The U.S. Geological Survey (USGS) announces the online availability of a
new report. Entitled "National Assessment of Shoreline Change:
Historical Shoreline Change Along the North Coast of Alaska,
U.S.-Canadian Border to Icy Cape," the study presents long-term
shoreline change rates between (c1947 to c2000s) every 50 m along the
mainland and barrier island coastlines for a portion of the north coast
of Alaska. The full report is online: http://pubs.usgs.gov/of/2015/1048.
Beach erosion is a persistent problem along most open-ocean shores of
the United States. Along the Arctic coast of Alaska, coastal erosion is
widespread, may be accelerating, and is threatening defense and
energy-related infrastructure, coastal habitats, and Native communities.
As coastal populations continue to expand and infrastructure and habitat
are increasingly threatened by erosion, there is increased demand for
accurate information regarding past and present trends and rates of
shoreline movement. There also is a need for a comprehensive analysis of
shoreline change with metrics that are consistent from one coastal
region to another. To meet these national needs, the U.S. Geological
Survey is conducting an analysis of historical shoreline changes along
the open-ocean sandy shores of the conterminous United States and parts
of Hawaii, Alaska, and the Great Lakes. One purpose of this work is to
develop standard, repeatable methods for mapping and analyzing shoreline
change so that periodic, systematic, and internally consistent updates
regarding coastal erosion and land loss can be made nationally.
This report on shoreline change along the north coast of Alaska, between
the U.S.-Canadian border and Icy Cape, is one in a series of regionally
focused reports on historical shoreline change. Previous investigations
include analyses and descriptive reports for the coasts of the U.S. Gulf
of Mexico, the Southeast Atlantic, California, the New England and
Mid-Atlantic, portions of Hawaii, and the Pacific Northwest coasts of
Oregon and Washington.
