Warming Waters Worldwide Cause Marine Species Migrations


Edwin Hammond Meredith is a Florida Keys resident who holds a position as chef and enjoys various marine activities that the region offers, from fishing to stand-up paddle boarding. Edwin Hammond Meredith has a strong interest in marine biology and the systems that support life in the world’s oceans.

One area of concern among marine biologists in recent years involves entire species migrating toward regions with cooler waters as global warming takes effect. One casualty has been lobsters in Long Island sound, who have been driven out of their local habitat by a series of warm summers to cooler locales such as the Gulf of Maine. Unfortunately, as reported by National Geographic, this refuge may also be temporary, as water temperatures in that region are rapidly accelerating.

Along the Pacific coast of North America, this warming trend has affected species such as arrowtooth flounder and Pacific halibut, which have shifted from the Bering Sea to the more northerly Arctic Ocean. Other fish are moving north from tropical latitudes, such as the invasive lionfish that is now common along the Atlantic Coast. A key question posed by these migrations is how to maintain the fisheries that support jobs and food production in the face of persistent oceanic warming.
