Kaikoura quake: Oh no, not the seals!

I’m in absolute grief about this. This is one of my favourite places in New Zealand

Famous seal breeding ground destroyed by quake
Pups from the Ohau Point seal colony frolicking beneath a waterfall. The breeding ground was destroyed in Monday's magnitude 7.5 earthquake.


16 November, 2016


A beloved seal breeding ground near Kaikoura has been destroyed.

Ohau Point is a popular tourist spot due to its thriving seal colony on the jagged rocks by State Highway 1.

Visitors can walk along Ohau Stream Track to a waterfall, where seal pups are often spotted playing in the pool beneath.

The seal breeding ground at Ohau Point, north of Kaikoura, has been destroyed. It is expected a nearby waterfall where seal pups play has also been destroyed.

Massive landslides caused by this week's earthquakes appear to have wiped out the breeding ground along the coast, just weeks before the start of pupping season.

"The majority of that breeding colony is completely gone," Department of Conservation (DOC) ranger Mike Morrissey said.

"It's just rock."

It is likely some seals were killed in the landslides.

It was fortunate timing, however, as many would have been out at sea feeding ahead of pupping season.

It was unlikely there were pups at the waterfall at the time of the earthquake, Morrissey said.

The waterfall was not yet accessible, so it was unclear if it remained intact, but due to the surrounding damage it was unlikely to have survived.

When the seals returned in the coming weeks they would not recognise their home, Morrissey said.

"Those seals generally come back to the area where they were born. They'll go in there and it won't be like anywhere they recognise before, so they'll probably just go and breed on other parts of the coast."

The colony will likely return at some stage, albeit in a different form.

"There's that much damage to the colony there now that if they clear the road they'll probably just tip a lot of that stuff over the edge where it will just create new habitat for them anyhow.

"Once the rocks are settled they'll come back."

There were areas both north and south of Ohau Point where seals could haul themselves out to rest, said DOC marine species and threats manager Ian Angus.

It would take several weeks for the full impact on wildlife to be determined. Blue penguins may also have been affected.

"DOC's immediate priority in the aftermath of the earthquakes is to assist Civil Defence with the recovery effort, including ensuring that structures and tracks are safe."

A group of University of Canterbury students had been studying the seal colony and hoped to use thermal imaging to check the population.

"We're hoping to get up there within the next couple weeks," said scientist Dr Sharyn Goldstein, who is supervising the students.

"Apparently there has been a big landslide, and at this year they're pupping and pregnant so it might have quite an effect."

There are also concerns for the local shearwater population, which live in a colony high in the Kaikoura ranges.

The endangered seabird lives only in Kaikoura where the population is fiercely protected by locals, particularly when they fall from the sky en masse.

DOC has yet to survey the damage to the colony as it can only be reached by helicopter, but it is likely to have been impacted.

"I should imagine from what we can see that there will be quite big effects," Morrissey said.

Mass de-off of seals on California coast

100% death rate of baby seals on California coast

  • None have survived” —
  • Many are starving, suffering from shortage of food in Pacific Ocean”
  • Extremely thin… all sorts of illnesses, infections” “Milkless moms immediately abandoning pups” TV: “The problem is getting worse” (VIDEOS)


22 March, 2016


KION, Mar 17, 2016 (emphasis added): Sea lion moms and pups struggling to survive…  Bay Net, a volunteer group of naturalists, are keeping a watchful eye on them at the Hopkins Marine Station in Pacific Grove. They say the start of the season has been rough. “Some of them have been way too thin to have a healthy birth and have enough milk to feed it,” said Bay Net volunteer Thom Akeman. So far this season 13 pups have been born but none of them have survivedMany seals are underweight and starving, suffering from a shortage of food in the Pacific Ocean… “When they get extremely thin they’re open to all sorts of illnesses and infections,” said [volunteer Marg] Brigadier … The group Harbor Seals of Pacific Grove has been documenting the unusually high rate of dying pups on Facebook.

