Digby County Water Quality Data

The Centre for Marine Applied Research (CMAR) measures environmental data throughout Nova Scotia’s coastal waters as part of the Coastal Monitoring Program. This program was initiated by the Nova Scotia Department of Fisheries and Aquaculture in 2012 and CMAR became involved in 2017. CMAR collects temperature (degrees Celsius), dissolved oxygen (% saturation), and intermittent salinity (practical salinity units) data using autonomous sensors attached to moored lines, called ‘sensor strings’. Each string is attached to the seafloor by an anchored acoustic release and suspended by a sub-surface buoy, with sensors attached at various depths. Sensor strings are typically deployed for several months, and data are measured every 1 minute to 1 hour depending on the sensor. Data are retrieved by triggering the acoustic release, enabling the sensor string to float to the surface for data download. Some data are excluded from the final dataset during quality control processes. The Coastal Monitoring Program data is organized by county. These datasets are very large, typically exceeding the number of rows that can be viewed in Excel. We recommend using the filter options of the Open Data Portal to filter to the WATERBODY, STATION, DEPTH, VARIABLE, and/or TIMESTAMP of interest before exporting. A chart derived from the dataset also allows for interactive filtering and export (https://data.novascotia.ca/Nature-and-Environment/Coastal-Monitoring-Program-Data-Digby-County-Daily/yeii-vbir). Coastal Monitoring Program data for other Nova Scotia counties is also available through the Open Data Portal. The ''Coastal Monitoring Program: Station Locations'' dataset on the Portal shows locations with available data (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/2020/07/14/coastal-monitoring-program/). Data collection and retrieval are ongoing. The datasets and reports may be revised pending ongoing data collection and analyses.Contains information licensed under the Open Government Licence – Nova Scotia.
