공공데이터포털
The Bathurst Channel bathymetric layer1: 25,000 depicts depth contours for the entire channel from the inside of the Breaksea Islands to Nixson Point [148d 00m, -42d 30m] to [148d 00m, -42d 30m]. The contour intervals are 5m, 10m, 20m, 30m, 40m, 50m. The data was collected through intensive field sampling from by marine researchers at the Tasmanian Aquaculture and Fisheries Institute. The use of underwater camera equipment, echo sounder data and a Differential GPS unit allowed for the extensive area to be surveyed. The dataset is intended to be used to fulfil coastal management objectives according to The Living Marine Resources Act 1995.
