The Blob is an anomalous body having sea surface temperature much above normal, seen here in a graphic of April 2014 by the NOAA. The Blob is a large mass of relatively warm water in the Pacific Ocean off the coast of North America that was first detected in late 2013 and continued to spread throughout 2014 and 2015.

One of these scientists, researcher Chelle Gentemann, grew up on the Pacific Coast, where she and her family spent summers fishing for salmon. Now an oceanographer, Gentemann tracks ocean temperatures, and the blob had caught her and her colleagues’ attention. In September 2014, NOAA scientists noted that a buoy off the coast of Newport, Oregon, re...
To figure out where this inexplicable warmth was coming from, Gentemann and her colleagues tracked ocean temperatures using an ensemble data set: the Multi-scale Ultra-high Resolution Sea Surface Temperature (MUR SST) Analysis. This ensemble product combines readings from several satellite sensors, and is available from NASA's Physical Oceanography...
Scientists do not yet know what caused the unprecedented atmospheric ridge, or why it persisted so long. Some research hints that overall ocean warming stimulated this response. Other research indicates the opposite, that the ridge caused the blob to form, and a persistent feedback compounded the multi-year endurance of both blob and ridge. Yet oth...
28 de jun. de 2022 · The suffocating, hot blob of water that began in 2013 decimated marine life, killing more than 100 million Pacific cod, thousands of seabirds, and other animals not even accounted for.
31 de ene. de 2019 · In late 2013, a huge patch of unusually warm ocean water, roughly one-third the size of the contiguous United States, formed in the Gulf of Alaska and began to spread. A few months later, Nick Bond, a climate scientist at the University of Washington in Seattle, dubbed it The Blob.
5 de sept. de 2019 · 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.
17 de abr. de 2023 · The Blob is caused by a combination of warmer air temperatures (that warms the ocean’s surface), changes in the patterns of wind speed, direction and duration (wind helps mix the ocean and by bringing cool water from depth) and the persistent mass of warmer water along the equator known as ENSO.
8 de feb. de 2017 · This map shows anomalously high sea-surface temperatures in the Pacific Ocean in May 2015 as compared to the 2002–2012 average. The recent warm-water phenomenon is known as “the Blob.”
