Area of habitat still above water per decade of projected sea level rise for islands in two study areas off Florida's Gulf coast

Sand beaches are dynamic, making it difficult to accurately predict habitat loss from sea level rise (SLR). We mapped sand beach habitat based on two datasets - a remotely sensed land cover and hand-digitized aerial imagery collected concurrently with digital elevation data. Data include the predicted area of beach habitat still above water (units = number of pixels) from SLR per decade, for 3 SLR scenarios, based on two mapping methods, for 12 barrier island beaches and 4 control islands off Florida's Gulf Coast.

砂质海滩具有动态变化的固有特性，这使得准确预测海平面上升（Sea Level Rise, SLR）引发的海滩生境流失量极具挑战。本研究基于两类数据集完成砂质海滩生境制图：一类为遥感土地覆盖数据，另一类为与数字高程数据同步采集的人工数字化航空影像。本数据集涵盖佛罗里达墨西哥湾沿岸外的12处障壁岛海滩与4处对照岛屿，基于两种生境制图方法与三种海平面上升情景，统计了每十年间由海平面上升导致的仍维持于水位以上的海滩生境预测面积，单位为像素数量。
