    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.";

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.";

The developers have implemented a low-frequency detection and classification system (LFDCS) on the DMON to identify marine mammal calls from a variety of autonomous platforms, including gliders, profiling floats, and moorings. The LFDCS produces pitch tracks of sounds, which describe changes in the frequency (pitch) of a call over time. While automated software can roughly identify calls, for best results scientists typically examine spectrograms to identify marine mammal calls and pitch tracks are derived from spectrograms.";

Measurement based on the ability of selected substances to act as dynamic fluorescence quenchers. The fluorescent indicator is a special platinum porphyrin complex embedded in a gas permeable foil that is exposed to the surrounding water. In this standard model, a black optical isolation coating protects the complex from sunlight and fluorescent particles in the water. This sensing foil is attached to a window providing optical access for the measuring system from inside a watertight housing. The foil is excited by modulated blue light, and the phase of a returned red light is measured. For improved stability the 4831 optode also performs areference phase reading by use of a red LED that does not produce fluorescence in the foil. This model is fitted with a standard sensing foil. By linearizing and temperature compensating, with an incorporated temperature sensor, the absolute O2 concentration can be determined. Accuracy +/- 1.5% or 2uM; precision +/- 0.2 uM.";

Using tabledap to Request Data and Graphs from Tabular Datasets

tabledap lets you request a data subset, a graph, or a map from a tabular dataset (for example, buoy data), via a specially formed URL. tabledap uses the OPeNDAP (external link) Data Access Protocol (DAP) (external link) and its selection constraints (external link).

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.
