Purpose | All surveys done using the Seabeam 3050 were designed for bathymetry acquisition and/or bubble mapping (AKA, water column imaging). |
Abstract | At cruise POS462 multibeam surveys were made using the multibeam echosounder (MBES) available at R/V POSEIDON. The system is from ELAC NAUTIK. It is a 1.5-by-2-degree mid-water MBES operating with a frequency of 50 kHz and a maximum number of beams of 384. This equipment is designed for mapping until 3000 meters depth but due to unknown reasons (perhaps ship noise or something else) the maximum range we could achieve was around 2000 m. The maximum swath coverage at the depth ranges between 1200 and 2000 m was of around 1 (or 2 at the shallow parts) time the water depth. But this is in agreement with the official performance calculations done by ELAC. |
