AT11-20 Bathymetry
Processed Near-bottom Bathymetry Data (ASCII format) derived from Scanning Altimetric Sonar Data from the East Pacific Rise at 9N acquired with HOV Alvin during the Atlantis expedition AT11-20 (2004)
This data set was acquired with an Imagenex 881 Scanning Sonar on the HOV Alvin during Atlantis expedition AT11-20 conducted in 2004 (Chief Scientist: Dr. Marvin Lilley). These data files are of Text (ASCII) format and include Bathymetry data that were merged with navigation and processed after data acquisition. Data were acquired as part of the project(s): Biocomplexity: Smart Sensors for In Situ Monitoring of Hydrothermal Vent Systems, Establishing a Role for Fe and S Microbial Metabolism in Ocean Crust Weathering, Time-Series Larval Studies in the Deep Sea, and The Interaction of Microbial Biofilms and Fluid Chemistry on Larval Settlement, and funding was provided by NSF grant(s): OCE01-19999, OCE02-41791, and DOEI.
