    "descript": "During the summers of 2022 and 2023, U.S. Geological Survey (USGS) researchers conducted underwater surveys aimed at quantifying the impact that past coral restoration by Mote Marine Laboratory had on the reef-accretion process. The surveys were conducted along paired transects representing restored and non-restored areas of eight offshore reefs and three patch-reef sites in the Lower Florida Keys. At each location on each reef, USGS researchers collected images (39,480 images in total) that were used to generate structure-from-motion (SfM) products (point clouds, orthomosaics, and digital surface models), which were used to quantify percent cover of corals and other benthos and topographic complexity.",
