In addition, the survey objective was to define the east-west boundaries of the areas of high sandeel densities along the western boundary of the Dogger Bank Zone and in its central area as implied by Danish sandeel fishing activity, defined by VMS satellite tracking and by Jensen et al. (2011).This was undertaken between the 22nd March and 1st April 2012. A conductivity temperature and depth (CTD) probe was also used to record temperature and salinity depth profiles at every tenth station(weather permitting). The times, co-ordinates, depths and locations of each deployment of the CTD probe are given in the Sandeel survey report. 47 tows of approximately 250m were undertaken within Tranche A, 20 tows were undertaken in Tranche B and a further 43 control tows were undertaken in adjacent areas. Sandeels require the presence of a specific substrate in which to burrow and it is understood that sandeel distribution and spawning grounds will occupy discrete patchy areas rather than be continuous throughout the Dogger Bank Zone. As such the sampling effort was primarily concentrated over known fishing grounds, with areas outside these being sampled less intensively. This series contains a survey report and GIS shapefiles.

The dredges, steel bellies and nets were manufactured using the specifications obtained through consultation with H. Mosegaard (DTU Aqua) and at a meeting with MSS, with the gear technician responsible for constructing the sandeel dredges used for MSS survey works.
