SEDEX2 Topographic and Bathymetric Data

Cross-shore transect data collected with backpack based real-time kinematic GPS was collected of the beach and dune at intervals of daily to ~monthly as part of the Sandbar Aeolian Dune Exchange Experiment (SEDEX2) in Oysterville, WA, USA. Bathymetric data is also provided from Oysterville, WA which was collected using the Coastal Profiling System (Ruggiero et al., 2005).Landscape measurements published here are from a single cross-shore transect (SEDEX2 Line 17) in XYZ format. The XYZ data represents point data in the Washington State Plane (meters) horizontal coordinate system and a vertical datum of NAVD88 (m), with the date of data collection described within the filename.

作为美国华盛顿州奥伊斯特维尔沙洲风成沙丘交换实验（Sandbar Aeolian Dune Exchange Experiment，SEDEX2）的一部分，研究团队借助背包式实时动态全球定位系统（real-time kinematic GPS），以每日至约每月的间隔采集了海滩与沙丘的跨岸断面数据。本数据集同时提供了来自该区域的水深地形数据，该数据采用海岸剖面测量系统（Coastal Profiling System，Ruggiero等，2005）采集。本文发布的景观测量数据源自单条跨岸断面——SEDEX2 17号测线，数据格式为XYZ格式。该XYZ数据为采用华盛顿州平面（米为单位）水平坐标系与北美垂直基准面1988（NAVD88，米为单位）的点位数据，数据采集日期信息包含于文件名中。
