BSH Delphin, since 2009 an EIVA MK2 ScanFish) was deployed which oscillated between
surface and bottom to record the distribution of relevant oceanographic parameters with high
resolution in space and time (24 Hz). Both CTD-systems are recording temperature, salinity,
fluorescence (chlorophyll-a, yellow substance), and oxygen concentration. Additionally, ship-
mounted temperature-, salinity- and optical sensors provided data at about 4 m depth. In
order to sample the transition area between North Sea and Atlantic the survey was expanded
northwards to 62.5°N since 2010.
The objective of the NSSSs is the assessment of the oceanographic and chemical state of
the North Sea, the calculation of heat and salt budgets, and the identification of changes due
to climate change. The data are also used for the validation of operational and climate
models and for the calibration of satellite-based ocean colour data and downstream products
(Secchi depth, turbidity, CDOM, chlorophyll-a) which are used for assessments and MSFD
reporting. All NSSSs are listed in Table 1. Most of the data are available via the German
Oceanographic Data Centre (DOD) and the MEris MAtchup In-situ Database MERMAID.'
