1404 Commence dive — Sipper probe bent at 90° angle as Alvin hit a swell on water entry.

1529 Arrived at bottom 2,610m meters — much particulate matter floating, sponges on basalt.

1537 Tape #1 installed; port manipulator has hard ground, so we decided to use the starboard manipulator for all operations; x=4660, y= 6720, heading = 271

1551 Arrive at Genesis; 2617 meters, x=4584, y= 6758, heading = 253

1603 Small Alvinella area in a large Riftia clump; x=4580, y= 6754, heading = 015, many amphipods; temperature 31°C.

1634 Begin work for Artie 1 with Alvinella.

1641 Worms and their tubes placed in Artie 1.

1644 Top placed on Artie 1.

1645 RNA later added — Alvinella holes too small for the Sipper probe.

1651 Driving to Parigo.

1706 Arrive at Parigo — 2 large hills or mounds (x=4689, y= 6666, heading = 099); one mound about 15 m tall with Riftia and Alvinella at the top; placed Sipper into Alvinella holes (5).

1727 Sipper #1 (sample #1) taken; temp as high as 100°C.

1734 Tape #2 installed.

1735 Sipper #2 (sample #2) taken; temp as high as 119°C.

1745 Sipper #3 did not fire.

1755 Sipper #4 (sample #3) taken; temp as high as 87°C.

1759 Sipper #5 (sample #4) taken.

1805 Sipper #6 (sample #5) taken.

1810 Grab of Alvinella for Bio Box.

1814 Begin Artie 2 with Alvinella.

1829 Artie #2 full of Alvinella.

1833 Fill Artie #2 with RNA Later.

1835 Leave to look for Tevnia, Riftia, mussels, clams; 26 Doppler target; called by top lab to not go to Totem but to go to Grandbonum.

1922 Found Grandbonum. Massive sulfide; x=4795, y= 6965, heading = 155.

1932 Begin measuring temperature around and in Alvinella tubes (5).

1934 Tape #3 installed.

1935 Sipper #7 (sample #6) taken; temp as high as 90°C.

1937 Sipper #8 did not fire; problems with Sipper computer.

1947 Alvinella worms put into Bio Box.

2004 Sipper #9 (sample #7) taken; temp as high as 110°C.

2007 Sipper #10 (sample #8) taken; temp as high as 110°C.

2009 Sipper #11 (sample #9) taken; temp as high as 110°C.

2011 Sipper #12 (sample #10) taken; temp as high as 110°C.

2014 Finished Sipper samples.

2017 Alvinella worms put into Bio Box; temperature after collection up to 30°C.

2020 Sipper #3 (sample #11) taken. Tried to sample orange sulfides (2), but both were lost.

2049 Move to collect Riftia (x=4793, y= 6954, heading = 018); used Fat Albert to measure echem.

2053 Sipper #8 (sample #12) taken.

2058 Collect Riftia and put into Bio Box.

2059-2102 Collect Riftia for Artie 3.

2103 Collect more Riftia for Bio Box.

2111 RNA Later added to Artie 3.

2113 Dropped weights and head up.

2300 Surface.
