Whole plate Flex array for detailed studies Greater density near trench Multiple deployments Absolute pressure gauges Shallow water - facility for future Deploy first instruments in 2010 near N. ETS site 2 summers for each deployment to study structure Accelerometers at some sites Balance of “broadband” vs shortperiod in flex array?
