Brief description
This data was collected to assess the impact of a saline wastewater discharge outlet from a power station that commenced discharging in mid 1983. Infaunal samples were collected from an impacted location (McGaurans Beach) and 2 control locations at Woodside Beach at depths of 3 to 15m. There were five sites within each location and each site was sampled annually from 1982 to 1986. This sampling covered 15km of coastline near 90 Mile Beach and lay within the stretch of coastline covered by the Latrobe Valley Ocean Outfall (LVOO) program.Lineage

Statement: Sediment samples were collected using a diver-operated suction sampler. At each sampling site, a 0.125m2 cylindrical quadrat was pushed into the sediment to a depth of 10cm, and the enclosed sediment sucked into a mesh bay of 710 µm sieve size. The quadrat was randomly repositioned, and the sampling process repeated, to collect 3 replicate samples at each site. Replicate samples at each site were pooled into a single sample and preserved on site in a buffered 10% solution of formalin in seawater.
In the laboratory, samples were stained with Rose Bengal to highlight biological material. Infaunal organisms were removed from the sediment under and low-power magnifying lens and then identified and counted using a binocular dissecting microscope. All samples were identified to species levels with the exception of nematodes and nemerteans.
