The video feed was run through an overlay receiving GPS coordinates and time / date stamps from a chart plotter. Video output from the overlay was recorded direct to hard drive. The resulting drop camera system was used to survey bottom type and macrophyte cover in Port Joli, Nova Scotia. The more sheltered head of the bay consisted primarily of a sandy bottom with patchy eelgrass cover. The mouth of the bay was exposed with rocky outcrops and cobble / boulder areas covered in Irish moss and kelps. Lobsters were found scattered throughout the bay in a variety of habitats from depths of approximately 3 m to 20 m (the depth limit of the survey)"--Abstract, p. vii. |
