Through the Water Quality Branch of the program, CMAR collects temperature, dissolved oxygen, and salinity data using sensors deployed on stationary moorings. A typical mooring consists of a line anchored to the sea floor and suspended by a sub-surface buoy, with sensors attached at various depths. Alternatively, sensors may be attached to structures including buoys, docks, or aquaculture equipment. Sensors are deployed for several months, and data are measured every 1 minute to 1 hour. Station locations, summary reports, and data collection methods are available on the CMAR website (https://cmar.ca/coastal-monitoring-program/). Datasets and reports may be revised pending ongoing data collection and analyses. Automated Quality Control tests were 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. Observations flagged as “Pass” passed all tests, while observations flagged as “Fail” failed at least one test and should be excluded from most analyses. “Suspect/Of Interest” flags highlight unusual events or poor quality data, and “Not Evaluated” flags indicate at least one test was not applied to the observation. Flags should be used as a guide only, and users are responsible for evaluating the data quality prior to use. For technical details on the Quality Control tests, visit the CMAR Data Governance website (https://dempsey-cmar.github.io/cmp-data-governance/pages/cmp_about.html). Other data quality considerations: - Through calibration-validation procedures, CMAR has discovered that the VR2AR temperature sensors typically record 0.5 – 1 °C lower than other temperature sensors. This is not corrected for or flagged in the datasets but may be in the future. - Sensor drift is not flagged in the datasets. - The sensor_depth_at_low_tide_m is an estimate and should be compared to sensor_depth_measured_m when possible. Note the mooring can get “knocked down” by currents or sink from biofouling. Large discrepancies between the estimated depth and the minimum recorded depth are flagged in the column depth_crosscheck_flag. 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. Take care when exporting data filtered on quality control columns, because the whole row will be filtered (i.e., all other variables measured at that timestamp will also be excluded).

The program was initiated by the Nova Scotia Department of Fisheries and Aquaculture (NSDFA) in 2015. In 2019, CMAR assumed responsibility for the program and expanded its scope and mandate. Through the Wave Branch of the program, CMAR processes and publishes Wave data collected by NSDFA. The data are measured by upward facing Acoustic Doppler Current Profilers (ADCPs) that are mounted on the sea floor for 1 - 3 months. An ADCP uses sound to measure wave variables including height, period, and direction. NSDFA uses several ADCP instrument models, including the Sentinel V20, Sentinel V50, Sentinel V100, and Workhorse Sentinel 600kHz. The data is processed using Velocity and WavesMon4 Software, and then compiled and formatted for publication with CMAR’s waves R package. An automated “Gross Range” test was applied to the data to identify statistical outliers. Each data point was assigned a flag value of “Pass”, “Suspect/Of Interest”, or “Fail”. Observations flagged as “Pass” passed the test (i.e., were not considered outliers) and can be included in analyses. Observations flagged as “Fail” were considered outliers and should be excluded from most analyses. Observations flagged as “Suspect/Of Interest” were either poor quality or highlight an unusual event, and should be carefully reviewed before being 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. The \"Nova Scotia Current and Wave Data: Deployment Information\" dataset on this Portal shows all locations with available Wave data collected through CMAR’s Coastal Monitoring Program (https://data.novascotia.ca/Fishing-and-Aquaculture/Nova-Scotia-Current-and-Wave-Data-Deployment-Infor/uban-q9i2/about_data). Summary reports for each county are available on the CMAR website (https://cmar.ca/coastal-monitoring-program/). Data collection and retrieval are ongoing. The datasets and reports may be revised pending ongoing data collection and analyses.
