    String 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.";

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.";

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 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.

• (easy) You can get data by using the dataset's Data Access Form or Subset form. They make the URL for you.
• (easy) You can make a graph or map by using the dataset's Make A Graph form. It makes the URL for you.
• (not hard) You can bypass the forms and get the data or make a graph or map by generating the URL by hand or with a computer program or script.

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.
