Project Goals
• Automate and sustain observations in Monterey Bay
• Increase the spatial resolution of regular and sustained observations (Pt Lobos CTD time series)
Team Members
• Francisco Chavez• Robert Fuhrmann• Drew Gashler• John Graybeal• Rich Henthorn
• Reiko Michisaki• Tom O’Reilly• John Ryan• Erich Rienecker• Brian Schlining
Coupled with DMO AUV Operations
• First sustained AUV science operations
• Leverage the efforts of other projects
• Low risk, high return operations.
• Near surface operations ease navigation requirement.
• Regular operations build sample size for reliability studies.
Year 2 Milestones
• Begin data acquisition operations (3/1)
• First data loaded into SSDS (6/1)
• New AUV payload integrated (8/1)
• Infrastructure for extended operations. (ongoing)
• 2003 Data set processed and loaded into SSDS (12/31)
Progress towards milestones (Data acquisition)
• Regular 25 km data acquisition operations have commenced.
• Vehicle flies sawtooth pattern between the surface and 250 meters. Passes within 500 m of M-1 mooring.
• Data sets have been acquired in April, May and June.
Progress towards milestones (Data handling)
• Data processing toolbox modularized.
• Data processing utilizes NetCDF format for compatibility with SSDS.
• First data sets have been processed.
• Processing procedures are a work in progress.
Progress towards milestones (Data handling)
• Data management system designed.
• Some elements have been implemented.

Data Tracking
SSDS
1) Archive data and mission files
2) Send metadata to SSDS which describes: a) the mission b) the instruments on the AUV c) the data files - location of files - formats - what produced each data file
