Species point records from 1991 NRA Blackwater Estuary sublittoral survey

Twenty one sublittoral sites on the River Blackwater estuary were surveyed in July 1991. Three replicates of 0.1 square meters were taken at each site using a Day Grab. Each sample was sieved through a 0.5mm sieve. Sediment analysis was carried out on each sample. Records currently considered sensitive have been removed from this dataset.
