title: Circumpolar dataset of Soil Organic Carbon north of treeline derived from ENVISAT ASAR GM, link to GeoTIFF

description: A new approach for the estimation of soil organic carbon (SOC) pools north of the tree line has been developed based on synthetic aperture radar (SAR; ENVISAT Advanced SAR Global Monitoring mode) data. SOC values are directly determined from backscatter values instead of upscaling using land cover or soil classes. The multi-mode capability of SAR allows application across scales. It can be shown that measurements in C band under frozen conditions represent vegetation and surface structure properties which relate to soil properties, specifically SOC. It is estimated that at least 29 Pg C is stored in the upper 30 cm of soils north of the tree line. This is approximately 25 % less than stocks derived from the soil-map-based Northern Circumpolar Soil Carbon Database (NCSCD). The total stored carbon is underestimated since the established empirical relationship is not valid for peatlands or strongly cryoturbated soils. The approach does, however, provide the first spatially consistent account of soil organic carbon across the Arctic. Furthermore, it could be shown that values obtained from 1 km resolution SAR correspond to accounts based on a high spatial resolution (2 m) land cover map over a study area of about 7 × 7 km in NE Siberia. The approach can be also potentially transferred to medium-resolution C-band SAR data such as ENVISAT ASAR Wide Swath with ~120 m resolution but it is in general limited to regions without woody vegetation. Global Monitoring-mode-derived SOC increases with unfrozen period length. This indicates the importance of this parameter for modelling of the spatial distribution of soil organic carbon storage.
description: The dataset contains circumpolar estimates for Soil Organic Carbon (SOC) in kg/m² north of treeline derived from ENVISAT ASAR GM. - Band 1: SOC 0 - 30 cm - Band 2: SOC 0 - 100 cm - Band 3: Quality flag - value 1 for potential area of underestimation - Band 4: Quality flag - value 1 for potential area of overestimation

title: Microbe abundance and biomass at station SEPT-1999-K6 in the Northeastern Aegean Sea

description: Borax-buffered formalin (final concentration 2% formaldehyde). Slides for nanoflagellates counting were stored at -20°C. Subsamples (10-30 ml) were concentrated on 25mm black polycarbonate filters of porosity 0.6µm for nanoflagellates, stained with DAPI for 10 min (Porter & Feig 1980) and filtered. Heterotrophic (HF) and photototrophic (PF) nanoflagellates were distinguished using UV and blue excitation and enumerated. Nanoflagellates were classified in size categories and the biovolume was calculated.Abundance data were converted into C biomass using 220fgC um-3 (Borsheim & Bratbak 1987) for nanoflagellates.Bacterial production was estimated by the 3H-leucine method (Kirchman et al. 1986, Kirchman 1993). At each depth, duplicate samples and a control were incubated with 1 nM L-[4,5 3H]-leucine (specific activity 128 Ci mmol-1) and 19 nM non radioactive leucine. Samples were incubated in the dark, at in situ temperature.

description: Bacterial countsSamples for enumeration of bacterial abundance were drawn from Niskin bottles and immediately preserved in 20 mL glass scintillation vials with 0.2 µm filtered (Millex-GS, Millipore Corp.) formalin (2% final concentration). Preserved samples were stored dark in a refrigerator. Each sample was poured over triplicate polycarbonate membranes (0.2 µm black Nuclepore) underlain by pre-wetted backing filters (Sartorius #11306) which aid in distributing cells in an even manner on the Nuclepore surface. Cells were stained for 10 minutes with DAPI at a final concentration of 2 µg/ml and then drawn through the filters at a vacuum pressure of about 150 mm Hg. The filters were examined by epifluorescence microscopy (Leitz Orthoplan) under ultraviolet excitation from a mercury arc lamp (HBO 100W).Cyanobacterial countsSamples for enumeration of cyanobacterial abundance (20-100 ml) were freshly filtered in triplicate onto 0.2 µm black Nuclepore membranes which were underlain by backing filters. The membranes were stored refrigerated after having been covered in a drop of immersion oil. Cyanobacteria were enumerated by epifluorescence microscopy under green excitation (Leitz block N2).

title: (Table 1) Biovolume variations of cyanobacteria and total phytoplankton in the Frederiksborg Slotsso, Denmark

description: Several studies have shown that submerged macrophytes provide a refuge for zooplankton against fish predation, whereas the role of emergent and floating-leaved species, which are often dominant in eutrophic turbid lakes, is far less investigated. Zooplankton density in open water and amongst emergent and floating-leaved vegetation was monitored in a small, eutrophic lake (Frederiksborg Slotsso) in Denmark during July-October 2006. Emergent and floating-leaved macrophytes harboured significantly higher densities of pelagic as well as plant-associated zooplankton species, compared to the open water, even during periods where the predation pressure was presumably high (during the recruitment of 0+ fish fry). Zooplankton abundance in open water and among vegetation exhibited low values in July and peaked in August. Bosmina and Ceriodaphnia dominated the zooplankton community in the littoral vegetated areas (up to 4,400 ind/l among Phragmites australis and 11,000 ind/l between Polygonum amphibium stands), whereas the dominant species in the pelagic were Daphnia (up to 67 ind/l) and Cyclops (41 ind/l). The zooplankton density pattern observed was probably a consequence of concomitant modifications in the predation pressure, refuge availability and concentration of cyanobacteria in the lake. It is suggested that emergent and floating-leaved macrophytes may play an important role in enhancing water clarity due to increased grazing pressure by zooplankton migrating into the plant stands. As a consequence, especially in turbid lakes, the ecological role of these functional types of vegetation, and not merely that of submerged macrophyte species, should be taken into consideration.

title: (Table 1) Surface water chemistry of northern Victoria Land lakes

description: Concentrations of major ions, silicate and nutrients (total N and P) were measured in samples of surface water from 28 lakes in ice-free areas of northern Victoria Land (East Antarctica). Sixteen lakes were sampled during austral summers 2001/02, 2003/04, 2004/05 and 2005/06 to assess temporal variation in water chemistry. Although samples showed a wide range in ion concentrations, their composition mainly reflected that of seawater. In general, as the distance from the sea increased, the input of elements from the marine environment (through aerosols and seabirds) decreased and there was an increase in nitrate and sulfate concentrations. Antarctic lakes lack outflows and during the austral summer the melting and/or ablation of ice cover, water evaporation and leaching processes in dry soils determine a progressive increase in water ion concentrations. During the five-year monitoring survey, no statistically significant variation in the water chemistry were detected, except for a slight (hardly significant) increase in TN concentrations. However, Canonical Correspondence Analysis (CCA) indicated that other factors besides distance from the sea, the presence of nesting seabirds, the sampling time and percentage of ice cover affect the composition of water in Antarctic cold desert environments.
