        "description": "A long-range autonomous underwater vehicle (AUV) based on buoyancy. It 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 54 kgs. 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 600-6000 km, a deployment length of 15 days to 12 months and an operating depth range of 4-1000m. Navigation is via GPS waypoints, a pressure and altimeter sensor. Maximum speed is .35 m/s. It transmits via RF modem, Iridium (RUDICS), ARGOS or acoustic modem.",

        "summary": "This project supports the deployment and real-time data delivery of autonomous underwater gliders in the coastal ocean to better resolve and understand essential ocean features and processes that contribute to hurricane intensification or weakening prior to making landfall. This includes a partnership between the Integrated Ocean Observing System (IOOS) regional associations such as MARACOOS, SECOORA, CariCOOS and institutions including the University of Puerto Rico, University of the Virgin Islands, Skidaway Institute of Oceanography, University of Delaware, and Rutgers University. The goal of the project is to provide real-time data for ocean model validation and assimilation throughout hurricane season. This project is supported by the Disaster Recovery Act. This glider will sample a triangle pattern from the mouth of the Delaware Bay out toward the shelf-break and will additionally be used to collect geolocation data to train an animal tag geolocation algorithm.",
