OVERVIEW
The 2004 Joint Assembly, a partnership between the Canadian Geophysical
Union (CGU), American Geophysical Union (AGU), Society of Exploration
Geophysicists (SEG), and the Environmental and Engineering Geophysical
Society (EEGS), is being held in Montreal, Canada. The Program Committee
is developing a Union-wide science program in the traditional AGU form
and spirit. In addition, sessions related to the uses or applications of
the geophysical sciences will be provided.
SESSION DESCRIPTION
Arctic hydrology is now recognized as an important component of the
global climate system via the delivery of freshwater to the Arctic
Ocean. Additionally, the monitoring of high latitude freshwater flux is
increasingly relied upon to act as an integrator of the complex land
surface hydrological processes occurring throughout the pan-Arctic
region. The estimation of river discharge has generally been regarded as
the most accurate of the commonly monitored variables. However, with
increasing reliance on this parameter for detecting change and for
validating models over continental scales it has become important to
understand the trends, variability, and errors associated with these
measurements.
This session seeks to highlight:
(1) The current state of estimates of the high latitude freshwater flux
to the ocean both in solid and liquid form and over monitored and
unmonitored land areas
(2) The ongoing changes in the regime of the pan-Arctic rivers due to
global change and human influences
(3) The uncertainties introduced into these estimates as a result of
error in gauging and computational techniques (e.g. rating curves) and
heterogeneous temporal and spatial distribution of gauges
