A spatial dataset (sf object) containing information about acoustic receiver deployments in Stoney Lake, Ontario, Canada. This dataset includes receiver locations, deployment periods, and site characteristics.
Format
An sf data frame with 145 rows and 7 columns:
- station_id
Character. Unique identifier for receiver station (e.g., "T1-1")
- x
Numeric. Longitude coordinate (decimal degrees, WGS84)
- y
Numeric. Latitude coordinate (decimal degrees, WGS84)
- depth_m
Numeric. Water depth at receiver location (meters)
- deploy_datetime_UTC
POSIXct. Date and time of receiver deployment (UTC)
- recover_datetime_UTC
POSIXct. Date and time of receiver recovery (UTC)
- geometry
sf geometry column with UTM Zone 17N coordinates
Details
This dataset contains spatial and temporal information for acoustic receivers deployed in Stoney Lake as part of fish telemetry studies. The receivers were deployed across multiple years (2022-2024) to monitor fish movements. The coordinate reference system is UTM Zone 17N (EPSG:32617).
Each receiver has coordinates in both geographic (decimal degrees) and projected (UTM) coordinate systems. Deployment periods vary by station, with some receivers being redeployed multiple times.
