Underwater and topside imagery, videos, and biological characterization data collected during the Peleliu's Forgotten WWII Battlefield 2018 Expedition in the South Pacific Ocean from 2018-03-25 to 2018-04-14 (NCEI Accession 0247575)

This data set contains archaeological project images and videos obtained using the following equipment: Olympus Tough TG-5; DJI Mavic Pro Platinum drone; Olympus PEN Lite E-PL5 camera with Olympus PT-EP10 underwater housing; GoPro Hero 4; Nikon D700 Digital Camera. Swimmer/diver reconnaissance took place in the shallow areas of the reef not navigable by boat and a walking survey of the invasion beaches from the shoreline to approximately 30 meters inland was conducted. Standard archaeological documentation included photographs and written documentation of significant features.

The purpose of this project was to locate the scattered material remains of Peleliu’s submerged battlefield, to photogrammetrically record those remains, and to examine the reef substrate and its coral communities to determine if the scars from the UDT 2 mission to blow access ramps into the lagoon were still visible after 74 years.
