List of U.S. states by coastline
| List of U.S. states by coastline ： ウィキペディア英語版|
This is a list of U.S. states ranked by their coastline length. States with no coastline are not included.
Two separate measurements are used: method 1 only includes states with ocean coastline and excludes tidal inlets; method 2 includes Great Lake coastline and the extra length from tidal inlets. For example, method 2 counts the Great Bay as part of New Hampshire's coastline, but method 1 does not. The figures suffer from the inaccuracy inherent in all attempts at measuring coastlines but are nevertheless useful for comparison.
*The data for method 1 were retrieved from a CRS Report for Congress 〔("U.S. International Borders: Brief Facts" ), Congressional Research Service, November 9, 2006〕 using data from ''U.S. Department of Commerce, National Oceanic and Atmospheric Administration, The Coastline of the United States, 1975''. This is based on measurements made using large-scale nautical charts. The figure for Connecticut was arrived at separately and may not reflect the correct comparative distance. These numbers exclude the Great Lakes coastlines.
* The data for method 2 are from a list maintained by the Office of Ocean and Coastal Resource Management of the National Oceanic and Atmospheric Administration (NOAA). The state coastline lengths were computed by an unspecified method that includes tidal areas not included in the first method.〔("States and Territories Working With NOAA on Ocean and Coastal Management" ), Office of Ocean and Coastal Resource Management, February 03, 2011〕 These numbers also include the Great Lakes coastlines.
