Age 2 lobates with a few pillows out there too.
Just passed over a very small fissure, 5-10cm across, heading
280° to the sub (352° absolute).
|
1029 |
|
|
|
|
Area of small fissures on same approx. heading, ~ perpendicular
to the sub. Approaching much larger one 15 cm across. Can see
down into it ~2-3m. |

Age 2 lobates with rare pillows. Just passed over yet another
fissure. Even wider than the last one. Now we are approaching
a very large fissure, drops down 4 m or so. Can see truncated
lobates in the wall. Fissure is 5m across. |

Contact: Right after we crossed fissure
we were in new material: younger lavas. Interesting. Didn't see
exact nature of the contact, so we don't know if it is at the
edge of the fissure. Other side of fissure was definitely age
2 lobates. Now we are in age 1 lobates. Packets of sediment dusting
the surfaces. Taking Sample 3361-5. |
1034 |

Underway from sampling station 5. Going to double back to
see fissure and take a look at contact. |

Just seen contact. Definitely on east side of fissure, within
5m of fissure, by Matt's estimation (within 2m based on Alvin
video-real neat contact, check it out. Few small pillows then
lobates).
Back on original track heading.
|
1038 |
|
|
|
|
Abundant hydrothermal stainings in low-lying parts of lobates..
Sample 5 has some white staining on its interior surfaces and
we are seeing white staining along cracks on the higher standing
bits of these lobates too. |
1039 |
-1500 |
-10768 |
|
2582 |
Also seeing some localized orange staining but have transitioned
out of high concentration of hydrothermal staining. |
1041 |

|
2581 |
Spaghetti worms on age 1 lobates. Seeming even less sedimented
than we have seen before. |
1042 |
-1407 |
-1073? |
|
|
Predominantly Spaghetti worms in some locations on lava flows,
crinoid swimming by, no anenomaes or crabs. Collapse off to starboard
side. |
1042 |
|
|
|
|
At edge of deep collapse off starboard side in shelly lobates.
Can see hole in lobate crust off to port. Going off regular heading
to investigate. Collapse is coming into view on camera now. Broken
up surface underneath (on floor), large collapse, looks like
bathtub rings in the wall and seeing a large lava tube with rubble
in the bottom. Collapse looks like it is 5m deep. Seeing bathtub
rings on the walls, age 1 lobates |
1044.5 |
-1383 |
-10724 |
|
2582 |
At sampling station 6. Down in collapse, sampling from edge.
Can see both orange and white staining on the edge. We're just
10m away from the Spaghetti worms area. |
1047 |
-1334 |
-10724 |
|
2580 |
Underway on a heading of 070°. Just took Sample
3361-6 - piece of lobate crust from the rim of a collapse.
Large piece sitting on top of baskets right now because it won't
fit into any. |
1049.5 |
|
|
|
2578 |
Can see lots of hydrothermal staining. In pillows here. Not
seeing any shining of glass off the surfaces and lots of sediment,
mostly orange staining to the sediment locally, but other places
it is just pelagic sediment. Seem to have passed a contact.
(Confirmed by looking on Alvin video.) |
|
|
|
|
2577 |
Have reached a local high. Kipuka of older material as a
ridge in the axial material that shows up on Argo data? |
1051 |
-1223 |
-10668 |
|
2579 |
Heading off of summit platform. In age 2 pilows with good
ornamentation. Definitely a lot more sediment. As we came out
of lobates, we came into an area with a distinctive concentration
of hydrothermal sediment in crevices and cracks down in pillows. |
1053 |
|
|
|
2595 |
Age 1.5-2 pillows, good ornamentation, elongated forms. |
1054 |
|
|
321 |
2592 |
Changing course, not going to go all the way to WP3. Heading
toward WP4, highly ornamented age 2 pillows. Hoping to cross
contact in 100m or so. Lots of elongate pillows too. |
1057 |
-1210 |
-10568 |
|
2576 |
Back over hydrothermally sedimented lobates. Must be coming
back into younger flow soom. Lots of orange staining down in
pockets. Some pillows too. Look to be age 1.5-2. Sits just off
contact according to our last passing. |
1058.5 |
-1240 |

No more hydrothermal staining. Just seeing good pillows,
age 1.5-2. |

More Spaghetti worms in center of the axis on lobates. Definitely
not seeing much sediment here (sort of gradient on lobates).
Broken up in spots. Good fracturing to the surfaces in localized
areas. Other areas are completely unfractured. |
1102 |
-1332 |
-10407 |
|
2579 |
Very nice age 1 lobates with small collapses. Leaving Spaghetti
worms area (still a few Spaghetti worms but not as many as about
1 minute ago). |
1103 |
|
|
251 |
2581 |
At WP4. We are deviating from the path to head at 270°
for 100m or so to try and pick up contact again. Still age 1
lobates but more ornamented. |
1104.5 |
-1365 |
-10371 |
|
2582 |
Local patches of sediment on age 1 lobates and some broken
up surfaces on tops of lobates, also white staining. Heading
slightly down slope. |
1106 |

Same lava flow but transitioning into more pillows here,
ornamented with buds, suggesting we are near edge of flow. |

