While getting ready to go on assignment to a huge
glacier in a remote corner of Norway this past August,
Associate Editor Erico Guizzo [photo] got an urgent,
last-minute request from the engineering team he was
meeting there. The researchers had run short of critical
components for the electronic probes they were building
for their experiments at the glacier.

So Guizzo, who holds a bachelor's degree in
electrical engineering from the University of São Paulo,
in Brazil, quickly put in an order to Digi-Key Corp.,
the huge Minnesota-based electronics components
retailer. Days later, when he boarded his flight to
Europe, he had 30 op-amp chips and 10 analog switches
carefully packed in his luggage.
"It made me feel like I was part of the mission,"
Guizzo says.
Guizzo's story, "Into Deep Ice," describes his week
on the glacier, which is named the Briksdalsbreen. It
tells of the engineers' clever improvisations and a few
weird setbacks, including the loss of some wires to
hungry goats.
The team, based at the University of Southampton, in
England, showed how a wireless glacier-monitoring system
could record environmental observations such as
temperature, pressure, and electrical resistivity that
simply couldn't be collected with conventional
instrumentation. It's a huge step toward their ultimate
goal of understanding how the glacier is responding to
climate change.
If it were an ice cube, the Briksdalsbreen would
measure one kilometer on a side. But the glacier, which
had been growing until recently, now appears to be
melting. What's going on? "That's what the Southampton
team hopes to find out," Guizzo says.
