Morphology, sedimentation, and seismic characteristics of an arctic beach, Nome, Alaska - with economic significances
H. Gary Greene
1970, Open-File Report 70-142
Arctic beaches exhibit characteristics that do not occur on beaches in more temperate zones. In the summer of 1967 morphological, sedimentological, and seismic refraction studies were made on an arctic beach near Nome, Alaska, in order to better define these distinguishing characteristics.Several distinct microrelief structures are developed during ice break-up...