Chronological updates from Facebook page ‘Harbor Seals of Pacific Grove
  • Jan 25: The first live birth hit Hopkins beach… [The mom] was not nursing it… The pup is very premature and does not appear fully developed…
  • Jan 26: The premature pup from last night was gone. It had been washed away but there was a second premature birth… [The mom] clearly did not have any milk… what concerns us is the overall look of the sealsSo many of the seals appear thin
  • Jan 30: I am sorry to report that our 3rd premature pup was born… This was by far the smallest pup I have ever observed. It did not last longer then [sic] about 5 minutes.
  • Jan 31: [W]e had our 4th premature pup born at Hopkins Beach… [it] died very quickly…
  • Feb 3: We continue to see very thin adult seals
  • Feb 19: Our 5th premature pup was on the Hopkins beach tonight [and] will not survive…
  • Feb 23: Two more premature pups were born… I will spare you the photos… no moms were able to care for them… Saturday, a very young emaciated sea lion pup was discovered at Lovers Point. Washed ashore on the beach were a lot of red crab… if this trend continues in our oceans, many, many more animals will perish
  • Mar 4: [P]remature pup #8 was born… and yesterday morning premature pup #9 was born… Neither of these pups survived and in both cases the moms abandoned them right away… Many of the harbor seals continue to look thin and it becoming painfully clear that we may have lost a portion of our adult seals as they have not returned to the rookery for the past 1 to 2 years… and have been constant fixtures on Hopkins beach… the warming of the oceans and lack of food are taking their toll on the harbor seals as well as, the seal lions and the waterfowl.
  • Mar 8: #10 was born… Once again, this pup was abandoned and is very premature. It will go the way of the 9 pups preceding it… It has already been abandoned…
  • Mar 10: After 10 live births this year where milkless moms immediately abandoned the pups, this mom stayed on Hopkins beach with the 11th live birth of the season… We watched the pup until after 6pm with no successful nursing…
  • Mar 15: I do not think our two pups (#11 with the mom and #12 the abandoned pup) will be with us… I did not see them… Yesterday, pup #12 was in the center of the beach looking very lethargic and pup #11 just never seemed to thrive or put any weight on…
KION transcript, Mar 16, 2016: The problem is getting worse. “Last year was unprecedented for us, we had 359. This year we’re already at 160, and it’s only the middle of March.”

The Death of the Pacific

You’ve got one group of people saying die-offs of marine mammals is due to Fukushima radiation and has got nothing to do with global warming. You’ve got another saying it’s due to the consequences of a warming Pacific (such as algal blooms) and ne'er the twain shall meet apparently.

This is absolutely ludicrous.

Both sides are correct and what we have is a perfect storm of factors coming together at the same time to kill of life in the Pacific.

BREAKING: Dead Seals Test Positive For Radiation/Lukaemia





Many baby seals dying of leukemia-linked disorder along California coast
Blamed for over 1/3 of recent deaths at San Francisco Bay rescue center



29 August, 2015

Of the 46 recently weaned northern elephant seals deaths reported by the San Francisco Bay Area’s Marine Mammal Center between April 20 and August 1 of this year, Disseminated Intravascular Coagulation was listed as a cause of death in 16 — over 1/3 of the total.

U.S. National Library of Medicine (emphasis added): Disseminated intravascular coagulation (DIC) is a serious disorder in which the proteins that control blood clotting become over active… Risk factors for DIC include: Blood transfusion reaction; Cancer, especially certain types of leukemia

DIC “is a pathological process characterized by the widespread activation of the clotting cascadethat results in the formation of blood clots in the small blood vessels throughout the body… and can ultimately lead to multiple organ damage… severe bleeding can occur from various sites. DIC does not occur by itself but only as a complicating factor from another underlying condition, usually in those with a critical illness… DIC can lead to multiorgan failure and widespread bleeding… Causes — DIC can occur in the following conditions: Solid tumors and blood cancers (particularly acute promyelocytic leukemia)… Sepsis or severe infection… Severe allergic or toxic reactions… Giant hemangiomas (Kasabach-Merritt syndrome) [and] Large aortic aneurysms.”

