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 profiling CTD instrument designed specifically for installation on Slocum autonomous gliders. It measures conductivity, temperature and pressure for use in oceanic research, updating ocean models, assessing sensor stability on moored observatories, and leveraging data collection opportunities from operational vehicle missions. It outputs real-time data in decimal S/m, degC and decibars, or raw decimal counts. It is externally powered and continuously pumped, and can operate in both continuous sampling or polled sampling modes. It features an expendable anti-foulant device offering bio-fouling protection, and is supplied with Seasoft V2 Windows software for setup and data processing. The pressure sensor with temperature compensation is available in 4 strain-gauge ranges; 0-100; 100-350; 350-1000; 1000-2000 metres. It measures conductivity from 0-9 S/m at a resolution of 0.00001 S/m, temperature from -5 to +42 degC at a resolution of 0.001 degC, and pressure up to 2000 m (dependant on the range chosen), at a resolution of 0.002 percent of full scale range.";

String summary "Sea Water Ocean Topography (SWOT) is a radar interferometry mission making SSH measurements over a swath 120 km wide. There is a nadir gap of 20 km where the error from interferometry is not meeting science requirement. The mission's calval requirement is to validate the along-track SSH performance in terms of a wavenumber spectrum of the measurement error by comparison to in-situ measurement. The current candidate for the in-situ measurement is an array of gliders along the center of a swath to resolve the dynamic height at wavelengths of 15-150 km. An OSSE study suggests that a station-keeping glider making vertical loop of the upper 500 m of the water column in 2 hours can meet the requirement of providing quasi-synoptic observations of the dynamic height from the glider array for comparison with the SWOT snapshot measurement of SSH from overflight. The primary objective of the Monterey bay experiment is to test the capability of gliders to retrieve the upper ocean dynamic height time series derived from the M1 moo ring covering the upper 300 m of the water column. Another objective is to make simultaneous measurement of the SSH via a GPS buoy and the bottom pressure via a bottom-pressure recorder. These measurements will allow us to derive the steric component of SSH and compare to the hydrographic measurement by the mooring and gliders. The glider was deployed in the Monterey Bay National Marine Sanctuary and will traverse west southwest to a series of moorings arranged from north to south over a distance of KM km. This dataset contains Conductivity, Temperature and Depth (CTD) measurements. The data will be released on the Global Telecommunication System. Delayed mode dataset.";

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.
