@@@ Long-established species of commercial fish, such as cod, herring and northern shrimp, are departing for colder waters. Black sea bass, blue crabs and newly arrived species of squid 鈥?all highly unusual for the gulf 鈥?are turning up in fishermen鈥檚 nets. The Gulf of Maine鈥檚 warming reflects broader trends around the North Atlantic. But the 99 percent statistic 鈥?accepted by scientists at NOAA, the National Oceanic and Atmospheric Administration 鈥?underscores particular fears about the gulf鈥檚 unique ecosystem and the lucrative fishing industries it supports for three U.S. states, including Maine, and two Canadian provinces. 鈥淭hese changes are very real, and we鈥檙e seeing them happen quickly,鈥?said Malin Pinsky, a biology professor at New Jersey鈥檚 Rutgers University who studies ocean temperature change and was not involved in the research that resulted in the 99 percent number. It is a <a href=http://www.museosangennaro.com/Public/anel.php> Christian Louboutin Shoes Sale</a> rallying point for environmental activists, who see the response to the temperature rise and its impact on fisheries as a touchstone for the global debate about climate change. 鈥淭he warming is already here,鈥?said Jeff Young, a spokesman for Pew Charitable Trust鈥檚 oceans project, which has campaigned in favor of restrictions on fishing for herring, another species leaving for colder water. 鈥淎nd we have to deal with it.鈥? The rising waters in the gulf 鈥?a big dent in the East Coast stretching from Massachusetts to Nova Scotia and New Brunswick 鈥?have interfered with the work of Diane Cowan, founder of the Lobster Conservancy, who has conducted lobster censuses in New England for 22 years. The shore of a cove off Maine鈥檚 Friendship Long Island, in Knox County, has long been the best site on the East Coast to find baby lobsters, she said. Around 2007, she couldn鈥檛 lift a rock without finding one, and usually several. But the rising sea has prevented her from getting there much since <a href=http://capstone.edu.sg/images/gucciusaonlineoutlet.php> cheap gucci</a> 2010, she said, because the shore is almost always underwater. On a recent August morning, she made it to the site and found 19 young lobsters 鈥?a big drop from the huge colonies seen seven years ago, Cowan said. 鈥淭hings have changed dramatically,鈥?she said. The rising sea is connected to the warming waters because higher temperatures make the water less dense, said Bob Steneck, a professor at the University of Maine鈥檚 School of Marine Sciences. Until 2004, gulf temperatures had been increasing by about 0.05 degrees per year since 1982, in line with worldwide trends, said Andy Pershing, chief scientific officer at the Gulf of Maine Research Institute in Portland and the man behind the 99 percent figure. But then the pace accelerated to about a half-degree per year 鈥?nearly 10 times faster. Scientists are not certain why. The rest of the world鈥檚 large bodies of saltwater are also warming, albeit not as fast, as increased carbon dioxide in the air has contributed to rising temperatures, Pershing said. 鈥淎tmospheric events鈥?could be pushing additional heat into the gulf, causing a 鈥減erfect storm鈥?of conditions that combine to dramatically raise temperatures there, said Nick Record, a research scientist at the Bigelow Laboratory for Ocean Sciences, a Maine center for oceanography in Boothbay. Pershing and many peers agree. Another possible cause, Pershing said, is that shifts in the Gulf Stream, the Atlantic current that originates in the Gulf of Mexico and keeps Europe鈥檚 weather mild, warmed the ocean off the Northeast. The Gulf of Maine鈥檚 temperature is expected to rise more than 4 degrees by the end of the century, Pinsky said. The 99 percent statistic isn鈥檛 arbitrary. Pershing and others compared ocean trends and presented the figure to the NOAA in April. Pershing鈥檚 work illustrates that the Gulf of Maine is indeed among the fastest-warming bodies of water, said Roger Griffis, climate change coordinator for the NOAA Fisheries Service. The gulf, he said, is 鈥渙ne of the poster children, unfortunately, for major changes.鈥? Its historically cold temperatures and strong tidal currents, which mix the waters and increase nutrients, make it one of the most productive marine ecosystems and a key summer territory for rare whales. But half of 36 fish stocks studied in the Northwest Atlantic Ocean, including many commercial species, have been shifting northward over the past 40 years, a 2009 NOAA report said. Ironically, the warmer water has created ideal conditions for lobsters and contributed to an overabundance in recent years, causing prices to tumble in 2012 to their lowest point in nearly <a href=http://www.alportico.net/gosoc.php> true religion outlet</a> two decades in Maine. But continued warming could force lobsters to move north or die off, Steneck said. Puffin chicks have starved and died because of a lack of the herring and hake they need to grow and fledge. Seemingly overnight, longfin squid 鈥?normally found in warmer, more southerly waters 鈥?appeared, Record said. Scallops, also an important economic element in the gulf, are vulnerable to ocean acidification, which scientists say is another effect of increased carbon dioxide in the atmosphere. The changes threaten a three-state industry valued at more than $1 billion in 2012. Governments are reacting by creating new commercial fisheries, and Maine regulators are working on creating a licensing process for black sea bass, a species associated more with the mid-Atlantic.
