The project develops local capacity to undertake comprehensive marine resource assessments of Anguilla’s ‘Blue-Belt’, delivering best practice guidance for combining satellite and acoustic surveys, to extend mapping into deeper waters for the first time.

The groundtruthing survey ran for 10 days in September 2016 following the MBES survey, The frame collected both high definition video and stills of the seabed in carefully selected locations around Anguilla. Using the acoustic data and local stakeholder engagement, stations were positioned around Anguilla to best describe the different habitats and substrates present. The camera system consisted of a Bowtech Video Camera and two GoPro cameras attached to a custom-made frame. At each station the vessel was positioned to the upstream side of the location and the camera was lowered to just above the seabed. The vessel was then allowed to drift over the position while the cameras collected high definition video and stills data. Each camera station lasted for 10 minutes before the camera was recovered and the vessel moved on to the next station. The still and video data were assessed for benthic habitat composition. Benthic habitat composition per photograph was assessed in terms of percentage cover using Coral Point Count® (v4.1); a software tool for determining community statistics of benthic photographs. Percentage cover was derived by randomly assigning 24 points over each photograph and then identifying the species or substrate at each point. Benthic habitat types were selected based upon the classifications derived by Mumby and Harborne (1999)[1] with adaptations for Anguilla’s management purposes and habitats specific to Anguilla.
