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.

对旋棘珊瑚（俗称ross worm）礁的调查持续全年进行。数据收集采用声学底质识别系统调查、抓取采样以及遥控潜水器调查相结合的方法。绘制礁区的地图是条件评估（针对Wash和North Norfolk Coast SAC，其中Sabellaria珊瑚礁是关注的特征）的一部分，并为该区域的渔业管理措施提供信息。Wash区域内有多个区域被调查；更多关于调查方法的详细信息请参阅谱系。
