Description

Processed seismic reflection data and associated files from Roger Revelle voyage RR1508: 16 May - 18 June 2015. The research voyage  aimed to characterise the thermal regime of the gas hydrate systems on the southern Hikurangi margin east of New Zealand. Data were processed using the Globe Claritas processing software.

All SEG-Y files have the following binary header word definitions, required for loading data:

Start time: 2-byte integer: Bytes 105-106

Trace Sample Count: 2-byte integer: Bytes 115-116

Sample Interval (microseconds): 2-byte integer: Byte 117-118

CDP Number: 4-byte integer: Bytes 5-8

CDP X location: 4-byte integer: Bytes 197-200 (Note: Coordinates are in metres of UTM Zone 60S, WGS84 Datum)

CDP Y location: 4-byte integer: Bytes 201-204 (Note: Coordinates are in metres of UTM Zone 60S, WGS84 Datum)
