Intern:Ships track

Ships track data are any measurements carried out along the cruise track while the ship is moving. Data might include:
 * Temperature/salinity (thermosalinograph)
 * Weather observations
 * Current meter (ADCP)
 * Extended bathythermograph (XBT)
 * Gravity
 * Magnetic
 * Seismic & echo sounding (Pangaea import file includes metadata with link to files)
 * Reflection seismic
 * Refraction seismic
 * Bathymetric echo sounder
 * Swath sonar (e.g. HydrowSeep, SeaBeam)
 * Sediment echo sound (e.g. ParaSound)
 * Fish sounder

Format specifications
Data matrix consist of the following columns:
 * Event label (Event label = cruise label-"track")
 * Date/Time (1599), in a valid date/time format
 * Latitude (1600), in decimal degree
 * Longitude (1601), in decimal degree
 * Speed [kn] (2960)
 * Course [deg] (2961)
 * Data or links to files


 * for undefined values leave cell in data matrix empty (do NOT use values like -9999.99)
 * exclude outliers and/or use quality flags
 * avoid system specific file protections
 * provide one citable protocol for data conversion and quality control per cruise in pdf/a-format
