Cruise identifier

0702C

Cruise period

2002-04-26 — 2002-05-09

Status

Completed

Port of departure

Fraserburgh, United Kingdom

Port of return

Fraserburgh, United Kingdom

Purpose

Research

Objectives

To conduct a 'spring' survey of a suite of sea lochs impacted to varying degrees by nutrient releases from fish farming activity. This survey will form part of a 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
2. Nutrients and silicates
3. Chlorophyll
4. Phytoplankton
These determinands will be assessed against criteria as defined by the OSPAR Eutrophication Task Group.
