        "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": "The Challenger Glider Mission is a re-creation of the first global scientific ocean survey conducted by the HMS Challenger from 1872-1876. The goals of the mission are to establish a collaborative international network of autonomous underwater glider ports, to assess global ocean model predictive skill while contributing real-time profile data for assimilation in ocean forecast models by operational centers worldwide, and to crowd source student-based ocean research and discovery. This glider is providing dissolved oxygen, temperature, conductivity, salinity, and density profile observations. RU29\u2019s planned mission extends from Dominica, Martinique, St. Lucia, and St. Vincent and the Grenadines areas. Real-time datasets will include CTD data that will be provided to the IOOS Glider DAC and GTS to support ocean and atmospheric weather forecasting. Delayed mode dataset.",
