Retrieving the Stations, Downloading the Data
 |
Now that the shots are done, it's time to gather the instruments and collect some Data. Here, grad student Tim (Radford) retrieves a Texan/geophone station. |
| Some stations require three Texans for vertical, N/S, and E/W directions of motion. Others are vertical only. |  |
 |
EPIC staff member Dave Thomas collects stations. Pick-ax? Check. Safety vest? Check. Rain hat? Check. Compass? Check. GPS? Check. Clipboard and pen? Check. As stations are deployed and retrieved, the serial numbers of each Texan are recorded. This will be important later, when data files are being matched to locations. |
| Ron Clowes of UBC shows that even Principal Investigators (PI's) get their hands dirty on a project like this. |  |
 |
With the instruments back at the hangar, it's finally time to get some DATA. The EPIC team batch process 45 Texan digitizers (three crates with 15 Texans each) at a time. |
| Pnina scans returning digitizers into the computer. Every digitizer has a unique serial number, which is required to connect its data to the actual location for the station. |  |
 |
This is what it's all about - seismic data. Thousands of such squiggles will eventually reveal what lies hidden beneath the Coast Mountains. |
| Now that the shots are done, the hikers head to the trail again, this time to collect the stations they deployed days earlier. |  |

6 PM: the hikers, backpacks full of Texans and geophones, make their triumphant return. |
