Erosion Rates of Islands in Barataria Bay, Breton Sound, and Terrebonne Bay, 1988-2013

We quantified the shoreline erosion of 46 islands in Barataria, Breton Sound and Terrebonne Bay for before and after the DWH oil spill to determine how much shoreline was lost, if the losses were temporary, and if recovery/restoration occurred. The erosion rates were then calculated for five intervals: (1) the 2010 initial post-oiling interval up to December 2010, (2) the early 2011 interval from December 2010 to spring/summer 2011, (3) from the beginning of the first interval to the end of the second (spring/summer 2011), (4) from spring/summer 2011 to the end of 2012, and (5) from May 2010 to the end of 2012.

本研究量化分析了巴拉塔里亚湾、布雷顿湾与特雷邦湾共计46座岛屿在深水地平线（Deepwater Horizon, DWH）漏油事件前后的海岸线侵蚀状况，以明确海岸线侵蚀总量、侵蚀是否具有暂时性，以及是否存在恢复或修复过程。随后针对五个时间区间计算了侵蚀速率：(1) 2010年漏油后初始时段（截至2010年12月）；(2) 2011年初时段（2010年12月至2011年春夏）；(3) 首个时段起始至第二个时段结束（即2011年春夏）；(4) 2011年春夏至2012年末；(5) 2010年5月至2012年末。
