Abstract | SO173-4 was dedicated to geochemical, sedimentological, biological, and oceanographic measurements and sampling as well as video sled and lander-based seafloor observations and measurements of the most of the newly discovered mounds on the Nicaragua and Northern Costa Rica margin. The EM120 was used continuously during SO173-4. During deep tow profiling dense line offset was used to reduce the opening angles of the beams in order to receive higher resolution images while still covering the complete area. At the beginning of the cruise, a water velocity profile was measured to a depth of 2000 m. |
