Lake bathymetry measurements for sampled lakes in and around the Trail Valley Creek watershed, NT

The bathymetry data was spatially interpolated, producing raw files and processed data. The raw bathymetry files, named “all_lakes_bath_raw”, contains raw lake depth measurements collected using a Garmin echoMAP CHIRP 42dv fish finder and a GT20-TM transducer mounted to a canoe.

Bathymetric data was extracted from the Garmin device using QDCConverter 2.5 (github.com/interlark/qdc-converter/releases/tag/v2.5), where the data layer was set to the recommended setting of “1”. The raw bathymetric data were processed into the bathymetry files named “all_lakes_bath”, where these bathymetry readings used an unknown spatial interpolation from the raw depth readings. The “BathymetryGPX” files support a shapefile of the recorded positions at regular intervals as the team traversed the different lakes.
