Alaska Shorefast Ice: Interfacing Geophysics With Local Sea Ice Knowledge And Use
Dissertation (Ph.D.) University of Alaska Fairbanks, 2011 This thesis interfaces geophysical techniques with local and traditional knowledge (LTK) of indigenous ice experts to track and evaluate coastal sea ice conditions over annual and inter-annual timescales. A novel approach is presented for con...
