The photo at left shows Guam on the starboard horizon, as we were returning to land on Sept. 15th. After our gear was safely unloaded onto a flat-bed truck, Susan and I caught a bus with our colleagues to the Guam Hilton. We had the good fortune to relax for a day, including snorkeling in the warm clear waters, and then we had to say goodbye. In Japanese there are so many different ways to say goodbye, but I am hoping that we can say "Jaa, mata" (jahh-mah-tah), which is an informal way of saying "see you again." This cruise was an incredibly enriching experience - both scientifically and culturally. Susan and I look forward to working on our samples and data back at home in Woods Hole.<br />

14-Sep-2010. Today our Chief Scientist Kojima-san returned to Snail site to recover our JAMSTEC collaborators’ demersal plankton pump on Dive 1228. Accompanying Kojima-san on the dive was our cruise mascot, “Gori-san” (shown in photo). We are hoping that Gori-san brought us good luck and that we will have a lot of biology work to do this evening, the last night at sea. I would like to again thank the Captain and everyone on board R/V Yokosuka who helped make this cruise such a great success. Arigatou gozaimasu (ah-ree-gah-tohh goh-zah-ee-mah-soo).<br />

You can see the diversity of rock types collected on the cruise in the photo below (sulfides on left and basalts on right). Today I want to highlight something interesting that I learned during this cruise about how I use the English language. I learned that I often use expressions and idioms that are exclusive to native American English speakers. I learned over the past two weeks to use words with more of the correct meaning in a dictionary (or, in Japanese, “jisho,” pronounced gee-sho). I had planned on titling today’s blog “Icing on the cake” because we recovered the current meter mooring, and we now have data for the near-bottom flow during our larval collections. I talked with a couple of the scientists in the computer room, and we could not come up with a Japanese expression for “icing on the cake.” However, we did come up with an expression for Nobu being “tickled pink” – “hashagu” (ha-sha-goo) in Japanese.Stace Beaulieuhttp://www.blogger.com/profile/11028123964011959074noreply@blogger.com1tag:blogger.com,1999:blog-7753162321516149286.post-58017040849242506692010-09-13T09:37:00.000-07:002010-09-13T09:37:36.355-07:00Women working at sea12-Sep-2010<br />

The science party has nine women, including our collaborator Florence Pradillon from JAMSTEC (see photo inside Shinkai before Dive 1226). While Florence was down on the seafloor, Susan and I worked on deck to clean our mooring gear for the shipment home. We were kneeling a lot, as you can see in the photo below.

Today Ringo responded as usual to our acoustic release and surfaced during daylight (photo right). However, Paul was down on center stage on the seafloor, situated near the top of a hydrothermal mound with a lot of topography all around. He did not want to leave the spotlight of our acoustic transducer. Finally, we were able to get a good angle to send the release command, and Paul lifted off the bottom. Most of the crew and science party went to the bow to wait and watch in the dark. Paul gave us such a light show with a strobe, green glow sticks, and reflective tape, that we saw him before he broke the surface. The photo upper left is Paul’s recovery on deck, and you can see his reflective “P.”Stace Beaulieuhttp://www.blogger.com/profile/11028123964011959074noreply@blogger.com0tag:blogger.com,1999:blog-7753162321516149286.post-90326664714228680872010-09-13T09:22:00.000-07:002010-09-17T04:42:23.205-07:00Dive to inner space<div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhdVMHSg7t8JJNyfcuxsxsg-P8ujYhGHyXsAs78pa5wYlklCvKyneEvEvmvGHsskZS9P3trHVQV5ahyphenhyphenam06kmKAURy3r7DTU41_nFy8JAeDcbRbgicp28NSLL46yjrsu2jSG_zop7bn7VtF/s1600/Susan_Shinkai_dive_suit.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="200" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhdVMHSg7t8JJNyfcuxsxsg-P8ujYhGHyXsAs78pa5wYlklCvKyneEvEvmvGHsskZS9P3trHVQV5ahyphenhyphenam06kmKAURy3r7DTU41_nFy8JAeDcbRbgicp28NSLL46yjrsu2jSG_zop7bn7VtF/s200/Susan_Shinkai_dive_suit.jpg" width="146" /></a><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhHHAAZfDOwc4_7UTh5S07TxYVGackGbfSwESzFgsvfIUyAM5IisQWQFvL0UN5e3VlEL_HsZ7pEWbMn8CffBUe9dpK_NeVEBRH98tbESsw16l7T8Ll3EpFYrY6lsF_Xv_WhpOsjv1A3adgc/s1600/top_lab_Shinkai_Dive1225.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="146" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhHHAAZfDOwc4_7UTh5S07TxYVGackGbfSwESzFgsvfIUyAM5IisQWQFvL0UN5e3VlEL_HsZ7pEWbMn8CffBUe9dpK_NeVEBRH98tbESsw16l7T8Ll3EpFYrY6lsF_Xv_WhpOsjv1A3adgc/s200/top_lab_Shinkai_Dive1225.jpg" width="200" /></a><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh5OP0cucBI8ZUTgeAw26Zf9MGQrrggBGC_za8ZvOVxssgGN_6Aq1K45SKrj8iXoui8A4HeIBepyIEF7JglXhw-4ks_Z_YvMIDOfxbkz8VvM7ib38ubYkCWXUEG4wxLs2BiJyI2DK4BnoNf/s1600/scientists_Shinkai_sample_basket_Dive1225.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"></a></div><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj_fsWbxZakA6XGlDcsgLddKq2WJ263a49HJu2DBWurkqZjUEKu2z3j_omhkJtZFwVRfgHmhUTbu3Q3Wzo-Cm3unkd2-WVj7iRMe2UoX0JLGObMzyFZBw4TMtTRVAD-9X4dP_L1A4V9QShU/s1600/Dive1225_sampling_Pika.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"> </a></div>10-Sep-2010. Today, Susan went on Shinkai 6500, Dive 1225 to Pika Vent. Just like an astronaut dons a space suit, Susan wore a special flame-retardant suit required for divers in Shinkai (photo 1). One thing about diving to the deep sea that is very different than in space, however, is that satellite transmission does not penetrate through the water column. You can’t get a GPS position directly on the seafloor. The Shinkai group uses acoustic navigation to track the Shinkai during a dive. In photo 2 you can see the Navigation Lab, with Chief Scientist Kojima-san speaking with the navigators and our Expedition Leader Sakurai-san next to the plotter. The navigation enabled Shinkai to go directly to Pika Vent for biological sampling (photo 3). After the dive, the scientists eagerly collect samples off the Shinkai’s basket (photo 4).<br />

