Such a survey was done before oil from the tanker SeaEmpress hit the Welsh coast in 1996, and made it possible to monitor the quite pleasing speed of the recovery.
However, this can cause many problems. In 1 996 the ship, The SeaEmpress, ran aground spilling an estimated 70,000 tonnes of oil which has contaminated much valuable natural Welsh coastline.
