Salt marsh vegetation-mediated response of nitrogen cycling to the Deepwater Horizon spill, Chandeleur Islands, Louisiana from 2017-05-30 to 2018-06-13

This dataset was generated from a study conducted in the Chandeleur Islands, a chain of barrier islands off the coast of Louisiana which were subjected to a gradient of oil deposition following the spill. Starting in May 2017, we collected sediments from plots dominated by black mangrove and smooth cordgrass at a lightly oiled site and a moderately oiled site subjected to a range of oiling to determine the impact of woody encroachment and oiling on sediment denitrification and dissimilatory nitrate reduction to ammonium (DNRA).

本数据集源自一项在尚德利尔群岛（Chandeleur Islands）开展的研究。该群岛为路易斯安那州近海的障壁岛链，在溢油事件后受到梯度化石油沉积的影响。自2017年5月起，研究团队在覆盖梯度油污染范围的轻度油污染样地与中度油污染样地内，采集以黑红树（black mangrove）和互花米草（smooth cordgrass）为优势植被的沉积物样品，以此探究木本植被扩张与油污染对沉积物反硝化作用及异化硝酸盐还原为铵（DNRA）的影响。
