    "description": "The Sea Empress oil spill in February 1996 affected the water column, seabed and shores of south Pembrokeshire. Several rocky subtidal sites in and around the entrance to Milford Haven were studied at the time of the spill. This datasets is made up of the results obtained during a subtidal survey of South Pembrokeshire 16 months after the Sea Empress oil spill. The survey aimed to examine the open coast of South Pembrokeshire sites close the entrances of Milford Haven, as far eastwards as Caldey Island. The objective of this work was to revisit previously surveyed bedrock areas which may be have been subjected to elevated water column hydrocarbon load in order to investigate their community diversity, richness and condition.",
