Comment:
The swath sonar bathymetry data were acquired as part of the project AISTEK-II during SONNE cruise SO183. The data were sampled using the multibeam sonar system Simrad EM 120 from Kongsberg, which operates on a frequency of 12 kHz, maximum swath width of 150 degree and 191 preformed beams. Mean sound velocity was gained from six sensor CTD measurements acquired during the cruise. Ship position was measured by GPS and DGPS, ship orientation by gyrocompass. The density and quality of depths were decreased during bad weather conditions. Raw data are delivered within Simrad format. XYZ data files are provided in addition, derived from edited data and containing a time period of 8 hours each.
Stylesheet for viewing the xml metadata files is available at http://hs.pangaea.de/bathy/so183/fgdc_bat_awi.xsl
Data are also provided as xyz-values (ZIP, 635 MB) - see "Other version". Contact infobathy@awi.de for data access.
