21 | 57 | 1522 | 148 | 423704 | 5086772 | Give a man enough ROPOS . | R496-18 |
21 | 56 | 1522 | 144 | 423701 | 5086775 | During the past half hour have managed, with difficulty, to get the large yellow cable around the leg of the rumbleometer. | |
21 | 57 | 1522 | 150 | 423617 | 5086954 | ….and he'll probably hang himself | R496-19 |

22 | 6 | 1511 | 310 | 424494 | 5086982 | Returning to cage unreeling gray line. | |
22 | 7 | 1502 | 220 | 423694 | 5086786 | ROPOS is in its cage. | |
22 | 24 | 1451 | 231 | 424331 | 5087472 | OK a little brinkmanship | R496-23 |
22 | 23 | 1451 | 239 | 423724 | 5086754 | Continue to raise cage in order to get gray line out to double red tape marks. Line accidentally in the cutter but got out OK. | |
22 | 34 | 1451 | 311 | 423717 | 5086767 | hooked to the bottom of the cage | R496-24 |
22 | 34 | 1451 | 314 | 423667 | 5086915 | Cage end of line drooped attempting to snap hook to bridle. | |
22 | 48 | 1451 | 360 | 423722 | 5086766 | OK this time for sure | R496-25 |
22 | 49 | 1451 | 5 | 423722 | 5086767 | Snap hook recovered with difficulty and attached to ring on bridle. | |
22 | 50 | 1452 | 6 | 424269 | 5087996 | Keith S. asks to move the ship 20 meters at 10 degrees | |
22 | 55 | 1451 | 320 | 423728 | 5086765 | waiting for the ship to move | |
22 | 58 | 1448 | 270 | 423668 | 5086704 | reeling in cage at 4 meters/min | |
23 | 4 | 1435 | 336 | 424482 | 5088083 | Hook came of off where it was hooked to the cage. | |
23 | 6 | 1435 | 348 | 423703 | 5087207 | The hook with a safety clip was somehow twisted, causing the catch to open, and the hook fell off. Now, we have to go back to the seafloor, try to pick up the hook on the end of the line and re-attach it to the chain beneath the cage. Cage now descending. | |
23 | 10 | Visible particle plume while cage descends, at 1470 m | |||||
23 | 14 | 1492 | 358 | 423734 | 5086750 | Near the bottom, ROPOS ready to come out of cage, when we saw the spectra line floating up in the water. The line is buoyant, so one end is on the rumbleometer, and the other is on the hook on the seafloor, with a loop floating up in the water column. | |
23 | 18 | 1492 | 272 | 423492 | 5087295 | A-l ROPOS telemetry has died. Network down. | |
23 | 21 | 1492 | 272 | 423386 | 5087692 | asked the ship to move 40 meters west | |
23 | 43 | 1401 | 22 | 423703 | 5086779 | Still attempting to get vehicle telemetry back up. Vehicle is in cage, and line is not attached. | |
23 | 46 | 1401 | 63 | 423708 | 5086797 | Bill is working the cube. The telemetry is back up. Could there be a connection? | |
23 | 55 | 1478 | 127 | 423451 | 5087613 | Saw the spectra line again. | |
23 | 56 | 1472 | 115 | 424308 | 5088104 | Asking the ship to move 20 meters West. Stern of ship is currently about 10 meters W of rumbleometer. | |
23 | 58 | 1473 | 284 | 421212 | 5086968 | Situation: Hook was dropped 30 meters brng 010 from the rumbleometer, with line floating in between. Plan :Come down W of instrument, drive up to it, grab line loosely in the claw and drive up, letting the line slip until the hook is within reach. | |
0 | 5 | 1517 | 121 | 423710 | 5086686 | We are back on the seafloor, looking for the rumbleometer. | R496-26 |

0 | 34 | 1429 | 126 | 423705 | 5086764 | It was an unusual jellyfish that we were looking at from one end and couldn't identify it at first. It was black in color. | |

0 | 45 | 1431 | 135 | 423608 | 5086909 | Drooped the hook. Puled out of the arm by a big surge. | |
0 | 48 | 1430 | 33 | 423642 | 5087482 | Moving the ship 64 meters. Will try to retrieve the hook. | |

1 | 7 | 1490 | 300 | 423697 | 5087462 | ROPOS is out of the cage for hook recovery, take 3. | |
1 | 9 | 1519 | 354 | 423731 | 5086758 | We have a good fix on ROPOS. | |
1 | 11 | 1521 | 248 | 423732 | 5086746 | Rumble-o-meter back in sight. | |
1 | 12 | 1519 | 298 | 424492 | 5088003 | Line in the claw one more time. | |

