Summary

The aim of the survey was to provide a broad scale assessment of the sandeel distribution across Tranches A and B of the planned Dogger Bank offshore wind farm; establishing the abundance, species composition and distribution of sandeel species within the area. 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
