Organic Carbon Pools and Genesis of Alpine Soils with Permafrost: A Review

  title={Organic Carbon Pools and Genesis of Alpine Soils with Permafrost: A Review},
  author={James G. Bockheim and Jeffrey S. Munroe},
Abstract Soils with mountain permafrost occupy 3.5 million km2 worldwide, with 70% in central Asia. High-mountain environments have “warm” permafrost, with surface permafrost temperatures of -0.5 to -2 °C and deep active layers (2 to 8 m). From a global database of 41 sites and 312 pedons, alpine soils with permafrost are strongly acid (pH = 5.0 to 5.5), have intermediate cation-exchange capacities (20 to 25 cmolc/kg) and base saturation (44% to 85%), and commonly have an isotic mineral class… 

Soil organic carbon storage in a mountain permafrost area of Central Asia (High Altai, Russia)

This study investigates SOC storage in an under-sampled mountain permafrost area in the Russian High Altai using a GIS-based land cover classification and finds that the top 100 cm of soils in Aktru Valley and the adjacent Kuray Basin only holds on average 2.6 kg C m−2, representing a ‘negative’ feedback on global warming.

Evidence for non-steady-state carbon emissions from snow-scoured alpine tundra

Seven years of sustained carbon emissions from snow-scoured alpine tundra including respiration of older carbon substrate from solifluction lobes associated with permafrost during the winter are shown to have global implications for the mountain carbon balance and corresponding resource allocation to lower elevation.

Global Distribution of Cryosols with Mountain Permafrost: An Overview

About 30 per cent of the mountain soils with permafrost have an active layer depth (ALD) of less than 1 or 2 m and, therefore, can be classified as Cryosols. Mountain Cryosols have a total area of

Selective Leaching of Dissolved Organic Matter From Alpine Permafrost Soils on the Qinghai‐Tibetan Plateau

Ongoing global temperature rise has caused significant thaw and degradation of permafrost soils on the Qinghai‐Tibetan Plateau (QTP). Leaching of organic matter from permafrost soils to aquatic

Different chemical composition and storage mechanism of soil organic matter between active and permafrost layers on the Qinghai–Tibetan Plateau

Purpose Although many studies have paid attention to the storage and dynamics of organic carbon (OC) in the Arctic permafrost, there are limited reports for low-latitude alpine permafrost ecosystems

Environmental controls on soil organic carbon and nitrogen stocks in the high‐altitude arid western Qinghai‐Tibetan Plateau permafrost region

While permafrost in the circum‐Artic has great influence on soil organic carbon (SOC) and total nitrogen (TN) stocks, this might not be the case in low‐latitude arid permafrost regions. We test this



Soil Organic Carbon Pools and Stocks in Permafrost-Affected Soils on the Tibetan Plateau

Permafrost-affected soils in discontinuous permafrost environments are susceptible to soil moisture changes due to alterations in quantity and seasonal distribution of precipitation, increasing temperature and therefore evaporation.

Alpine grassland soils contain large proportion of labile carbon but indicate long turnover times

Abstract. Alpine soils are expected to contain large amounts of labile carbon (C) which may become a further source of atmospheric carbon dioxide (CO2) as a result of global warming. However, there

Soil organic carbon storage and distribution in Arctic Tundra, Barrow, Alaska

Soil organic C (SOC) levels were determined to a depth of 100 cm for the nine units designated on a 1957 1:20 000 soil map of Barrow, AK prepared by J.V. Drew. The legend was updated by converting

Soil organic carbon pools in the northern circumpolar permafrost region

The Northern Circumpolar Soil Carbon Database was developed in order to determine carbon pools in soils of the northern circumpolar permafrost region. The area of all soils in the northern permafrost

Soils and landscapes of Kärkevagge, Swedish Lapland.

Karkevagge, a glacially eroded valley above the Arctic Circle in Sweden, is of particular interest because research findings there in the 1950s challenged the view that chemical weathering is

Soil Organic Matter Characteristics in Sporadic Permafrost-affected Environment (Creux du Van, Switzerland)

Abstract In permafrost-affected sites, soil forming processes appear to be closely connected with organic matter (OM) accumulation. In this work OM composition and nutrient availability has been
