Time | Heading | Depth | Comments |
0917 | x 455 y -423. We see bottom. Folded sheet lava and flat striated sheet lava. (helluhraun). Heavily sedimented at least 2.5. Settling down to take sample 1. | ||
0921 | Sitting on heavily folded sheet flow. With thick sediment cover - not much glass seen. | ||
0931 | Just finished picking up rock sample number 1 into basket location 7a. Folded sheet: glassy.. | ||
0933 | 2610 | Going from folded sheet to flat sheet. Heavily sedimented: 100% cover on the flat sheets. Step caused by subsided flat sheet flow. Up step and into lobate flow with similar heavy sediment cover as before: scale 2.5 - 3. | |
0935 | 114 | 2610 | Over lobate lava. Similar sediment thickness. See glass but not glassy. |
0936 | 114 | 2608 | Over lobate lava then on to folded sheets again grade into jumbled flow. A drop/step looks like collapse. First a small one and then a bigger one. Collapse with a broken sheet flow at the bottom. |
0939 | 111 | 2606 | Passed a contact in the lava: could be in a younger flow. |
0940 | 2609 | Broken up and folded sheet flow: still heavily sedimented where there are flat surfaces. Coming up to another collapse. Broken sheet flow. | |
0941 | 113 | 2611 | Another drop: Blee suggests a fault from orientation. Jumbled sheet flow. Seems to be glassier with less sediment but difficult to judge because of the jumbled sheet flow. |
0943 | 113 | 2608 | Over jumbled sheet flow. Looks more glassy. Heavily folded and jumbled sheet flow. 150 meters from waypoint 2. |
0945 | Coming up to lobate with folded sheets. On the margin of lobate and folded sheets. This could be the contact. With significantly less sedimentation than in the beginning. May be down to 1.5. | ||
0947 | 110 | 2605 | Over lobate flow into jumbled sheet flow with very uneven topography. |
0948 | From jumbled sheet and into lobate. Definitely more glass than in the beginning. Occasional pillows in lobate flow. | ||
0949 | 101 | 2602 | Over lobate. Large wavelength lobate with a lot of buds. Into short section of pillows and then back into lobate flow. |
0951 | 101 | 2600 | Close to bottom over lobate flow. Fair amount of sediment: 1.5. |
0953 | 101 | 2601 | Close to bottom on lobate flow. Sediment about 1.5. |
0954 | 101 | 2598 | Moving from lobate to lobate with pillows. Mainly lobate. |
0955 | 102 | 2597 | Travelling over lobate flow. Fair amount of sediment on flat surfaces. |
0957 | 101 | 2596 | Over lobate flow. A small but deep collapse 5-6 m diameter. Into pillow/lobate: much more broken up than before. Channels? With lobate and folded sheets. Many small collapses. |
0958 | 103 | 2593 | Over lobate with lot of buds. Sediment could be less than before. Still over lobate with lot of buds. |
1000 | Coming over lobate with sheets. | ||
1005 | 2590 | Collecting sample 2: x 843 y -534 | |
1009 | 2590 | x 839 y -533 | |
1012 | 113 | 2587 | Over lobate lava. Less sediment than in the beginning. Increasing biological activity. Pillows with buds in a lobate flow. |
1013 | 115 | 2585 | Over lobate flow with occasional pillows. Definitely less sediment than in the beginning. |
1014 | Lobate flow with occasional pillows. | ||
1017 | 2581 | x 925 y -576. Have arrived in Oasis. Yellow fiber optics cable over a collapse. | |
Temperature 5.17 C and 4.9 C. Mussel collecting. | |||
1034 | 2582 | x 932 y -582 Mussel pot sampling. | |
1058 | Moving about Oasis. Deep collapses. In a collapse area. | ||
1059 | 2581 | x- 941 y- -589. Over collapses. The flow appears to be lobate. | |
A dead extinct chimney 13 meters high. | |||
1103 | 214 | 2580 | Just passed over a collapse area. Lobate flows on top. |
1104 | 060 | 2581 | Many collapses in lobate flows. Over a collapse still with some of the roof rock standing. |
1105 | 2582 | Over a big collapse. | |
1114 | 2581 | x- 939 y- -592 On the edge of a collapse. Sampling mussels. | |
1120 | Mussel pot 2 in the basket. | ||
1134 | Moving between biosample localities and are again on the edge of a deep collapse. | ||
1137 | 2582 | x 939 y -579. Settling down to take biosample number 3. | |
1159 | 2582 | Just picked up sample pot. x 938 y -579. Simmering among the mussel groups and white coloring of the mussels where there is maximum simmering. | |
1214 | Sampling near a collapse with fine scale layering in the walls, each cm to few tens of cm maximum and with lava pillars. | ||
1216 | 002 | 2581 | More collapses. In a collapse area. |
1243 | 2582 | x- 944 y- -531 Just collected a biological sample. | |
1309 | 2582 | Collecting mussels. | |
1321 | 325 | 2582 | Moving slowly over collapses and folded sheets. |
1329 | Measuring temperature 5.9 C | ||
1337 | 2583 | Just picked up sample number 3 with barnacles | |
1353 | Lava beginning to look more glassy and less sedimented than on the first part of the drive from Oasis. Might have crossed a contact. Lobate lava with pillows. | ||
1356 | Collecting a rock sample. | ||
1400 | Collecting Took video of the less lobate lava we are collecting. | ||
A gap in tape | |||
1504 | 2583 | x 1571 y 553. Over lobate lava with pillows and lots of buds. | |
1505 | Over lobate lava with lot of buds. Sediment thickness 0.5:1. See lot of glassy surfaces. | ||
1514 | Black smoker. x 1627 y -540. Leaving for the surface. |
