Cruise summary report
| Cruise Info. | |
| Ship name (ship code) | RV Corystes (74RY) |
| Cruise identifier | COR10B/97 |
| Cruise period | 1997-10-07 — 1997-10-13 |
| Status | Completed |
| Purpose | Research |
| Objectives | To survey of areas subjected to different intensities of fishing in the Irish Sea using a combination of the following techniques
1) Side-scan sonar survey to ascertain the comparability of substratum type in areas used for comparative studies, and to ascertain the recent intensity of fishing in those areas 2) Sample the epibenthic community within specific areas using repeated tows (3-5 min duration) of a 2 m beam trawl fitted with a stills camera to obtain images of the seabed and quantitative estimates of epifauna 3) Collect specimens of live bivalves at each station using an anchor edge dredge for determination of historical fishing intensity which can be related to the communities in aim 2 (NP0309) 4) Collect sediment samples at each station using a Day grab for sedimentological analysis 5) Record the occurrence and damage rate of starfish and retain them for laboratory analysis. Retain live bivalves for laboratory growth studies to ascertain the rate of repair of damaged shells 6) RoxAnn and the new QTC system will be run in parallel to compare which gives the best prediction of community type |
