Digging Holes and Filling Batteries -- A party in Vidalia, Georgia

The SUGAR deployment team arrived en-masse on Saturday bringing the Line 2 personnel total to a whopping 45! The day started off with science and overview lectures by the SUGAR principle investigators Donna Shillington and Dan Lizarralde.  Students diligently rearranged the ten’s of Texan boxes into a makeshift lecture hall, complete with a projector and a Bluetooth sound system. 

With the science lecture complete and stomachs full of pizza, the entire group ventured out to conduct a practice deployment under the watchful eyes of the PASSCAL instrument team.  All 17 teams participated in the activity, standing in a single file line in front of our hotel digging practice holes, connecting the Texans to the geophones, and mindfully orientating them with their handy-dandy bubble levels. 

After a sweat filled hour under the Georgia sun, we caravanned back to the instrument center for a “battery party”. I call it a battery party in honor of the “streamer parties” that students will often participate in on active source seismic research cruises in which kilometers of cable need to be reeled off and rearranged.  In our case a battery party consisted of the 32 students placing 2 D-cell batteries inside each of the 2,000 Texans.  The instrument center quickly transformed from an orderly lecture hall into a mass of empty battery boxes and disassembled Texans though despite the apparent chaos, we got the job complete and the Texans filled in only a few short hours. 

Next up will be flagging the instrument locations and the actual deployment.  We have our fingers and toes crossed for dry weather and safe road conditions as the student teams prepare to set off on their flagging and deployment expeditions.
