Objectives

Objectives

To conduct a 'late summer' survey of a suite of sea lochs / voes impacted to varying degrees by nutrient releases from fish farming activity. This survey forms part of an ongoing programme of work to assess the potential for eutrophication arising from nutrient 'hotspots' linked to aquaculture. This will be undertaken by measuring the following parameters at multiple stations in each loch:

1. CTD and dissolved oxygen
2. Nutrients (inc. silicates)
3. Chlorophyll a
4. Phytoplankton
5. Shoreline macroalgae
6. Organic carbon in sediments
7. Algal toxins in wild shoreline mussels, phytoplankton and water

These determinands will be made available for assessment against criteria as defined by the OSPAR Eutrophication Committee and used for future eutrophication assessment of Scottish coastal waters. Data will also be compared to that collected during previous cruises and will be used to inform estimates of internal mixing within sea lochs/voes to improve laboratory models to predict nutrient enhancement from aquaculture.

In addition zooplankton will be sampled by bongo net from 1-2 stations in each loch and fixed in ethanol and formalin.

Sediment samples from close to fish farms will also be taken to determine the levels of metals, organic carbon and persistent organic pollutants.

Surface chlorophyll a levels will be recorded by continuously recording flourometer, within a tidal excursion close to two large open water fish farms during a 12 hour tidal cycle.

Narrative

Scientific staff boarded the vessel at 1000 on the 28 August and after securing scientific gear, Clupea sailed for the Beatrice field. Here two CTD casts were undertaken in the NE corner of the field to record dissolved oxygen levels in response to recent reports of dead invertebrates in trawls following an algal bloom in the area.
