3. Investigate the variability in composition of seeping hydrocarbons at sites along the CA margin.
4. Investigate the distribution and nature of hydrocarbon seepage and biodegradation along the CA margin.
5. Identify and map hydrocarbon/tar sources and related features along the CA margin.
6. Identify, map and sample microbes and chemicals associated with historical waste disposal practices.
7. Conduct sampling for additional in-situ incubations.

Science Activities

1. Jason operations including coring, water sampling, hydrocarbon sampling, surveys, slurp sampling.
2. Sentry operations including multi-beeam mapping, photosurveys, mass specrometric surveys.
3. CTD casts  (24 place rosette) for water collection.
4. Rate measurements using identical protocols as for SEEPS 07, SEEPS 09, and SEEPS 11 (note the use of radioactive materials).
5. Coring activities using multi-corer and gravity corer. 
6.  Sampling for in-situ incubations using custom vacuum incubators.

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 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?
Has the pressure housing been tested per Alvin Pressure Test requirements? no
