Sea change: Here’s what’s wrong in the Pacific Ocean

Weird things are happening off the Pacific Coast.

And at the center of the action is a warm-water mass that scientists call “the blob.”

It’s turning the coastal ecosystem on its head. Species are dying along Washington, Oregon and northern California: sea stars, marine birds and sardines, among them.

It started in the fall of 2013 when the Gulf of Alaska’s usual winter storms didn’t show up to cool down the Pacific.

That gave rise to an expanse of warmer water, according to Bill Peterson of the National Oceanic and Atmospheric Administration.

And it has spread. By last summer the blob had consumed the entire North Pacific from California to Canada. A few months later it had touched the West Coast shore. Now it spans 2,000 miles from Baja, Mexico to Alaska, stretching 500 miles wide.

It’s hard to get away from something that big, and while some species are dying, others are behaving strangely.

Tropical plankton are showing up for the first time. Native plankton are breeding much later. Brown pelicans are refusing to mate at all. And toxic algal blooms are spreading rapidly, at times shutting down commercial and recreational fishing.

The blob isn’t responsible for all of the strange happenings, though. The cyclical warm-water weather event El Niño is back on the California coast, and it looks as strong as its last severe episode in 1997. That makes this a double whammy for experts trying to get to the bottom of these habitat changes. And that’s leaving out the climate change variable, which may or may not be related to both events.

Basically, it’s not just a bunch of anomalies anymore. Scientists say these occurrences are part of a rapidly changing ecosystem. In other words, it’s the new normal. And rather than try to prevent something that’s already here, ocean and fishery management has to evolve with it.

Steve Marx, a Pacific Ocean conservationist at Pew Charitable Trusts, put it this way: Scientists typically look at things like commercial fishing pressure and ocean conditions to predict population cycles. Those models aren’t working anymore.

“Everything we know about (forecasting) is getting thrown out the window,” he said. “So, yes. Crazy things.”

What happened after the blob arrived and started to spread had never been seen before. It brought new visitors to the Northwest: tropical copepods.

Peterson, who teaches oceanography at Oregon State University, said they’re beautiful but they’re causing problems for predators. The tropical plankton are not as fatty as the native plankton, and predators are passing on them. Meanwhile, the native, cold-water plankton started breeding late this year and their population has dropped below normal.

Scientists also are noticing that krill, another bottom-of-the-chain prey, have been largely absent this year.

Jaime Jahncke, a biologist at Point Blue Conservation Science, said during a research cruise off San Francisco a few weeks ago his team found few adult krill, mostly just juveniles. Data isn’t out yet for Alaskan krill, but scientists say it’s likely the same situation.

There’s speculation that the blob is sending them away, but no one knows enough to confirm it.

Meanwhile, Jahncke and his team are seeing more tropical species, such as sunfish.

He called it a perpetuation of the warm water conditions.

In a separate development, humpback whales reportedly have been spotted this week hanging out in the mouth of the Columbia River near Astoria, presumably for the anchovies. That’s odd because humpbacks, unlike gray whales, are not known for swimming near shore.

The blob might also be to blame for a major die-off of Cassin’s auklets this past winter.

From California to Canada – but mostly in Oregon – beachgoers have reported hundreds of the small seabirds had washed ashore. By January, that number reached tens of thousands. That’s 100 times more than their average mortality rate.

Julia Parrish, a professor of aquatic and fishery sciences at the University of Washington, tracked the die-off and said one theory is that the birds had a particularly good breeding season, which made it harder for juveniles competing for food.

But it also might be the blob. Parrish said it’s possible the auklets didn’t want to eat the tropical plankton.

“There’s reason to believe that basically what was happening was suddenly the grocery store was full of all sorts of different food, and maybe the food wasn’t so good,” she said.

Peterson, on the other hand, theorized that because the seabirds can’t dive deeper than 40 meters, perhaps they couldn’t reach their prey, which would seek cooler water below the blob at 80 meters.

Then you’ve got the massive sea star die-off. Thousands of sea stars are turning to goo from a virus. Not that warm water is the cause, but it’s certainly known for spreading the rate of infection.

Not everything can be attributed to the blob, however. Sometimes it’s people.

U.S. officials say the nation accounts for 87 percent of all sardine fishing in North America. Supposedly Mexico catches 13 percent and Canada catches none. But Canadians disagree with that assessment, insisting they net a significant share.

The fact the countries disagree points to part of the problem. No one group is accurately tracking the catches. Which helps explain the fact that there’s also no standard for how many sardines trawlers can catch.

Though these forage fish normally do well in warm water, cooler water conditions before the blob arrived had brought their population down.

Combine that with overfishing, and the Pacific sardine population collapsed. According to the National Marine Fisheries Service, the West Coast Pacific sardine population has decreased 90 percent since 2007. That’s the lowest it’s been in decades.

That has spelled disaster for species dependent on sardines. Sea lion pups are starving and brown pelicans are refusing to mate.

And what about the salmon? They feed on sardines, too.

Salmon are a whole topic unto themselves. Populations have been suffering die-offs almost all summer in Oregon, mostly because of warm water in the Columbia River and its tributaries. The biggest mystery has been the disappearance of at least 250,000 sockeye traveling up the river out of an expected return of 500,000.

Ben Enticknap, a senior scientist at the international research group Oceana, said much of this problem is manmade because dams have hampered migration and, in some cases, blocked access to historical spawning grounds.

All this presents a conundrum for scientists.

“What do you do?” Enticknap said. “Do you ignore it and do nothing and just wait to respond to endangered species listings and extinction events? Or do you become more proactive?”

