2. To "ground truth" the area using a towed sledge with underwater TV camera, and with stills photography. 3. To collect sediment samples using a Day grab to establish the type of substrate in each sub-area. 4. To repeat 1-3 above (if time permits) on Race Bank where there is an extensive crab fishery and where ovigerous female crabs are thought to be present. |
