摘要
在典型的实验海区,使用双频测深仪和箱式取样器,对海底进行同步探测,获取双频测深仪不同底质类型数据。比较了式取样器海底底质样品,归纳出海底基岩、沙、粘土的双频测深仪水深数据和双频测深仪海底模拟记录图象特征,该特征可为双频测深仪识别海底底质类型提供先验认识。
Simultaneous bottom characteristics surveys were made by using dual-frequency echo sounder and box corer in an experimental sea area, and the bathymetric data and samples for different types of bottom material were obtained. The digital bathymetric data and analog record characteristics for bottom bedrock, sand and clay were derived by comparing the bathymetric data with the bottom material samples, and these characteristics can provide a priori knowledge for identifying the bottom material type by using dual frequency echo sounder.
