Marine data from Natural Resources Wales (NRW) Technical Support (Research & Monitoring) Contracts, Wales

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.
