Ivotuk generator and comms enclosure
Engine generator and communications enclosure for the Ivotuk Autonomous Research Platform.
System Generator icon Solar icon Wind icon Battery icon Diesel generator/battery system augmented with a wind turbine and photovoltaic system.
Location Ivotuk lies at the southeastern edge of the National Petroleum Reserve on the North Slope, well in the interior of Alaska (68.5 N, 155.7 W).
Description Ivotuk is a small research site supporting autonomous instrumentation that requires electrical power 24 hours a day, 365 days a year.In addition, the ability to transfer the scientific data to the researchers home institution in near real time is built into the design along with the capability of remotely monitoring the scientific equipment, as well as the power system.

The system supports the power and data transfer needs of research instrumentation for Dr. Walter Oechel's Global Change Research Group at San Diego State University and the data transfer needs of Dr. Larry Hinzman of the Water and Environmental Research Center of the University of Alaska, Fairbanks.

Data GCRG's experiment consists of a suite of carbon flux and meteorological instruments. For more information on the specific instruments and data collected visit GCRG's web site at http://www.sci.sdsu.edu/GCRG/index.html.

WERC maintains a meteorological tower at Ivotuk. For more information on those data and instruments please visit the WERC web site at http://www.uaf.edu/water/
Comms A StarBand satellite system provides two-way, near real-time Internet connectivity. A pair of RF transceivers supports communications between the science instrumentation and the StarBand system. An Iridium modem provides back-up communications.
