    Description

    This dataset is comprised of a collection of marine species sightings collated since 1993 from marine surveys, technical support contracts and research, and monitoring contracts. This dataset is currently maintained and managed by Natural Resources Wales (NRW). The surveys focus on benthic habitats (often referred to as 'biotopes') in intertidal, inshore (typically within 3 nm) and subtidal areas. Original copies of all the surveys are now held in NRW's Marine Recorder database.

    Purpose

    The purpose of this data capture was to aid coastal zone and sea-use management and to contribute to the identification of areas of marine natural heritage importance.

    Methodology

    Quality control

    High. The majority of surveys are carried out by an experienced marine biologist. Volunteer surveys are checked by NRW staff. Historical data, however, may have lower precision and accuracy and may not be verified.

    Method steps

    1. The contract surveys were collected according to different methodologies. These include methods described in the Marine Nature Conservation Review (MNCR) Rational and methods report and Countryside Council for Wales' (CCW) marine monitoring techniques described in CCW Contract Science Report No: 380 (Sanderson et al, 2001). As of April 1st 2013, data is held and managed by Natural Resources Wales (NRW).
