RELEASE-2022

A dual beam echosounder with side scan sonar and WAAS GPS are used to collect bathymetric (depth) and backscatter (signal strength) data. These data are collected using a boat-mounted system applied during surveys of NEON lakes and river sites. Bathymetric surveys are completed every 5 years; if an extreme event results in substantial changes to the physical environment then an out-of-cycle survey may be conducted. Depth data are used to produce bathymetric maps and side scan sonar data are used to classify subaquatic features to produce a habitat map. Instrumentation: Humminbird 1198c Si Combo

本数据集采用搭载侧扫声呐的双波束回声测深仪与广域增强GPS（WAAS GPS），采集水深测量（水深值）与后向散射（信号强度）两类数据。此类数据通过船载系统采集，应用于NEON（国家生态观测站网络，National Ecological Observatory Network）的湖泊与河流点位调查项目。水深测量每5年开展一次；若极端事件导致物理环境发生显著变化，则可开展周期外的补充调查。水深数据可用于生成水深地形图，侧扫声呐数据则用于分类水下地貌特征以生成生境地图。仪器配置：Humminbird 1198c Si Combo
