Seismic station requirements
For global structural studies, stations must be deployed for at least three years, to ensure adequate collection of data from globally-distributed earthquakes. For monitoring of seismic events, permanent stations are needed. These long-term stations should be as low-noise and broadband as possible. They should be located in major gaps of land and island coverage, seperated from existing or potential land-based stations by a distance of about 20 degrees.
Such recommendations were initially made in 1988, at the workshop sponsored by JOI/USSAC, which established the fundamental importance of scienific goals for ocean-bottom seismic observatories and identified the necessary experiments required to unequivocably prove the scientific benefit and technical practicality of a global network of long-term broadband downhole seismometers.
