New Loop Current Eddy Forms in Gulf of Mexico

As we were monitoring the conditions in the Gulf 
of Mexico this morning we observed several clear 
indications that a relatively large, clockwise 
rotating Loop Current eddy appears to have 
formed. The water of this anti-cyclonic eddy is 
rotating separately from the Loop Current. There 
is cooler water (less red/more orange on image) 
from the west Florida shelf being pulled around 
the eddy. We started to see this formation on 
November 07, 2011 and the development has 
continued for a week. Movie loops show the 
motion. Below is a false color enhancement of a 
two day (November 13 - 14, 2011) ROFFS sea 
surface temperature  (SST) composite derived from 
a variety of infrared sensors on the NOAA, NASA 
and European Space Agency satellites. Also below 
are two independent graphics (NOAA_AOML and Univ. 
Colorado) derived from altimetry data from a 
longer period that shows this eddy and 
circulation field.  The ocean color imagery (not 
provided here) also additional verification. The 
Loop Current SST is   27.6-27.7C (81.7-81.9F) 
and eddy is 26.8-27.1C (80.3-80.8F) .

We will continue to monitor this to see if 
remains separated from the Loop Current. 
Presently the eddy is pulling a filament of the 
Loop Current water around the western side of the 
eddy, but most of the Loop Current water appears 
to be flowing eastward toward the Straits of 
Florida. North of the Loop Current eddy is 
another counter-clockwise flowing eddy. This 
situation is very similar to the circulation we 
observed during the BP Deepwater Horizon oil 
spill episode. We also continue to receive 
reports of good tuna fishing action along the 
northern boundaries of the blue Loop Current 
water from south of the Mississippi delta and 
eastward over the Desoto Canyon area.