While the Shinkai was down on the seafloor, Susan and I were preparing for the last pair of pump mooring deployments. I had a moment to kick back in the hangar and make my last splice of the cruise. I also enjoyed working with students, including MiHye Seo (photo right), to teach them how to work with the lines and other mooring gear.<br />

Today I am so thankful and appreciative of the opportunity to dive to the seafloor at Archaean Vent. We were successful in placing the JAMSTEC demersal plankton pump near an active vent with a robust faunal community. In the photo taken before the dive, you can see me and my collaborator Hiromi Watanabe standing next to the pump on the Shinkai basket (the pump has reflective tape on the frame). Accompanying me on Dive 1223 were pilot Chida-san and co-pilot Yanagitani-san (see photo inside of Shinkai). The third photo below shows sampling at one of the active black smokers atop the Archaean sulfide mound.<br />

Today we successfully recovered the first of our plankton pump moorings. The pump worked flawlessly, and you can see in the accompanying image that there was a lot of material collected onto the filter. We can’t tell you yet what we found, but suffice it to say that we and our colleagues spent many hours processing the sample – including video of larvae swimming. We had to stop in order to get a couple hours of sleep before the second pump mooring recovery.Stace Beaulieuhttp://www.blogger.com/profile/11028123964011959074noreply@blogger.com1tag:blogger.com,1999:blog-7753162321516149286.post-29075643408355143312010-09-07T06:06:00.000-07:002010-09-07T06:06:52.419-07:00First Shinkai Dive of the cruise<div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgHHliiRSz6sB0I5_2Aq5EyQb0vsWS11pCMQ6c5tqegFUsp29Th2Y8l5FepSUw4Q27v5hLWs3n9vlJzHDcTV3_SItCG1KslAJ0DErVnDzlRyYYboUv5UOyWVJOvhN6T5BuFgA88O2EnY1fv/s1600/Shinkai_Dive1220_recovery-7.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="200" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgHHliiRSz6sB0I5_2Aq5EyQb0vsWS11pCMQ6c5tqegFUsp29Th2Y8l5FepSUw4Q27v5hLWs3n9vlJzHDcTV3_SItCG1KslAJ0DErVnDzlRyYYboUv5UOyWVJOvhN6T5BuFgA88O2EnY1fv/s200/Shinkai_Dive1220_recovery-7.jpg" width="133" /></a></div>Today was the first dive of the cruise for the submersible Shinkai 6500. Our colleague, Hiromi Watanabe, and two pilots went down to Snail site. They observed all three moorings at the seafloor. These dives to hydrothermal vents in the southern Mariana Trough are funded by the Japanese multi-disciplinary program TAIGA (Trans-crustal Advection and In-situ biogeochemical proceses of Global sub-sea floor Aquifer).

