Benthic cover derived from structure from motion images collected during marine debris surveys at coral reef sites entangled with derelict fishing nets at Pearl and Hermes Atoll in the Northwestern Hawaiian Islands from missions in 2018 and 2021

The benthic cover and fishing-net related data described in this dataset are derived from the GIS analysis of benthic orthophotos. The source imagery was collected by snorkelers using a Structure from Motion (SfM) approach during swim surveys in search of derelict fishing nets. Surveys were conducted by the NOAA Fisheries, Ecosystem Sciences Division (ESD) at Pearl and Hermes Atoll in the North...

本数据集所述的底栖覆盖面积及与渔网相关的数据，源自对底栖正射影像图的地理信息系统分析。源图像由潜水员采用运动结构化（SfM）方法，在搜寻废弃渔网的游泳调查中采集。调查由美国国家海洋与大气管理局（NOAA）渔业生态系统科学分部（ESD）在北部的珍珠与赫尔默斯环礁进行。
