Surface currentmapping high-frequency radarswere installed along the northwest corner of Alaska during the open water periods of 2011–2013.A combination of wind and solar renewable energy inputs supplied electricity to a single radar site operating at Point Barrow, Alaska, via an off-grid remote power module (RPM). The radar at Point Barrowwas able to simultaneously collectmeasurements of ocean surface currents,measure the position and velocity of passing vessels, and provide meteorological data in real time. This paper provides a summary of the performance of the power module from 2011 to 2013 and vessel detection results from 2013with corresponding Automated Identification System(AIS) data. The RPMprovided infrastructure to meteorological stations, highfrequency radars, and AIS in a resilient and robustmanner and serves as an example of how the multi-use capability of integrated sensormodules can provide enhancedmaritime domain awareness and persistent surveillance capabilities in remote Arctic environments.
