SeaStar complete phase 2 of the Alderney South Bank Survey
19 May 2011
SeaStar Survey Ltd have made use of the settled weather conditions in April and May to complete the second phase of the South Bank survey.
Using a Kongsberg OE 14-206 dropdown video and stills camera they have completed 27 video transects of the bank totalling nearly 6 hours of seabed video footage and 270 close-up photographs of the seabed. Grab samples of soft sediment from the Bank have also been taken for analysis from 8 selected sites.
The final phase of the survey will be to measure the maximum spring tide current flows over the Bank using a hull mounted Acoustic Doppler Current Profiler (ADCP) measuring device.