1 | 22 | 1428 | 304 | 423744 | 5086709 | At the end of the line. Preparing to grab the hook. | |
1 | 25 | 1434 | 299 | 423685 | 5086923 | Both claws on the hook once again. | |
1 | 26 | 1432 | 304 | 423716 | 5086752 | Hand of off hook. | |
1 | 33 | 1440 | 326 | 423725 | 5086762 | Ropos back in cage. | |
1 | 58 | 1406 | 244 | 423747 | 5086756 | Hook re-attached to cage, pulled with the winch, tension went up, then slack, then lifting bridle released from cage. Now we are going down to look at the rumbleometer. | |
2 | 0 | 1406 | 242 | 424139 | 5086273 | Moving the stern of the ship to about 25 m west of the rumbleometer. | |
2 | 20 | 1406 | 168 | 423679 | 5086757 | P-code of, so ship position not stable enough to go out of cage. Waiting to se if P-code comes back on. | |
2 | 45 | 1406 | 282 | 423688 | 5086754 | P-code is back, so we can venture out of the cage. | |
3 | 6 | 1522 | 125 | 423627 | 5087288 | Rumble base. Where is the rest? Stay tuned. | R496-33 |
3 | 4 | 1517 | 129 | 423687 | 5086768 | On the bottom. Collapse area, pillars. Found the weight, lost the handle. The Rumbleometer is FREE! The weight doesn't show much effect of the flow on it. Mostly it is sitting on top of the flow. Back edge appears to be overlain by the flow. | |
3 | 9 | 1516 | 140 | 423622 | 5087270 | Rubble on top of weight may have been from breaking it away from the lava. Found the line that now holds the Rumbleometer. | |
3 | 12 | 1481 | 113 | 424468 | 5086951 | Going up the rumbleometer line. it is hanging in the water sideways. | |
3 | 14 | 1466 | 210 | 424216 | 5088122 | Yes! Rumbleometer floating in water column from anchor. | R496-34 |
3 | 17 | 1470 | 138 | 423714 | 5086741 | Survey of it to see what lines are where. Too late to cut it, because of darkness approaching. Will try to release it tomorrow AM. | |
4 | 25 | 1518 | 96 | 423780 | 5087057 | On the bottom, in lobate flows that look fairly young. Close to Mkr-33. | |
4 | 27 | 1519 | 71 | 423802 | 5087066 | Collapse area in lobates. Flat sheets now with staining on fractures. | |
4 | 29 | 1520 | 117 | 425114 | 5087076 | At Mkr-33. Going to pick up BioBox. | |
4 | 39 | 1525 | 272 | 423854 | 5087040 | picking up BioBox that is located near the elevator debris. | |
4 | 45 | 1525 | 274 | 424398 | 5087491 | Picked up box, tried Wallace maneuver now heading to mkr-113. Will be doing an Imagenex line during transit. | |
4 | 48 | 1525 | 274 | 423865 | 5087082 | Testing Imagenex to see if it will work with BioBox in the arm. Resting BioBox on frame. | |
4 | 59 | 1504 | 255 | 424373 | 5087504 | Moving ship to north end of Imagenex line W1 from Mkr-33 site. We will do this line south, then go over to Mkr-113 to collect a bio sample, and then will resume the Imagenex survey. | |
5 | 20 | 1496 | 348 | 423710 | 5087682 | We're actually going to be starting Imagenex line W2 from the north instead of W1. We'll do W1 later. | |
6 | 23 | 1499 | 182 | 423554 | 5086727 | At 05:37 we started at the north end of Imagenex line W2, southbound. | |
7 | 15 | 1499 | 217 | 423555 | 5085892 | End Imagenex line W2 (south end). Ship will now go over to Mkr-113 to collect a bio sample into the portable bio box. | |
7 | 42 | 1521 | 21 | 423326 | 5085385 | ROPOS on the bottom near Mkr-113 (not there yet) | |
7 | 46 | 1522 | 86 | 423356 | 5085936 | We've spotted the Mkr-113. | |
7 | 47 | 1524 | 154 | 422686 | 5084942 | ROPOS on the bottom at Mkr-113. | |
7 | 49 | 1524 | 154 | 423380 | 5085929 | Placing the portable BioBox near Mkr-113 in order to put samples in it. | |
7 | 50 | 1524 | 156 | 423362 | 5085932 | One of the corks in the BioBox is rolling around in the bottom of the BioBox, we think. | |
7 | 52 | 1524 | 153 | 423371 | 5085939 | we can see a group of new tube worms right in front of us, as well as Craig's bacterial traps. | |
7 | 53 | 1524 | 146 | 423369 | 5085937 | We're trying to open the portable BioBox now | |
7 | 54 | 1524 | 145 | 423411 | 5086201 | We have opened the BioBox. | |
7 | 54 | 1524 | 148 | 422799 | 5085391 | The cork from the center of the BioBox is indeed floating about the BioBox. | |
7 | 56 | 1522 | 152 | 423377 | 5085937 | We can se some of the blue protozoan mat, as well as a ton of limpets and maybe some snails and other gastropods. | |

8 | 3 | 1524 | 156 | 422896 | 5085766 | The limpets seem to be settled only around the black area on the bacterial traps. | |
8 | 4 | 1524 | 158 | 425309 | 5085954 | The traps are in the box. | |
8 | 5 | 1524 | 157 | 423666 | 5085590 | Heading back over to the exact same area to take a good tube worm grab. | |

8 | 11 | 1524 | 121 | 423371 | 5085934 | We are going back for more worms, but they belong to the same sample number, R496-3. | |
8 | 12 | 1521 | 340 | 423372 | 5085934 | We are approaching from the other direction this time for the tube worm grab. | |
