PurposeResearch
ObjectivesThe scientific aims for D340 Leg B were:
1. to study the physical response of tidal flows to topographic features of the shelf seas to the west of Scotland, in terms of stratification and turbulent mixing
2. to study the consequent response of the water column chemistry and phytoplankton community structures
3. to study the benthic response of the hard coral reefs systems commonly found in this area.

This cruise was funded under Theme 3 of NERC's Oceans2025.
