Description
Summary:The authors describe a new, state-of-the-art data logger for ocean-bottom seismology. This instrument, which they call ORB, is a versatile system that can be deployed in a variety of configurations ranging from a stand-alone ocean-bottom hydrophone with a two-week recording capability to an ocean-bottom seismometer with a one-year recording capability. The data logger has a dynamic range of more than 130 dB, a clock with a stability of a few parts in 10/sup 9/, and a data storage capacity of many gigabytes. ORB is based on a commercially available system (RefTek/sup TM/ 72A-07) that is also used in large numbers by the U.S. IRIS (Incorporated Research Institutions for Seismology) consortium.
