Soil microorganisms and methane emissions in response to short-term warming field incubation in Svalbard.

ABSTRACT:

Introduction

Global warming is caused by greenhouse gases (GHGs). It has been found that the release of methane (CH₄) from Arctic permafrost, soil, ocean, and sediment is closely related to microbial composition and soil factors resulting from warming over several months or years. However, it is unclear for how long continuous warming due to global warming affects the microbial composition and GHG release from soils along Arctic glacial meltwater rivers.

Methods

In this study, the soil upstream of the glacial meltwater river (GR) and the estuary (GR-0) in Svalbard, with strong soil heterogeneity, was subjected to short-term field incubation at 2°C (in situ temperature), 10°C, and 20°C. The incubation was carried out under anoxic conditions and lasted for fe
