Habitat point records from 1997 AES River Parrett (Severn Estuary) sediment survey

The River Parrett falls within the boundary of the Severn estuary pSAC. Until this survey no marine biological survey had been undertaken in the river. This survey was undertaken, under contract to MNCR, JNCC, specifically to provide infaunal information for the sediment communities in suppport of the designation and management of the site. 10 littoral sites were surveyed using standard MNCR methodology (8 x 10.3cm cores at each site, seived over 0.5 mm mesh). Sublittoral samples were taken using a hand held Van Veen grab (x2 grabs were taken at each site to give a combined sample area of 0.1m2).

帕雷特河位于塞文河口保护区域（pSAC）的边界之内。在此调查之前，该河段尚未进行过海洋生物调查。此次调查是根据MNCR、JNCC的合同进行的，旨在为该区域的指定和管理提供底栖动物信息。共对10个沿岸地点进行了调查，采用MNCR标准方法（每个地点采集8个直径10.3厘米的柱状样，并通过0.5毫米的筛网筛选）。使用手持式范·温抓斗采集了海底样品（每个地点采集2次，以获得总面积为0.1平方米的混合样品）。
