New Temperature Anomaly Spreads From Alaska to California and Looks Even Worse Than ‘The Blob’ From 5 Years Ago


About five years ago “the Blob” of warm ocean water disrupted the West Coast marine ecosystem and depressed salmon returns.

Now, a new temperature anomaly has quickly grown in much the same way and to almost the same size from Alaska to California. The new Blob looks even worse than 5 years ago in the below map by NOAA:

About five years ago “the Blob” of warm ocean water disrupted the West Coast marine ecosystem and depressed salmon returns.

Now, a new expanse of unusually warm water has quickly grown in much the same way, in the same area, to almost the same size.

The warm expanse building off the West Coast stretches roughly from Alaska south to California.

It ranks as the second largest marine heatwave in terms of area in the northern Pacific Ocean in the last 40 years, after “the Blob.”

It’s on a trajectory to be as strong as the prior event,” said Andrew Leising, a research scientist at NOAA Fisheries’ Southwest Fisheries Science Center in La Jolla, California. He developed a system for tracking and measuring heatwaves in the Pacific Ocean using satellite data. “Already, on its own, it is one of the most significant events that we’ve seen.

Cold water welling up from ocean depths along the coast has so far held the warm expanse offshore, he said. However, the upwelling, driven by coastal winds, usually wanes in the fall. The heatwave could then move onshore and affect coastal temperatures, he said. This already appears to have happened along the coast of Washington.

The Northeast Pacific Marine Heatwave of 2019

NOAA Fisheries is focusing additional monitoring on the new heatwave, designated the Northeast Pacific Marine Heatwave of 2019. NOAA Fisheries’ Southwest and Northwest Fisheries Science Centers will provide fisheries managers and others with information on how the unusually warm conditions could affect the marine ecosystem and fish stocks.

We learned with ‘the Blob’ and similar events worldwide that what used to be unexpected is becoming more common,” said Cisco Werner, NOAA Fisheries Director of Scientific Programs and Chief Science Advisor. “We will continue to inform the public about how the heatwave is evolving, and what we might anticipate based on experience.

The new heatwave resembles the early stages of “the Blob.” This previous marine heat wave peaked through 2014 and 2015 with temperatures close to seven degrees Fahrenheit above average.

Like “the Blob,” the new heatwave emerged over the past few months. A ridge of high pressure dampened the winds that otherwise mix and cool the ocean’s surface. The heatwave remains relatively new and is primarily affecting the upper layers of the ocean, it could break up rapidly.

It looks bad, but it could also go away pretty quickly if the unusually persistent weather patterns that caused it change,” said Nate Mantua, a research scientist at the Southwest Fisheries Science Center.

Current forecasts show the heat wave moderating but continuing for months.

Pacific Heatwave Impacts

A key question is whether the new heatwave will last long enough to affect the marine ecosystem. Biologists say that its large size means it probably already has. For example, warmer conditions during “the Blob” left lesser-quality food available to young salmon entering the ocean. It also shifted predator distributions in ways that contributed to low returns of salmon.

Other impacts linked to the earlier heatwave include:

  • The largest harmful algal bloom recorded on the West Coast, which shut down crabbing and clamming for months.
  • Thousands of young California sea lions stranding on beaches.
  • Multiple declared fishery disasters.

NOAA Fisheries scientists recently convened a special meeting to discuss the emerging heatwave and how to anticipate and track its effects. They are now reviewing impacts documented during the “the Blob” to compare them against the effects of the emerging heatwave.

Given the magnitude of what we saw last time, we want to know if this evolves on a similar path,” said Chris Harvey, a research scientist at the Northwest Fisheries Science Center.

Scientists Monitor the New Blob

NOAA Fisheries’ two West Coast laboratories collaborate on the California Current Integrated Ecosystem Assessment. This is a joint effort to track and interpret environmental change off the West Coast. That provides a framework to monitor shifting conditions, Harvey said.

One challenge will be applying lessons learned from the last heat wave to anticipate and mitigate potential impacts of the new one. For example, the warm water of “the Blob” led humpback and other whales to feed closer to shore. Record numbers became entangled in lines from crab traps and other fishing gear.

In response, fishermen, managers, and others have formed working groups in California, Oregon, and Washington. They hope to find ways of reducing the risk of entanglements.

Real-time research on environmental changes will give managers the details they need to respond, said Kristen Koch, Director of the Southwest Fisheries Science Center. “This is a time when we all need to know how our marine ecosystem is changing, and what that means for those of us who live along the West Coast.” 

The new northeast Pacific heatwave reflects current weather patterns. This includes a band of high pressure stretching north to the Bering Sea and Alaska, which have been unusually warm in recent years.

There are definitely concerning implications for the ecosystem. It’s all a matter of how long the new temperature anomaly in the Pacific ocean lasts and how deep it goes. But let me tell you this. The new Blob heatwave has already scarred ecosystems from Alaska to California for life. [NOAA]

  1. All of this discussion and submarine volcanism is conspicously ghosted. The heat is coming from below. Such activity is ghosted because it is conveniently concealed out of sight (underwater), and incovenient to the climate change narrative. The interior of the planet is becoming increasingly destabilized. The heat is no longer in containment. Polar regions will melt from this as well. The air is not melting the ice or heating the ocean. The earth is heating the ocean, which affects polar ice and air masses. Deep EQ events, and EQ in general are way up when charted over a three decade span. Major changes inside the Earth underway.

  2. Heat in the water take a lot longer to dissipate then heat in the air and yet they keep pumping cold water into the power stations and hot water back into the oceans and not only this they are submerging data centers into the oceans as a way of reducing the cost of cooling. Global warming is insignificant compared to these fools who are heating up the oceans and will kill all sea life.

    Revelation 16:3
    The second angel poured out his bowl on the sea, and it turned into blood like that of a dead person, and every living thing in the sea died.

    (It is not the angel doing this but mankind and their technology)

  3. Planet X Over Dorian
    It’s Wormwood that is causing all this wild weater not climate change. My opinion.
    Explanation here, starts when I mention Richard Coombs.

  4. Fukushima radiation is here on our shores make no mistake. Ocean life is in peril and with reports of sickness and starvation of all sea life Tepco is going to dump all of their stored radiated water into the sea! NO radiation testing. So enjoy your seafood folks. We are on our own!

    • No idea what is causing the increase?? FUKUSHIMA heating is CUMULATIVE. But nary a footnote in this article. Waste of time.
      At this late stage? done waste time listening to hours of youtubes that wont touch the core. Or articles that wont address the source. Too late and too little time left to waste.
