Seasearch Marine Surveys in Wales

This dataset consists of habitat and species records made by volunteer scuba divers. The data from 1983-1987 comprises sub-littoral surveys carried out by members of the Marine Conservation Society. The data from 1988-2000 comprises data using the initial Seasearch methodology by members of the Marine Conservation Society and associated organisations. The data from 2001 onwards has been collected using the revised Seasearch methodology which has two main levels of detail. The Observation Form level provides a single sample containing habitat and species data from each site. The Survey Form level provides multiple habitat and species lists. This data has been collected from dives organised by the Marine Conservation Society, Seasearch, dive clubs and individuals. Data has been entered by MCS and is freely available.

本数据集由志愿水肺潜水员记录的栖息地与物种观测数据组成。1983年至1987年的数据为英国海洋保护协会（Marine Conservation Society, MCS）成员开展的亚潮带（sub-littoral）调查成果。1988年至2000年的数据，则采用初始版海洋搜索（Seasearch）调查方法，由英国海洋保护协会及其关联机构成员采集。2001年起的所有数据均采用修订版海洋搜索（Seasearch）调查方法，该方法包含两个主要细节层级：其一为观测表（Observation Form）层级，每个调查点位仅提供一份包含栖息地与物种信息的单样本数据集；其二为调查表（Survey Form）层级，可提供多组栖息地与物种名录。本数据集的数据采集自MCS、海洋搜索、潜水俱乐部及个人组织的潜水活动，由英国海洋保护协会完成录入，且可免费公开获取。
