Grab samples were taken using a 0.1 m^2 Day Grab at three different sites in Southampton Water. Granulometric samples were also taken. An anchor dredge was used to sample the benthos at Selsey Bill but this has not been included as it provides only semi-quantitative data and is outside the boundaries of the area summary. N.B. Survey took place in April 1991. The first of the month has been given for input purposes.
