1404 Sub in the water. Sipper check @ 1400 meters ­ everything okay. DLK check @ 1800 meters ­ error “serial port timed out” message recorded.

1527 Sub reaches bottom 4361 X 78081 ­ landed in collapse @ 2502 meters.

1535 Began searching for major pair lost on previous cruise 4374 X 78048, 2503 ­ no luck.

1537 Turned off sub power to DLK.

1603 Began direct transit to elevator holding LVWS (Eric Wommack’s Large Volume Water Sampler).

1605 Found elevator in hole ~ 4537 X 78342, 2513 heading 142.

1615 Heading to ASC to set unit down for repositioning, removed one weight.

1630 DLK talk with surface re: error message.

1638 Began moving elevator: 4514 X 78324 heading 128 (transit).

1655 In transit, 4550 X 78559, 2509 m observed giant field of serpulid worms.

1705 Deploying LVWS at “Mussel Bed” site: began temp probing of area – noticed shimmering water in hole ­ this is where we will deploy.

1720 Deploying LVWS nozzle at shimmer near mussels: 4578 X 18549, 2503 m

1723 Pumping Sipper @ 5.9° ­ 6.4°C ­ Sipper 2

1737 Changed tapes to #2.

1752 Began pumping LVWS (problem with positioning: was not clear which position was "purge" and which was "pump" from our angle ­ must specify in dive plan).

1754 Transiting to Q vent for Alvinella collection (320 M, 334 range and bearing from elevator site).

1803 Securing DLK ­ still not responding ­ serial port time out error.

1810 Arrive @ Q vent: Western spire 4438 X 78827, 2506 alt 5.8 m.

1825 Pumping Sipper

1826 Sipper (tube) 1: 31-38°C

1829 Sipper (tube) 3: 31-54°C

1832 Sipper (tube) 4: 27-29°C

1834 Sipper (tube) 5: 77-126° C (probe may have touched chimney on this one).

1835 Deploying slurp pump to catch Alvinella for Artie (RNA later) chambers.

1835 ­ Slurp 1

1852 ­ Slurp 2

1854 ­ Slurp 3

1856 ­ Slurp 4

1857 4 worms in chamber one. Pumping RNA later ­ successful.

1910 Began slurping for worms for chamber 3.

1910 ­ Slurp 1

1915 ­ Slurp 2

1917 ­ Slurp 3

1920 ­ Slurp 4/5

1924 3-4 worms in chamber three ­ pumping took ~60 seconds, total.

1926 Sampling large Alvinella clump for forward biobox chamber.

1932 Spotted small beehive chimney just above Alvinella colonies 130–303°C effluent temperatures Sipper 6 @ 294°C (270-301).

1942 Collected small chimney ­ stored in small, grey biobox.

1944 In chimney scar: Sipper 7 @ 140-228°C Sipper 8 @ 234°C.

1949 Trying to position chamber (fry pan) 4437 X 78827, 6.4 meters altitude.

1955 No good, piece broke off & ledge unstable ­ attempts to carve out flattened edge also fail as entire structure seems friable and unstable.

1957 Changed tapes to #3.

2002 Set up at new site on Q: 4435 X 78824, 2504 heading 054 small beehive with temp of 193°C.

2005 Lost chimney, very friable, not stable for placement @ Q vent.

2009 Leaving Q, returning to elevator (LVWS).

2031 At LVWS, digital images taken: plunger is in crevice, lots of shimmer.

2038 Pump off, elevator secured, nozzle retrieved.

2039 Elevator released.

2045 Sipper 9 @ 5.6°C from LVWS nozzle location.

2049 Transiting to Tika, main clump, to retrieve Cavanaugh’s “Fries” samplers #28 and #30.

2104 Spotted Tika 4604 X 78227, 2509 m depth saw low vents near tubeworms ­ looks good for future ASU fry pan deployments.

2107 Sighted Fries #28/#30 and collected both into aft biobox.

2114 Cleared for surface after being advised to look for lost major pair.

2122 Weights away ­ no majors.
