SELECTION SUMMARY
도입 판단 요약
Oceanographic data from stationary moorings deployed as part of the New Brunswick Coastal Monitoring Program. This Program is a collaboration between the Department of Agriculture, Aquaculture, and Fisheries (DAAF), the Centre for Marine Applied Research (CMAR), Fisheries and Oceans Canada Gulf Region, and several third party field contractors. Usage Considerations: The Coastal Monitoring Program provides high resolution ocean data from around the coast of New Brunswick. Temperature, dissolved oxygen, salinity, and pH data is collected 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. Sensors are deployed for several months, and data are measured every 10 minutes 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. An automated Gross Range test was applied to the data to identify outlying and unexpected values. These automated flags were reviewed by human experts and modified where necessary. The results are summarized in the “qc_flag” columns of the dataset. Each data point was assigned a flag of “Pass”, “Fail”, or “Suspect/Of Interest” (IOOS, 2020). Observations flagged as “Pass” passed the 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: 1) 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. 2) Sensor drift is not flagged in the datasets. 3) The sensor_depth_at_low_tide_m column 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 data is organized by region (North and South). 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).
