Samoa, South Savai, 2004, Bathymetry Chart No: 9, 1 to 50 000 #2

This record holds the bathymetry chart of the Southern foreshore areas of Savaii, Samoa. The chart is the result of the multibeam bathymetry survey that was undertaken by the Applied Geoscience and Technology Division (SOPAC) of SPC around the islands of Upolu and Savai for the EU-SOPAC Samoa Survey. High-resolution bathymetric mapping survey was carried out ,resulting in the acquisition of over 2754 line-km of MBES data for the whole of Samoa Survey. The entire survey achieved 100% coverage of the seafloor from approximately 50 m depth in the near-shore area to an average offshore distance of 10 km, reaching water depths of some 1500 m. The resultant data compilation was used to produce bathymetry charts and XYZ datasets available from a separate record . This work was initiated by the SOPAC/EU Reducing Vulnerability of Pacific ACP States Project (Task no.: NR 1.1.1). The result of the survey conducted in this area is presented as Chart 9 of the Samoa High resolution bathymetric survey and can be downloaded from this record under the Distribution Info section with appropriate permission from the Secretariat.The bathymetry chart also includes smaller-scale insets of 3D images, slope angle and shaded relief maps.The objective was to investigate the seabed and provide information about water depths around the islands using a multibeam echo sounder (MBES).DESCRIPTION of MORPHOLOGICAL FEATURES on CHART 9The shelf south of Savai’i is relatively narrow, with the break occurring approximately 2 km offshore. The shelf slope exhibits an average angle of around 35 degrees, and is incised by some minor channels.
