Dive R495  
      Dive Plan: 1) Fluid sampling of southern caldera/upper South Rift Zone vents - Mkr-108, Mkr-113, Castle, Joystick, Coquilles, Bag City. 2) Suction sampling: Mkr-113 Marcus/Moyer, Bag City Moyer/Juniper, Diatom mat on new lava - Tunnicliffe.  
      3) Recover and deploy MTR's at Mkr-113 and Bag City. 4) Sulfide sampling at Castle. 5) Finish Imagenex survey, geology traverse south.  
      ROPOS Configuration: Hot Fluid Sampler, Suction sampler (j1 - j4 and 1 - 4), Niskin, Imagenex, cameras and rock purse  
      Note: Nav fixes not edited in the logs. All fixes were logged, regardless of accuracy. Use the dive plots to determine actual positions.

7 15 1519 250 423757 5086591 date is wrong on the overlay - it is one day behind  
7 16 1519 296 423757 5086593 coming around to get on south side of pillar, lots of white staining but no apparent venting  
7 16 1520 11 423772 5086587 no venting on south side of pillar  
7 17 1519 47 423772 5086585 possible marker in distance, moving around to check it out  
7 18 1520 6 423778 5086589 good fixes, lots of floc but no marker yet

7 24 1518 251 423776 5086589 heading back to first place we saw venting, worms are visible on top of pillar  
7 25 1520 230 423778 5086580 stopped on top of pillar, appears that there is a little bit of venting, very slow trickle of non shimmery water.  
7 27 1519 318 423301 5087530 heading NW, 318.2 to the place we started looking for Mkr-108  
7 29 1521 338 423764 5086599 low lying pillar with cracks leading up to it, but no shimmering water, continuing  
7 32 1521 323 423756 5086603 good fix, has us right under cage

7 36 1520 270 423305 5087533 jagged, crumbly flow  
7 37 1521 271 423738 5086591 good fix, due west of target by about 40 meters but no pillars in sight  
7 38 1520 89 423726 5086587 heading straight east over jumbled ropy sheet flow  
7 39 1521 86 423749 5086583 good fix  
7 40 1520 86 423743 5086575 possible vent out of big hole, but we cant get to near it to check it out  
7 44 1521 81 423771 5086586 good fix, and some vent coming out of the base of a pillar, we are going to continue the transect to the east and then come back if there is nothing better  
7 47 1522 352 423773 5086605 venting coming out of hole with worms surrounding it. Dave has decided to sample here  
7 49 1523 29 423312 5087530 we are 20 meters at 329 from the target but have decided to sample from what appears to be two holes  
7 51 1523 73 423772 5086607 placing the temp probe inside one of the holes,  
7 56 1524 136 423781 5086593 good fix, but the temp probe bumped into the side of the vent and now it has collapsed into a swirling mass of floc and shimmering water, the temperature did reach 9 C though.  
8 7 1524 132 423771 5086608 temp is around 13.6 C for max

9 9 1500 15 423542 5087430 we are now up at 150m and there is definitely a plume, lot o' particles, Dave deduces that there must be more venting going on near Mkr-108 (which we never found) than we discovered  
9 12 1519 141 423542 5087430 we are down right under the cage, and found the venting that we first discovered when we got here
