2002-03 Photos--SPRESSO project

set up camp

The 2002-03 project camp site 5 miles from the station. (map)

big box
One of the first tasks of the season--hauling the building and vaults out to the drill site. Here's equipment operator Sandy (Dave) Sandison along with Kent.
empty shell
Oh, here's a look inside that finished building. We're looking toward the electrical room at the far end; the cold room with the ladder to the surface is behind the wall at left.
slotted hole
Here goes the building into the hole (15 December 2002)...
red vaults




...followed by the shallow vault structure.
bury me not...
Like so.
in hot water
Meanwhile, the power and data from the station get installed. Close to the station a hot water trencher was used, to avoid potential damage to existing utilities.

A closer view. Hard at work in these two pictures are Billy Texter and Peter Koson (JC).
on the straight and narrow
Away from the station, the "ditch witch" was used (JC).
the reel thing
Here's the cable installation sled being put together...
putting it down
...and here are Ross Thorsen, Dave Carlson, and an unidentifiable GA installing the cables (JC).
a joining roomLater, a heated shack was towed along the trench for splicing the cables... seen here is Dave Carlson. One interesting problem here is that the ice is "stretching" between SPRESSO and the station about 2-1/2 feet a year, or about 18 feet between 2000 and 2008. Various expansion provisions were made for the 3 cables--4160V power, ground, and fiber optics (data) (JC).
loop de loop
The cables get inspected every year. This is one of the expansion loops in the power cable (as seen in January 2008 when this box was modified). Future movement of the cable can be determined by measuring the two tape marks. And, the instrument site has a high-grade GPS antenna/receiver that helps track the position of SPRESSO relative to the station.
round we go
Meanwhile, the drilling operation was continuing. Here BK Grant (left) looks on as Kent Anderson, Terry Gacke, and Mark Albershardt deal with the drill.
scrape the plate
A closeup view of Kent Anderson with the reamer. They had the cutter at the top of the barrel as seen here; the bottom of the barrel would guide the reamer into the hole, while cuttings would be collected in the barrel (TG).
making it bigger
The reamer, here being dealt with by Mark and Lou Albershardt, and Bella Bergeron.
watch your feet


Inserting the reamer into the hole. The barrel would hold only about 1/2 meter of cuttings, so it made lots of trips up and down the hole (TG).
operating position
Here's Kent at the drill controls (TG).
all the way to...
A look down one of the boreholes. The first two holes were successfully reamed to 12" and a third "spare" hole was drilled with core samples taken.
Continue on to the instrument installation and completion.
