IOOS Glider - RMI Eco-gliders - ru40-20260227T1605

This project is conducting a seasonal baseline survey with a pair of gliders deployed in each season over two years with a full complement of available sensors to simultaneously map oceanographic and ecological variables. This glider is equipped with a coupled CTD/pH sensor, a WETLabs FLBBCD ECO puck configured for simultaneous chlorophyll fluorescence and optical backscatter measurements, an Acoustic Zooplankton Fish Profiler (AZFP) multi-frequency echo sounder for active acoustic detection of pelagic organisms (transducers configured for zooplankton using 120, 200, 455 and 769 kHz), and a Vemco VMT fish telemetry receiver to track tagged species moving through the region. This approximately 21- to 30-day deployment out of Manasquan, New Jersey will run a zig-zag transect along the coast of New Jersey, in and around current and planned offshore wind lease areas, with a planned recovery out of Tuckerton, New Jersey. The real-time dataset contains CTD, chlorophyll a, CDOM, optical backscatter, and pH measurements. Acoustically-derived data will be processed post-deployment.cdm_data_type = TrajectoryProfileVARIABLES:azfp_file_offset (sci_azfp_file_offset, nodim)azfp_pause_signal (sci_azfp_pause_signal, bool)azfp_run_state (sci_azfp_run_state, nodim)beta_700nm (Beta 700nm at 117 degrees, m-1 sr-1)chlorophyll_a (kg.m-3)commanded_alt_time (c_alt_time, sec)commanded_ballast_pumped (c_ballast_pumped, cc)commanded_climb_target_depth (c_climb_target_depth, m)commanded_dive_target_depth (c_dive_target_depth, m)commanded_fin (c_fin, rad)commanded_heading (c_heading, rad)commanded_science_send_all (c_science_send_all, bool)commanded_thruster_on (c_thruster_on, %)commanded_weight_drop (c_weight_drop, bool)commanded_wpt_lat (c_wpt_lat, lat)commanded_wpt_lon (c_wpt_lon, lon)...

本项目将开展为期两年的季节性基线调查，每个季节均部署一对滑翔机，搭载全套可用传感器，同步测绘海洋学与生态学变量。本次部署的滑翔机搭载了耦合式温盐深/ pH（Conductivity Temperature Depth/CTD/pH）传感器、配置为同步测量叶绿素荧光与光学后向散射的WETLabs FLBBCD ECO探测探头、用于主动声学探测中上层生物的多频回声测深仪——声学浮游生物鱼群剖面仪（Acoustic Zooplankton Fish Profiler, AZFP），其换能器采用120、200、455及769 kHz频段以适配浮游生物探测，同时搭载Vemco VMT鱼类遥测接收机，用于追踪该区域内的标记物种移动轨迹。本次部署自新泽西州马纳斯昆港（Manasquan）出发，时长约21至30天，将沿新泽西海岸在当前及规划中的海上风电租赁区域内外开展锯齿状断面巡航，计划于新泽西州塔克顿港（Tuckerton）回收滑翔机。实时数据集包含CTD、叶绿素a、有色溶解有机物（Colored Dissolved Organic Matter, CDOM）、光学后向散射及pH测量数据。声学衍生数据将在部署完成后进行后期处理。
