Sub-surface towed video footage off North Pen Llyn, and subsequent biotope identification data

  • English

  • All

This dataset is a collation of around 5 hours of digital video footage. Positional and other associated data are given in Sanderson et al., (Eds.) 2001 (CCW Marine Monitoring Report No.1, section 2.1.3, and data appendix). The purpose of the data capture was to create an evaluation of the deployment of towed video for monitoring biotope richness. Footage collected as an assessment of using towed video as part of a site-orientated monitoring technique. Following the increased commercial availability of small digital video cameras and digital video editing software, data was collected to evaluate the use of these systems in marine monitoring studies. Biotope richness (ie. The number of biotopes present, rather than species diversity within a biotope), was assessed from the recorded video.

Towed sled video-based monitoring method, as described in Connor et al. (1997). Biotopes described in Connor et al., (1997) were identified following reviews of recorded video. In 2010 a subset of videos were re-analysed to provide further habitat and species detail.
