Purpose

Objectives

1) To conduct a spring 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 is undertaken by measuring the following parameters at multiple stations in each loch:
a. CTD, dissolved oxygen and transmission
b. Nutrients (inc silicates)
c. Chlorophyll a
d. Phytoplankton
e. Shoreline macroalgae
f. Organic carbon in sediments
g. Algal toxins in wild shoreline mussels, phytoplankton and water
These determinands will be assessed against criteria as defined by the OSPAR Eutrophication Task Group 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.
2) Zooplankton to be sampled by bongo net from two hydrostations in each loch and fixed in ethanol and formalin.
3) Sediment samples to be obtained by Day grab from 12 lochs and retained for phytoplankton cyst analysis by Phytoplankton Ecology group.
4) Passive sampler for water-borne contaminants to be deployed at four separate sites in Shetland for 8-12 hours to trial new sampling methodology.
5) Water samples for radioisotope analysis will also be taken from CEFAS collection sites in the Pentland Firth and Minch on an ad hoc basis when steaming between survey areas. Sampling is via the non-toxic supply into 25L carboys and 1L polybottles.
