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).";

String summary "The Predictions of AcousticS with Smart Experimental Networks of GlidERS (PASSENGERS) project is a partnership between universities and the Naval Research Laboratory to improve the capability of data-assimilative ocean models to predict acoustic propagation in dynamic oceanography environments. It includes the deployment of teams of gliders in small (10 km) spatial footprints with integrated passive acoustics focused on mapping the physical and acoustic environment in the dynamic region of the Atlantis II Seamounts.";

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.
