Northern Alaska Connections III: Winter observations of in-situ snow depth,
2005-2008
It is very difficult to measure snow cover in the Arctic from satellite data. However, understanding
snowmelt and coverage in the Arctic is of great importance for climate research and global
warming studies in the Arctic. >> Go

Northern Alaska Connections II: Soil Moisture Measurement and Modeling
The Northern Alaska Coastal System and North Slope regions have extensive wetlands, despite
near desert precipitation levels. This is an energy-limited system, where evapotranspiration
is highly dependent on incoming solar radiation and relatively impermeable permafrost reduces
sub-surface water storage capacity in the flat landscape. >> Go

Northern Alaska Connections I: Measuring Solid Precipitation
In climate physics, snow is influential due to its high-reflectivity, ground-insulating properties,
and contribution to surface hydrology. Ground-based measurements of snow accumulation are
needed both to improve understanding of surface-atmosphere exchange processes and to provide
a testing mechanism for remote-sensing techniques. >> Go

Sea Ice Observations
Two IARC scientists have sailed on recent missions over the northern seas, each experiencing different
aspects of waters that seem to be warming. The summer of 2007 has set a new satellite-era (since
1979) record for the smallest amount of ice covering the Arctic Ocean. >> Go

Oshoro-maru cruise in the Chukchi Sea, August 5th-15th, 2007
In the eastern Chukchi Sea, the warm Pacific Summer Water flows northwardly along the Alaska coastal
area. This warm water is thought to be a trigger of sea ice melting along the northern Alaska
coastal area, resulting in drastic sea ice reduction in the western Arctic Ocean

Detailed Temperature Forecasting With Topoclimate Modeling
In order to forecast the weather, meteorologists look at two types of data – observational
data from balloons and weather stations and data coming from numerical models of the atmosphere
that are run on computers. ... >> Go

The highest concentrations of dissolved methane ever measured in the Arctic Ocean found
beneath the sea-ice on the Laptev Sea shelf
The Arctic Ocean is a vulnerable environment with unique ecosystems that are adapted to harsh conditions.
Enormous stores of methane gas (CH4), referred to commonly as the “Arctic Carbon Hyper Pool”,
are present in the Arctic Ocean sediments.... >> Go

Global Outlook for Ice and Snow
Ice, snow and climate change are closely linked. The Global Outlook for Ice and Snow investigates
those linkages. It also presents information on the trends in ice and snow, the outlook for this
century and beyond and the consequences to ecosystems and human well-being of these changes.
It covers all parts of the cryosphere (the world of ice): snow, land ice, sea ice, river and
lake ice, and frozen ground. This publication is from the United Nations Environment Programme
(see author list for
IARC participation). ... >> Go
