In situ microbial sampler from Craig Taylor's group. Not using this sampler. An RNA collector device will be used- one similar (if not identical) as was used during the November 2003 Cary/Luther leg and our cruise in April 2004 Luther - We will also be deploying the original echem system as we did last year from the Alvin - this one will be under the titanium ball as before.- needs 4 serial wires and 12v power from Alvin. Shank - RatCam time-lapse camera system with relay transponder and 6-ball float package Tolstoy-pressure gauge recovery and redeployment with Alvin Liz Goehring- education and outreach coordinator for Ridge 2000, 4 crab traps to be deployed and recovered by Alvin. One day deployment. Marv Lilley's temp instrument, wt 20lbs. Was deployed Nov. 04. Alvin will recover. Recruitment blocks to deploy Internal Sphere equipment: Test 6-7 April Laptop computer Digital SLR camera (already gas tested) Shipboard Transponder Nav Equipment/Nav: UBSL Nav Other Requirements: Night Work: Luther -1-2 CTD casts Maya Tolstoy OBS work-12 long term deployments and 12 recoveries, and 3 short term deployments and recoveries, requires 8-10 nights of 4-8 hrs each. Checking on night ops for Shank/Mullineaux and on release/recovery info for sed-traps. Tolstoy- will use hydrowire to test OBS releases at maximum depth~2500m. Releases will go in cage for the test. Liz Goehring- will be conducting student projects.They will have a total of 24 instruments, made of 7-8 cm long PVC tubes. These instruments will be in mesh bags attached to the hydrowire. They will be at 3 different depths with 8 instruments at each depth. Deepest depth 500m. One cast for the cruise. More information on Student Projects: There will be four student experiments and one ClassroomToSea Laboratory on this upcoming cruise. The actual student proposals are posted on the SEAS website: http://www.ridge2000.org/SEAS/ 1) "Crabs' catch of the Day" - bait and deploy 4 crab traps to determine crab feeding preference. Will use Alvin to deploy and retrieve. Will need to coordinate with Pilot and on-board scientists on the days (2) of this experiment. 2) "Water, water everywhere!" - exploring the relative strength of two different shapes (cylinder and pyramid) and two different materials (steel and PVC) in withstanding water pressure. Students will construct containers to be tested at three different depths (150, 300, 450 meters). Containers and controls will be placed in mesh bags to be attached to the hydrowire. Containers will house foam which will serve as one of the measures of the effect of pressure. Will need assistance from deck crew/SSSG to handle the hydrowire. May also need assistance opening any non-imploded containers (we're bringing our own Sawzall but will need to know where to do this work safely). 3) "Archaea Classification" - this experiment piggybacks on Costa Vetriani's work. Samples of microbes will be collected from different temperature regimes, and then be cultured on board. Students will hypothesize what types of microbes are present in each sample based on results from cultures. Dr. Vetriani will help with this experiment and the work will be carried out in his lab. 4) "Tubeworm Distribution" - this experiment also piggybacks on work to be done at various tubeworm colonies. Two colonies will be located, and samples (images and vent chemistry) will be taken at intervals throughout the colony, to characterize TW distibution in relation to vent flow. Dr. Shank will likely help with this experiment. Follow-on work will involve processing data images and chemsitry data. Will also work with Dr. Luther on this. In addition to the student experiments, we will also conduct a lab - the ClassroomToSea lab, in which we will collect a sample of vent mussels, dissect them on board, and post data to the SEAS website. Students will follow the same procedures on surface water mussels, in their classrooms. Then with the two datasets, they will be able to compare similarities and differences between shallow-water and deep-sea mussels. Again, this will not require any extra equipment except to arrange to bring a sample of mussels back in a biobox, as space is available. We will work with Dr. Shank in his lab during the dissections. There will be two teachers, in addition to myself, coordinating and conducting these projects, and writing about them for the website. Friday April 29th 8:10- 8:30 PST, Call from the ship to National Junior Science and Humanities Conf. and patch into Alvin, Liz G. will initiate the call, (time at EPR +6). Notes: Hazmats will be compressed gases for use by Vetriani's group (Nitrogen, and a Carbon Dioxide/Hydrogen mix). Gases and MSDS/Hazmat forms were loaded in San Diego in January. Luther and Shank: Chems and forms on ship. Remaining materials will be offloaded in Seattle in June.
