Rutgers, The State University of New Jersey author Garzio, Lori M. Rutgers, The State University of New Jersey author Rutgers, The State University of New Jersey contributor tableDigital This dataset contains the trajectory profile data from glider ru34 from one seasonal deployment (2023-09-20 to 2023-10-19). This deployment (glider trajectory ru34-20230920T1506) was part of a project to conduct 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 Mid-Atlantic Bight in the spring to the physical breakdown in the fall. This glider deployment is the second of three gap-fill missions this year. This glider was equipped with a coupled CTD/pH sensor, a WETLabs FLBBCD ECO puck configured for simultaneous chlorophyll fluorescence and optical backscatter measurements, an Aanderaa Optode for measuring dissolved oxygen (sensor failed on 2023-10-07), and an Rx-LIVE 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. QA/QC measures have been run according to the IOOS Manual for Real-Time Quality Control of pH Observations and IOOS Manual of Glider Data. Suspect/failed IOOS QC values, and values flagged by a CTD hysteresis test have been removed from this dataset. pH and dissolved oxygen (when applicable) have been adjusted for sensor lag by applying optimal time shifts calculated by glider segment in order to minimize separation between glider down and upcasts as described in Saba et al 2019 https://doi.org/10.3389/fmars.2019.00664 and Wright-Fairbanks et al 2020 https://doi.org/10.1029/2020JC016505.

Accuracy: ±0.05 Precision ±0.001; Detailed sampling and analyzing information: Once the glider is deployed it completes vertical profiles to collect data throughout the water column. The pH sensor (sampling rate 1 Hz) is coupled to a CTD unit (sampling rate 0.5 Hz) on the glider to provide simultaneous measurements of measured reference voltage, salinity, pressure, and temperature. Standardization Technique Description: For the initial calibration, the pressure response function f(P), temperature response constants k2, and conditioning offset k0 are derived in a controlled laboratory. Calibrations for f(P) and k2 are performed in a pressure vessel with a working fluid of 0.01N Hydrochloric acid (HCl). pH sensors undergo oceanographic temperature ranges (5-35°C) and pressure ranges (0-3000 psi) for 1 week. For the k0 calibration, the sensor is conditioned to natural seawater for 3-5 days before k0 is calculated. For each subsequent maintenance calibration the sensor is cleaned, the sensor is re-conditioned to natural seawater and k0 is re-calculated. The pH sensor is factory calibrated by the manufacturer at least once per year.

Accuracy: ±0.05 Precision ±0.001; Detailed sampling and analyzing information: Once the glider is deployed it completes vertical profiles to collect data throughout the water column. The pH sensor (sampling rate 1 Hz) is coupled to a CTD unit (sampling rate 0.5 Hz) on the glider to provide simultaneous measurements of measured reference voltage, salinity, pressure, and temperature. Standardization Technique Description: For the initial calibration, the pressure response function f(P), temperature response constants k2, and conditioning offset k0 are derived in a controlled laboratory. Calibrations for f(P) and k2 are performed in a pressure vessel with a working fluid of 0.01N Hydrochloric acid (HCl). pH sensors undergo oceanographic temperature ranges (5-35°C) and pressure ranges (0-3000 psi) for 1 week. For the k0 calibration, the sensor is conditioned to natural seawater for 3-5 days before k0 is calculated. For each subsequent maintenance calibration the sensor is cleaned, the sensor is re-conditioned to natural seawater and k0 is re-calculated. The pH sensor is factory calibrated by the manufacturer at least once per year.; Method reference: Optimal time shifts applied in order to minimize separation between glider down and upcasts as described in Saba et al 2019 https://doi.org/10.3389/fmars.2019.00664 and Wright-Fairbanks et al 2020 https://doi.org/10.1029/2020JC016505 Parameter or Variable: Time-lag Adjusted pH; Abbreviation: pH; Unit: 1; Observation type: Glider profile trajectory; Measured or calculated: CALCULATED; Calculation method and parameters: Calculated from sensor calibration coefficents, interpolated pressure, interpolated salinity, interpolated temperature, and measured reference voltage shifted by an optimal time shift calculated by glider segment in order to minimize separation between glider down and upcasts.
