| Objectives | Objectives
1. To map spatial distribution of sediment characteristics, infauna composition, pore-water nutrients and organic matter content within the inner Firth of Clyde, Clyde sea lochs and Clyde Estuary. 2. To map the relationship between mean particle grain size and permeability/porosity in the Firth of Clyde. 3. Determine how relationships among sediment properties and sediment nutrient content are modified by natural disturbance, fishing activity and bioturbation potential. Procedure Stations are stratified according to depth and sediment mud content. Stations in the Clyde Estuary and in the vicinity of the isles of Bute and Cumbrae will be sampled Day 1 (13 October). Subsequent sampling days will then focus on sampling stations south of Bute and east of Arran, and stations west of Bute and in Loch Fyne. It is expected that ~ 5 stations will be sampled per day. The survey anticipates equal emphasis on grab sampling and coring. The target would, therefore, be six cores, two grab samples and one CTD profile from each station. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
