Scientists uncover diversion of Gulf Stream path in late 2011

October 14, 2012MAINEAt a meeting with New England commercial fishermen last December, physical oceanographers Glen Gawarkiewicz and Al Plueddemann from the Woods Hole Oceanographic Institution (WHOI) were alerted by three fishermen about unusually high surface water temperatures and strong currents on the outer continental shelf south of New England. “I promised them I would look into why that was happening,” Gawarkiewicz says. The result of his investigation was a discovery that the Gulf Stream diverged well to the north of its normal path beginning in late October 2011, causing the warmer-than-usual ocean temperatures along the New England continental shelf. The researchers’ findings, “Direct interaction between the Gulf Stream and the shelfbreak south of New England,” were published in the August 2012 issue of the journal Scientific Reports. To begin to unravel the mystery, Gawarkiewicz and his colleagues assembled data from a variety of sources and recreated a record of the Gulf Stream path during the fall of 2011. “These are very dramatic events for the outer continental shelf, at least 2 degrees C warmer than we’ve seen since 2001,” says Gawarkiewicz. “Near-bottom temperatures of 18 degrees C on the outer shelf are extremely high for late autumn.” The maximum recorded temperature in December 2011 was the warmest bottom temperature recorded in 6 years of records at the OC01 site. Gawarkiewicz and his colleagues collected additional data on water temperature and salinity from December 4, 2011 through January 4, 2012, from instruments on temporary test moorings placed 12 km south of the shelfbreak by the Ocean Observatories Initiative (OOI). The researchers compared those salinity measurements to historical data, and discovered that high salinity levels – consistent with the salinity of waters carried by the Gulf Stream – coincided with the warming periods. –Terra Daily

    We know Greenland was given quite a beating via the elites using HARRP there. Cause a huge melt-off of the ice-snow covering much of that territory.Are these issues related?

    Did mention this before Alvin? Nice to have conformation of my observations from an authoritative source but not nice considering the implications for the UK, esp northern parts, come winter.

    Has the Gulf Stream moved? http://www.nhc.noaa.gov/refresh/graphics_at5+shtml/143946.shtml?basin#contents
    Have been watching Hurricane Nadene sitting still (unusual) below the Azores for over a week and now it is moving NNW. Tropical Depression FIFTEEN has formed and is following the the same course rather than moving West like other cyclones towards the warm waters of the Gulf. Something amiss possibly?

    PS.
    Possibly a portent of more tropical storms with gales, floods or heavy winter snow for the UK soon?

      Hi Mike, we live in Bristol, UK. We are experiencing a colder than usual winter/ spring here and it looks like were running out of gas to heat our homes ( for those who can afford to). Do you think this is because of global warming and that the gulf stream is changing course away from the British Isle’s ?
      That’s what seems to be happening, is there any further issues in relation to weather we shoud be aware of for the future ?

      Regards Seamus and Maria Bristol, UK.

    Something to deo with the Deep Water Horizon blow up ?

  4. tonic says:

    Is this the beginning of the end of the Gulf stream? With so much freshwater pouring in from the Arctic ice melts, salt, salinity, is decreasing in the ocean in that area, and the Gulf Streams normal route is interrupted.?

    It looks BAD!…and BP should have paid trillions of $!

    Is there any evidence, data charts, research or studies done that link this article to the Gulf of Mexico/Macondo Well disaster from April 2010?
    Also, whenever I see the “jet stream” on a weather forecast in the U.S., I just can’t see a reason to believe it’s still controlling the weather.
    They (NOAA, OII) know the average person would have no way of knowing that what they’re showing us is real or true, especially considering they’re always wrong or off in their ‘forecast’.
    Anything can be manipulated and edited for consumption.
    Any insight or links appreciated.
