6 Short Cruise Report, RV ATAIR, Cruise 067I041-1, Bremerhaven – Thybor?n – Aberdeen, 22 Jul – 14 Aug 2025 (WGOH) of the International Council for the Exploration of the Seas (ICES). Data from this cruise will be used for the respective ICES Report on Ocean Climate (IROC) and reporting under the Marine Strategy Framework Directive (MFSD) and the OSPAR protocol. The data will also be available for validataition of numerical operational ocean and climate models, to calibrate satellite- based ocean colour data, hyperspectral satellite data and downstream products (e.g. Secchi depth, turbidity, fluorescence, chlorophyll-a, plankton). Plankton sampling at selected stations contributes to the EnSAD project, which is part of the Environmental Mapping and Analysis Pro- gram (EnMAP, https://www.enmap.org). Pesticide data in air and water will be analysed as part of a joined collaboration between BSH and MPIC/RECETOX. Sampling and data of the Hereon group will contribute among others to the MOSES initiative and the RETAKE II project.