Marx, the Pew Charitable Trusts conservationist, said scientists generally focus on species as separate problems. But if you focus on one, you need to look at how it affects its relationship with other species. For example, if a conservationist is studying a struggling salmon species, Marx said, it’s important to also look at the fish the salmon is eating and the bird that’s eating the salmon.

“The one takeaway message we would have is … the need to manage and think of things in a bigger, multi-species ecosystem approach,” he said.

The Pacific Fishery Management Council, he said, is doing just that. With representatives from Washington, Oregon, California and Idaho, the largely government-appointed council is responsible for regional fishery management.

In 2013, the council adopted its Fishery Ecosystem Plan to incorporate more ecosystem science and management policies. It doesn’t necessarily wait for “perfect” science to consider action.

One of the first steps the council took was to address the sardine issue. All fishing is halted for the rest of this season and the next. New fisheries can’t be developed, either, until there is more science on how to sustain it.

Enticknap, a conservation adviser on the ecosystem advisory panel, called it a progressive move.

“For the longest time, fisheries would just start up and then people would be reacting to a collapse to overfishing, and this is reversing that whole concept.”

Other organizations have launched related efforts.

Oceana is working to protect seafloor habitats from trawling. Enticknap said when large fishing nets are dragged across the ocean floor, coral and sponges are knocked over or caught by accident.

At OSU, researchers are asking volunteers to run climate models on their computers to understand the blob’s origin and whether it’s a symptom of climate change.

And the state Legislature approved protected marine areas in Oregon, such as Cascade Head, Cape Perpetua and Redfish Rocks. These areas are open to recreational use, but not commercial fishing.

One thing to keep in mind, though, is that not all species are struggling. Sometimes when one suffers, another prospers.

Marx said hake, or Pacific whiting, is relatively abundant at the moment.

The oceanographic climate shift, he said, “is good for some things. It’s bad for a lot of other things.”

  3. In Dec. World Leaders are to meet in Paris to discuss Global Warming, at issue is the amount of greenhouse gases we our emitting, and their plan of action.

    “A greenhouse gas is any gaseous compound in the atmosphere that is capable of absorbing infrared radiation, thereby trapping and holding heat in the atmosphere. By increasing the heat in the atmosphere, greenhouse gases are responsible for the greenhouse effect, which ultimately leads to global warming.” Live Science

    Globally we our emitting 40 – 50 Billion Toxic Tons a Year.

    The United States emitted 6.8 Billion Toxic Tons in 2014

    In the 1850s – 1870s parts per million of Carbon in our atmosphere was between 260 – 280.

    In the 1980s, there was 350 ppm of Carbon.

    2015 – 404 ppm in Our Atmosphere.

    We have just passed the 1C. Global Temp. rise.

    The Pacific Ocean is 3 – 6 degrees warmer than Normal.

    The Jet Stream is acting like a balloon that is loosing air.

    The Arctic Ice and Snow may be gone at the end of this Summer. A Huge Natural Cooler for the Northern Hemisphere.

    The meeting in Paris, should be about Closing the Fossil Fuel Faucet.

    “Professor Chris Field is bullshitting the planet. On whether 1.5C is still feasible” Kevin Hester

    “The message is already clear, that if the world does want to strive to limit warming to 1.5C or less, we don’t have very much of the carbon budget left.” Professeor Chris Field

    “There is no carbon budget any more and 5C is baked in according to both Shell petroleum and the International Energy Authority. ” Kevin Hester

    “Chris Field is the founding director of the Carnegie Institution’s department of global ecology and professor for interdisciplinary environmental studies at Stanford University. He is the co-chair of the Intergovernmental Panel on Climate Change’s (IPCC) working group two (WGII) and US nominee for the chair of the IPCC.”
    With people like this driving the IPCC you can see why we are all done for.” Kevin Hester.

    There is No Carbon Budget

    California emitted 459 Toxic Tons of Carbon Dioxide in 2014.

    Gov Browns call to reduce this to 1990 levels so we can continue to emit over 400 million Toxic Tons a year, will not help us stop or slow down Global Warming and Sea Levels Rising.

    “Updates to the 2020 Limit.
    Calculation of the original 1990 limit approved in 2007 was revised using the scientifically updated IPCC 2007 fourth assessment report (AR4) global warming potentials, to 431 MMTCO2e. Thus the 2020 GHG emissions limit established in response to AB 32 is now slightly higher than the 427 MMTCO2e in the initial Scoping Plan.” Ca. Gov. Data

    What will the Temp. be at 415 ppm ?

    “Ice sheets contain enormous quantities of frozen water. If the Greenland Ice Sheet melted, scientists estimate that sea level would rise about 6 meters (20 feet). If the Antarctic Ice Sheet melted, sea level would rise by about 60 meters (200 feet).” National Snow and Ice Data Center.

    When will Sea Level Rise to 220 – 300 Feet ? 2020 ? 2025 ? ?

    What will the ppm of Carbon be when this happens ?

    As of Now, they are talking about capping GHGs at 450 ppm.

    What will the Temp. be at 450 ppm ?

    We must transition to 100% Renewable Energy

    Implement a California Residential and Commercial Feed in Tariff.

    California Residential Feed in Tariff would allow homeowners to sell their Renewable Energy to the utility, protecting our communities from, Global Warming, Poison Water, Grid Failures, Natural Disasters, Toxic Natural Gas and Oil Fracking.

    A California Commercial FiT in Los Angeles, Palo Alto, an Sacramento Ca. are operating NOW, paying the Business Person 17 cents cents per kilowatt hour.

    Sign and Share this petition for a California Residential Feed in Tariff.

  4. were doomed half the people in the world don’t believe in global warming and the governments don’t care most are greedy and only care about money and power
