Alaska: West Beaufort Sea Coast (Colville River to Point Barrow) transects with short-term (ST) linear regression rate calculations for the exposed coast

This dataset consists of short-term (~33 years) shoreline change rates for the north coast of Alaska between the Colville River and Point Barrow. Rate calculations were computed within a GIS using the Digital Shoreline Analysis System (DSAS) version 4.3, an ArcGIS extension developed by the U.S. Geological Survey. Short-term rates of shoreline change were calculated using a linear regression rate-of-change method based on available shoreline data between 1979 and 2012. A reference baseline was used as the originating point for the orthogonal transects cast by the DSAS software. The transects intersect each shoreline establishing measurement points, which are then used to calculate short-term rates.

本数据集涵盖科罗维纳河（Colville River）至巴罗角（Point Barrow）之间阿拉斯加北海岸的短期（约33年）海岸线变化速率。速率计算依托地理信息系统（Geographic Information System, GIS）完成，采用由美国地质调查局（U.S. Geological Survey）开发的ArcGIS扩展模块——数字海岸线分析系统（Digital Shoreline Analysis System, DSAS）4.3版本实现。研究基于1979年至2012年的现有海岸线数据，通过线性回归变化速率法计算海岸线短期变化速率。DSAS软件生成的正交断面以参考基线作为起始基准点，这些断面与每条海岸线相交以生成测量点位，随后利用这些点位计算短期海岸线变化速率。
