Ziel der Reise / Objectives of Cruise:

The three objectives of R/V POSEIDON`s transit cruise POS421 from Kiel, Germany, to Las Palmas, GC, Spain, were: - check underway temperature and salinity measurements of the ship`s underway data acquisition system and, if data were reasonable, to provide these data as TRACKOB via the German Hydrographic Office (BSH) to the international GTS operated by the World Meteorological Organization and the International Oceanographic Commission (IOC) of the UNESCO through the Joint Oceanographic Commission (JCOMM). - calibrate underway measured salinity in delayed mode by comparison with in-situ surface water sampling - test if salinity as derived from directly measured near surface sound velocity and temperature is suitable as a back-up and long-term stability control for salinity as measured with the more precise standard thermosalinograph
