Dive 4852 - Deploy EITS, deploy 2 crab traps and bait bag with pinger, collect galatheid crabs under orange light
Dive started at base of knoll on muddy bottom. Urchins and an isopod (Bathynomus) were present. We worked our way up and over the knoll, turning around to return to the top of the knoll. Lophelia coral and orange gorgonians were abundant at the top, with galatheid crabs in the coral rubble. A long, straight, deep groove (~10ft) ran along the knoll (maybe cut by a cable?). Hake and rockfish were seen. Many pelagic crustaceans were present near the bottom (amphipods, sergestids, euphausids).
To look into the ocean with new eyes, in order to provide a comprehensive characterization of the deep-sea benthic environment.Objectives:1. Continue unobtrusive observations with the Eye-in-the-Sea Camera2. Continue studies of ecological roles of fluorescence in marine organisms.3. Quantify the deep-sea environment as it is perceived by its inhabitants.4. Determine the role of polarized light receiption in the pelagic environment.5. Determine the extent of polarized light reception in deep-sea organisms.6. Determine adaptations in deep-sea benthic organisms for increased sensitivity to light.
