Becker et al. (2010) Geochem. Geophys. Geosyst., 11, Q04X13, doi:10.1029/2009GC002719. 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 (http://www.interridge.org/WG/Exploration).

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.

Since the discovery of deep-sea hydrothermal vents, scientists have been perplexed by the question: How are these vent sites colonized and, more specifically, How are the faunal populations established and maintained at these very discrete and often ephemeral habitats? The cruise in September 2010 will visit three of the Vents (Volcanic) Unit sites in the U.S. Marianas Trench Marine National Monument: South Backarc (also called Snail), Archaean, and Pika. The larval studies that we will conduct with our Japanese colleagues will help address the question of how populations of vent-endemic species are connected at hydrothermal vents within the Monument. For more information about the Monument, which was established in 2009, please see: http://www.fws.gov/marianastrenchmarinemonument/. You can see a map of the Monument on the Friends of the Monument blog: http://marianamonument.blogspot.com/2009/06/mariana-trench-marine-national-monument.html.