This ambitious feat was made possible due to months of planning ahead of time, then meeting yesterday with the Captain and officers to discuss the mooring configurations, and today by the excellent skills of the crew on deck.

This region is a back-arc spreading center - the back-arc of the Mariana Arc and the Mariana Trench, where the Pacific Plate is subducting under the Phillipine Plate. You can learn more about the geophysics in this region in a recent paper by <a href="http://www.agu.org/pubs/crossref/2010/2009GC002719.shtml">Becker et al. (2010) Geochem. Geophys. Geosyst., 11, Q04X13, doi:10.1029/2009GC002719</a>. The southern Mariana back-arc was recently listed as a region of "highest international priority" for hydrothermal studies by the InterRidge Working Group on Long-Range Exploration (<a href="http://www.interridge.org/WG/Exploration">http://www.interridge.org/WG/Exploration</a>).Stace Beaulieuhttp://www.blogger.com/profile/11028123964011959074noreply@blogger.com1tag:blogger.com,1999:blog-7753162321516149286.post-26265084417416912492010-08-20T05:15:00.000-07:002010-08-20T05:17:08.736-07:00Equipment and supplies shipped to Guam<div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjAwVf0Rxop-aDCEGBPMLLWjKMfb_aVjZsZnY70wgNr5F7alP2AvOjUwZ3vUSV_WlwX8pnXl5-uBh3BpFrJaoO2BIuO4T9E8E0z0rCutQ9kMURfO8y6FcokoS7QU1Gk_1wJs6dTppMAyVfq/s1600/shipping_boxes_Mariana_cruise.JPG" imageanchor="1" style="clear: left; float: left; margin-bottom: 1em; margin-right: 1em;"><img border="0" height="150" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjAwVf0Rxop-aDCEGBPMLLWjKMfb_aVjZsZnY70wgNr5F7alP2AvOjUwZ3vUSV_WlwX8pnXl5-uBh3BpFrJaoO2BIuO4T9E8E0z0rCutQ9kMURfO8y6FcokoS7QU1Gk_1wJs6dTppMAyVfq/s200/shipping_boxes_Mariana_cruise.JPG" width="200" /></a></div><div>On Tuesday, we shipped our instruments, mooring gear, and supplies to the ship's agent in Guam. Susan and I have spent weeks gathering all the things that are now itemized on a big spreadsheet and distributed into 11 packages weighing 4000 lbs! Why does the shipment weigh so much? The heaviest "package" is actually a rack of steel anchor weights (for the plankton pump moorings, which will be described in a later post). The plankton pump boxes, with extra batteries, each weigh over 300 lbs. I am writing on one of these in the attached photo. Also in the photo, you can see our red boxes (heavy with mooring hardware), black totes (with lab and office supplies), and miscellaneous other gear such as polypro line and buckets. </div>Stace Beaulieuhttp://www.blogger.com/profile/11028123964011959074noreply@blogger.com0tag:blogger.com,1999:blog-7753162321516149286.post-67686015248630489302010-08-15T10:23:00.000-07:002010-08-15T10:23:21.951-07:00Testing instruments<div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj80sygCN8Bn0gM0K3XlQ4490BCVBO3NkgUZkBQ6ysVx8y2CVhilKMZ2YHQX6vyMGEfNk-aO3i3ZDA_jd_DMrV42sKwqPkVbJ91KmxMPoBW0Gn6Wj8yehSczU7iH7DUGR6y8kaXDXTOsg_y/s1600/current_meter_dock_test_Aug2010.jpg" imageanchor="1" style="clear: left; float: left; margin-bottom: 1em; margin-right: 1em;"><img border="0" height="200" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj80sygCN8Bn0gM0K3XlQ4490BCVBO3NkgUZkBQ6ysVx8y2CVhilKMZ2YHQX6vyMGEfNk-aO3i3ZDA_jd_DMrV42sKwqPkVbJ91KmxMPoBW0Gn6Wj8yehSczU7iH7DUGR6y8kaXDXTOsg_y/s200/current_meter_dock_test_Aug2010.jpg" width="150" /></a></div>In preparation for our cruise, Susan and I have been conducting bench and dock tests of the instruments that will go on our moorings. For example, the photo shown here was taken during our test of an Aanderaa RCM8 current meter. This current meter is an older style, with a rotor and vane. It has served our lab group well on previous cruises, and we hope it will do the same at 3000-m depth in the southern Mariana Trough. The current meter will help us know whether the near-bottom flow was along- or across-axis during our plankton pump sampling near on- and off-axis vents.Stace Beaulieuhttp://www.blogger.com/profile/11028123964011959074noreply@blogger.com0
