Study: Heatwaves Can Force Ocean Life to Flee Great Distances

According to a new study, heatwaves will cause fish and other ocean species to migrate thousands of kilometers in search of cooler waters. The research was published by scientists at the US National Oceanic and Atmospheric Administration (NOAA). Their study is based on a novel method of calculating heatwaves known as “thermal displacement.” It refers to the distance that fish, whales, and other mobile animals must migrate to find cooler ocean surface temperatures, and the pace at which weather condition varies around the ocean determines the calculation. Earlier studies, according to NOAA, focused on how hot weather can gradually raise ocean surface temperatures. Heatwaves alter the ocean climate, causing vast numbers of seabirds to perish and corals and other sea life to suffer. The research discovered that cooler water can be close to warmer waters in certain areas, such as where various parts of the ocean intersect. Any sea creature will have to travel more than 2,000 kilometers to reach cooler water in tropical regions, where temperature differences are typically negligible. The analysis might give us an idea of how the environment might evolve in the future, according to the researchers. This may, for example, help fishermen estimate how long they will have to go to catch the fish they want.
