For almost 20 years, Australian oceanographers have had a role in ocean yacht racing on the east coast of Australia, detailing their understanding of ocean conditions along the course for interested skippers and crew. Dr George Cresswell has headed this activity and his thoughts on it can be found here in Oceanography and the Sydney to Hobart Yacht Race. Also read the article by Craig Macaulay, East Australian Current for more information on the East Australian Current. The images on these web pages come from measurements by infrared sensors aboard American NOAA satellites of the heat emitted by the earth's surface. The sensor data are broadcast via radio which are received at Coffs Harbour and converted to sea surface temperature and corrected for geometrical distortion. The images use colour to describe sea surface temperature. A rainbow scale of colours (colour table) is used: red is warm and blue is cold; clouds are white. The images have a latitude-longitude grid and the 200m depth contour (shelf edge) is marked. This site includes satellite sea surface temperature images from 1997 to present.

With assistance from CSIRO's Remote Sensing Unit, based in Hobart, regular satellites images are being uploaded to this site until the conclusion of the race. Ocean conditions are also of broader interest to industry and authorities concerned with maritime safety, environmental protection, shipping and navigation, commercial fishing and sportsfishing, and defence. Ocean mapping of Australia's Exclusive Economic Zone to meet business, industry and defence needs began in 1997. |
