It provides real-time oceanographic observations from a depth of about 4,800 m via a submarine fiber optic cable that comes ashore at Makaha on Oahu. This data set provides measurements of ocean current velocity at the ACO from a 250 kHz SonTek acoustic doppler current profiler (ADCP) at 1.83 m above the ocean bottom. Velocities are flagged bad if the amplitude is excessively low or high. An amplitude is high if it exceeds the average of the ping before and the ping after by 20 counts. An amplitude is low if less than 6 counts. After this the velocities are flagged bad if the absolute deviation of the vertical velocity from its ensemble median exceeds 0.15 m/s or if its value is less than -0.25 m/s.";

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://upwell.pfeg.noaa.gov/erddap/tabledap/datasetID.fileType{?query}
For example,
https://upwell.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.
