Departure: Sep 25, 2013

San Francisco

Arrival: Oct 16, 2013

San Diego

Operations Area

Santa Barbara and Santa Monica Basins (Possibly off Big Sur and San Diego)
Lat/Lon: 34° 0.0′ N / 120° 0.0′ W
Depth Range: 40 / 1500
Will the vessel be operating within 200 NM of a foreign country? no

Science Objectives

1. Conduct in-situ incubations with devices for microbial growth, deployed in 2011.
2.  Investigate the fate of dissolved hydrocarbons in the waters along the CA margin.
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.
