Abstract
Instrumentation used for limnology, the study
of our world's lakes, is often developed for
oceanography and then gradually crossed
over as new technologies gain widespread
acceptance in the ocean community. Autonomous
underwater vehicles (AUVs) have been widely
deployed in naval operations, oil and gas
surveys, and scientific studies with limited
freshwater application. UBC-Gavia, a
Gavia-class AUV owned and operated by
the Environmental Fluid Mechanics group at
the University of British Columbia, has been
deployed as a monitoring and data collection
platform for lake bottom and water column
surveys alike.
Untethered, AUVs are a powerful tool as
they can often travel to regions that would be
logistically difficult or otherwise impossible
to access using more traditional surface based
survey tools (e.g. towed sonar arrays, ROVs,
profilers, etc.). These vehicles are well suited
to polar exploration as they can be deployed
from the ice surface with relatively low
infrastructure cost and provide significant
amounts of information on water bodies of
which there tends to be a dearth of collected
data. This is essential if mankind is to better
understand and monitor the widespread
impact that climate change is bringing to
our Polar Regions. In the past two decades,
several through-ice AUV surveys have been
conducted; however, UBC-Gavia was the first
AUV to be used in an under-ice limnological
study. The three case studies presented here
demonstrate UBC-Gavia as an important
platform for exploring our freshwater
environments with and without ice cover:
(1) Loch Etive, Scotland; (2) Lake Ontario,
Canada; and, (3) Pavilion Lake, Canada.
