Multi-technique surface geophysical surveys over Devon Ice Cap, Canadian Arctic

This dataset was acquired during a multi-technique surface geophysical campaign in May 2022 over Devon Ice Cap, Canadian Arctic.

Description of data:

Seismic
9 km of active source seismic reflection data
raw segy files for line A and line B
seismic observation log
matlab script for plotting a raw stack of line A and line B
coordinates of each seismic spread, with the ice surface elevation and estimated bed elevation

Transient electromagnetic (TEM) 
7 large loop TEM soundings 
with 500 x 500 m loop with receiver 250 m outside the loop (away from the transmitter)
USF files for each sounding
coordinates for each TEM sounding
TEM observation log  

Magnetotelluric (MT)
17 MT stations
raw, unprocessed EDI files 
coordinates for each MT station 
MT observation log

Acknowledgments

We thanks the Polar Continental Shelf Program for logistical support throughout the field season;  Rob Harris at Geonics for his support and help with the TEM method;  Zoe Vestrum at the University of Alberta for her MT support during deployment to the field;  

Funding

This work was funded by the Weston Family Foundation. The aircraft hours were funded by the Polar Continental Survey Program (PCSP) and ArcticNet. MT survey was supported by a NSERC Discovery Grant to Martyn Unsworth and the Future Energy Systems program at the University of Alberta.
