Science Supplied Equipment

Are you supplying equipment to be used on HOV Jason?

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 devices (non electrical) similar to those used previously, 3) gas collection tubes (used on Alvin), 4) incubation chambers, and 5) Pressure compliant sampling cyclinders.

1) Please contact Rich Camilli regarding TETHYS. 

2 and 3) The other items are being fabricated or modified.  None are electrical devices.  We anticipate some pressured samples from a new style of flux measurement system currently under development.

4) Incubation chambers were deployed by Jason on AT15-53, Jason lowerings J2-599 and J2-600. We are currently fabricating gas injector frames to be used in the continuing deployment of the incubation chambers, to introduce our tracers into the sealed incubators in situ.  We are working with the marine facilities ship at Scripps to fabricate these.

5) We may bring several (100 to 300 mL in volume) pressure compliant sampling tubes to retain in-situ pressure upon sample retreival.

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, at the sea floor, or on an elavator.

Will this equipment be deployed off the vehicle?  yes

If yes, please describe how the equipment is intended for deployment.
The incubation devices are currenlty at the sediment surface.  These devices will be sealed, placed on a frame (that we are currently fabricating, and will bring with us), and valves manipulated to introduce substrate for the microbes.

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

How long will the deployment be?  15  Days

Will the equipment be recovered by the same vehicle?  yes

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 conducting 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.
