Samoa Bathymetry 70m 2004

The Pacific Islands Applied Geoscience Commission (SOPAC) carried out a marine survey
for Samoa around the islands of Savai’i and Upolu. The objective was to investigate the
seabed and provide information about water depths around the islands using a Multibeam
echosounder (MBES).

The survey achieved 100% coverage of the seafloor from approximately 50 m depth in the
nearshore area to an average offshore distance of 10 km, reaching water depths of some
1500 m. Coverage was significantly less in some areas such as Apolima Strait.
