Dataset for: Five year of Deepwater Horizon oil spill effects on marsh periwinkles Littoraria irrorata

This dataset reports the density and mean length of marsh periwinkles Littoraria irrorata at oiled and non-oiled sites in coastal Louisiana, Mississippi, and Alabama from 2010 to 2015. Data include the length of one individual snail measured at each site. These data are associated with the publication: Zengel S, Weaver J, Pennings SC, Silliman B, Deis DR, Montague CL, Rutherford N, Nixon Z, Zimmerman AR (2016) Five years of Deepwater Horizon oil spill effects on marsh periwinkles Littoraria irrorata. Mar Ecol Prog Ser https://doi.org/10.3354/meps11827.本数据集记录了2010至2015年间，美国路易斯安那州、密西西比州与阿拉巴马州沿海受油污染与未受油污染样点内沼泽滨螺（Littoraria irrorata）的种群密度及其平均体长。本数据集包含各采样点中单只滨螺的体长测量数据。上述数据关联的已发表学术论文为：Zengel S、Weaver J、Pennings SC、Silliman B、Deis DR、Montague CL、Rutherford N、Nixon Z、Zimmerman AR（2016）《深水地平线漏油事件对沼泽滨螺（Littoraria irrorata）的五年影响》，刊载于Mar Ecol Prog Ser，DOI链接：https://doi.org/10.3354/meps11827。
