General Note:
Dive 4849 - Deploy eye-in-the-sea. Exchange traps. Collect fluorescent specimens.
Monitored the jellyfish on the eye-in-the-sea during the descent. Moved from flat silty bottom to group of rocks to search for the pinger to exchange traps and site of deployment of eye-in-the-sea. Eye-in-the-sea deployed at 16:50 at a depth of 1825 ft. Traps were exchanged from 17:10 to 17:33. Most crabs were too large to fit through the trap opening, but one still defended the opening from a large hagfish. **Switched to blue lights. Moved the arc light so that it pointed aft. Searched rocks in immediate area near pinger location. Filmed a green fluorescent shark on bottom not near any rocks. Swam away before could attempt collection. On rock found zooanthid with bright green fluorescent polyps. Collected two specimens in buckets 1 and 2. Moved over sandy bottom and collected a cup coral in bucket 3. Continued to a nearby rock grouping and collected a rock with orange fluorescent sponge in bucket 4. Over sandy bottom again collected a wire coral showing some possible reddish fluorescence in bucket 5. On small grouping of rocks found green fluorescent batfish which was collected in bucket 6. All organisms found with blue light, then collected with the aid of regular lighting.
Abstract:
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.
