This was a blue water dive. This involves diving on a tether system. There is a main drop line of 100 feet. A ring is attached to this and four tethers are attached to the ring (which is called a trapeze). One person works as a safety diver, keeping the lines untangled and looking for sharks. The rest have different roles. Justin Marshall and I did filming with a special camera. This camera flips back and forth between two polarization states, so that we can see what animals with polarization vision may be able to see. The camera can also be fitted with a filter that only lets through UV light, so we can see what animals with UV vision can see. Actually getting good footage involves first catching some animals and then transferring them to a filming tank underwater. This keeps them in place. We then film them in the different ways described above.**In addition we are measuring the polarization levels underwater and collecting animals for shipboard imaging and behavioral experiments
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.
