Current speed and direction time series data collected in a vertical profile at various locations throughout the coastal waters of Richmond County.
This dataset has the following 9 columns:
| Column Name | API Column Name | Data Type | Description | Sample Values |
|---|---|---|---|---|
| deployment_id | deployment_id | text | unique identifier for ADCP deployment. IDs are assigned incrementally by deployment date within a county. A skipped ID (e.g., consecutive IDs are XY001 and XY003) indicates that an ADCP was deployed but no useable current data were recovered (e.g., the battery failed). | RC009 RC008 RC007 RC002 RC005 view top 100 |
| waterbody | waterbody | text | waterbody in which the ADCP was deployed. | LeBlanc Harbour Lennox Passage Arichat Harbour St. Peters Inlet Carry Passage view top 100 |
| station | station | text | specific area where ADCP was deployed. | AQ1438 AQ1439 Lazares Island Jerseyman Island St. Peters Inlet view top 100 |
| timestamp_utc | datetime | calendar_date | timestamp of the start of the ensemble (in UTC). Current speed and direction recorded at each timestamp are an average of many measurements recoded during the ensemble. See the “Nova Scotia Current Data Deployment Information” dataset for ensemble details for each deployment. | 2023-09-30T12:10:00.000 2023-10-01T13:30:00.000 2023-10-02T01:00:00.000 2023-09-29T11:10:00.000 2023-10-02T01:20:00.000 view top 100 |
| sensor_depth_below_surface_m | sensor_depth_below_surface_m | text | the depth of the ADCP below the surface (metres), measured by the ADCP sensor. Changes with the tide. | 20.04 20 19.98 20.03 19.97 view top 100 |
| bin_height_above_sea_floor_m | bin_height_above_sea_floor_m | text | distance from the seafloor to the centre of the measurement bin (metres). | 5.1 3.1 2.6 3.6 2.1 view top 100 |
| bin_depth_below_surface_m | bin_depth_below_surface_m | text | distance from the surface to the centre of the measurement bin (metres). Calculated as sensor_depth_below_surface_m + sensor_height_above_sea_floor_m - bin_height_above_sea_floor_m. See “Nova Scotia Current Data: Deployment Information” dataset (https://data.novascotia.ca/d/rs2e-ekha) for sensor_height_above_sea_floor_m. | 5 4 3.98 4.98 4.04 view top 100 |
| sea_water_speed_m_s | sea_water_speed_m_s | number | water speed for corresponding depth bin and timestamp (m / s). | 0.016 0.013 0.009 0.017 0.011 view top 100 |
| sea_water_to_direction_degree | sea_water_to_direction_degree | number | direction of water flow for corresponding depth bin and timestamp (degrees). Measured travelling away from the ADCP sensor relative to True North (a reading of 90 degrees describes current travelling from west to east). | 253.08 73.08 298.08 342.42 343.08 view top 100 |
