Habitat point records from 1991 NRA Southampton Water sublittoral survey

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.本研究采用面积为0.1平方米的Day Grab采样器（Day Grab），在南安普顿水域（Southampton Water）的三个不同采样点采集抓斗样品，同时也获取了颗粒度样品（granulometric samples）。研究人员在塞尔西比奇（Selsey Bill）使用锚式拖网（anchor dredge）开展底栖生物（benthos）采样，但该部分数据未被纳入本数据集，原因在于其仅能提供半定量数据，且采样区域超出了本次区域总结的覆盖范围。注意：本次调查于1991年4月开展，为便于数据录入，统一将采样日期标注为当月1日。
