PurposeResearch
Objectives1. To track and sample a drifting patch of larval haddock on the shelf north of Shetland and sequentially sample their vertical distribution, zooplankton prey distribution and abundance, and abiotic environment.
2. To obtain some data on the wider distribution of larvae and plankton across the shelf and into the Faroe-Shetland Channel.
