WEBVTT 1 00:00:02.700 --> 00:00:07.800 So what we're operating on today and what we're  targeting is a seep so some gas plumes that are 2 00:00:07.800 --> 00:00:13.380 coming out of the seafloor that were identified  during a previous expedition, EX2302, just a 3 00:00:13.380 --> 00:00:20.280 couple of months ago. Those are some healthy  looking tubeworms. Look at those. Beautiful. 4 00:00:22.320 --> 00:00:26.220 And the fact that the tubeworms are here  means that the the seeps are here. The seeps are 5 00:00:26.220 --> 00:00:30.600 definitely here. So these tubeworms do not  occur outside of chemosynthetic areas. This 6 00:00:30.600 --> 00:00:34.920 really is a needle in a haystack  situation very often. Oh oh oh oh! 7 00:00:37.800 --> 00:00:38.520 That was a wonderful shot. Thank you. 8 00:00:41.760 --> 00:00:43.800 So methane hydrate is a combination of water and gas 9 00:00:44.820 --> 00:00:50.340 Any nothing that comes out of the seafloor  has the ability to combine with water before 10 00:00:50.340 --> 00:00:55.140 it gets dissolved or before it gets carried  away and the forms this white ice-like 11 00:00:55.140 --> 00:01:00.480 material on the seafloor. These tiny bubbles gave  a glimpse of the community that might be below. 12 00:01:01.380 --> 00:01:06.900 With our sonar from the ship and then sending  down D2 2,000 meters below, seeing these small 13 00:01:06.900 --> 00:01:11.760 bubbles just always makes me reminded of like  how impressive the feat of human engineering is.
