    This project integrated a deep rated version of the Ion Sensitive Field Effect Transistor (ISFET)-based pH sensor, the Deep ISFET pH, into a Slocum Webb G2 glider. 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. This approximately 15 to 30 day deployment near Sandy Hook, NJ, and is running a cross-shelf transect to the shelf break north of Hudson Canyon to sample in Atlantic sea scallop habitat. Then the glider will turn and fly back to shore in a west-southwest direction to cover more sea scallop and Atlantic surfclam habitat with possible recovery targeted for Barneget, NJ. However, if pH data are still stable after 15 days (no increased time lag response due to biofouling), the glider will turn southeast and head back to the shelf break then fly back inshore toward Atlantic City.
