May 12, 2022 — In 2019, about 4,600 miles from Arizona, a marine heat wave cranked up the temperature in the waters around Hawaii. For several sweltering summer months, a low pressure system sat over the Pacific Ocean between Hawaii and California and led to decreased cooling winds and sea surface temperatures 4.5 degrees Fahrenheit higher than normal.
Scientists called it “The Blob 2.0.” The original “Blob” developed in 2013 as a strange pool of warm water off the coast of Alaska, then quickly expanded all the way to Mexico in a meteorological phenomenon that lingered until early 2016 and “was so persistent and unusual that it initially defied explanation,” according to NASA.
Marine life suffered in both “Blob” events. In the mid-2010s heat wave, higher ocean temperatures fueled the growth of less-nutritious types of algae. Populations of salmon and other important fish species plummeted, straining the Pacific fishing industry. Fin whales and sea otters started washing up dead while baby seals starved on shore for all to see. And nobody quite knew what was going on.
