<jats:title>Summary</jats:title><jats:p> <jats:list> <jats:list-item><jats:p>Managing ecological systems, which operate over large spatial scales, is inherently difficult and often requires sourcing data from different countries and organizations. The assumption might be made that data collected using similar methodologies are comparable, but this is rarely tested. Here, benthic video data recorded using different towed underwater video systems (<jats:styled-content style="fixed-case">TUVS</jats:styled-content>s) were experimentally compared.</jats:p></jats:list-item> <jats:list-item><jats:p>Three technically different <jats:styled-content style="fixed-case">TUVS</jats:styled-content>s were compared on different seabed types (rocky, mixed ground and sandy) in Kingmere Marine Conservation Zone, off the south coast of England. For each <jats:styled-content style="fixed-case">TUVS</jats:styled-content>, species metrics (forward facing camera), seabed impact (backward facing camera) and operational performance (strengths and limitations of equipment and video footage) were compared with the aim of providing recommendations on their future use and comparability of data between different systems.</jats:p></jats:list-item> <jats:list-item><jats:p>Statistically significant differences between species richness, density, cover and assemblage composition were detected amongst devices and were believed to be mostly due to their optical specifications. As a result of their high image definition and large field of vision both the benthic contacting heavy and benthic tending <jats:styled-content style="fixed-case">TUVS</jats:styled-content> provided good quality footage and ecological measurements. However, the heaviest <jats:styled-content style="fixed-case">TUVS</jats:styled-content> proved difficult to operate on irregular ground and was found to cause the most impact to the seabed. The lightest <jats:styled-content style="fixed-case">TUVS</jats:styled-content> (benthic contacting light) struggled to maintain contact with the seabed. The benthic tending <jats:styled-content style="fixed-case">TUVS</jats:styled-content> was able to fly over variable seabed relief and was comparably the least destructive.</jats:p></jats:list-item> <jats:list-item><jats:p>Results from this study highlight that particular care should be given to sled and optic specifications when developing a medium‐ or long‐term marine protected area monitoring programme. Furthermore, when using data gathered from multiple sources to test ecological questions, different equipment specifications may confound observed ecological differences.</jats:p></jats:list-item> <jats:list-item><jats:p>A benthic tending <jats:styled-content style="fixed-case">TUVS</jats:styled-content> is recommended for benthic surveys over variable habitat types, particularly in sensitive areas, such as marine protected areas.</jats:p></jats:list-item> </jats:list> </jats:p> | |
