USArray Station Removal Report Form V1.5
STATION CODE: TA.E28M
STATION LOCALE DESCRIPTION: Babbage River, YT, CAN
STATION REMOVAL LOG DATE: 20210719
STATION/SENSOR DOWN TIME (UTC): 00:02 (20210720 UTC)
REMOVAL DESCRIPTION: Sensor removed, borehole casing cutoff and capped, hut removed.
ACTIONS TAKEN: Powered the station down after collecting a final screenshot. Orientation was taken and sensor removed. The metal casing was cut off 6” below grade using a die grinder and capped with a 6" expansion end plug. The remaining hole was filled with local dirt and rock. Wind break rocks were scattered.
The hut was packed with the conduit, well cap, casing cut off, hut antenna mount and any other site debris and flown out to Eagle Plains.
CASING CONDITIONS: The casing was in good condition with no damage to the wellcap. No evidence of frost jacking. There was no evidence of animal damage.
SEISMOMETER REMOVAL: 2/3 difficulty.
The sensor pull required the scissor jack to break free. There was ice on the lower stuff sack and a large chunk covering the top of the sensor. There was minimal ice in the sand below the top of the sensor.
LAT/LONG OF SENSOR HOLE: N 68.60430, W -139.53493, WAAS enabled
Distance and azimuth to Hut from Sensor hole: 236", 319 degrees
Wind turbine: Spinning freely in the wind when we arrived.
Bottom of wellcap to grade level: 6”
SENSOR ORIENTATION MEASUREMENTS:
Measured with Octans Unit: n/a
Measured with rods on pin: No
Casing/wellcap marked with reference orientation: No
SENSOR ORIENTATION: N/A, pins covered by ice
Sensor orientation from install: 0.02 degrees
COMMENTS: The wind turbine was spinning happily in the wind. We did not test current inputs, but it seemed as though it was functioning.
