Purpose
Abstract The shallow water system EM 1002 was only used during a shelf survey. Several surveys were especially designed for collecting multibeam data. During the cruise, the system was used only for water depth less than ~400. Across-track coverage is pproximately 1500 meters in deep water and up to 7.4 times the depth in shallow water. Normal angular coverage is adjustable up to 150°. During the cruise, the swath width was adjusted manually to get the best compromise between coverage and data quality with changing water depth and sea state. The beam spacing may be set to equiangular or equidistant, the latter used during MSM32
