World has ended for Nelson Mandela as this anti-apartheid hero died at an age on 95 on Thursday...
Recent data from the National Oceanographic and Atmospheric Administration (NOAA) has shed light on the fact that the surface temperature of Northeast Shelf Large Marine Ecosystem has come across the highest rise in about 150 years.
The area starts from the Gulf of Maine to Cape Hatteras, North Carolina. It came across as a rise in sea surface temperature in 2012. This was approximately 14 degrees Celsius (57.2°F) greater than average sea surface temperature of <12.4 C (54.3 F) as witnessed in past 30 years.
The data developed by Ecosystem Advisory has been issued by NOAA's Northeast Fisheries Science Center (NEFSC).
The data has been recorded since 1854 with the aid of ship-board measurements. But, last year, there was a great rise witnessed both in long-term measurements and short-term remote sensing.
The pattern that was seen last year has also been recorded. It involves rise in temperatures in Northeast Shelf from spring of 2012 to September. The temperatures again plummeted in October. By the end of mid-November, the temperatures dipped below-average in the Middle Atlantic Bight. The reason behind the same could be Superstorm Sandy.
Such changes in temperature influence the health of plankton and marine life. Many types of fish have been moving northward from the past four decades.
