Title: NOAA OAP Seasonal pH Glider Groundtruthing

Summary:
This project conducted seasonal glider deployments to investigate carbonate chemistry and monitor ocean acidification in the Mid-Atlantic Bight. Gliders were deployed with an integrated deep rated version of the Ion Sensitive Field Effect Transistor (ISFET)-based pH sensor. The pH sensor unit was complemented with existing glider sensors including a Conductivity, Temperature, Depth (CTD), a WETLabs FLBBCD ECO puck configured for simultaneous chlorophyll fluorescence and optical backscatter measurements, and an Aanderaa Optode for measuring dissolved oxygen. This is the comparison between pH data recorded by gliders and discrete water samples taken at glider deployments and recoveries. Full-resolution glider datasets can be downloaded via the National Centers for Environmental Information (NCEI) Ocean Carbon and Acidification Data System (https://www.ncei.noaa.gov/products/ocean-carbon-acidification-data-system).

Title: pH Glider Carbonate Chemistry Water Sampling

Summary:
For each project, underwater Slocum gliders were deployed with an integrated Conductivity, Temperature, Depth (CTD) and deep rated version of the Ion Sensitive Field Effect Transistor (ISFET)-based pH sensor as well as other sensors. Water samples were taken during deployment and recovery to ground-truth the glider-based pH sensor. Full-resolution quality-controlled glider datasets can be downloaded via the National Centers for Environmental Information (NCEI) Ocean Carbon and Acidification Data System https://www.ncei.noaa.gov/products/ocean-carbon-acidification-data-system.

Title: RMI Zooplankton Sampling for Glider Echosounder Ground-Truthing

Summary:
This project is conducting a seasonal baseline survey with a pair of underwater Slocum gliders deployed in each season with a full complement of available sensors to simultaneously map oceanographic and ecological variables. Zooplankton samples were taken during glider deployments and recoveries. When a zooplankton-configured ASL Acoustic Zooplankton Fish Profiler (AZFP) was on board the glider, these samples were used to ground-truth the glider-based acoustic zooplankton concentration and biomass estimates. Full-resolution quality-controlled glider datasets and associated raw and processed acoustic data are archived at National Centers for Environmental Information (NCEI)'s Water Column Sonar Data repository https://www.ncei.noaa.gov/products/water-column-sonar-data. Full-resolution raw glider datasets that do not contain the acoustic data can be downloaded at https://slocum-data.marine.rutgers.edu/erddap/index.html.
