        "description": "A long-range autonomous underwater vehicle (AUV) based on buoyancy. The G3S utilises the same features as the G3 glider but uses a new STM32 Processor. This replaces the Persistor processor used on the G3 glider in the Science and Flight Bays. The G3S is used for remote water column sampling. It uses hydraulic buoyancy change to alter the vehicle density in relation to the surrounding water thereby causing the vehicle to either float or sink. Given an appropriate dive or climb angle, the wings and body lift and convert some of this vertical motion into a forward saw tooth horizontal motion. Periodically, the glider surfaces and calls via Iridium Satellite Phone (anywhere in world) or Free Wave RF Modem (line of sight) in to Dockserver (auto attendant computer) to relay navigational fix, data and receive further instructions for command and control. The glider is capable of storm sampling and can be flown in a coordinated fleet. It is 1.5 m in length, has a hull diameter of 22 cm and mass of 55-70 kgs (dependent upon configuration). It has an exchangeable payload (capacity up to 6 L) which is capable of housing a variety of environmental sensors such as nitrate and oxygen. It uses lithium or alkaline batteries. It has a deployment range of 350-13000 km (dependent upon configuration), a deployment length of 15 days to 18 months (dependent upon configuration) and an operating depth range of 4-1000m. Navigation is via GPS waypoints, a pressure and altimeter sensor. Maximum speed is 0.35 m/s (0.68 knot) with the buoyancy engine and an average up to 0.5 m/s (1 knots) with full drive. The thruster provides speeds up to 1 m/s (2 knots). It transmits via RF modem, Iridium (RUDICS), ARGOS or acoustic modem. The new STM32L4 CPU processor utilises OpenRTOS running up to 120 MHz, with 8 Mbytes RAM and 32 Mbytes of flash memory.",

        "summary": "This glider deployment will profile along a mission track between the Leading Light Wind (LLW) lease area and the shelf break in order to sample oceanographic variables and monitor North Atlantic right whale (NARW) presence in the area. The glider will be equipped with a CTD to determine water depth, temperature, salinity, and density, an optics puck measuring chlorophyll-a and colored dissolved organic matter (CDOM) fluorescence, an Optode measuring dissolved oxygen, and a DMON passive acoustics sensor for marine mammal monitoring and detection. The glider will also carry a fish telemetry receiver (Vemco) to track tagged species moving through the region. The sensor suite on the glider will simultaneously characterize the ecosystem's physical structure (Temperature, Salinity, Density; Seabird CTD), tagged fish presence (Vemco receiver), and marine mammal presence (passive acoustics; DMON). The glider will sample these variables at a vertical resolution of 0.25 m and a horizontal resolution of a vertical profile approximately every 100 m along the path. This will fill a sampling gap in NARW surveys in the offshore region of the Mid Atlantic Bight during the season they are most frequently observed in the region. Select marine mammal detections, including NARW, will be available in near-real-time on http://robots4whales.whoi.edu/, and tag detections will be shared to the Atlantic Cooperative Telemetry Network MATOS database after recovery of the glider.
