Ocean waters around the New England continental shelf turned out to be warmer than normal due to changes in the usual course The Gulf Stream, which originated about a year ago. Start learning this phenomenon was laid by local fishermen who reported to a science institute about their concerns about the abnormally warm water on the surface of the ocean and increased water flows. So with In the fall of 2011, the collection and recording of data on the Gulf Stream channel began. At the remote points of the continental shelf, two temperature sensor. As it turned out, the water at these points has become warmer by 6.2 ° C and 6.7 ° C. When the water in this place of the ocean is so warm (+ 18 ° C) in autumn, it is more than abnormal, they say researchers.

The temperature indicator for December at one of the points became an absolute record for this area over the past 6 years. Analysis salinity levels from December to January and comparison with archival data showed that increasing salinity of water corresponds to warming periods in 2011 and intersects with the salinity of the waters brought by the Gulf Stream. That is, the water has become more warm and salty in the study area, because it brought Gulf Stream along a changed channel, adjacent closer to the continental shelf.

Golfstim location change was determined using special drifters launched into the ocean. They slowed and accelerated speed depending on the heat of the water. Warmer water corresponded to the boundaries of the current, the center of which is now in coordinates 39.9 ° N; 68 ° W, which is 200 km north of normal. Such large-scale shift of such a significant mass of warm water and an increase its temperature at least 2 ° C will soon affect all the inhabitants of the sea. Silver hake populations have already migrated in the spring of 2012, much earlier migration of bluefin and striped perch, whose jambs rushed away from the coast cape code. To further predict and identify the causes of the shift in The Gulf Stream needs a more detailed study of change, occurred with the Gulf Stream.
