Trajectory profile data from glider ru39, including pH, Total Alkalinity, and Aragonite Saturation State, deployed by Rutgers, the State University of New Jersey in the Mid-Atlantic Bight from 2024-10-21 to 2024-11-19 (NCEI Accession 0306285)

This dataset contains the trajectory profile data from glider ru39 from one seasonal deployment (2024-10-21 to 2024-11-19). This deployment (glider trajectory ru39-20241021T1717) was part of a project to conduct 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 was equipped with a coupled CTD/pH sensor, a WETLabs FLBBCD ECO puck configured for 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 deployment out of Sandy Hook, New Jersey ran a zig-zag transect along the coast of New Jersey, in and around current and planned offshore wind lease areas, and ended near Tuckerton, New Jersey. This delayed mode, high-resolution dataset contains CTD and chlorophyll a measurements, as well as pH, total alkalinity, and aragonite saturation state. Salinity, density, pH, TA, and aragonite saturation state have been calculated from raw variables. Acoustically-derived data are processed separately and not included in this package.

This glider was paired with glider deployment ru40-20241021T1654 which can be downloaded at https://slocum-data.marine.rutgers.edu/erddap/index.html

本数据集包含海洋滑翔机（glider）ru39在单次季节性部署（2024年10月21日至2024年11月19日）期间的轨迹剖面数据。本次部署（滑翔机轨迹编号ru39-20241021T1717）属于一项季节性基线调查项目：该项目计划在两年内的每个季节部署一对滑翔机，搭载全套可用传感器，同步绘制海洋学与生态学变量的空间分布图谱。该滑翔机搭载了集成温盐深（CTD）与pH的耦合传感器、WETLabs品牌FLBBCD ECO探头（配置用于叶绿素荧光与光学后向散射测量）、声学浮游生物与鱼类剖面仪（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，其换能器针对鱼类配置为38、120及200 kHz频段；同时搭载Vemco VMT鱼类遥测接收机，用于追踪该区域内被标记的移动物种。本次部署从新泽西州桑迪角（Sandy Hook）起航，沿新泽西海岸在当前及规划中的海上风电租赁区域内外布设锯齿状断面测线，最终在新泽西州塔克顿（Tuckerton）附近结束任务。本延迟模式（delayed mode）高分辨率数据集包含温盐深、叶绿素a测量数据，以及pH、总碱度（total alkalinity, TA）与文石饱和度状态（aragonite saturation state）数据。盐度、密度、pH、总碱度及文石饱和度状态均由原始观测变量计算得到。声学衍生数据需单独进行后处理，未包含在本数据包内。数据集贡献者包括：Grace Saba、Josh Kohut、Nicole Waite、David Aragon、Brian Buckingham、Kaycee Coleman、Chip Haldeman、John Kerfoot、Laura Nazzaro、Lori Garzio。本滑翔机的配对部署任务为ru40-20241021T1654，相关数据可通过https://slocum-data.marine.rutgers.edu/erddap/index.html下载获取。
