Perpetual Ocean

This is a still photo from a film running on a screen in the lobby of the British Library in London. The sign next to it reads:

Perpetual Ocean
This striking animation by NASA visualises the flow of ocean surface currents from June 2005 to December 2007. Today's scientists have access to an enormous amount of data collected by satellites and monitoring stations and the supercomputing power to analyse and create useful renderings. Displaying this data visually allows scientists and the public to better understand how ocean circulation evolves over time and how this impacts on weather around the globe. One noticeable feature is the Loop Current in the Gulf of Mexico (shown at the start of the film), which plays a major part in the intensification of hurricanes in the Atlantic.

Taken during a break this afternoon between a meeting of the Friends Housing Bursary Trust, and meeting my friends and ex-colleagues, Soosan and Katherine, for dinner.
