Meteorological and geomorphological influence on harbor seal haul-out distribution behavior using drone imagery
… conditions affect seal haul-out site use. Using drone surveys, high-resolution elevation models and slope maps were produced for major haul-out sites. Drone surveys from 2021 to 2023 provided seal counts during key life history stages—pupping and molting—with seal identified manually or using …

Survey Techniques to Examine Morphological Evolution of Coastal Regions
… backpack and occasionally with a lidar equipped drone. Surveys of the northern region of interest also were collected with a stationary terrestrial lidar mounted on the dune. The observed morphological events include the destruction and formation of a cusp field during which there was 1.4 m of …

Analyzing remote sensing-derived normal difference vegetation index to predict coastal protection by Spartina alterniflora
… This study combined field measurements and drone surveys to develop methods for quantifying vegetation drag, focusing on Spartina alterniflora (S. alterniflora), a smooth cordgrass native to the study site: Waquoit Bay National Estuarine Research Reserve. The drag of a single plant is …
