Estimation Method of Bottom Sediment Type in the Jiaozhou Bay Based on the Bathymetric Data
Dewen Du, Xuefa Shi · Haiyang kexue jinzhan · 2004
In this paper, the bottom sediment classification method by using high precision multibeam bathymetric data is discussed. The statistical characteristics for specified sampling window units are extracted from the bathymetric data, and the cluster analysis method is then used to classify the sampling window units. The classified results are compared with the surface bottom sediment survey results and the multibeam sonar classified results, and it is shown from the comparison results that the three kinds of results are consistent with each other. Therefore, the estimation method can be used to identify different bottom sediment types such as bedrock, gravel, sand and clay.
