Borrowing from classic Newtonian mechanics, the concept of a body\u2019s center of mass is applied to the geomorphic landscape, and the barrier island environment in particular, to evaluate the metric\u2019s potential as a proxy for detecting, tracking and visualizing change. Two barrier islands along North Carolina\u2019s Outer Banks are used to test this idea: Core Banks, uninhabited and largely-undeveloped, and Hatteras Island, altered by the presence of a protective dune system. Findings indicate that for Core Banks, the alongshore change in the center of mass is in accord with dominate littoral transport and wind conditions. Cross-shore change agrees with independent estimates for the island migration rates. This lends credence to our assertion that the mass center metric has the potential to be a viable proxy for describing wholesale barrier migration and would be a valuable addition to the already-established ocean shoreline and subaerial volume metrics. More research is, however, required to demonstrate efficacy.<\/jats:p>","DOI":"10.3390\/ijgi3010049","type":"journal-article","created":{"date-parts":[[2014,1,28]],"date-time":"2014-01-28T03:27:01Z","timestamp":1390879621000},"page":"49-65","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Barrier Island Dynamics Using Mass Center Analysis: A New Way to Detect and Track Large-Scale Change"],"prefix":"10.3390","volume":"3","author":[{"given":"Paul","family":"Paris","sequence":"first","affiliation":[{"name":"Department of Marine, Earth and Atmospheric Sciences, North Carolina State University, 1125 Jordan Hall, 2800 Faucette Drive, Raleigh, NC 27695, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Helena","family":"Mitasova","sequence":"additional","affiliation":[{"name":"Department of Marine, Earth and Atmospheric Sciences, North Carolina State University, 1125 Jordan Hall, 2800 Faucette Drive, Raleigh, NC 27695, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2014,1,27]]},"reference":[{"key":"ref_1","first-page":"17","article-title":"Accuracy of shoreline change rates as deter-mined from maps and aerial photographs","volume":"59","author":"Anders","year":"1991","journal-title":"Shore Beach"},{"key":"ref_2","first-page":"839","article-title":"Historical shoreline change: Error analysis and mapping accuracy","volume":"7","author":"Crowell","year":"1991","journal-title":"J.
