attribute	NC_GLOBAL	processing_level	String	Delayed mode data. Salinity, Density, pH, TA, and Aragonite have been calculated from raw variables. 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 (QC code: https://github.com/rucool/rugliderqc). CTD variables have been adjusted for thermal lag. pH and dissolved oxygen (DO not available in this dataset) variables 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.

attribute	NC_GLOBAL	summary	String	This project is conducting seasonal deployments to investigate carbonate chemistry and monitor ocean acidification in the Mid-Atlantic Bight. The glider used for the automated observation includes an integrated deep rated version of the Ion Sensitive Field Effect Transistor (ISFET)-based pH sensor. The pH sensor unit is complemented with existing glider sensors including a CTD, a WETLabs FLBBCD ECO puck configured for simultaneous chlorophyll fluorescence and optical backscatter measurements, and an Aanderaa Optode for measuring dissolved oxygen. Please note the oxygen sensor failed so dissolved oxygen measurements are not included in this dataset. This approximately 21 to 30 day deployment out of Tuckerton, NJ will run a cross-shelf transect (along E line) to an offshore waypoint north of Carteret Canyon, then transect SSW to Wilmington Canyon, then NW back to Tuckerton, NJ as the battery pack allows. This glider track will cover Atlantic sea scallop and Atlantic surfclam habitats in the southern MAB. The real-time dataset contains CTD, dissolved oxygen (sensor failed), chlorophyll a, CDOM and optical backscatter measurements. pH data will be processed post-deployment. This is the third deployment of this glider in 2021. Delayed mode dataset.
