|Cruise period||2003-07-25 — 2003-08-04|
|Port of departure||Lowestoft, United Kingdom|
|Port of return||Lowestoft, United Kingdom|
|Objectives||1. To conduct sampling at a relinquished marine aggregate extraction site at Coal Pit/Sole Pit (Area 408) using trawl, underwater TV and acoustic techniques for time series studies to establish the time required for recovery of the sea bed fauna.
2. To conduct surveys at a relinquished aggregate extraction site off Harwich (Area 222) using grab, underwater TV, trawls and acoustic techniques for time-series studies to establish the time required for recovery of the sea bed fauna.
3. To conduct a habitat mapping survey between the Varne (off Dungeness) and the Hastings Shingle Bank. The survey will employ various tools including grabs, trawls, underwater TV and acoustic techniques with a view to further development of habitat mapping techniques.
4. To conduct surveys at the Hastings Shingle Bank (Areas X and Y) using grab, underwater TV, trawls and acoustic techniques for time-series studies to establish the time required for recovery of the sea bed fauna.
5. To conduct grab sampling within an area of the current Hastings Shingle Bank aggregate extraction licence with a view to identifying indicators of environmental disturbance.
6. To conduct grab sampling in the vicinity of the Hastings Shingle Bank in order to characterise a number of areas of seabed previously identified using various acoustic techniques.
