Sitka Tribe of Alaska’s Environmental Research Laboratory adjacent to Sitka Harbor, has been a site for shore-based and high-resolution measurement of surface seawater CO2 content since June 2017. Temperature, salinity, and CO2 partial pressure measurements are made near-continuously from a seawater sample line with an intake 50 m from shore and at a depth of 1 m in Sitka Harbor. The effort to collect these data is a collaboration between the Sitka Tribe of Alaska and the Hakai Institute with support from the Alaska Ocean Observing System."; String time_coverage_end "2021-04-27T09:55:00Z"; String time_coverage_start "2017-06-01T10:07:00Z"; String title "High-resolution record of surface seawater carbon dioxide (CO2) content, water temperature, sea surface salinity and other parameters collected in Sitka Harbor, Alaska, USA"; Float64 Westernmost_Easting -135.3456; } }
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.
