High-marsh epifauna densities within references and ice-rafted sediment deposits, Rowley, MA.

Following a historic bomb cyclone (Winter Storm Grayson) in January of 2018, a large volume of ice-rafted sediment was patchily deposited on the surface of salt marshes in the Great Marsh, MA. In May of 2018, twenty patches of ice-rafted sediments and paired reference sites (i.e., no sediment deposition) were delineated. In May 2018, August 2018, and August 2019, samples were collected to examine how ice-rafted sediments affected vegetation, infauna, and epifauna recovery over time. This specific dataset focuses on epifauna species counts, with the primary species including: Melampus bidentatus, Littorophiloscia vittata, and Orchestia grillus. This dataset is complete and please see our publication (https://doi.org/10.1007/s12237-021-01023-z) for more information.

2018年1月，历史性炸弹气旋（冬季风暴格雷森，Winter Storm Grayson）过境后，美国马萨诸塞州大沼泽（Great Marsh, MA）的盐沼表面斑块状沉积了大量浮冰搬运沉积物。2018年5月，研究人员划定了20处浮冰搬运沉积物斑块及其配对对照样点（即无沉积物沉积区域）。分别于2018年5月、2018年8月及2019年8月采集样本，以探究浮冰搬运沉积物随时间推移对植被、底内动物（infauna）与表生动物（epifauna）恢复过程的影响。本数据集聚焦于表生动物的物种计数，所涉及的主要物种包括：双齿耳螺（Melampus bidentatus）、带纹潮虫虱（Littorophiloscia vittata）以及奥氏钩虾（Orchestia grillus）。本数据集内容完整，更多详细信息可参阅我们的发表论文（https://doi.org/10.1007/s12237-021-01023-z）。
