Analysis of Deepwater Horizon Oil Spill Area, Roffer’s Ocean Fishing Forecasting System, July 12, 2010:
The water south of the Deepwater Horizon site now appears to be moving more southward toward 88°00-90°30’W between 28°30’N and 27°30’N, but then it continues to be pulled southeastward toward 87°00-88°00’W & 27°00’N...
On your way southwestward from Tampa/St. Petersburg, FL, we would suggest that a good area to sample for surface and subsurface oil would be along the stong [sic] convergence zone from 84°00’W & 26°35’N to 84°30’W & 27°15’N and also from 84°55’W & 27°30’N to 85°15’W & 27°45’N where the water masses appear to have remained relatively stable for the past four days.
Continuing westward, we continue to monitor the currents associated with a cyclonic eddy centered near 85°30’W & 27°25’N and an anti-cyclonic eddy centered west of Naples near 84°40’W & 26°15’N. This is a classic “hammerhead” circulation that is pulling a relatively small portion of the WOM eastward to the Florida continental shelf edge and perhaps northward towards the northern eddy. This circulation is likely to persist for a few days at least. ...
We were able to confirm the position of the surface oil particularly east and south of the Deepwater Horizon well site with this afternoon’s MODIS visible RGB imagery.
ROFFS explains the newly added areas of red and purple on the map:
Today we have provided a second graphic, which shows areas where the convergence zones have remained stable for three days in opaque red and areas where the convergence zones have remained stable for four days in opaque purple.
These areas highlighted in opaque red and purple are likely to contain the strongest convergence zones which are likely to contain a combination of oil (in areas where they overlap the water masses we have labeled with “WOM), sargassum, fish, and bait.
The WOM label is water/oil/dispersant mix:
