2005 - Ongoing, EIFCA (Eastern Inshore Fisheries and Conservation Authority), The Wash, Sabellaria spinulosa reef (habitat mapping) surveys

Sabellaria spinulosa (ross worm) reef surveys are carried out continuously throughout the year. Data is collected using a combination of Acoustic Ground Discrimination System surveys, grab sampling and Remote Operated Vehicle surveys. Mapping the reefs forms part of the condition assessments (for the Wash and North Norfolk Coast SAC for which Sabellaria reef is an interest feature) and informs fisheries management measures for its protection.
Several areas within the Wash are surveyed; please see lineage for more details on the methodolgy.

Sabellaria spinulosa（刺毛珊瑚虫）礁的调查工作全年持续进行。数据收集采用声学底质识别系统调查、抓取采样和遥控潜水器调查等多种方法相结合。绘制礁区地图是条件评估（针对Wash和North Norfolk Coast SAC，其中Sabellaria礁为关注特征）的一部分，并为该区域的渔业管理措施提供信息。 Wash区域内多个区域进行过调查；有关调查方法的详细信息，请参阅谱系。
