2010-11-11T00:00:00Z Recovered S. of Oahu by OTG Safe boat: nearing end of battery life, deployed: 107 days.
2022-11-17T23:30:00Z Dataset identifier modified from \"sg139_8\" to \"sg_139_008\" to better match PacIOOS naming conventions.
2023-02-07T18:35:00Z Renamed \"depth\" variable to \"altitude\" per the ERDDAP convention for negative ocean depths (positive=up). Added \"dive_number\" variable.

Additionally, these data get used in computer models to make predictions about currents. Ocean gliders are small, free-swimming, unmanned vehicles that can cruise the ocean for several months gathering information about the temperature, salinity, and other water properties between the surface and 1000 m depth. A pressure sensor on the glider is able to record the depth throughout the dive. Because gliders are unmanned, they communicate with scientists on land when they are at the surface using an antenna on the end of the glider. The SeaGlider autonomous underwater vehicle (AUV) was designed at the University of Washington (UW) Applied Physics Laboratory (APL). These data are taken from Mission 8 of SeaGlider 139.";

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.
