Shows a quite cold pool in the Gulf of Mexico - but with a warm centre - is
this to do with undersea contours or something else I wonder. It shows up
very well on IR images from the GOES E satellite.

This is the so-called "Loop Current". It's a common feature in the Gulf of
Mexico. There's a huge number of references available if you Google "Gulf of
Mexico Loop Current".
