- Description:
- This dataset contains data of an acoustic positioning telemetry study on the Albert canal, in a 200x150 m area directly upstream of the navigation lock complex of Kwaadmechelen, Belgium. European silver eels (Anguilla anguilla) and Atlantic salmon smolts (Salmo salar) were tagged with 69-kHz acoustic transmitters (Vemco, Halifax, NS) and detected by acoustic receivers attached at the canal walls and ship guiding structures of the navigation lock complex. The study comprises 3 deployments between 2015-11-25 and 2017-06-16. At the end of each deployment, receivers were offloaded and the detections were sent to Vemco for processing and calculation of the VPS positions. Additionally, we used the raw detection data to calculate positions by use of the YAPS algorithm. Files: • metadata.csv: definitions for the fields in deployments.csv, receivers.csv, transmitters.csv, detections.csv, positions_vps.csv, positions_yaps.csv and gps_track.csv. • deployments.csv: Start and end date of the 3 deployments. At the end of each deployment, receivers were offloaded and the detections were sent to Vemco for processing and calculation of the VPS positions. • receivers.csv: Positions and specifications of the used receivers (VR2W and 1 VRT2-x). Receivers with short_id ST8 and ST8-2 have the same receiver_id because it concerns the same receiver deployed in another position (changed on 2017-04-05 08:47). The short_id denotes this position. • transmitters.csv: Specifications of the used transmitters. Position and start_date/end_date are only specified for fixed transmitters (i.e. reference-Rx and synchronisation-Sx transmitters). S8-2, S9-2 and R4 were added during the last deployment, and have therefore start dates that differ from deployment start dates. Synchronisation transmitters Sx were collocated with receivers with corresponding STx-id. S8 and S8-2 have the same transmitter_id because it concerns the same transmitter deployed in another position. • detections.csv: Raw receiver detections with millisecond time accuracy, needed to perform the YAPS positioning algorithm. The synchronised time was calculated from the original time by use of the synchronisation transmitters: JennaVergeynst. (2019, November 13).
