| We analyzed the acoustic data obtained with a multibeam echosounder during an oceanographic survey abroad the “R/V Miguel Oliver” in january-february of 2010. The aim was mapping the sea floor of the continental slope of the uruguayan Exclusive Economic Zone (EEZ). The acoustic data were processed with MB-System software, and then incorporated into a Geographic Information System (Quantum GIS). We obtained 3 m for 3 m grid files to describe small submarine structures (mounds and pockmarks), and also a topographic map of the entire area to describe large submarine structures (submarine canyons and landslides). When we analyzed the topography of the entire area we identified 4 submarine canyons and the beginning of a fifth in the south end. We also observed... |
