3. Investigate the distribution and nature of hydrocarbon seepage and biodegradation along the CA margin.
4. Identify and map hydrocarbon/tar sources and related features along the CA margin.
5. investigate the fate of dissolved hydrocarbons in the waters along the CA margin.
6. Deploy in-situ incubation devices for microbial growth, for recover in 2013.

Science Activities

1. Jason operations including coring, water sampling, hydrocarbon sampling, surveys.

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.
