The results of the first years data analysis employing data collected during the NGENDEI seismic experiment in the southwest Pacific are presented. This experiment tested the DARPA Marine Seismic System and verified the improved signal-to-noise ratio achieved by burying the instrument within the oceanic crust. The experiment, which took place on the Deep Sea Drilling Project Leg 91, was designed to test the Marine Seismic System MSS in a realistic environment near an active trench environment. An earlier test of the system in the northwest Pacific had been unsuccessful because of difficulties in drilling an acceptable borehole in the seafloor. The MSS was recorded aboard the DV glomar Challenger for several days of earthquake, refraction and environmental noise experiments. The subsequent deployment of an autonomous recording package on the seafloor was successful.