Acute promyelocytic leukemia is a subtype of acute myelogenous leukemia (AML), a cancer of the white blood cells. According to Wikipedia, “ionizing radiation exposure can increase the risk of AML. Survivors of the atomic bombings of Hiroshima and Nagasaki had an increased rate of AML, as did radiologists exposed to high levels of X-rays”

Journal of Intensive Care, 2014: Disseminated intravascular coagulation… with enhanced fibrinolysis is a DIC type usually seen in acute promyelocytic leukemia (APL)… The Scientific Standards Committee… defines DIC as ‘an acquired syndrome [that] can originate from and cause damage to the microvasculature, which if sufficiently severe, can produce organ dysfunction’… problems exist with this definition in terms of not taking into account the type of DIC often seen in acute leukemias (especially acute promyelocytic leukemia)

Journal of Occupational Medicine and Toxicology, 2013: A causal association with leukemia has only been documented to date for ionizing radiation, benzene and treatment with cytostatic drugs… A large number of studies included in the review referred to the effects of ionizing radiation, where new data suggest that the effects of exposure to small doses of ionizing radiation should probably be reevaluated… An update of [the Life Span Study (LSS) of A-Bomb survivors] has shown that exposure to ionizing radiation at doses as low as those usually recorded in occupational settings, leukemia incidence follows a quadratic dose response pattern… Moreover, there is uncertainty on whether the proposed safety limits from the International Commission on Radiological Protection (ICRP) are appropriate, since revised LSS data show that the risk of leukemia remains increased even in groups with low cumulative exposure to radiation

Physics and Radiobiology of Nuclear Medicine (Springer), Jun 29, 2013: Leukemia is one of the most common cancers induced by radiation in humans, accounting for one in five mortalities from radiocarcinogenesis. Risk of leukemia varies with age, with younger persons being more prone to radiocarcinogenesis… Leukemia appears in as early as 2 to 3 years after the exposure, with an average latent period of 5 to 10 years.

The dying Pacific

Just because you don't pay attention it doesn't mean problems go away!!


My feeling is that you can look to ocean acidification and Fukushima in roughly equal measure


"Alarm as record numbers of seals & sea lions starve to death along California coast, and more. Plus, a bonanza of well-meaning but absolutely clueless scientists who, over the past three years, have had no less than a jillion apples fall on their heads, and who still haven't thought it might be due to gravity. A rose is a rose is a rose unless you're a scientist, in which case, you might be thinking it's a walrus."
---Michael Green

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”

San Francisco Chronicle, May 3, 2014: Young seals, sea lions starving in record numbers — Rescuers are scrambling to save a record number of young sea lions and seals along California’s northern and central coast while scientists work to understand why the animals are beaching themselves [...] The emaciated and dehydrated pups are turning up along the 600 miles of coastline from Mendocino to San Luis Obispo monitored by the Marine Mammal Center. Many are too weak to move after washing ashore [...] As of Wednesday, the center had brought in 429 California sea lions, elephant seals, harbor seals and fur seals this year. That’s well above the 291 animals admitted by the same date last year [...] Southern California witnessed an almost 70 percent die-off of young sea lions – those born in summer 2012 – near the Channel Islands, where most American sea lions breed.


Sharon Melin, NOAA biologist: “In 2013, it was only the young animals that tried to do it on their own [...] this year there’s lots of stranding going on, but those are a different age-class of pups.”


Dr. Shawn Johnson, Marine Mammal Center: “The ones we are seeing are basically starving to death [...] It’s definitely a mystery. We’re hoping it’s not the new norm.”


Coastline Pilot, May 1, 2014: “In the last month we’ve seen the rescues spike,” [Pacific Marine Mammal Center's Keith Matassa] said. [...] Researchers are still trying to determine why so many unhealthy sea lions are washing ashore. “The reasons behind the animal strandings are an extremely complex issue,” Matassa said. “Although there is a leading theory that their food source is playing a significant role, there are a multitude of factors that come in to play.”
Starving to death”? 




