Surveys were conducted by the NOAA Fisheries, Ecosystem Sciences Division (ESD) at Pearl and Hermes Atoll in the Northwestern Hawaiian Islands (NWHI). The photographs in this collection are from follow-up surveys that occurred from September 13-14, 2021 on a joint mission with non-profit organization Papahānaumokuākea Marine Debris Project aboard the M/V IMUA, to assess reef recovery. Impact images are those taken from sites which were previously entangled with nets, and control images were either relocated or newly established to fulfill the paired study design. The 2021 mission attempted to relocate all paired sites where "after" and "control" photos were taken in 2018; if found, the permanent 3 x 3m plot was reimaged using the same SfM approach. Only a subset of 2018 sites were successfully relocated in 2021 (12 "after" sites, 8 "control" sites), and five new nearby "control" sites had to be established to fulfill the paired study design. The Papahānaumokuākea Marine National Monument (PMNM) includes the 1200 nautical mile chain of atolls and islets known as the Northwestern Hawaiian Islands (NWHI) that are geographically positioned as a repository for marine debris. Marine debris circulates within the North Pacific Subtropical Gyre until it encounters the atolls of the NWHI. The Ecosystem Sciences Division (ESD) at NOAA Fisheries has conducted both ship- and shore-based missions in the NWHI to survey for and remove derelict fishing gear and many other types of marine debris. Exploratory and opportunistic efforts began in 1996 that evolved into ~annual cruises. The collected photographs were processed using a structure from motion (SfM) approach to create orthophotos and analyzed in GIS for benthic cover. The purpose of the Structure from Motion (SfM) surveys at Pearl and Hermes Atoll is to understand whether derelict fishing nets significantly alter the benthic community composition of the reef and how these impacts last over time once the net is removed. This study leveraged SfM, an emerging photogrammetry technique, to allow efficient data collection alongside marine debris survey and removal efforts.
