The purpose of this data capture was to create a dataset to help with an evaluation of the deployment of drop-down video for identifying biotopes. Footage collected as an assessment of using drop-down video as part of a site-orientated monitoring technique. Data was gathered as a result of the development and trial of a remote drop-down video-based monitoring method to measure biotope richness. Data was collected from two sites that presented sufficiently different physical conditions and biological conditions- north Pen Llyn reefs, and Sarn Badrig reef.

dataset
The method development and trialling carried out during this survey was a precursor to the across Wales drop-down video monitoring work undertaken in 2004-05. The video was subsequently re-analysed in April 2012 by CALM and the data held in Marine Recorder replaced. Drop-down digital video-based monitoring gear, deployed from a 7.5m aluminium RIB. Species and habitat data entered into Marine Recorder. Data collected for primarily for method validation purposes. See sections 2.1.3 and 3.1.2 of the Marine Monitoring Report. Analysis of the video for it's biological and physical attributes was undertaken by Aquascan Ltd in 1999. The video was subsequently re-analysed in April 2012 by CALM and the data held in Marine Recorder replaced.
