Status

Completed

Port of departure

Fraserburgh, United Kingdom

Port of return

Fraserburgh, United Kingdom

Purpose

Research

Objectives

1. To conduct a hydrographic survey along a transect offshore of Stonehaven. At pre-selected locations, the Seabird CTD sampler and the dual Bongo net will be deployed using a vertical dip. Water samples will be collected for salinity, nutrient and phytoplankton analysis. The 1 m plankton net will be deployed using a double oblique tow between selected stations along the transect.
2. To investigate the density distribution of sandeels buried in the sediment 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.
3. 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.
4. 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.
