The PacIOOS Water Quality Sensor Partnership Program (WQSPP) supports scientists and natural resource managers to collect water quality data in order to inform research, conservation, planning, and resource management projects in the U.S. Insular Pacific region. Comprised of a network of \"roving\" water quality nearshore sensors, the WQSPP provides participating partners with sensors, data management, and technical capacity-building to allow for robust data collection. As part of the WQSPP, the Maui Nui Marine Resource Council (MNMRC) deployed a nearshore sensor at Maalaea Harbor, Maui. The non-profit organization is interested to learn more about the effects of tides, wind, and swell on water quality in the harbor, and monitor water quality variability over time. The data will help inform the watershed management plan \"Vision for Pohakea\", which aims to reduce sediment and pollutants in Maalaea Bay and its harbor. MNMRC is also partnering with Waterkeepers Hawaiian Islands to utilize several thousand oysters in the harbor to help improve water quality. Rotating at approximately monthly intervals to various locations within the harbor, the instrument is a Sea-Bird Scientific SBE 16plus V2 SeaCAT CTD coupled with a Sea-Bird Scientific ECO FLNTU optical sensor.";

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.
