The product of a bathymetric study is usually a topographic map of the floor of the subject water body. Early bathymetry consisted of lowering cables to measure the depth to bottom, with such technology being driven by needs for navigational safety. In the twentieth century acoustical soundings began to be used to explore the sea bottom for a wide range of oceanographic research purposes.
