|Ship name (ship code)||FRV Clupea (74CU)|
|Cruise period||2002-03-21 — 2002-04-01|
|Port of departure||Fraserburgh, United Kingdom|
|Port of return||Fraserburgh, United Kingdom|
|Objectives||1. To lay three hydrographic monitoring moorings, one near the Stonehaven transect, and two in the Wee Bankie/Marr Bank study area.
2. To conduct hydrographic survey along a transect offshore of Stonehaven. At preselected locations the Seabird DTC sampler and the dual Bongo net will be deployed using a vertical dip. Wster samples will be collected for salinity, nutrient and phytoplankton analysis. The 1m plankton net will be deployed using a double oblique tow between selected stations along the transect.
3. To investigate the density distribution of sandeels buried in the sediement by carrying out a nocturnal stratified random Day grab survey across the Wee Bankie/Marr Bank study area. All sandeels caught will be measured, weighed and have their otoliths collected.
4. To investigate variation in sandeel population age structure at different locations on the Wee Bankie and Marr Bank from samples collected using the Sandeel dredge.
5. To determine spatial variation in water temperature and salinity across the Wee Bankie/Marr Bank study area using a Seabird CTD sampler. Approximately 40 vertical dip stations will be sampled utilising as far as possible the day grab survey stations.