Gov’t Investigator: Acute hemorrhaging found in dead owls along west coast





  • Mortality event began 8 months after Fukushima explosions
  • In very poor condition… badly emaciated” when arriving in Pacific Northwest from Arctic






ENENews,
3 May, 2014


Campbell River Mirror, Feb. 18, 2014: Guest Speakers in the morning include Dr. Victoria Bowes, avian pathologist, with BC Min. of Agriculture, who will present “The Overwintering Snowy Owl Mortality Investigation


Dr. Victoria Bowes, British Columbia Ministry of Agriculture, June 2013: In the winter of 2011, and again in 2012, an unexpected record number of overwintering Snowy Owls arrived along the southern coast of BC [...] from the high Arctic already in poor body condition, and over a short period of time many of the weakened birds were admitted to local wildlife rehabilitators. Others [...] were found dead or dying. [...] The unanswered question was whether or not there were underlying predisposing factors that made these birds more vulnerable. In January 2013, and again in April, a team of investigators assembled [...] to examine a total of 49 Snowy Owl carcasses [...] the majority of birds in both necropsy sessions were emaciated adult or sub-adult males. An associated finding was carcass pallor accompanied by acute gastric and intestinal hemorrhage [...] terminal intestinal hemorrhage has been recognized as a manifestation of severe physiologic stress [...]

South China Morning Post, Jan. 20, 2013: [...] snowy owls arrive in Vancouver [...] worrying bird welfare experts [...] The owls perch listlessly [...] the second winter in a row that Vancouver has been treated to a visit [...] raising concern among experts who say the owls should normally only visit Vancouver every five or so years [...] some of the birds are badly emaciated.

Rob Hope, Orphaned Wildlife Rehabilitation Society: Some were suffering from asperogillosis, a breathing problem [...] that can be triggered by a weakened immune system or malnutrition. [Owls arrived in] November, earlier than they would normally venture so far south [...] “We have been finding a lot in very poor condition by the time they arrive. They are already in a weakened state.”

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 Mystery’ in California: “Toxic outbreak threatening marine life”


  • Birds falling from sky, sea lions convulsing — “Worst they’ve ever seen”
  • Toxin hits record level, almost 1,000% above gov’t limit
  • Heart lesions, severe shrinking in part of brain, nervous system failure 


ENENews,
3 May, 2014



Santa Cruz Sentinel, May 2, 2014: State health warnings over shellfish, anchovies and sardines are highlighting a marine mystery [...] what’s behind a toxic outbreak threatening marine life? [...] Researchers in the relatively new area of study say the problem is the worst they have ever seen. [Though the] toxin likely has always been part of the ecosystem, the threat appears to be growing. [...] results of late are the highest ever [...] sea lions affected by domoic acid show a severely shrunken hippocampus [and] lesions on the hearts and brains [...] the mystery behind why and when it happens remains largely unsolved [...]


Tenaya Norris, Marine Mammal Center: “We don’t know why these algae produce these toxins [...] They can be in the water and not producing this toxin, and they can be out in the water and raging.”

Raphael Kudela, UCSC marine ecologist: ”There is some evidence that there are more events of larger magnitude [...] it really affects sea otters.”

Rebecca Dmytryk, Wildlife Emergency Services: “We’ve literally had them drop from the sky.”

KION, Apr. 28, 2014: Sea lions found sick and convulsing off Monterey Bay coast [...] now researchers say there may be some indication that humans may also be causing domoic acid to be produced in higher concentrations [...] At least 35 sick sea lions were found stranded on the Monterey Bay. They were convulsing with seizure-like symptoms. [...]

KION, Apr. 14, 2014: [The state] began seeing low levels of demoic acid in the fish in mid-March and 2 days ago noticed it increased to almost 10 times higher than federal regulations.

KSBW, Apr. 30, 2014: Toxic algae blooms killing sea birds, threaten humans — A new health warning has been issued urging people to not eat certain parts of anchovy, sardines, or crab caught in the Monterey Bay. [It's causing seabirds'] nervous systems to fail. [...] the state public health department issued a warning not to eat recreationally harvested shellfish [...] from the Monterey Bay. On Monday, officials issued an update advising consumers not to eat the internal organs of commercially or recreationally caught anchovy, sardines or crab [...] Typically the toxic algae blooms only last a week or two but the latest one has lasted all month [...]
