Purpose | |
Abstract | SO148 was dedicated to detailed analysis and measurements at vent sites with active fluid and bubble discharge. While SO148-2 addresses geophysical, biogeochemical, and hydrographic processes associated with fluid venting from the Cascadia continental margin, specifically the processes resulting from the methane hydrate dynamics at Hydrate Ridge. Multibeam swathmapping was almost continuously recorded during RV SONNE cruise S0148. Hydrate Ridge as the main target area was intensely measured during former cruises. Therefore, the measurements were focussed on gaps between the R1 structure and Hydrate Ridge. |
