00:00:00.000 --> 00:00:03.700


2
00:00:03.720 --> 00:00:08.140
The ship is unique in numerous ways from other ships that I’ve been on.

3
00:00:08.160 --> 00:00:13.380


4
00:00:13.400 --> 00:00:15.920
An ROV is a remotely operated vehicle.

5
00:00:15.940 --> 00:00:19.250
It’s tethered to the ship.

6
00:00:19.270 --> 00:00:21.780
Coming up on the ROV.

7
00:00:21.800 --> 00:00:22.860
It can move underwater.

8
00:00:22.880 --> 00:00:26.460
It has video camera capabilities, so it’s essentially a robot underwater

9
00:00:26.480 --> 00:00:29.100
that pilots control on the ship side.

10
00:00:29.120 --> 00:00:34.530
Yeah, Andrea, I’d love to get a zoom on the solitary hydroid there at some point.

11
00:00:34.550 --> 00:00:36.090
Okay.

12
00:00:36.110 --> 00:00:37.800
My name is Andrea Quattrini.

13
00:00:37.820 --> 00:00:40.100
I’m a PhD student at Temple University.

14
00:00:40.120 --> 00:00:42.850
I study deep-sea coral ecosystems.

15
00:00:42.870 --> 00:00:48.970
And out slow to full wide.

16
00:00:48.990 --> 00:00:51.000
I’m a ship-based science team lead.

17
00:00:51.020 --> 00:00:56.980
My role is to communicate and coordinate with scientists on shore as well as the ROV

18
00:00:57.000 --> 00:01:02.050
team to make sure that ROV operations go smoothly and science objectives are met.

19
00:01:02.070 --> 00:01:06.040
I’d also like to know, where is this rock coming from?

20
00:01:06.060 --> 00:01:11.700
Um, I know we’re down to 1,800 meters or so…tell me it rolled downhill.

21
00:01:11.720 --> 00:01:14.770
But I’m really wondering what this rock is made of.

22
00:01:14.790 --> 00:01:16.590
Are we looking at continental-type crust here?

23
00:01:16.610 --> 00:01:19.610
Are we looking at something else?

24
00:01:19.630 --> 00:01:23.470
The telepresence component here is definitely a unique experience.

25
00:01:23.490 --> 00:01:27.240
Scientists back on shore are listening in and communicating with us

26
00:01:27.260 --> 00:01:33.020
in real time as the ROV is exploring the bottom of the seafloor.

27
00:01:33.040 --> 00:01:36.490
Also, it allows the public and the viewers to see in real time what

28
00:01:36.510 --> 00:01:39.690
we’re observing and to explore the dive with us.

29
00:01:39.710 --> 00:01:43.130
We are currently at a depth of 1,875 meters.

30
00:01:43.150 --> 00:01:48.300
Here in the control van, this is where all the action happens.

31
00:01:48.320 --> 00:01:52.220
For any new listeners joining us, we are off of the

32
00:01:52.240 --> 00:01:57.200
northeast U.S. coast in the canyons system.

33
00:01:57.220 --> 00:02:00.020
We are on the lower continental slope.

34
00:02:00.040 --> 00:02:04.730
We’re off the coast, in waters off of New Jersey and Rhode Island.

35
00:02:04.750 --> 00:02:10.360
The ROV pilots are manipulating and maneuvering the ROV and the scientists sit

36
00:02:10.380 --> 00:02:16.080
in the back and help plan and lead ROV dives from the science perspective.

37
00:02:16.100 --> 00:02:19.190
So we have about an hour left in the dive, so we’ll start moving back

38
00:02:19.210 --> 00:02:22.670
up slope and then heading toward the top of the feature.

39
00:02:22.690 --> 00:02:26.340
We really hope to characterize and discover new habitats, including deep-sea coral

40
00:02:26.360 --> 00:02:31.410
communities, potential cold-seep habitats or chemosynthetic communities.

41
00:02:31.430 --> 00:02:35.970
And we also are exploring geological features pertaining to

42
00:02:35.990 --> 00:02:39.790
landslide areas along the continental slope.

43
00:02:39.810 --> 00:02:42.430
Even though this may have been in place quite a while ago,

44
00:02:42.450 --> 00:02:52.230
there’s still active processes going on even at the smaller boulder scale.

45
00:02:52.250 --> 00:02:55.640
We’re going to hopefully see several deepwater coral communities.

46
00:02:55.660 --> 00:02:59.180
Deepwater corals are, many of them are long lived and slow growing

47
00:02:59.200 --> 00:03:04.000
and thus they’re susceptible or vulnerable to anthropogenic disturbances.

48
00:03:04.020 --> 00:03:06.910
We also could see chemosynthetic communities,

49
00:03:06.930 --> 00:03:10.670
and these communities are found in cold seep areas.

50
00:03:10.690 --> 00:03:15.590
They house unique and different communities from other areas of the deep seafloor.

51
00:03:15.610 --> 00:03:21.890
Both of these are types of biological hot spots, so you get high biodiversity of animals

52
00:03:21.910 --> 00:03:28.510
in these areas compared to other fauna that you see on the surrounding seafloor.

53
00:03:28.530 --> 00:03:30.250
ROV in sight.

54
00:03:30.270 --> 00:03:31.620
No thrust on.

55
00:03:31.640 --> 00:03:32.810
Copy that.

56
00:03:32.830 --> 00:03:36.660
Yeah, we can go ahead and bring Seirios aboard.

57
00:03:36.680 --> 00:03:38.830
Pilot, dive super.

58
00:03:38.850 --> 00:03:39.750
Go ahead dive super.

59
00:03:39.770 --> 00:03:41.650
Yeah, we can secure power.

60
00:03:41.670 --> 00:03:42.710
Copy that.

61
00:03:42.730 --> 00:03:44.360
High voltage is off.

62
00:03:44.380 --> 00:03:53.020


63
00:03:53.040 --> 00:03:56.980
