ct "4:06 in afternoon, working way toward back and a bit of?" hear only on right, sound fills out at about :40

postscript

1:24 tb "so we're here at the end of the day, the ROV went down twice for about 2 or 3 hours what do we learn from those dives"

1:33 pa "well this is a unique opportunity in that we were able to revisit a site that we had seen about eleven years ago ... we were talking before about the fact that there are very few areas in deep waters where there's been any sort of continuous monitoring of the effects of human activities both in terms of the effects of natural disturbances and the effects of human activities on sea floor habitats and the animals that live there actually 1was pleasantly surprised that there wasn't really that much change based on what we saw in 1986."

2:25 tb "start again, chuck?"

2:59 tb "After a couple of dives with phantom s-2 what do we learn today?"

3:00 pa restates above ... we didn't see any evidence of mobile gear fishing 3:50ish

4:38 tb "but the fact that you didn't see any evidence in heavily trawled"

pa "no it hasn't been really trawled at all .. "

tb "oh"

4:57 pa "This area has been traditionally fished with gill nets ... "

5:41 tb "twenty five years on, how valuable are these nms and how should they be improved upon?"

5:50 pa "I think the nms programs is an outstanding example of system that provides special protection for areas of the ocean and there are certainly lots of questions for the usefulness of going out on the sea and drawing lines around it. "

6:10 pa "The nms program are designed to have multiple uses diff types of protection for diff areas within and between sanctuaries."


6:30 pa "Stellwagen is a multiple use sanctuary in that all existing uses were grandfathered into the designation of the site and I think: we need to have a range of sites or a number of sites with a range of uses ... "

7:00 pa "in order to move toward some sort of sustainability we need to have some kind of system and the nms program provides that template where we have area where we don't do anything in order to act not only simply from the moral imperative ... to act as barometers for what we're doing ... "

7:46 pa "Normally the ocean has been open access"

8: 16 pa "we need to move towards a plan of representative habitats ... "

8:40 tb "good, thanks"

8:50 ambi.

9:15 water, waves, motor in bg, wash by water on the Able Jay forward starboard side.

10:25 ct "stopdown ... great ending"

11:21 ct "4:25 in compartment of Able Jay with les watching video tape"

11:54 lw "this tape has three things on it, pre and post trawling from jeffrey' s bank and then a sequence from Franklin basin at a depth of180 meters and then it has some images from a camera on a shrimp trawl from northern Australia"

12:40 lw "start with gulf of Maine this is on Jeff. Bank ... glacial marine deposits ... "
(describing what's on video ... )

14:38 lw "This is what we'd expect a bottom to look like that was pretty well undisturbed you have a large number of biotic structures sticking up into the water. And you can see that in some of these areas the covering of sponges can be very very dense"

17:30 lw "That's really the issue sorting out the natural long-term variability from something that's anthropogenic but what struck us here is this is an area where we had seen large sponges before, this is a subtle effect"

19:00 lw "sponge number is started to decrease, that could be natural patchiness but right here is the door plow mark you can just see it there and there's a line running across there its like line its like a trough that's been dug in the sediment and once you get in past the door mark then you're in the area where the sweep of the trawl has impacted ...and the most noticeable thing in this sequence is that the sponges are missing ... now there are still anemones which is not a real surprise ... so this is a good example of a trawl effect which might not be so noticeable at first but after you've looked at some tapes ... "

20:40 lw "this is a camera mounted in a shrimp trawl .. "

tb "its kicking up plumes of dirt ... "

24:38 end of discussion
