This spring, the Duke Marine Robotics and Remote Sensing Lab will once again work with Ms Tammy Schooley’s East Carteret High School Advanced Placement Environmental Science (APES) class on a comprehensive marine debris drone project. Last May, the APES class used MaRRS fixed wing and rotary wing aircraft and multi-spectral cameras to detect, identify, and analyze marine debris on the Rachel Carson National Estuarine Research Reserve. During the second part of the effort, the class visited the Reserve to “ground-truth” the aerial data and to remove the debris. The students concluded the project by providing a presentation to local government officials, scientists, and marine debris experts to explain their findings on the scope of the marine debris challenge in Carteret County, and offering their analysis on potential solutions.
The Duke Marine Lab Unoccupied Systems Facility is calculating nearshore marine turtle densities in the Eastern Tropical Pacific by partnering with researchers from the University of North Carolina whose work focuses on gaining a better understanding of the environmental cues that lead to sea turtle mass nesting events (arribadas) in Costa Rica. After using fixed-wing aircraft to conduct aerial transects, the team analyzed hundreds of images and is working with a Californian company to develop software that can be used to automatically identify turtles. Besides developing cheaper, safer, and more effective methods for identifying individuals and calculating densities, this work will support future efforts to conduct broad-scale abundance and distribution assessments in aid of conservation and recovery efforts for these and other protected populations of sea turtles, both in Costa Rica and around the globe.
Our research group teamed up with coastal geologists from Antonio Rodriguez’ lab at UNC Institute of Marine Sciences to map out the terrain of Bird Shoals using drones and lasers (ah, sweet, sweet science!). This thin spit of land is part of the barrier island complex that protects downtown Beaufort (and the Duke Marine Lab!) from storms coming through the rapidly widening Beaufort Inlet. The data collected establish an accurate modern baseline for the west end of the island.
Duke researchers Julian Dale and Everette Newton joined a team of scientists from NOAA and MIT to study the distribution and density of adult gray seals and their pups on Muskeget Island near Nantucket, Massachusetts. Below are two preliminary uncorrected visualizations from the surveys – a 3D mesh model of the terrain and a high-resolution orthomosaic of the entire island.
The surveys were conducted with a senseFly eBee fixed-wing UAS and the images collected were processed with Pix4D software to generate these synthetic products. These data are being used in ongoing studies of the population biology of Western North Atlantic gray seals.
