Description 
Summary

In December 1990 a Crustal Seismic Reflection Profile has been conducted in cooperation with the Department of Scientific and Industrial Research in the area of East Cape, North Island, New Zealand. The objective of the research was to study the lower crustal-upper mantle structure across the convergent margin and extensional back-arc basin of northern New Zealand. During the survey a total amount of 440 km has been covered on 2 lines. The seismic data have been collected with the following sampling parameters: Coverage = 3000 % Sample Rate = 4 ms Shot Interval = 50 m Streamer Length = 3000 m Streamer Depth = 12 m Group Interval = 25 m Number of Groups = 120 Record Length = 16 sec Air-Guns: - Total Volume = 45.16 l - Pressure = 140 bar - Depth = 6 m
