ObjectivesObjectives

1. Sampling of fish and sediment at predefined stations.
2. Camera and video work at selected stations.
3. Fish samples will be prepared for sensory analysis and will be blast frozen on board.
4. Sediment samples will be frozen on board.

Procedure

A sampling strategy has been devised for the Elgin field that takes account of the historical and more recent surveying and seeks to determine whether the release of oil based muds associated with the incident in early 2012 is either detectable or has created a demonstrable impact in the area.

Scotia will occupy a total of 28 stations outside the 500 m safety zone of the Elgin facility at which three (3) 0.1m2 Day grabs will be obtained. Each grab will be digitally photographed, one will be sub-sampled for physico-chemical characteristics and the other two will be sieved through a 500µ and 1 mm mesh with the residue being fixed and preserved under formaldehyde. Actual station positions are presently being checked by Total Oil to ensure there is no potential for interaction with sub-sea infrastructure. As soon as these are available they will be forwarded to the vessel.

Video footage will be collected at selected stations in association with high quality digital images.

Fish samples will be obtained from four of the trawl stations originally sampled in an earlier Scotia campaign (details of the trawl tracks should be with the vessel). Fish flesh will be prepared on board the vessel and stored frozen for return to the Marine Laboratory where it will be assessed by the taste panel.

Contact will be maintained with the Elgin Platform throughout the sampling period and a representative of Total Oil will be present on the vessel.
