John Barnard,
Loomis Partners
Chief Surveyor, Contributes to
Earthwatch Research in Iceland
July 2008
John Barnard, R.P.L.S. and Chief Surveyor at Loomis Partners, joined a team of
Earthwatch
Institute
scientists on a glaciological expedition in Iceland. Led by
Dr. Andy Russell, a
scientist from Newcastle University, the research group
included ten US high school student volunteers. As a co-principal
investigator, John was involved in the surveying of the upland topography
and bathymetry of three pro-glacial lakes (depths to ~420 feet)
in Skaftafell National Park, part of ongoing Earthwatch expeditions
to study the effects of how glaciers transport and release sediment
into meltwater systems.
An Earthwatch volunteer and field team leader, John has participated
in two previous expeditions to survey these sites along the front of
the Skeidararjokull Glacier. Loomis Partners'
Terrestrial
Laser Scanning System provides
the research team with a tool that can survey large areas in a short
time period. These annual survey data sets are being compiled to
model the changes in this dynamic landscape.

In 1996 the Skeidararjokull Glacier was the site of a massive flood
that was caused by a volcanic eruption beneath the vast Icelandic
ice cap, one of the most geologically active areas in the world (Earthwatch
website).

Remarkably, one of these glacial outburst floods (known as “jokulhlaups”)
occurred during the 2008 expedition (see photo at left), and the group
was able to survey the rising, peak, and waning stages of the flood,
which was associated with the draining of Graenalon, Europe’s
largest ice-damned lake. Loomis' Terrestrial Laser Scanner was used
to survey the glacial vents, from which the water was erupting, at
two hour intervals for 48 hours. This is the first time that laser
scanning technology has been used to monitor one of these events.

This survey work will aid scientists in understanding the volatile
Icelandic landscape as well as glacial landforms that shape North
America and Europe.
