HANGIN’ OUT
The packer tests for this hole are going very well, but are time consuming because several levels have to be checked. As a result, the scientists have time to catch up on their data collection, report writing, and other official business. However, they are also finding some time to relax and unwind. I found the chemistry laboratory to be a very busy place today.
Here is a partial update for today given by Adam Klaus, Expedition Project Manager/IODP-USIO Staff Scientist (USA):
The first two sets of hydrologic tests are nearly completed. During the first test, the packer was set in the top of the uniform lower portion of borehole (at ~3140 mbrf; ~472 mbsf). The packer was then raised to ~3110 mbrf (~442 mbsf) for the second test. The final test will be conducted a bit further up the hole at ~3095 mbrf (~428 mbsf) and should last the rest of the morning. I think that our next step will be to conduct a test to determine if the CORK casing and centralizers can enter past the damaged 10 3/4-inch casing and what techniques we might use to help this.
Countdown to Astoria: 10 days

 ARTIST’S VIEW. Shoichi Kiyokawa, Sedimentologist (Japan), took some time to relax outside during this afternoon’s perfect weather to draw the drilling derrick. He is sitting on one of the lounge chairs on top of the science stack. Keir Becker, CORK Hydrologist (USA), is working in the background.

 MUSIC CONNOISSEUR. Bob Wheat, Marine Laboratory Specialist (USA), is well prepared for a 2 month expedition aboard the JOIDES Resolution! He always has a new music selection to listen to as he works in the chemistry lab.

|
|
 CROSSWORD BREAK. Mark Nielson, Physical Properties Specialist (USA), takes a much needed break while his samples are being analyzed in the chemistry lab. He is sitting in the microscope lab working on his crossword puzzles.

 SAMPLING THE CAKE. Marion Dumont, Organic Geochemist (Sweden), is enjoying the quiet that comes with working the night shift in the chemistry laboratory. She is preparing to cut a sample of one of the squeeze cakes (see yesterday’s entry). She will take a small sample back to Sweden to analyze the sediment for its organic carbon content as part of her research.

 PORE WATER SAMPLES. The chemistry laboratory has been a very popular place today! Takuroh Noguchi, Inorganic Geochemist (Japan), has been collecting pore water samples by squeezing sediments for the last couple of days. Here, he is preparing his samples to be taken home for further research.

|
 PHOTOGRAPHIC EVIDENCE. Bill Crawford, Image Specialist (USA), has to be very versatile. Not only does he shoot photos of shipboard life, the drilling operations, and the laboratory work, but he also has to take pictures of all samples that are taken by scientists for analysis. Here he is taking photographs of key sedimentary structures for Shoichi Kiyokawa (Japan) so that he can use them in his report on the sedimentology of the cores from Hole 1301C.

|
 CARBON TESTING. Bob Wheat, Marine Laboratory Specialist (USA), is busy analyzing samples from Hole 1301C for their carbon content using a Coulometrics 5011 carbonate carbon analyzer. I noticed that the tunes in the chemistry laboratory provided a great working atmosphere!

 LARRY: RADIO AND PERSONEL EXPERT. I have gotten to know most of the people on the ship, but as I was working on the name list for the group photo, I was stumped on 5 people. I checked with several people who helped with one or two people. Finally, I went to the expert, Larry Jarillas, Radio Operator (Philippines), who had all the answers. Thanks Larry