Underway again. Still in age 1 lobates. |
1117.5 |
|
|
|
2584 |
Age 1 lobates. Fixes aren't good. Seeing small breaks in
the shell of the lobates every once and a while. Sediment dusting
looks a little bit higher here than it has in previous areas
of the flow but I believe this is because we just passed an extinct
hydrothermal chimney. Also rarer ornamented pillows interspersed
throughout the lobates. |

Passing over a small collapse. Have picked up track line
again. Now we are passing over another small collapse. Lots of
pieces of broken up lobate shell down in collapse. |
1124 |
|
|
|
|
Nice bathtub rings inside of collapse. Out into lobates for
10m and then another collapse. There is a series of collapses
here. See a 3m high lava pillar, lots of bathtub rings on the
side. |
1126 |
-1335 |

Out of area of collapse for 2 minutes. Now we see more again.
Seeing some shrimp in the water. |

Bottom of this collapse has ribbon-folded sheet flow and
a nice pilar. |
1127 |
-1340 |
-10095 |
|
|
Coming about inside of collapse away from 000° heading
to take a sample of sheet flow at base of collapse. Collapse
is large; sub fits in it easily. Can see bath tub rings on the
wall. Can also see lots of broken up pieces with white and orange
staining on them as we enter the collapse itself. Will avoid
them for sampling. We are on a pilar delta that comes out from
the wall with bathtub rings on it. |
1136 |
-1338 |
-1010? |
|

Underway again from sampling station 7 (said 8 on tape).
Sample 3361-7 - small piece of sheet flow ~5
cm in longest dimension into basket 6a. |
1139 |
-1342 |
-10034 |

In lobates, some local collapses but not as big as what we
were just in. Small amount of hydrothermal staining/sediments
down in crevices, but predominantly pelagic sediment here. |

Age 1 lobates. Same as we have been seeing. Some small bits
of hydrothermal sediment in pockets but primarily pelagic sediment.
Also areas of white staining are more pervasive on the lavas. |

Age 1 lobate with occasional bulbous pillows. Not much in
the way of collapses in last couple of minutes. Everything looks
a little less disrupted. |
1146 |

Primarily pillows here. Same age. Elongated and bulbous forms.
Not much ornamentation. |

Contact: Somewhat more sediment on lobates
here. Essentially at WP5. Seeing more sediment, but still some
glass shining through. Age 1.5 ornamented pillows transitional
to lobates. |

here. Dig. Pic #9. |
1155 |
-1375 |
-9579 |
|

Over age 1.5-2 lobates. Lots of sediment in pockets. Not
seeing much glass. Believe contact was just befor WP5. Would
put it at the 2610 m Sea Beam contour. |
1157.5 |
-1424 |
-9529 |

Age 1.5-2 terrain. Primarily pillows, some low-lying lobates.
Some ornamentation to pillows. Definite sediment pockets on our
way to WP6. |

Essentially at WP6. In age 2 pillows and lobates. Heading
for WP7. |
1200 |
|
|
|
2597 |
Over age 2 pillow lavas. My sense is that there was a gradient
of sediment cover between WP5 and 6, although this may also be
because of change from lobates to pillows. Ship fix: 873m 073°
to WP7. |
1204 |
-1763 |
-11245 |
|
2593 |
Over age 2 pillows, some elongate trending off to the sub
at 240°. Darn, these peanut butter sandwiches are dry. |
1205 |
-1694 |
-11256 |
|
2599 |
Contact: Came into age 1 lobates transitional
to pillows in the last 10m. Lots of ornamentation to pillows
and relief to the sea floor. Definite small bits (isolated pockets)
of sediment on this lava flow. |

Taking sample number 9. In age 1 pillows transitional to
lobates. |
|
|
|
|
|
Have just done some surgery on sample 6. We have thrown away
about 2/3 of it. The remaining 1/3 is in the sampling arm. |
1217 |
|
|
|
|
Underway from sampling station number 9. Did two things there.
A) Sample 3361-9 into basket 5a. It was a piece
of lobate shell with orange hydrothermal staining on at least
one surface; B) Sample 6, the big one sitting across many baskets,
had broken into two pieces so the larger of the two was pitched.
The rest went into basket 3b (which is where sample 5, a little
white-stained bud, also is). |
1220.7 |
|
|
075 |
2601 |
In glassy age 1 lobates transitional to pillows. |
1222 |
|
|
|

Still in age 1 lobates. Seeing some pockets of white staining
on cracks on the surfaces of the lavas. Also some orange sediment
pockets. Ship fix: 630m bearing 082° to WP7. |

Big dropoff, turning the sub. 186m 286° from WP8. Collapse
in lobates, will try to sample. Older lobates, lots of broken-up
material, not seeing bottom very well, quasi bathtub rings along
walls, orange staining in most places of exposed surfaces. Sample
12 will be a chunk of lobate. |

13m out from WP8. In age 1.5 lobates. Most lobate shells
here are broken up but not too badly. There is a fairly uniform
dusting of sediment here but steeper surfaces are glassier; can
still see glass shining through. At WP8.Alvin and ship fixes:
570m 090° to WP9. Heading back across the axis. We had just
been at the top of that small mound. The collapse we sampled
was at the summit. |

Contact: Back into young stuff. Pillows,
transitional into lobates. Very shiny glassy surfaces. Big mama
fish about 0.5m long off to port. Can't see kipukas of older
pillows, so flow is relatively thick here. |

than a sharp contrast. It does appear to be the older pillows,
age 1-1.5 here. |
