Effects of active layer seasonal dynamics and plant phenology on CO2 land-atmosphere fluxes at polygonal tundra in the High Arctic, Svalbard
Nicoletta Cannone,Stefano Ponti,Hanne H. Christiansen,Torben R. Christensen,N. Pirk,Mauro Guglielmin +5 more
TL;DR: In this article, the authors analyzed the CO2 fluxes at a polygonal tundra site in Adventdalen (Svalbard) during one full growing season across a vegetation and environmental gradient to understand how the interaction of different abiotic (thaw depth, ground surface temperature (GST), soil moisture, photosynthetic active radiation -PAR) and biotic (leaf area index (LAI), and plant phenology) factors affect the CO 2 fluxes and identify the drivers of Net Ecosystem Exchange (NEE) and Ecosystem Respiration (ER).

TL;DR: In this paper, the authors used a calibrated and validated model (soil-plant-atmosphere; SPA) to estimate net ecosystem exchange (NEE), gross primary production (GPP), ecosystem respiration (Reco), and internal C processing across eight full years.

Environmental Monitoring and Research in the Abisko Area—An Overview
TL;DR: The long-term monitoring of the Station on processes related to the climate, and to the physical, biotic, and chemical environmental conditions is particularly addressed.

Carbon partitioning in a wet and a semiwet subarctic mire ecosystem based on in situ 14C pulse-labelling
TL;DR: In this paper, the authors quantify the partitioning of recent assimilates to above-and below-ground carbon (C) pools in two subarctic mire ecosystems using in situ C-14 pulse-labelling.

TL;DR: This paper and the assessment in the following papers of this Ambio Special Issue focus on biota (plants, animals and microorganisms) and processes in the region beyond the northern limit of the closed forest (the taiga), but they also include processes south of this boundary that affect ecosystems in the Arctic.
