Marine and Coastal Access Bill [HL]

On the question of mapping raised by the noble Baroness, Lady Miller, in chairing the Joint Committee I had the advantage of being present all the time. She may not have been there when one of our expert advisers showed us that, as I understood it, the basic knowledge of the seabed is much more widespread than any of us thought at the time. We are lacking the detailed work that requires special techniques. That is very expensive, as we need ships with side scan sonar and all the rest. However, basically we have a good idea what happens on the seabed, although we are lacking the detail, which will take time to get.
