00:00:00.000 --> 00:00:04.020


2
00:00:04.040 --> 00:00:08.850
We are currently in an inter-canyon area, between Veatch and XX Canyons

3
00:00:08.870 --> 00:00:13.200
and we are headed to a target depth of about 1,468 meters.

4
00:00:13.220 --> 00:00:20.990
We detected water column anomalies or active gas coming out of the seafloor

5
00:00:21.010 --> 00:00:26.330
in the water column data collected from multibeam mapping.

6
00:00:26.350 --> 00:00:30.600
And so we are going to the site to ground truth these plumes

7
00:00:30.620 --> 00:00:36.900
and hopefully find chemosynthetic communities.

8
00:00:36.920 --> 00:00:39.540
Right here we’re coming up on a huge patch of mussels.

9
00:00:39.560 --> 00:00:46.640
This is going to be one of the biggest patches of mussels that we’ve seen so far.

10
00:00:46.660 --> 00:00:53.830
We’re almost right there on top of what we had as a seep target based upon the multibeam

11
00:00:53.850 --> 00:01:00.250
mapping that was done last night.

12
00:01:00.270 --> 00:01:02.420
We are off the northeastern U.S. coast,

13
00:01:02.440 --> 00:01:04.600
surveying the continental slope in an area

14
00:01:04.620 --> 00:01:07.750
known as the U.S. canyons region.

15
00:01:07.770 --> 00:01:12.170
We’ve found a large mussel bed community and this is the

16
00:01:12.190 --> 00:01:16.270
first time we’re viewing this area so far in the deep sea.

17
00:01:16.290 --> 00:01:24.330


18
00:01:24.350 --> 00:01:27.650
We’re getting a zoom in on where we are and you can see

19
00:01:27.670 --> 00:01:33.600
tons of bubbles coming off underneath that ledge.

20
00:01:33.620 --> 00:01:37.410
Excellent.

21
00:01:37.430 --> 00:01:43.970
There is hydrate under there, see that little snow cone underneath of there, that ledge.

22
00:01:43.990 --> 00:01:46.480
So this is great video, this is really nice.

23
00:01:46.500 --> 00:01:52.680
I think this is, see, … I think this is an icy coating, I think this is hydrate.

24
00:01:52.700 --> 00:01:54.170
See that bubble right there?

25
00:01:54.190 --> 00:01:56.530
This is awesome.

26
00:01:56.550 --> 00:01:59.270
I agree with you Carol, this looks a lot icier than…

27
00:01:59.290 --> 00:02:01.890
Oh, that is awesome!

28
00:02:01.910 --> 00:02:05.960
Oh my gosh, this white stuff in the water column, now this could be very significant,

29
00:02:05.980 --> 00:02:08.700
this may actually be hydrates forming in the water column.

30
00:02:08.720 --> 00:02:10.510
You see these white flecks coming up?

31
00:02:10.530 --> 00:02:11.410
Yeah.

32
00:02:11.430 --> 00:02:13.070
Yeah.

33
00:02:13.090 --> 00:02:14.440
That’s very …

34
00:02:14.460 --> 00:02:21.220
And it’s very possible that we’re forming hydrate in the water column as it comes up.

35
00:02:21.240 --> 00:02:33.210


36
00:02:33.230 --> 00:02:39.490
This is about within eight meters of where we had the target

37
00:02:39.510 --> 00:02:47.000
identified based upon the multibeam mapping.

38
00:02:47.020 --> 00:02:56.970
And we’re at a depth of 418 meters and we are viewing active venting from the seafloor.

39
00:02:56.990 --> 00:03:13.920


40
00:03:13.940 --> 00:03:19.240
There’s a great view of some of the bubbles coming up on the Seirios view.

41
00:03:19.260 --> 00:03:23.420
It looks like this is going to conclude our dive today, the 12th of July.

42
00:03:23.440 --> 00:03:25.810
The time is 1538.

43
00:03:25.830 --> 00:03:28.960
Our bottom depth is 1,413 meters.

44
00:03:28.980 --> 00:03:32.360
We’ve been along the continental slope of the northeastern U.S.

45
00:03:32.380 --> 00:03:38.790
coast and we targeted a few different sites that we mapped last night

46
00:03:38.810 --> 00:03:41.790
and confirmed water column anomalies.

47
00:03:41.810 --> 00:03:49.390
We landed down and we came across patches of mussels and a fairly large mussel bed.

48
00:03:49.410 --> 00:03:56.120
One of the bigger ones, well, the biggest mussel bed that we’ve seen leg anyways.

49
00:03:56.140 --> 00:04:17.980
