Surface current map of the Turquoise Coast domain derived from two SeaSonde (direction finding) radar stations at Seabird and Cervantes in Western Australia. Seabird and Cervantes SeaSonde stations utilise a GPS time synchronised transmit frequency at 5.2115 MHz with 50 kHz of bandwidth. This particular map was created from 79-minute weighted-average cross spectra from which radial data for each station is sampled at 60-minute intervals. Radial current components from the two stations are combined at the central laboratory to form the map of surface current vectors shown here. This 60 minute sample was from 9 February 2011 at 0400 GMT and has not been processed through ACORN quality control.
