Loch Linnhe and Loch Eil, west coast of Scotland

Dissolved oxygen parameters in the water column; Insect and earthworm taxonomy-related abundance per unit area of the bed; Salinity of the water column; Quantity of material dumped; Redox potential in sediment; Concentration of other organic contaminants in sediment samples; Concentrations of biopolymers in sediment; Temperature of the water column; Alkalinity, acidity and pH of the water column; Nitrogen concentrations in sediment; Carbon concentrations in sediment; Fauna abundance per unit area of the bed

Discrete water samplers; sediment grabs; unconsolidated sediment corers

The survey was initiated to assess the impact on the sedimentary ecology of the area of the effluent from a pulp and paper mill discharging into the narrows between the two lochs. It was continued as a general study of organic enrichment of marine sediments and of fjordic benthic ecology. The study resulted in the publication of over 50 research papers over a period of 20 years.
