    A record-breaking toxic algae bloom that began in May along the West Coast is denser, more widespread and deeper than scientists originally feared, and it has expanded into the Aleutian Islands of Alaska.
    Algae blooms are not uncommon in the Pacific Ocean but the size and duration of this one, stretching from Southern California to Alaska, is historic, according to NOAA, and it continues to impact marine life and local economies to the tune of millions of dollars.
    The toxic algae bloom is up to 40 miles wide and 650 feet deep in places, according to surveyors aboard a NOAA research vessel.
    Vera Trainer of NOAA’s Northwest Science Center told USA Today recently that “It’s unprecedented.”
    Trainer said it’s the worst she’s seen it in the 20 years of studying toxic algae blooms, saying they are usually limited to one area of the ocean or another and disappear after a few weeks. This one has grown for months and it isn’t going away.
    “It’s been incredibly thick, almost all the same organism,” UC Santa Cruz ocean sciences professor Raphael Kudela told AP. “Looks like a layer of hay.
    “It’s really working its way into the food web and we’re definitely seeing the impacts of that.”

    In the past month, 21 humback and fin whales have been found dead in southeast Alaska, and in July the Aleutian Pribilof Islands Association received reports of dead and dying whales, gulls and forage fish in the Aleutian Islands. Samples are being tested for algal toxins.
    Extremely high levels of the algal toxin called domoic acid has led to the closures of recreational razor clam digging in Oregon and Washington, along with large portions of the Dungeness crab fishery in Washington, and the sardine and anchovy fisheries in California.
    NOAA reported that coastal communities in Washington lost an estimated $9 million in revenue in May alone as a result to the razor clam closure.
    “Algal blooms in the ocean are made up of microscopic marine plants known as phytoplankton,” NOAA noted. “Not all phytoplankton are dangerous, but certain species produce dangerous neurotoxins. Shellfish and some fish eat the toxic algae as part of their normal diet, which can then expose their predators—including marine mammals and humans—to the neurotoxins in amounts that can cause illness and, in extreme cases, death.”
    The algae bloom coincides with sea surface temperatures that are well above average across the North Pacific and West Coast.
    “The primary reason they are above normal is a strongly positive Pacific Decadal Oscillation (PDO), which is a horseshoe pattern of warmer-than-normal waters along the coast of western North America,” AccuWeather meteorologist Anthony Sagliani said.
    “Though SSTs will drop some through the fall and winter, as it typically the case, the positive PDO and El Niño will remain, or even intensify, and as such, so too will the above-normal water temperatures. El Niño does not play a direct role, but generally speaking, El Niños are more likely to occur during a positive PDO.”
    If this El Niño is the Godzilla of El Niños, then this toxic algae bloom is the king of all toxic algae blooms.
