PurposeTrials
ObjectivesThe purpose of the cruise was the evaluation of the new vessel and its scientific equipment under scientific and technical aspects with a focus on the CTD water sampler and the different integrated underway sensors. A secondary objective is the realistic scientific operation of geophysical and bio-optical instruments on board as training for future scientific expeditions. On board systems for deployment of geophysical instrumentations (e.g. winches, etc.) were evaluated. The scientific objectives are (a) the bio-optical characterisation of water bodies from the North-West European Shelf and the North-East Atlantic and (b) the investigation and comparison of water mass composition.

The following methods/activities were done:
(a) Sampling and testing of different underway systems utilising a ferrybox system, a remote sensing reflectance setup and various laboratory validations.
(b) Bio-optical stations with CTD profiles, bio-optical sensor assembly profiles, radiometer-profiler operations and Secchi disk recording.
(c) Deployment and testing of geophysical instruments (CSEM systems, magnetics, gravimeter)
