The construction of traditional seismic installations is time consuming and requires bulky materials, limiting the number of stations that can be installed from a single vehicle, and limiting the ability to install stations in remote locations. Recent technological improvements have made possible the direct burial of sensors and a reduction in the size of the necessary solar panels. We take advantage of these advances to create a field box/shipping container (the Carnegie Quick Deploy Box, or ‘QDB’) that will greatly simplify seismic deployments. The goal of systems like the QDBis to have everything needed for a station installation (except battery and shovel) contained in a single box for shipment, and to be able to leave everything (except the shovel) in that box during the deployment. The QDB is small and lightweight enough to be checked as airline luggage, and to be transported by foot on a frame backpack. The solar panels can be mounted on top of the QDB, or pole-mounted. External cables plug into watertight bulkhead-fitted plugs on the outside of the QDB. Our prototype QDBs (modified Pelican Cases) have been tested in Alaska, Nicaragua, and Italy without failure due to flooding or power.  The setup can be completed in a matter of minutes once the sensor is installed. QDBs such as ours will make possible a dramatic increase in the number of stations that can be installed, while also significantly decreasing the cost of deployment per station by reducing vehicle time, fuel, personnel time, and shipping costs.
