String summary "The Centre for Marine Applied Research’s (CMAR) Coastal Monitoring Program provides high resolution data on ocean variables from around the coast of Nova Scotia. The program was initiated by the Nova Scotia Department of Fisheries and Aquaculture in the early 1990s. In 2019, CMAR assumed responsibility for the program and expanded its scope and mandate. Through the Water Quality Branch of the program, CMAR collects temperature, dissolved oxygen, and salinity data using sensors deployed on “sensor strings”. A sensor string typically consists of a line anchored to the sea floor by an acoustic release and suspended by a sub-surface buoy, with sensors attached at various depths below the surface (as measured at low tide). Alternatively, a string may be attached to surface moorings, including floating docks, buoys, and equipment. Sensor strings are deployed for several months, and data are measured every 1 minute to 1 hour. Sensors are retrieved for data offload by triggering the acoustic release when applicable, by directly removing from surface moorings, or occasionally by divers or grappling methods. Automated Quality Control tests have been applied to the data to identify outlying and unexpected observations. The results of these tests are summarized in the “qc_flag” columns of the dataset. Each data point is assigned a flag value of “Pass”, “Suspect/Of Interest”, “Fail”, or “Not Evaluated”. Observations flagged as “Pass” passed all tests and can be included in analyses. Dissolved oxygen observations flagged as “Suspect/Of Interest” likely indicate biofouling signals and should be excluded from analysis or used with extreme caution. Observations for other variables flagged as “Suspect/Of Interest” should be reviewed before being included in analyses. Observations flagged as “Fail” should be excluded from most analyses. Some tests cannot be applied to certain observations, which will be flagged as “Not Evaluated”. These observations can typically be included in analyses. Flags should be used as a guide only, and data users are responsible for evaluating the quality of the data prior to use in any analysis. For more information about the Quality Control tests, visit the CMAR Data Governance website (https://dempsey-cmar.github.io/cmp-data-governance/pages/cmp_about.html). The Coastal Monitoring Program Water Quality data is organized by county. These datasets are very large, typically exceeding the number of rows that can be viewed in Excel. CMAR recommends filtering the data to the waterbody, station, depth, quality control flag, and/or time period of interest before exporting. A chart derived from the dataset also allows for interactive filtering and export https://data.novascotia.ca/d/yeii-vbir). The \"Nova Scotia Water Quality Data: Station Locations\" dataset on this Portal shows additional locations with available Water Quality data collected through CMAR’s Coastal Monitoring Program (https://data.novascotia.ca/Nature-and-Environment/Coastal-Monitoring-Program-Station-Locations/cjfb-f4d4). Summary reports by county are available on the CMAR website (https://cmar.ca/coastal-monitoring-program/). Data can also be downloaded from the ERDDAP server through the Canadian Integrated Ocean Observing System (CIOOS) platform (https://catalogue.cioosatlantic.ca/dataset?q=cmar). Data collection and retrieval are ongoing. The datasets and reports may be revised pending ongoing data collection and analyses. If you have accessed any Coastal Monitoring Program data, CMAR would appreciate your feedback: https://docs.google.com/forms/d/e/1FAIpQLSe3TD6umrsVVKnQL13VVMJIpckCi2ctONJsgN7_g-4c-tKTuw/viewform.

contraintes de sélection .
L'URL spécifie ce que vous voulez : l'ensemble de données, une description du graphique ou du sous-ensemble des données et le type de fichier pour la réponse.
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.
