellafield, they're in a treaty that allows them to.

meanwhile all the EURDEP radiation monitoring is turned OFF, when this hit the mainland.

because that's what they do. they stop measuring once it gets too much.
got it now?

During WWII the US inacted the "Office of Censorship" charged with monitoring the flow of information due to the "war".  (Interesting reading on it in wikipedia)  Anyway, it was said it was "out of business" at the conclusion of hostilities, but I seriously doubt the freedoms the leaders acquired during it's operation would voluntarily be discarded, and their activities have only been much better refined and implimented.

The players are already being chosen for the next game when the recess bell rings, and any negotiations between the captains will only be allowed by the folks holding the debts of the players being held by contract in their league.  Knowledge of these schemes will never be allowed to surface, but rest assured, the tests of the sea lions and other sea life have already been performed and the information is fully there and available, but only on a "need to know" basis.  imho.

Did you spot the selective reporting in the April 2012 newspaper articles?

ABC News article states

"Researchers at California State University, Long Beach  found that the kelp contained radioactive iodine, cesium, xenon and other particles"

The SFGate article only says

"Kelp off California was contaminated with short-lived radioisotopes a month after Japan's Fukushima Dai-ichi nuclear plant accident"

and specifically

"Iodine 131 "has an eight-day half-life, so it's pretty much all gone," Manley said."

Why didn't they mention the caesium and xenon? And what were the "other particles"?

I smell a whitewash.
