PurposeResearch
Objectives1. To obtain dual frequency echosounder data from a survey line extending from west of Colonsay, through the Firth of Lorne and Loch Linnhe, to Fort William.
2. To obtain samples of macrozooplankton using the Methot Isaacs Kidd net for comparison with the echosounder data.
3. To obtain plankton and hydrographic data using the Autosampling and Recording Instrumented Environmental Sampler (ARIES).
