USArray Station Removal Report Form V1.5
STATION CODE: TA.I29M
STATION LOCALE DESCRIPTION: Ogilvie Camp, YT, CAN
STATION REMOVAL LOG DATE: 20210717
STATION/SENSOR DOWN TIME (UTC): 2108
REMOVAL DESCRIPTION: Sensor removed. TA gear removed. Grizzly cooler, borehole, and power infrastructure remains for GSC adoption.
ACTIONS TAKEN: Powered the station down after collecting a final screenshot. Sensor issued "remove" command, log file captured. Orientation was taken and the sensor was removed.
The VIE, Q330 and associated cabling were removed. The Grizzly cooler is staying in place – in it are 2 AGM batteries, power cables, GPS antenna and cable, DC power cable connecting to the power box inside the bunkhouse, and ethernet cable that follows the same path as the power cable inside the bunkhouse.
The small box containing the AC/DC convertor was left in place under the computer desk in the bunkhouse. It was unlugged. The Mikrotik router was removed, the ethernet cable into the Highways network switch was disconnected. Everything was left tidy under the table.
A Morningstar charge controller wired with yellow and red Souriau bulkheads was plugged into the yellow (DC power input) and red (battery) power cables in the box.
CASING CONDITIONS: The well cap box was crushed by a large vehicle at some point, likely during snow plowing. We were unsure whether it moved the borehole, STS5Field showed the tilt within tolerance, but the sensor was out of level on all three channels.
SEISMOMETER REMOVAL: 2/3 difficulty. The sensor required a handy man jack to come out, this after the scissor jack was attempted. Possibly some small amount of water or ice down hole.
LAT/LONG OF SENSOR HOLE: N 65.36092, W -138.30629, WAAS enabled
Distance and azimuth to Hut from Sensor hole: 132", 109 degrees
Wind turbine: [not present]
Bottom of wellcap to grade level: 5”
SENSOR ORIENTATION MEASUREMENTS:
Measured with Octans Unit: b/c 5007004, s/n 34531002
Measured with rods on pin: Yes
Casing/wellcap marked with reference orientation: No
SENSOR ORIENTATION: 0.80 degrees
Sensor orientation from install: 0.01 degrees
COMMENTS: The shattered wellcap box was removed and the borehole was temporarily capped. A new wellcap box will be installed on the borehole when we return to stage heli ops at the Ogilvie Highways camp.
