We recommend active-source data sets be archived in PASSCAL's PH5 format. SEG-Y format is also acceptable. Both formats require a data report as described in point 3 below. Please also include copies of any field notes, observer reports, or sensor axis orientation offsets, if they occurred.
Prior to sending your data to PASSCAL, be sure to fill out a mobilization form, to obtain an assembled dataset id number. We can't process the data without this code.
PH5 requirements
Shot/Source information - in dep file format, from the pocus program, TSP input file format, or in spreadsheet form:
time & identification of each shot/source
latitude & longitude of each shot/source
elevation of shot/source
size of shot in kg or magnitude of source
depth below surface of shot/source
comments (if applicable)
Receiver/Station information - in dep or TSP format, or in spreadsheet form:
identification of each station
serial number of receiver
manufacturer and model of receiver
type of sensor attached
latitude & longitude of each station
elevation of station
comments (if applicable)
General information about experiment - please submit a PDF file:
principal investigators names & institutions
experiment name & nickname
paragraph describing purpose of experiment
paragraph describing layout of instruments
All raw data files - can be in one of these forms
.trd files
.ref files
compact flash disks
raw disk images
SEGY requirements
If submitting seismic waveforms as shot gathers in SEGY format, additional stages of data reduction may be included, such as a final stack profile. All appropriate header values should be filled in according to the SEGY standard.
Please include a description of disk or other media contents, and instructions on how to read them. In addition to the Data Report, please include all information on the geometry of the experiment (metadata). Traces should be time-corrected whenever possible, and you should supply a discussion of whether timing corrections were applied to the data. If no timing corrections were applied, please include copies of the ref2segy log files.
