        "summary": "Next leg of the ru29 Challenger mission from Brazil to South Africa.  The Challenger Mission is a re-creation of the first global scientific ocean survey conducted by the HMS Challenger in 1872.  A fleet of up to 16 autonomous underwater gliders will be deployed in all five ocean basins.  The goals of the project are the spread ocean literacy, educate the general population about the ocean's impact on global climate and provide real-time temperature, salinity and density profiles for assimilation into regional and global weather forecasting models. This is the high-resolution delayed mode data set containing CTD profiles. The glider was deployed 100 nautical miles offshore of Santos, Brazil and transected to the shelf break before being recovered..",

        "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.",
