Ziel der Reise / Objectives of Cruise:
Dana 9-21: The cruise was part of the ICES co-ordinated International Herring Larvae Surveys (IHLS) in 2021/22. The aim is to estimate the distribution and abundance of North Sea herring larvae for assessment purposes. The larvae samples are taken on a standard grid with a station to station distance of approx. 10 nm. Used gear is a modified GULF plankton sampler (Nackthai). Area under investigation was around UK-Scotland and the Orkney-Islands. Sampled were collected on 105 stations. The cruise was conducted as schedule, with some adaptations of the work plan according to unfavourable weather conditions.
