Evidence and Implications of Recent Climate Change in Northern Alaska and Other Arctic Regions
The Arctic climate is changing. Permafrost is warming, hydrological processes are changing and biological and social systems are also evolving in response to these changing conditions. Knowing how
Acclimation of ecosystem CO2 exchange in the Alaskan Arctic in response to decadal climate warming
Summer CO2 flux data for two Arctic ecosystems from 1960 to the end of 1998 shows that a return to summer sink activity has come during the warmest and driest period observed over the past four decades, and indicates a previously undemonstrated capacity for ecosystems to metabolically adjust to long-term changes in climate.
Hydrograph separations in an arctic watershed using mixing model and graphical techniques
Storm hydrographs in the Upper Kuparuk River basin (142 km2) in northern Alaska were separated into source components using a mixing model and by recession analysis. In non‐Arctic regions, storm flow
Siberian Lena River hydrologic regime and recent change
[1] The long-term (1935–1999) monthly records of temperature, precipitation, stream flow, river ice thickness, and active layer depth have been analyzed in this study to examine Lena River hydrologic
Progress in permafrost hydrology in the new millennium
Increased attention directed at the permafrost region has been prompted by resource development and climate change. This review surveys advances in permafrost hydrology since 2000. Data shortage and
The role of surface storage in a low‐gradient Arctic watershed
The Arctic land surface water balance plays an important role in regulating the planetary heat balance and global ocean circulation. Lakes and wetlands are common features in the low‐gradient
Changes in Lena River streamflow hydrology: Human impacts versus natural variations
This study systematically analyzes long‐term (1936–1999) monthly discharge records for the major subbasins within the Lena River watershed in order to document significant streamflow hydrology
