1400 Sub in the water

1420 At 542 m, Checked DLK-SUB3 system, working properly. Checked Sipper electrode (#1), flow cell electrode (#2), two macrowand electrodes (#3 and #4), all electrodes working properly.

1543 Got to Bio-Vent: X, Y 45343, 79197, Heading 080, Depth 2504 m.

1544 Scan checked electrode #1.

1549 Set up at Bio-Vent. Get ready for ElectroChem scans and Sipper samples.

1554 ElectroChem scans with electrode #1 and #2 for Sipper sample #1. Sipper temperature probe read 44°C

1602 Fired Sipper #1, 31–40°C.

1604 ElectroChem scans with electrodes #1 and #2 for Sipper sample #2. Sipper temperature probe read 41–47°C.

1607 Fired Sipper #2, 32–33°C.

1609 ElectroChem scans with electrodes #1 and #2 for Sipper sample #3. Sipper temperature probe read 24–32°C.

1614 Fired Sipper #3, 27°C.

1619 ElectroChem scans with electrodes #1 and #2 for Sipper sample #4. Sipper temperature probe read 35–40°C.

1628 Fired Sipper #4, 46–47°C.

1632 Left Bio-Vent and headed to Q-Vent.

1643 Scan checked electrodes #1, #2, and #3 on the way to Q-Vent.

1649 Arrived Q-Vent.

1655 Set up at Q-Vent. Get ready for ElectroChem scans and Sipper samples.

1658 ElectroChem scans with electrodes #1 and #2 for Sipper sample #5. Sipper temperature probe read 35–41°C.

1705 Fired Sipper #5, 39°C.

1707 ElectroChem scans with electrodes #1 and #2 for Sipper sample #6. Sipper temperature probe read 24–30°C.

1712 Fired Sipper #6, 37°C.

1716 ElectroChem scans with electrodes #1 and #2 for Sipper sample #7. Sipper temperature probe read 47°C.

1720 Fired Sipper #7, 45°C.

1721 ElectroChem scans with electrodes #1 and #2 for Sipper sample #8. Sipper temperature probe read 27–34°C.

1723 Fired Sipper #8, 33°C.

1724 Started sampling worms.

1736 --- Changed to tape #2. ---

1748 Grabbed worms with arm. Put in ARTIE chamber#1, closed and pumped RNA Later. There were 4–5 worms in chamber #1.

1805 Grabbed worms with arm. Put in ARTIE chamber #2, closed and pumped RNA Later. There were 4–5 worms in chamber #2.

1818 Grabbed worms with arm. Put in ARTIE chamber #3, closed and pumped RNA Later. There were 3–4 worms in chamber #3. We were not sure if the RNA Later was pumped properly. It couldn’t be seen clearly from the release valve.

1829 Tried to deploy Shank HOBO. Not successful. The temperature was too low. Then decided to move and find a new spot.

1836 Deployed Shank HOBO: X, Y 4421, 78799, Heading 040, Depth 2,503 meters.

1837 Left Q-Vent and headed to Tica. Scanned check electrode #1 and #2 on the way to Tica.

1906 Arrived Tica, X, Y 4609, 78153, Heading 044, Depth 2,509 meters,

1919 Dropped four baby traps into Riftia.

1934 Set position to recover ASU unit.

1937 On the side of the ASU unit, ElectroChem scans with electrodes #1 and #2 for Sipper sample #9. Sipper temperature probe read 53°C.

1940 --- Changed to tape #3. ---

1941 Fired Sipper #9, 23°C.

1942 On the top of the ASU unit, ElectroChem scans with electrodes #1 and #2 for Sipper sample #10. Sipper temperature probe read 16–45°C. Fired Sipper #10, 81°C.

1950 Recovered the ASU unit and accidentally dropped it.

1951 At the scar, ElectroChem scans with electrodes #1 and #2 for Sipper sample #11. Sipper temperature probe read 57°C

1955 Fired Sipper #11, 80–87°C.

2011 Went closer to the bottom and found the ASU unit. Put the unit in the front box of large biobox and left the site, headed off-axis.

2020 Recovered Cavanaugh off-axis Fries (#43, 44) and put them into the rear chamber of large biobox.

2022 Left Tica and headed to Bio-9.

2030 Arrived Bio-9 X, Y 4747, 78176, Heading 000, Depth 2,504 meters.

2034 Recovered Cavanaugh Fries #49, #48 and put them in small biobox.

2039 Recovered Cavanaugh Fries #47, #50 and put them in middle chamber of large biobox.

2053 Left the site, 2,511 meters and dropped the weight.
