Data collected in 2008-2022 to assess nearshore subtidal community responses to increased sediment load during and after removal of the Elwha River dams, Washington State, USA

Data are time series of substrate grain size, vertical relief, and measures of abundance (e.g., density, percent cover) of the nearshore subtidal (5-16 m depth)...本数据集涵盖近岸潮下带（水深5-16米）的底质粒径、底床垂直起伏，以及丰度表征指标（如密度、盖度）的时间序列数据。
