Science Supplied Equipment


Are you supplying equipment to be used on HOV Jason?
yes

Has this equipment been used on Jason 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.

1) Tethys, 2) flux measurement device (non electrical) used with Alvin, 3) gas collection tubes (used on Alvin), 4) incubation chambers.

Please contact Rich Camilli regarding TETHYS.  The other items are being fabricated or modified.  None are electrical devices and none are pressurized.



Does this equipment use an external pressure housing?  no

If yes, what is the pressure rating? 
and test pressure? 

Or has the pressure case been tested per Alvin Pressure Test requirements?  no

Housing schematic with dimensions and include air and water weights.

Does the equipment have an associated computer or control panel for remote operation from the personnel sphere?  no

Air weight of this equipment? 

Does the equipment require data or a power interface from the vehicle?  no

Does this equipment require hydraulic inputs from the vehicle?  no
Hydraulic schematic of the equipment requirements.

Does this equipment require manipulation?  yes

If yes, please describe how the equipment is to be manipulated.

Except for tethys, the other items can be manipulated with the Jason manipulator, and stored in the basket.



Will this equipment be deployed off the vehicle?  yes

If yes, please describe how the equipment is intended for deployment.
The incubation devices will be placed in the sediment, or at the sediment surface.  We may want a digging tool of some sort to create the hole for them.

If yes, will the equipment be disconnected from the vehicle and left in situ?  yes

How long will the deployment be?  700  Days

Will the equipment be recovered by the same vehicle?  no

If recovering equipment deployed with another vehicle, provide pressure rating: 
and test pressure: 

Does this equipment use any glass spheres for either buoyancy or as pressure housings?  no

Hazardous Material


Will hazardous material be utilized? yes

Describe deployment method and quantity:
We will use a small amount of methane gas, ~100mL, for the incubations.  Methane is a flammable gas, but the small volume being used poses little concern, and is less quantity than we typically bring up in natural samples.

Additional Information

Brief operations description or comments:
We will be conducted several sorts of operations including sampling at known hydrocarbon seeps, explorations at various sites (details still being determined), deployment of incubation chambers, and potentially mapping and photoimaging.
