JC066 Bathymetry:Swath
Processed bathymetry data (netCDF grid format) of selected seamounts along the Southwest Indian Ridge, James Cook cruise JC066, 2011
The Southwest Indian Ridge seamount bathymetry data was collected with a hull-mounted EM120 sonar system in 2011 during James Cook cruise JC066 (chief scientist Alex David Rogers). The gridded bathymetry files have a 20m x 20m horizontal resolution and cover the areas of Atlantis bank, Coral seamount, Melville seamount, Sapmar seamount and "Middle of What" seamount. The files are in GMT-compatible netCDF grid format. They were constructed by editing the data and then using MB-SYSTEM command "mbgrid". Funding for the work was provided through a UK-NERC grant.
