IOOS Glider - Orsted Cod Monitoring - ru34-20250311T1220-delayed

This project is using a JASCO OceanObserver hydrophone attached to a glider to monitor and understand the spatial and temporal distribution of spawning cod aggregations in the Revolution Wind and Sunrise Wind offshore wind lease areas during the spawning season. These glider-based observations are occurring during construction activities that may include seabed preparation along cable routes and placement of scour protection at the foundation locations. The glider is also equipped with a CTD, a WETLabs FLBBCD ECO puck configured for simultaneous chlorophyll fluorescence and optical backscatter measurements, an Aanderaa optode for measuring dissolved oxygen, and a VEMCO receiver. This is the fifth sequential deployment planned to monitor the wind lease area for five months during cod spawning season, November through March.

本项目采用搭载于水下滑翔机（glider）的JASCO OceanObserver水听器（hydrophone），在产卵季节监测并解析Revolution Wind与Sunrise Wind海上风电租赁区内产卵鳕鱼群聚的时空分布特征。这些基于滑翔机的观测同步于施工活动开展，后者可能包括电缆路径的海床预处理及基础位置的防冲刷保护铺设。该滑翔机还配备了温盐深仪（CTD）、可同步测量叶绿素荧光与光学后向散射的WETLabs FLBBCD ECO传感器探头、用于测定溶解氧的Aanderaa光学溶解氧传感器（optode）及VEMCO接收器。本次部署为第五次连续任务，计划于11月至次年3月的鳕鱼产卵季期间对风电租赁区开展为期五个月的监测。延迟模式数据集的cdm_data_type为TrajectoryProfile。变量包括：beta_700nm（117度下的700nm散射系数，单位：m⁻¹·sr⁻¹）、beta_700nm_reference（117度下的700nm参考散射系数，单位：m⁻¹·sr⁻¹）、beta_700nm_signal（117度下的700nm散射信号，单位：m⁻¹·sr⁻¹）、cdom（有色溶解有机物，单位：1e-9）、cdom_reference（CDOM参考信号，无量纲）、cdom_signal（无量纲）、chlorophyll_a（叶绿素a，单位：kg·m⁻³）、chlorophyll_a_qartod_gross_range_test（QARTOD粗范围测试质量标志）、chlorophyll_a_qartod_summary_flag（QARTOD汇总质量标志）、chlorophyll_a_reference（无量纲）、chlorophyll_a_signal（无量纲）、commanded_fin（指令鳍角，单位：弧度）、commanded_heading（指令航向，单位：弧度）、commanded_obsvr_num_fields_to_send（指令观测器待发送字段数，无量纲）、commanded_obsvr_on（指令观测器开启时间，单位：秒）、commanded_pitch（指令俯仰角，单位：弧度）、commanded_roll（指令滚转角，单位：弧度）、commanded_wpt_lat（指令航点纬度，单位：纬度）、commanded_wpt_lon（指令航点经度，单位：经度）...（另有134个变量）
