Plant roots play a critical role in ecosystem function in arctic tundra, but root dynamics in
these ecosystems are poorly understood. To address this knowledge gap, we synthesized …

Knowledge of soils in the permafrost region has advanced immensely in recent decades,
despite the remoteness and inaccessibility of most of the region and the sampling limitations …

Soils and other unconsolidated deposits in the northern circumpolar permafrost region store
large amounts of soil organic carbon (SOC). This SOC is potentially vulnerable to …

Arctic tundra soils store large amounts of carbon (C) in organic soil layers hundreds to
thousands of years old that insulate, and in some cases maintain, permafrost soils,. Fire has …

The objective of this paper is to review research conducted over the past decade on the
application of multi-temporal remote sensing for monitoring changes of Arctic tundra lands …

The Arctic soil organic-carbon pool is a significant, but poorly constrained, carbon store. The
most cited pool size estimates are based on a study that severely undersamples Arctic soils …

High-latitude terrestrial ecosystems are key components in the global carbon cycle. The
Northern Circumpolar Soil Carbon Database (NCSCD) was developed to quantify stocks of …

Arctic warming may cause the release of vast amounts of soil organic carbon (SOC) from
permafrost, which will manifest itself in the fluxes and composition of organic carbon in …

Permafrost is a defining characteristic of the Arctic environment. However, climate warming
is thawing permafrost in many areas leading to failures in soil structure called thermokarst …

This paper reports results of an experiment initiated in 1977 to determine the effects of
climate on permafrost in Alaska. Permafrost observatories with boreholes were established …
