Abstract : The report describes the development and evaluation of two devices for monitoring long-term seafloor foundation settlement and tilting. The LOBSTER(Long-Term Ocean Bottom Settlement Test for Engineering Research) is an instrumented foundation used as a test device, whereas the FMS(Foundation Monitor System) is an instrument that can be attached to any seafloor foundation to be monitored. Data and preliminary analysis are presented from successful foundation deployments for periods of up to 1 year at water depths of 4,120,600, and 1,200 feet in the Santa Barbara Channel area of the Pacific Ocean. The analysis presented includes data from an extensive laboratory program of core analysis and consolidation testing. (Author)
