新英格兰的盐沼正在发生变化, and so are the technologies used to monitor their transformations. UNH researchers are now relying on cutting-edge unoccupied aerial vehicles (UAVs, more commonly called drones) that capture aerial images to monitor shifts in marsh vegetation species, indicating changes in the health and longevity of these critical ecosystems.
In a study 发表在《永利app新版本官网地址》杂志上, researchers relied on UAV-derived images of the marshes that used near-infrared color wavelengths combined with elevation data to map various vegetation species within these landscapes. This approach outperformed true-color images even when they were paired with elevation data. The study further demonstrated that the best time of year to capture UAV images for mapping marsh species in our area was early October.
“由于许多司机,沼泽处于危险之中, 包括城市扩张和海平面上升,” explains 迈克尔Routhier他是美国 联合国大学地球系统研究中心 也是这项研究的第一作者. “The use of UAV remote sensing techniques provides a novel way to monitor these ecosystems at very high spatial resolutions not available from conventional aerial or satellite remote sensing techniques.”
盐沼是重要的栖息地. They provide homes and nurseries for numerous flora and fauna, buffer the effects of wave action and storm surge to our coastlines, 捕获沉积物有助于保持沿海水域的清洁, 并充当更大的全球碳循环的汇, Routhier notes. The methods and findings of this research can provide resource managers with insights into how best to monitor marshes over time to help maintain their survival.
