SKQ201402S Bathymetry:Swath
Gridded bathymetry data (netCDF grid format), Jurassic Quiet Zone survey (SKQ201402S, 2014-2015)
The hull-mounted EM302 sonar system was used to collect multibeam swath bathymetry data during the 2014-2015 Sikuliaq cruise SKQ201402S to the western Pacific (chief scientists Masako Tominaga and Maurice Tivey). The processed files are in GMT-compatible netCDF grid format and have been gridded at 50m horizontal resolution. The data set was generated as part of the projects called A Deep-AUV Magnetic and Seismic Study of the Hawaiian Jurassic Crust - The Global Significance of Jurassic Magnetic Anomalies; and, A High-Resolution Deep-AUV Magnetic Survey of the Hawaiian Jurassic Basin. Funding was provided from NSF awards EAR10-29965, OCE10-29573 and EAR12-33000.
