10 | 46 | 1522 | 272 | 423901 | 5087117 | Back at Mkr-21. Facing heading 285. Waiting for debris to clear. Range the top of the cliff = 9 meters. Adjusting the color camera to look just above the fluid sampler. | |
10 | 56 | 1523 | 282 | 423904 | 5087116 | Making sure we are getting good fixes. Currently we are stopped and sitting on the bottom. | |
11 | 6 | 1523 | 284 | 423904 | 5087118 | Starting video survey. First a lateral to the east, we are going to mow the grass, in steps of 2 meters east and west. | |
11 | 7 | 1523 | 283 | 423905 | 5087116 | Kim's tape is started. Keep a 285 heading. Begin 21:08 | |

11 | 10 | 1523 | 288 | 423904 | 5087113 | Lateral west. Past the large patch of worms. Another area of venting, big hole with tube worms. Another basin. Another vent. Now we are at the wall. Move up 2 meters. Now back North. | |
11 | 12 | 1522 | 284 | 423905 | 5087110 | Edge on South side, large drop off, coming over the pit. Photo 97 is directly over the Mkr-N4. | photo 94 - 98 |

11 | 15 | 1523 | 285 | 423902 | 5087113 | At the south edge. Turning to N to range on the pillars. New VCR tapes at 1:16. Distance to other side (pillars) is 6 meters. Back to 285 heading, stopping ahead 1 meter only. Lateral to the N, 3 meter distance from cliffs on W extremity. | |
11 | 18 | 1522 | 286 | 423905 | 5087108 | Trying camera, broken. Face of W edge, another area of venting. At the corner of W and N edge. Lost the cliff, then we nudged the pillars on the N side. Move to W and do last pass across the lower face of the clif. Still on 285. More venting. | |
11 | 21 | 1522 | 282 | 423899 | 5087123 | Moving down, now lateral to the S, passing the marker, lots of worms. | |
11 | 22 | 1522 | 278 | 423898 | 5087120 | Touching on bottom, back at the big cliffs, at edge coming up, turning N. Heading N. There is venting on a small razorback down below. Moving along the wall, past the pillar, the cliff flattens. This is a new pillar, still going N. lateralling to big wall | |
11 | 27 | 1520 | 1 | 423896 | 5087120 | Lateral to N, another bounding wall, not a continuous wall, moving S, | |
11 | 29 | 1521 | 360 | 423901 | 5087113 | Moving over Mkr-21, setting down on the bottom. Turning to 285, to map a hole that we missed earlier. | |
11 | 30 | 1522 | 282 | 423903 | 5087111 | Heading 285 from a point directly south of Mkr-21. Going out of the edge of the field. Big rock, little rock. Going back to the eastern edge of the field. | |
11 | 33 | 1522 | 290 | 423903 | 5087116 | Heading 285, going over the marker, connecting to the other marker, a short lateral to N. Redoing the same run to fill in the final gaps in coverage. | |
11 | 35 | 1522 | 287 | 423899 | 5087114 | Changed Kim's tape, we are at the eastern edge of the field. Doing a little hop (3 meter) to the south, bottom is split by a U shape. | |
11 | 37 | 1523 | 286 | 423901 | 5087112 | Starting last east to west run. over T-bone steak, straight ahead on 285, on the left is the pillar in the distance, running 250 across the last structure in the SW corner of the field. | |
11 | 40 | 1518 | 253 | 423887 | 5087110 | Small amount of venting on top and then the abyss. | |
11 | 40 | 1517 | 316 | 423885 | 5087107 | Flying along the southern edge, heading 105, break to N, other ridge (that defines the field) on the west. | |
11 | 43 | 1519 | 342 | 423891 | 5087097 | just before we went to the large structure, saw the pillar, need to go back to the pillar. Not far from marker Mkr-N4. We are now back to Mkr-21, moving S and W. | |
11 | 48 | 1520 | 234 | 423898 | 5087119 | Still looking for the pillar. | |

11 | 53 | 1488 | 338 | 424440 | 5086672 | ROPOS is back to the cage. Checking out the Nav. It is ok. Moving the ship 70 meters to the west. | |

13 | 32 | Moving probe along the crack up to back near the osmos as get closer. Return to port end of crack. Most we got around here was 10.3 Pump keeps going off. Up to 13 | |||||
13 | 37 | 1522 | 216 | 423860 | 5087100 | ROPOS is moving down the other side to look for venting from other cracks. Not much is flowing out of this other side. Moving farther away, looking for any venting. Appears to be a little venting from another crack. Setting down. | |
13 | 41 | 1522 | 108 | 423847 | 5087099 | Positioning probe in the crack. Looks like a broken up pavement. Putting probe in small crack. 3, 5, 6 deg so far. Tmax=6.5 C. Removing probe. ROPOS is moving, reprobing another area Tmax=6 | |
