Purpose | Survey low-angled slope failure off Hawke Bay, and determine nature of the curst beneath Hikurangi Trough. Collect bathymetric, gravity and magnetic data. | ||||||||
Description | Chief Scientists: Keith Lewis, Monty Hampton. Geological and Geophysical data (3dot5khz, 12khz, uniboom, airgun, sidescansonar, 24channel, sonobuoy, airgunmonitor, gravitycore) of field activity L-7-83-SP in Southern Pacific from 12/28/1983 to 01/03/1984 | ||||||||
Location | Continental margin off Eastern North Island and Hikurangi Trough, New Zealand | ||||||||
Summary | multichannel seismic data recorded along a 275 km long profile across the convergent plate boundary forming the eastern continental margin of North Island. Over 5000 shots were recorded. | ||||||||
Comments | GIS tools on best navigation file, l-7-83-sp.054, found cumulative trackline distance to the nearest tens of kilometers is 1480 kilometers.
