title: Biochemical investigation of multicorer sediment profile PS99/049-2

description: To detect and track the impact of large-scale environmental changes in a the transition zone between the northern North Atlantic and the central Arctic Ocean, and to determine experimentally the factors controlling deep-sea biodiversity, the Alfred- Wegener-Institute for Polar and Marine Research (AWI) established the deep-sea long-term observatory HAUSGARTEN, which constitutes the first, and until now only open-ocean long-term station in a polar region. Virtually undisturbed sediment samples have been taken using a video-guided multiple corer (MUC) at 13 HAUSGARTEN stations along a bathymetric (1,000 - 4,000 m water depth) and a latitudinal transect in 2,500 m water depth as well as two stations at 230 and 1,200 m water depth within the framework of the KONGHAU project. Various biogenic sediment compounds were analyzed to estimate the input of organic matter from phytodetritus sedimentation, benthic activities (e.g. bacterial exoenzymatic activity), and the total biomass of the smallest sediment-inhabiting organisms (size range: bacteria to meiofauna).

title: Taxa specific meiofauna density in the HAUSGARTEN area (Fram Strait) in 2014 (POLARSTERN cruise PS85)

description: Values were originally given per 10 cm**2 (rounded to 1 decimal place) and were recalculated to m**2 by multiplying by 1000.During PS85 (in 2014) bacteria density, meiofauna density, macrofauna density and macrofauna biomass was determined. For the bacterial density determination, sediment subsamples were taken with modified syringes (1.17 cm² cross-sectional area) from MUC recovered sediment cores and from benthic chambers. The first centimetre of each sample was stored in a 2 % filtered formalin solution at 4 °C. The acridine orange direct count (AODC) method (Hobbie et al., 1977) was used to stain bacteria in the subsamples and subsequently bacteria were counted with a microscope (Axioskop 50, Zeiss) under UV-light (CQ-HXP-120, LEj, Germany). For the determination of the meiofauna density and identification of meiofauna taxa, sediment subsamples were taken with modified syringes (3.14 cm² cross-sectional area) from MUC recovered sediment cores. The first centimetre of each sample was stored in borax buffered 4 % formaldehyde solution at 4 °C. The samples were sieved over a 1000 µm and 32 µm mesh. Both fractions were centrifuged three times in a colloidal silica solution (Ludox TM-50) with a density of 1.18 g/cm³ and stained with Rose 20 Bengal (Heip et al., 1985). Afterwards, the taxa were identified and counted. Foraminifera are not considered, as the extraction efficiency of Ludox for different groups of foraminifera is insufficient for a quantitative assessment of the group. Therefore, only metazoan meiofauna is recorded. After taking subsamples for bacteria and meiofauna densities, the remaining sediment from MUC recovered sediment cores and from the benthic chambers was used for macrofauna taxonomical identification, and density and biomass determination. For these macrofauna analyses only the 0-5 cm horizon from MUC sediment cores and the entire remaining sediment from the benthic chambers was used, sieved over a 500 µm mesh and stored in borax buffered 4 % formaldehyde and stained with Rose Bengal (Heip et al., 1985). Afterwards, macrofauna taxa were identified to the highest taxonomic level, counted and weighted (blotted wet weight).

title: Highly branched isoprenoid, sterol, and fatty acid fluxes of sediment trap FEVI10 and FEVI13

description: Two long-term mooring systems with two cone-shaped multi-sampling traps (FEVI10 and FEVI13; 2005-2007; SMT 230 K.U.M.; sampling area 0.5m2) was deployed in the HAUSGARTEN area at 79°01.00N, 04°20,62E (FEVI10) and 79°00,82N, 04° 20.5E (FEVI13).The highly branched isoprenoid IP25 as indicator for sea-ice distribution, the sterols campe- and sitosterol as proxies for terrestrial input, and the diatom-specific fatty acids (C16:1, C20:5) as well as the dinoflagellate-specific fatty acids (18:4, 22:6) were analysed by gas chromatography (GC) and/or gas chromatography-mass spectrometry (GC-MS). Biomarker analyses of campesterol (24-methylcholest-5-en-3β-ol), sitosterol (24-ethylcholest-5-en-3β-ol), fatty acids and IP25 were extracted with dichlormethane/methanol (1:1, v/v) and dichlormethane using separating funnels. For quantification of the lipid compounds, the internal standards 7-hexylnonadecane, C36 n-alkane, 19:0 FAME, and androstanol (5α-androstan-3β-ol, 20 μl/sample) were added prior to further analytical steps. The different compounds (IP25 and sterols) were separated via open column chromatography (SiO2) using n-hexane (for the hydrocarbons) and ethyl acetate/n-hexane (20:80 v/v for sterols) as eluent. The individual sterols were silylated with 500 μl BSTFA (bis-trimethylsilyl-trifluoroacet-amide) at 60°C for 2 h. After extraction with hexane, analyses were carried out. IP25 was quantified using its molecular ion m/z 350 in relation to the abundant fragment ion m/z 266 of 7-hexylnonadecane and by means of an external calibration curve (R2 = 0.9989) to balance the different responses of the used ions. Campesterol and sitosterol were quantified as trimethylsilyl ethers using the molecular ions m/z 472, and m/z 486, respectively, in relation to the molecular ion m/z 348 of androstanol. The fatty acids were qualified using an external standard mixture and quantified by 19:0 FAME.

title: Aboveground biomass and species abundances estimated in the Jena-Ecotron experiment

description: This dataset contains aboveground biomass and species abundances in the Jena-Ecotron Experiment in 2012. This experiment was conducted in the Montpellier European Ecotron (CNRS, France), an advanced controlled environment facility for ecosystem research, and aimed at understanding the impact of plant species richness (4 vs. 16 species) for ecosystem carbon and water fluxes.The soil monoliths used in this experiment contained plant communities originating from the long- term Jena Experiment (50°57.1' N, 11°37.5' E, 130 m above sea level; mean annual temperature 9.3°C, mean annual precipitation 587 mm) established in May 2002. Twelve plots were selected for the Jena-Ecotron study according to the following criteria: (1) the four functional groups grasses, legumes, small and tall herbs were present, (2) realized species numbers were close to sown species richness, and (3) plots were equally distributed across the experimental field site to account for different soil textures. Large monoliths (2 m² surface area, diameter of 1.6 m, 2 m depth with a weight of 7 to 8 tons) including intact soil and vegetation were excavated in December 2011 and placed in lysimeters. In March 2012, before the start of the vegetation growth, the lysimeters were transported and installed in the Macrocosms platform of the Montpellier European Ecotron.Aboveground biomass production was determined from a final destructive harvest of the Ecotron experiment by clipping the vegetation at ground level on an area of 90 × 55 cm (=0.495m²) in each experimental unit (23-24 July 2012). Samples were sorted to target (= sown) species and weeds (= species not sown into a particular plot). Detached dead plant material was separated. A portion of the species-specific biomass was separated into leaves, shoot and inflorescences. Shoot biomass was dried at 65°C for 48 hours before weighing.
description: There are two types of missing values contained in datasets from the Jena Experiment. Empty cells represent missing values that result from the design of the experiment. Empty cells result when the respective value does not occur in the design and could thus not be measured. For example, in the case of species-specific biomass cells are left blank, when the species was not sown in the respective plot. Missing values that resulted from methodological problems, sampling errors, or lost samples/data are marked with "-9999".This dataset is part of a collection of measurements of the Jena-Ecotron Experiment, which was part of the Jena Experiment.
