Cascadia Initiative Year 3, LEG 3 (At26-02, EM122). Recover 30 Lamont Doherty Earth Observatory Ocean-bottom Seismometers (OBSs) of 3 different types: •10 TRM shallow-water OBSs with Trillium compact 3-component absolute pressure gauge installed at depths from 200-1000m (nominal). Recovered using remotely operated vehicle Jason. •10 Trawl-Resistant Mount (TRM) shallow-water OBS with Trillium compact 3-component seismometer, absolute pressure gauge (APG), acoustic release/pop-up buoy with Jason backup. •10 LDEO deep water OBSs with APG. Recover by sending an acoustic release command to drop the anchor. OBS then floats to the surface a nominal rate of 50m/min. Referred to as LDEO-DW below. •Iftime allows, discover and recover 2 Woods Hole Oceanographic Institution deep water OBSs. Additional Activities: Acquire swath bathymetry, including water column data, in transit between all stations and port. Acquire other underway data (e.g. meterology, acoustic doppler current profiler).

Submarine Exploration and Evaluation of Petroleum Seeps (SEEPS) (AT26-06, EM122). 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.
