MGL1115 Seismic:Active:OBS:TravelTimePicks
Travel time picks for the mantle refraction, Pn, from NoMelt central Pacific active-source OBS data
This data set consists of travel times for the mantle refraction, Pn, picked from active-source OBS data collected as part of the NoMelt experiment in the central Pacific. The data set is in ASCII format. For each travel time, the shot line number, station location, and shot location are provided. Before picking, the OBS data were filtered with an 8-pole, minimum phase Butterworth filter with corner frequencies of 4 to 15 Hz, and a linear prediction deconvolution was applied using a filter length of 0.2 seconds and a prediction distance of 0.01 seconds. Travel times were then picked by hand on the vertical ground motion components of station gathers. This data set was generated as part of a project called NoMelt: Structure and evolution of the oceanic lithosphere/asthenosphere system. Funding for this project came from NSF grants OCE09-28663, OCE09-27172, and OCE09-28270.
