Figure 1.
The average ship-drift dervied surface velocities show the well-know
omega-shaped flow pattern of the Loop current. The Loop Current
(1) feeds the Florida Current that transports significant amounts of
heat poleward;
(2) transports surface waters of tropical origin into the Gulf of Mexico; and
(3) is fed by the Caribbean current and the Yucatan Current.

Figure 6.
The trajectory of near-surface drifters that show the same circulation
pattern as discussed in Figure 1. Though these four drifters were launched
in very different locations in the subtropical Atlantic and Caribbean Sea
they all ended up in the Loop current with very similar trajectories
and near 25°N, the drifters all flow through basically the same small
region off of the Florida Keys.

Figure 7.
An image of the sea surface temperature in the Gulf of Mexico.
Red colors are water with surface temperatures near 80 °F (27 °C)
and are associated with the Loop Current.
The image also shows small cyclonic eddies that are common in this region.
This is an analysis by ROFFs for monitoring the 2010 oil spill and

(ROFFS).

Figure 11.
A SST map illustrating the large extent of the Loop
Current into the Gulf of Mexico. This SST map is from
February 19-20, 1996. Also evident is the Florida Current, offshore
of the east coast of Florida, cool coastal waters around the
Gulf Coast states and northern Florida, and a warmer filament
of surface water being wrapped around the Loop Current indicating
that a Loop Current Ring will probably detach from the current.
