SIO

SIO has 39 broadband instruments that they operate as part of the OBSIP pool. The LC4x4-LP is an ocean-bottom instrument designed for use in seismic experiments that use either passive sources (e.g., earthquakes) or active sources (e.g. seismic air-gun surveys) to generate signals. The general characteristics of these instruments include:

− 24-bit A/D converter with precision time base
− large capacity solid-state memory
− EdgeTech independent acoustics
− Trillium-240 seismometer
− Differential Pressure Gauge (DPG)
