The CREWES experiment at the Priddis test site in July 2012 was designed to test different acquisition methods and recording systems. The project was named Pulse-Probe to describe one of the source methods being tested. The equipment used were two Aries SPMLite recording systems, one with single SM7 3-component 10Hz geophones; the other with strings of 6 32CT 10Hz geophones podded and similar strings spread over 10 metres, an ION Scorpion with Vectorseis MEMS sensors, and Autoseis autonomous nodes each with 3 SM24 10Hz vertical geophones. Also tested were some GS-20DM 3- component geophones planted under sand bags instead of using spikes for coupling, and a single 3-component downhole geophone deployed in the well on the property. Sources for the survey were the University of Calgary Envirovibe, a Mertz M22 provided by Geokinetics, and dynamite shots of several charge sizes and depths. This paper makes some comparisons between the Aries and the Autoseis autonomous node recording systems.
