Introduction

“Huddle”-testing sensors before field deployment is a key part of any seismic experiment.  Huddle-testing involves testing almost all components of the field station, for many stations, in parallel.  The number of stations that can be tested at one time is limited only by availability of personnel and lab space.

Huddle-testing potentially reduces crew time spent in the field, cost of the experiment and the need to revisit sites.  Huddle-testing improves crew consistency and most importantly, the likelihood of successful station deployments and survival.

All equipment, especially dataloggers, sensors and cables, are cleaned and comprehensively tested when they arrive at the PIC, regardless of whether the equipment are newly delivered from the manufacturer or being returned from an experiment.  PASSCAL makes every effort to ensure that all equipment are operating to the manufacturers specifications, and that all on-board consumables (such as betteries, etc) are fresh.
