2016 - 2016 Centre for Environment, Fisheries & Aquaculture Science (Cefas) Videos and still images of the seabed from the 2016 survey of Grand Anse Bay to St George's in Grenada
As part of the Commonwealth Marine Economies Programme (CMEP) Cefas collected 50 drop camera video tows of the seabed off the coast of Grand Anse Bay to St George's, in Grenada, to characterise the benthic fauna within the area and support the creation of benthic habitat maps. The videos and still images were acquired during the 2016 survey using a lightweight drop camera frame with a SubC camera, two lasers for scaling images and additional lighting for real colour images of the seabed. The drop camera frame was lowered to the seabed by hand from a vessel, with the video monitored to maintain a consistent height above the seabed. Tows were 15 minutes long with the vessel drifting in neutral so the distance covered in each tow varied. Sample depths ranged from 5-60 m and covered a range of habitats including bare sediment, seagrass, and coral and sponge dominated reefs. Still images were acquired every minute at a point when the seabed was clearly in focus.

This data holding contains the raw drop camera videos and still images for all the stations collected during this 2016 survey. Standard definition video were overlaid with station information, GPS and time, and high-definition video contain no overlaid metadata. Still images also contain no overlaid metadata as the GPS positions and extracted information are stored in the Proforma document.
