Benthic Surveys in Vatia, American Samoa: benthic cover derived from analysis of benthic images collected during belt transect surveys of coral demography from 2020-01-23 to 2020-01-29 (NCEI Accession 0264809)

The benthic cover data described here were generated from the quantitative analysis of photoquadrat benthic images using CoralNet image analysis software, whereby random points are projected on each image and the benthic elements falling directly underneath each point are identified. The images were collected at 18 stratified randomly selected sites in Vatia Bay in 2015 during belt transect surveys of coral demography by the Ecosystem Sciences Division (ESD) of the NOAA Pacific Islands Fisheries Science Center (PIFSC).

The benthic cover data can be accessed online via the NOAA National Centers for Environmental Information (NCEI) Ocean Archive. The benthic images and coral demography data are described and archived separately.

本数据集所述的底栖覆盖率数据系通过珊瑚网图像分析软件对底栖图像进行定量分析所得，该软件于每幅图像上随机投射点，并识别每个点下方的底栖元素。这些图像于2015年收集于瓦蒂亚湾18个分层随机选取的地点，当时由美国国家海洋和大气管理局太平洋岛屿渔业科学中心（PIFSC）生态系统科学部（ESD）进行的珊瑚种群 belt transect 调查期间。底栖覆盖率数据可通过美国国家海洋和大气管理局国家环境信息中心（NCEI）海洋档案在线获取。底栖图像和珊瑚种群数据分别进行了描述和归档。
