ROV Dive S0469 - Scarp offshore of Isla Espiritu Santo

Join ROV SuBastian from the RV Falkor for the eight dive of the Interdisciplinary Investigation of the Pescadero Basin geology and morphology of the east margin of the Baja California Peninsula reflects the continental rifting that has created the Gulf of California, ultimately resulting in the several en echelon basins we have been studying. These rifting processes have included low angle normal faulting that has left behind many blocks of the pre-existing continental crust that have been broken up, tilted, and rotated. Ron Spelz (Chief Scientist of Leg 1) and his students are studying these aspects of the rifting history, and wish to test hypotheses about the formation of the many topographic highs between the Baja east coast and the deep basins. This dive will attempt to sample rocks on the steep eastern scarp of a topographic high located about 24 km east of Isla Espiritu Santo. This short dive will occur early in the morning during the transit in to La Paz (Puerto Pichilingue) ending FK210
