Primary 1. Optimise and calibrate STR camera configuration and deployment for scallop UWTV survey. 2. Conduct an underwater TV survey of Pecten maximus presence and density to estimate scallop abundance in selected un-dredged areas to compliment data collected as part of the wider scallop stock assessment in English Waters (priority 1 stations, Beds TV.7.f.A, TV.7.f.B, TV.7.f.C, TV.7.e.F and TV.7.d.C.) 3. Trial alternative camera platforms and deployment methods in selected areas testing video quality and frequency and quality of captured stills images as a potential candidate replacement for the main STR survey camera. Secondary 4. As time and weather permits additional survey areas described by existing dredge survey beds to survey with scallop dredges and mounted cameras to look at catch and size distribution. 5. Spatial underway sampling for nutrients and salinity for GiA03. This sampling will provide spatial winter nutrient concentrations which will contribute to the data for eutrophication assessments under OSPAR and the UK Marine Strategy. 6. Daily CALPS litter and water sampling. Narrative in attached cruise report. |
