Summary of Field Work: |
We will test an ocean lander and pressure-retaining water samplers in the San Clemente Basin down to a depth of ~ 2,000 m.
Four drops are planned. |
|
Summary of Facility Requirements: |
The lander will be deployed and recovered from the ship's A-frame. It will be identified at the surface by its red flag, strobe light, radio beacon and iridium GPS signal. It will be followed underwater using a Benthos deck box.
The science party will bring a chilled water bath and subsamplers to be set up in interior lab space. A small amount of space is needed for pipetting samples and adding chemicals to the microbes in the seawater. A small filtration station may be needed to be set up by the science party. |

Explanation of Science Party Requirements and Technician Requirements |
We need to test an ocean lander and pressure-retaining water samplers to be used in conjunction with the lander. Four sets of drops are needed to collect water from ~ 2,000 m (as deep as possible in this general location). A small amount of lab space (wet lab) is needed to subsample from the pressure-retaining samplers and set up incubations of microbes. |
