This thesis used a combination of sediment, coral, fish, climatic, and oceanographic data, and focused on the Pohnpei Lagoon, examining a range of natural and human issues in the marine environment both at the local level (focusing on that within the Pohnpei Lagoon) and regional level (focusing on the western Pacific region).
This report describes the high-resolution bathymetric mapping survey carried out in 2004. The survey achieved good coverage of the seafloor from approximately 10 m depth in the nearshore reef slope area, to an average offshore depth of some 2000 m, at an average slope angle of 2. The objective was to investigate the seabed and provide information about water depths around the islands using a multibeam echosounder (MBES).
