IOOS Glider - RMI Eco-gliders - ru40-20230629T1430

This project is conducting a 2-year baseline survey with a pair of gliders deployed in each season, and a 3rd glider deployed three times per year to fill coverage gaps in the seasonal glider deployments from the onset of seasonal stratification associated with the Cold Pool formation in the spring to the physical breakdown in the fall. This glider deployment is the first of three gap-fill missions this year. The gliders are integrated with a full complement of available sensors to simultaneously map oceanographic and ecological variables. This glider is 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, a DMON passive acoustic sensor for the detection of marine mammals, and an Rx-LIVE fish telemetry receiver to track tagged species moving through the region. This approximately 21- to 30-day deployment out of Sandy Hook, 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 dissolved oxygen measurements. The display of baleen whale occurrence information will be available in near real-time on the Robots4Whales website (http://robots4whales.whoi.edu). Vemco acoustically-derived data will be processed post-deployment.cdm_data_type = TrajectoryProfileVARIABLES: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)...

本项目正在开展一项为期2年的基线调查，每个季节部署一对水下滑翔机（glider），并每年部署3次第三台水下滑翔机，以填补季节性层化期间的部署覆盖空白——该时段从春季冷水团（Cold Pool）形成引发季节性层化开始，直至秋季物理层化消散结束。本次水下滑翔机部署为今年三项填补空白任务中的首次任务。
该水下滑翔机集成了全套可用传感器，可同步测绘海洋学与生态学变量。其搭载的设备包括：CTD、配置为同步测量叶绿素荧光与光学后向散射的WETLabs FLBBCD ECO 探头（WETLabs FLBBCD ECO puck）、用于测量溶解氧的Aanderaa Optode、用于检测海洋哺乳动物的DMON被动声学传感器，以及用于追踪该区域内标记物种移动的Rx-LIVE鱼类遥测接收器。
本次部署从新泽西州桑迪胡克（Sandy Hook）启航，作业时长约21至30天，将沿新泽西海岸、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，计划回收地点为新泽西州塔克顿（Tuckerton）。
实时数据集包含CTD、叶绿素a、有色可溶性有机物（CDOM）、光学后向散射及溶解氧测量数据。须鲸出现信息的近实时展示可通过Robots4Whales网站（http://robots4whales.whoi.edu）获取。Vemco声学衍生数据将在部署后进行处理。
