Appraisal of Environmental Impact and Recovery Using Laminaria Holdfast Faunas

The Sea Empress spill provided an opportunity to test the applicability of Laminaria holdfast faunal communities for detecting the pollution effects of a putative oil contamination gradient, and to assess the immediate response and consequent recovery of components of the holdfast fauna to oil pollution.

Data captured to test the applicability of Laminaria holdfast faunal communities for detecting the pollution effects of a putative oil contamination gradient, and to assess the immediate response and consequent recovery of components of the holdfast fauna to oil pollution.

Alternative Title

1996 Warwick PMSA -Appraisal of environmental impact and recovery using Laminaria holdfasts [MRCCW10000000093]

Metadata Language: English

Lineage: Four sites were chosen to reflect potentially differing levels of impact from the oil spill. The maximum length (L), breadth (nearest 0.1 cm) of every holdfast was being measured, in order to calculate the volume of each holdfast using the formula of Jones (1971). Holdfasts were broken up and sieved to collect and identify macrofauna and meiofauna. The amount of oil in the Laminaria stipes was quantified ( g oil per g algae) fluorometrically using a sycnhronous scanning (23 nm interval) technique, with yellow fuel oil as a standard Warwick and Clarke (1995). Univariate 'biodiversity' measures, termed taxonomic diversity and taxonomic distinctness used to describe community composition and structure.

The Welsh and North Devon coastal sites include: West Angle, East Angle, Dale Fort, West Blockhouse, Gateholm, Martin's Haven, Musselwick, St. Brides, Abereiddy, Porth Gain, Aber Draw, Abercastle, Hartland Quay, Welcombe Mouth, Morwenstow, Duckpool. Monitoring and impact assessment following the Sea Empress oil spill.
