The scientists found that phytoplankton are about 65% less productive in the Gulf of Maine, part of the Atlantic Ocean bounded by New England and Canada, than they were two decades ago.
. The loss of the tiny organisms has the ability to disrupt valuable fishing industries for species such as lobsters and scallops, and it could further jeopardize imperiled animals such as North Atlantic right whales and Atlantic puffins, scientists said.
The scientists did the study using data gathered since 1998 by tracking chemical changes in the Gulf of Maine. The samples used to perform the work were gathered via commercial ferries and research vessels that run the same routes over and over. Decline of fish stocks in the Gulf of Maine would be especially disruptive to American fishermen because it's a key ground for the U.S. lobster industry. Other important species such as haddock, flounder and pollock are also harvested there.
found that climate change “is predicted to trigger major shifts in the geographic distribution of marine plankton species.”pattern, when surface water in the equatorial Pacific becomes warmer, can reduce phytoplankton production, the National Oceanic and Atmospheric Administration has said. The impacts include lack of anchovies off South America, fewer squid off California and less salmon in the Pacific, NOAA said.
