This series of digital terrain models (DTM) of the South East Pacific Ocean has been created from a compilation of multibeam bathymetric data acquired during 18 cruises of German (RV Sonne, RV Meteor), British (R.R.S. James Cook) and Chilean (RV Vidal Gormaz) research vessels between 1995 and 2012. The multibeam data has been carefully reprocessed taking into account available water sound velocity profiles and manually edited (artifacts and outlier removal). The DTMs have been calculated on a regular grid with grid cell sizes of 200 m by 200 m. Grid calculations have been done using the MB-System software (http://www.ldeo.columbia.edu/res/pi/MB-System) by the program mbgrid using a Gaussian weighted mean gridding algorithm. Grid cells holding no data have been set to NaN (not a number). The grids are provided in netcdf-format (http://www.unidata.ucar.edu/netcdf) ready to use with the GMT- (http://gmt.soest.hawaii.edu/) or other plotting software. For detailed information about the map sheets see the further details link.
