资源简介:
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 fish using 38, 120, and 200 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 Sayreville, 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)cdom (1e-9)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)...

本项目正在开展一项季节性基线调查,在两年期间的每个季节部署一对滑翔机(gliders),配备全套可用传感器,以同步绘制海洋学和生态学变量图谱。 该滑翔机配备了耦合CTD/pH传感器、WETLabs FLBBCD ECO传感器(配置用于同步叶绿素荧光和光学后向散射测量)、声学浮游动物鱼类剖面仪(Acoustic Zooplankton Fish Profiler, AZFP)多频回声测深仪(用于主动声学探测中上层生物,换能器配置为38、120和200 kHz以探测鱼类),以及Vemco VMT鱼类遥测接收器(用于追踪通过该区域的标记物种)。 此次部署从新泽西州塞尔维尔出发,持续约21至30天,将沿新泽西州海岸的现有及规划海上风电租赁区及其周边执行之字形断面航行,计划在新泽西州塔克顿回收。 实时数据集包含CTD、叶绿素a、有色可溶性有机物(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后进行处理。 cdm_data_type = TrajectoryProfile 变量: azfp文件偏移量(sci_azfp_file_offset,无量纲) azfp暂停信号(sci_azfp_pause_signal,布尔型) azfp运行状态(sci_azfp_run_state,无量纲) 700nm处的β值(117度下的Beta 700nm,单位:m⁻¹ sr⁻¹) 有色可溶性有机物(单位:1e-9) 叶绿素a(单位:kg·m⁻³) 指令高度时间(c_alt_time,单位:秒) 指令压载泵量(c_ballast_pumped,单位:立方厘米) 指令爬升目标深度(c_climb_target_depth,单位:米) 指令下潜目标深度(c_dive_target_depth,单位:米) 指令鳍角(c_fin,单位:弧度) 指令航向(c_heading,单位:弧度) 指令发送所有科学数据(c_science_send_all,布尔型) 指令推进器开启状态(c_thruster_on,单位:%) 指令抛载(c_weight_drop,布尔型) 指令航点纬度(c_wpt_lat,单位:纬度) ...(另有149个变量)
