Science objectives

The University of Minnesota research group has the following objectives:
1. Hydrothermal vent fluid sampling. The vent sampling will involve direct acquisitoin of fluid samples using Alvin, but also deployment of time series sampling by remote operation.
2. Chemical sensor deployments will take place in association with vent fluid sampling

Science Activities

To fulfill UM objectives, we will deploy sensor and samplers at sites of high temperature venting, but also at sites of diffuse flow venting.  Vent fluid samples will be processed on board ship. Chemical sensor calibartion efforts will also take place shipboard, before and after seafloor deployment. The UM group will be heavily involved with chemical work while onboard.

Pre-cruise planning meeting: Visit WHOI

The UM group could do either, but we have business at WHOI in the near future

Has this equipment been used on Alvin before?  no

Please give a brief description of the equipment, its intended purpose, the cruise # it was last used on if any and its deployment method.
The UMN team will bring six instruments: 
(1) High-T in situ chemical sensor system. This instrument is used for the high-T hydrothermal vent fouid and will be deployed by Alvin's manipulator.
  The dimension is about 3'' OD x 3' length and weighs about 20 lbs in air and 14 lbs in water.
 (2) Deployable high-T chemical sensor system. This instrument  is used for measure high T hydrothermal chemistry and will be deployed on the seafloor from days to one week. 
    The dimension is about 3'' OD by 2' length and weighs about 18 lbs in air and 14 lbs in water.
(3) Deployable pH Calibrator. This instrument is used for hydrothermal diffuse flow environments and will be deployed to the seafloor from days to one week. 
    The dimension is about 36'' x12'' x12'' and weighs about 60 lbs in air and 40 lbs in water
(4) Mobile pH Calibrator. This instrument is used for hydrothermal diffuse flow environments and will be deployed by the Alvin's manipulator. 
   The dimension is about 12'' x12'' x12'' and weighs about 40 lbs in air and 26 lbs in water
(5) Single gas-tight sampler. This instrument is used to collect the hydrothermal samples and will be deployed by the Alvin's manipulator. 
The dimension is about 17'' x 8'' x 4'' and weighs about 20 lbs in air and 16 lbs in water
(6) Serial gas-tight sampler. This instrument is used to collect multiple hydrothermal fluid sample and can be used by the on line or deployed on the seafloor.
