String 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.";

String description "A custom-built version of the QSP-2150 Quantum Scalar Irradiance PAR Sensor, the QSP-2155 is designed for use on Teledyne Webb autonomous underwater vehicles, such as gliders. It is electronically and functionally equivalent to the QSP-2150, developed for multi-parameter logging applications, but its housing is tailored specifically for glider use. It uses a scalar irradiance collector to obtain a uniform directional response over 3.6-pi steradians. A stainless steel encased optical light pipe guides flux from the collector to a filtered silicon photodetector, resulting in a flat quantum response over the PAR spectral region (400-700 nm). The sensor produces a digital ASCII output and uses a Teledyne-Impulse MCBH series connector. It uses a 24-bit analog to digital converter (ADC) operating at frequencies of 4 to up to 250 Hz. It has a stability (dark reading) of < 0.003 microE m-2 sec-1 and operates in waters depths up to 2000 m.";

String description "A conductivity, temperature and pressure sensor designed for use on gliders and autonomous underwater vehicles (AUVs). It can be used to derive salinity, density and sound velocity and is optimised for turbulence measurements and passive acoustic monitoring due to its silent operation (non-pumped). The instrument is available as two configurations; the standard RBR Legato3 has a 2 Hz standard thermistor response; the RBR Legato3 Fast 16 instrument has a 16 Hz fast thermistor response. Additional sensors such as dissolved oxygen, fluorescence, turbidity, and PAR are all supported. The RBR Legato3 is designed to fit into a standard 2 x 7 inch sensor bay, with both wet- and dry-bay models. The RBR Legato3 is depth-rated to 1000m, with a pressure range from 500-1000 db and accuracy of +/- 0.05 percent (full scale). The conductivity accuracy is +/- 0.003 mS/cm. Temperature range is -5 degC to +42 degC (ITS-90) with an accuracy of +/- 0.002 degC (-5 to +35 degC) and +/- 0.004 degC (+35 to +42 degC).";

Data Access Protocol (DAP) and its
selection constraints.
The URL specifies what you want: the dataset, a description of the graph or the subset of the data, and the file type for the response.
Tabledap request URLs must be in the form
https://coastwatch.pfeg.noaa.gov/erddap/tabledap/datasetID.fileType{?query}
For example,
https://coastwatch.pfeg.noaa.gov/erddap/tabledap/pmelTaoDySst.htmlTable?longitude,latitude,time,station,wmo_platform_code,T_25&time>=2015-05-23T12:00:00Z&time<=2015-05-31T12:00:00Z
Thus, the query is often a comma-separated list of desired variable names,
followed by a collection of
constraints (e.g., variable<value),
each preceded by '&' (which is interpreted as "AND").
For details, see the tabledap Documentation.
