Schedule • • We have started work already Must ship all items so they get to SP when it opens Organize shipments so parts are easily found We have about 6 months--must be very careful on what we do Mar 19 -23, 2005 Berkeley 11

Stay focused on goals • Priorities: – Thing we must do – Things we should do – Things that would be nice 1 2 3 • Eliminate dependencies among tasks • Keep an eye on how long it takes to do here • Keep another eye on how long it takes to implement at the pole • Keep both eyes on drilling 12 holes Mar 19 -23, 2005 Berkeley 12

Drill Logging and Analysis Mar 19 -23, 2005 Berkeley 13

Implementation--Introduction • • Layout-surveying Pilot holes— 4” coring drill Firn Drill---down to 60 meters—water pools HW Drilling—straightness, depth, logging String Deployment—depth, location, logging Freeze-In— 4 -5 day monitoring-Counting House Data Management—drillers, deployers Off-line—real-time analysis, Pole, Madison Mar 19 -23, 2005 Berkeley 14

Drilling Data • Drill Operations: depth, calipers, theta, vital parameters • Data updates at rate of 4 Hz (250 ms). • Data-Bridge—between drill net and SP-net. With updates every 5 minutes— 1200 updates • Drill Monitoring: Off-line, Real-Time • Pole Monitoring---full analysis and logging • Madison Monitoring—full analysis and logging as the satellite permits. Mar 19 -23, 2005 Berkeley 15

Off-line Real-Time Analysis At South Pole and Madison • • • Tension (cable and drill-head) Depth (from winch payout and pressure) Hole Diameter—Calipers Drill-Angle—Straightness, Theta Logging X-Y or “birds-eye” plots Mar 19 -23, 2005 Berkeley 16

HOLE 1 Mar 19 -23, 2005 Berkeley 22

Hole #1 Summary • 22 hrs—large tilt angle, buried drill? • 27 -33 hrs—buoyant drill, buried drill, lost nozzle? • 40 hrs—buried drill, lost part of weights • 43 hrs—lost additional part of weight-stack • 45 hours buried drill • 33 -50 hours, drill difficult to steer. • Difficulty controlling hole diameter Mar 19 -23, 2005 Berkeley 23

Hole #2 (21 -A) • Move tower by about 8 meters • Make 2 nd attempt at hole drilling Mar 19 -23, 2005 Berkeley 24

Drill Oscillations • Demonstrates need for fast-response instruments like drill load-cells, and cable/winch load-cells. • Possible need for additional instruments like accelerometers to actually determine drillhead’s instantaneous velocity and position. Mar 19 -23, 2005 Berkeley 34
