“…The field station is a part of the International Network for Terrestrial Research and Monitoring in the Arctic (INTERACT, eu-interact.org) and is actively used by Russian and foreign scientists for studies of the functioning of mire ecosystems. Over the past years, the Mukhrino bog was the main object of numerous experimental study of GHG fluxes (Glagolev et al 2011;Alekseychik et al 2017), geochemistry and physical, chemical, and biochemical properties of peat (Stepanova and Pokrovsky 2011;Szajdak et al 2016), mire hydrology (Bleuten and Filippov 2008), and microbiology including mycology (Filippova et al 2015).…”

The continuous field measurements of net ecosystem exchange (NEE) of CO 2 were provided at ridge-hollow oligotrophic bog in the Middle Taiga zone of West Siberia, Russia in 2017-2018. The model of net ecosystem exchange of CO 2 was suggested to describe the influence of different environmental factors on NEE and to estimate the total carbon budget of the bog over the growing season. The model uses air and soil temperature, incoming photosynthetically active radiation (PAR) and water table depth, as the key factors influencing gross primary production (GPP) and ecosystem respiration (ER). The model coefficients were calibrated using the data collected by automated soil CO 2 flux system with two transparent long-term chambers placed at large hollow and small ridge sites. Experimental and modeling results showed that the Mukhrino bog acted over the study period as a carbon sink, with an average NEE of-87.7 gC m-2 at the hollow site and-50.2 gC m-2 at the ridge site. GPP was-344.8 and-228.5 gC m-2 whereas ER was 287.6 and 140.9 gC m-2 at ridge and hollow sites, respectively. Despite of a large difference in NEE estimates between 2017 and 2018 the growing season variability of NEE were quite similar.

Net ecosystem exchange and energy fluxes measured with the eddy covariance technique in a western Siberian bog

et al. 2017

Abstract. Very few studies of ecosystem-atmosphere exchange involving eddy covariance data have been conducted in Siberia, with none in the western Siberian middle taiga. This work provides the first estimates of carbon dioxide (CO 2 ) and energy budgets in a typical bog of the western Siberian middle taiga based on May-August measurements in 2015. The footprint of measured fluxes consisted of a homogeneous mixture of tree-covered ridges and hollows with the vegetation represented by typical sedges and shrubs. Generally, the surface exchange rates resembled those of pinecovered bogs elsewhere. The surface energy balance closure approached 100 %. Net CO 2 uptake was comparatively high, summing up to 202 gC m −2 for the four measurement months, while the Bowen ratio was seasonally stable at 28 %. The ecosystem turned into a net CO 2 source during several front passage events in June and July. The periods of heavy rain helped keep the water table at a sustainably high level, preventing a usual drawdown in summer. However, because of the cloudy and rainy weather, the observed fluxes might rather represent the special weather conditions of 2015 than their typical magnitudes.

“…A commonly applied vegetation index, the NDVI has long been used in ecology, remote sensing, and geography to assess the characteristics of green vegetation, including its amount (biomass), nature, and status. NDVI is a benchmark for spectral band ratio applications [40]. The NDVI monitors the vegetation state, density, and intensity of plant growth, and can be calculated from the reflectance values of the red (RED) and the infrared band (NIR).…”

Water quality is highly affected by riverside vegetation in different regions. To comprehend this research, the study area was parted into wet and dry regions. The WASP8 was applied for the simulations of water quality profile over both Waterways selected from each region. It was found that the Ara Waterway, located in the wet regions, has a higher water quality variation in seasonal scale than that of the Yamuna Waterway, which is in the dry region. The interrelationship between river water quality variables and NDVI produce higher association for water quality variables with Pearson correlation coefficient values of about 0.66, 0.68 and −0.58, respectively, over the annual and seasonal scales in the energy limited regions. This approach will help in monitoring the seasonal variation and effect of the vegetation biomass on water quality for the sustainable water environment.
