The Dangerous Ice Project Jukebox is a National Science Foundation funded project at the University of Alaska Fairbanks (Award Number 0909517). The goal is to understand changing ice conditions on the Tanana River through the combined knowledge of scientists and experienced local river travelers.
Over the winters of 2005-2007 and 2010-2013, groups of river travelers and scientists traveled to potentially hazardous places on the Tanana River near Fairbanks, Manley Hot Springs, and Tanana to document ice conditions and/or measure air temperature, ice thickness, and water temperature, depth and chemical composition. Photo and video documentation of our site visits can be found by clicking on the orange point markers on the map below.
Local experts have provided historical perspective, personal experience, and traditional knowledge about the ever-changing Tanana River. Scientific research is adding information about the dynamics of the river system and the influence of groundwater upwelling on ice conditions. A booklet explaining ice dynamics and travel advice offers information to the general public about how to avoid trouble during winter travel.
This has been a joint project between Elmer E. Rasmuson Library and the Institute of Arctic Biology at the University of Alaska Fairbanks.
