Description
- Summary
- PNRA (Italian Research Programme in Antarctica) - During the austral summer 1988-89, the second geophysical survey was conducted in Antarctica collecting magnetic, gravimetric, seismic reflection and refraction data in the South Pacific Ocean and in the Ross Sea. The first part of the survey has been dedicated to the area of the Balleny Islands in the South Pacific Ocean, where 3,053 km of profiles have been collected. The research has been sponsored by the National Research Program in Antarctica (PNRA), headed by the Italian ENEA. The 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 = 14 sec Air-Guns: - Total Volume = 45.16 l - Pressure = 140 bar - Depth = 6 m
