NPR/NGS RADIO EXPEDITIONS Show: Earle / Deepworker Log of DAT #: 3 Date: Jan 1999 ng = not good ok = okay g = good vg = very good Lecture from to 58:00 00:58:07 On shore at MBARI (Monterey Bay Aquarium Research Institute), fog horn in back, talking with Bruce Robison. 00:58:48 AC: We¿re probably 200 ft. from the ocean. 00:59:05 BR: I¿m Bruce Robison, I¿m a senior Scientist here at MBARI AC asks about utility of subs. -- what do you think when you see Deepworker (DW)? 00:59:26 BR: It rep. A new opp. To get into the habitat that I work in ¿ the deep parts of the ocean with a great deal of freedom and mobility to make observations and measurements and conduct experimental work. DW is a rev. technique in terms of putting scientists in to the sea with the mobility to conduct research. 00:59:58 AC: as a scientist what¿s going to be different for you in this kind of device as opp. To previous generations¿deep rover? 01:00:12 BR: The advantages that DW offers over Deep Rover as a biologist is that DW is smaller, which means its less obtrusive, much more maneuverable, and its faster so that I can enter the habitat create far less disturbance than I would with a larger vehicle and uh I can move around more easily both in terms of speed and flexibility than was w the case with Deep Rover, although DR was a terrific tool for the jobs we applied it to, this is just a significant improvement in all of these areas. 01:00:52 AC: At what depths do you work, do you like to work? 01:00:55 BR: As deep as I can get - the animals that I work on range from about 200 meters below the surface down to about 3000 meters below the surface so we¿re only biting off a so we¿re only biting off a relatively small chunk of the habitat with DW and deep rover there¿s still lots more to explore. 1:01:25 AC: and what is the use for you in being able to go down there in a sub rather than use one of these ROVs that you¿ve been talking about. 1:01:36 BR: well there are different things that each type of system does best and really its not an either/or issue but the kind of things that human occupied vehicles do better is to make larger scale obs. With an ROV using a video camera as your observation tool you lack the depth of field and overlap of visual fields that lets you see things with a three dimensional relationship also using a video camera on an ROV is a bit like looking through a pipe with one eye. You see a relatively small volume of water and as a consequence you lose the big picture using a human occupied vehicle on a much larger scale you see a much greater volume of water and thus for a biologist you can understand a great deal more about how animals interact how they orient themselves with each other how close they are how far apart they are and you can see all of that at much lower levels of light bc human eyes sup to cam systems¿and uh overall get a much better feel for what things are actually like when its your own eyes attached to the portable computer between your ears that¿s doing the observing 1:03:10 AC: when you set out in DW on a research trip, do you know what you¿re looking for? 01:03:17 yes and no we have in mind the things that we hope to measure and report but always we keep o...
