Research goals of the BGP require instrumentation with unique sensing

and data storage capabilities. Data loggers and all sensing devices must

be low power and low cost devices, capable of operation in a wet and rugged

environment, and have large data storage. Consequently, electronic

instrumentation used at Bench Glacier has been specifically

designed and built for this project. Some examples follow.

“Gophers” Down hole instrument pods with sensors to measure water: conductivity, turbidity, flow velocity, and pressure.
	“Stamp-loggers” Data loggers built around a basic programmable stamp. The four channel loggers will operate for one year on a single 7 amp-hour battery. Data from the four sensors is stored 4 times per hour with a high level of precision. Data can be collected by simply swapping a 2 MB storage chip.
Radio transmitters – Inexpensive radio transmitters ($15 per unit) were installed in each data logger box. A simple receiver will locate the data logger boxes during Spring after burial by 4-6 m of winter snow.
