Sea Lamprey positions from a positional acoustic telemetry array in Lake George, North Channel of the St. Marys River during the 2012 spawning year.
Format
A data frame with 21043 rows and 14 variables:
- DETECTEDID
transmitter identifier (channel, frequency, code space, and ID code)
- DATETIME
position timestamp, in UTC
- X,Y
horizontal and vertical position on local grid, in meters
- D
assumed depth at time of detection, in meters (NOT from depth/pressure sensor)
- LAT,LON
position latitude and longitude, decimal degrees (west is negative); CRS: WGS84
- n
?
- HPE
horizontal position error; calculated by VEMCO
- HPEm
horizontal position error, in meters; calculated by VEMCO
- TEMP
temperature at time of detection (from temperature sensor)
- DEPTH
depth at time of detection (from pressure sensor)
- ACCEL
acceleration at time of detection (from accelerometer)
- DRX
receivers that detected the associated transmission
Details
Data were collected as part of the GLATOS project SMRSL https://glatos.org/home/project/SMRSL
Positions were calculated using the Vemco Positioning System.
