    "description": "Survey run by Seastar Survey for Dorset Wildlife Trust. Ground-truthing survey to identify important seabed habitats off Dorset. Survey transects were selected using multibeam bathymetry and backscatter survey results. 119 survey lines, either 500m or 1000m long, were surveyed using a number of video and still cameras attached to a frame lowered to the seabed. A live feed from the video camera to the survey vessel allowed continuous monitoring of the camera frame. High resolution video was continuously recorded from the seabed cameras and still photographs were taken using a surface controlled trigger. Survey vessel position was recorded by GPS, depth recorded by vessel echosounder.\r\n Semi-quantitative analysis of the video footage and quantitative analysis of the still photographs was carried out following the survey.",
