title: Dissolved organic carbon in soil solution of the Jena Experiment (Main Experiment, year 2008)

description: This data set contains measurements of dissolved organic carbon in samples of soil water collected from the main experiment plots of a large grassland biodiversity experiment (the Jena Experiment; see further details below). In the main experiment, 82 grassland plots of 20 x 20 m were established from a pool of 60 species belonging to four functional groups (grasses, legumes, tall and small herbs). In May 2002, varying numbers of plant species from this species pool were sown into the plots to create a gradient of plant species richness (1, 2, 4, 8, 16 and 60 species) and functional richness (1, 2, 3, 4 functional groups). Plots were maintained by bi-annual weeding and mowing. In April 2002 glass suction plates with a diameter of 12 cm, 1 cm thickness and a pore size of 1–1.6 mm (UMS GmbH, Munich, Germany) were installed in depths of 10, 20, 30 and 60 cm to collect soil solution. The sampling bottles were continuously evacuated to a negative pressure between 50 and 350 mbar, such that the suction pressure was about 50 mbar above the actual soil water tension. Thus, only the soil leachate was collected. Cumulative soil solution was sampled biweekly and analyzed for dissolved organic carbon concentration by a high TOC elemental analyzer (Elementar Analysensysteme GmbH, Hanau, Germany). Samples were analyzed as soon as possible and stored at 4°C if necessary. Often in summer, no free soil solution was available for collection, especially in the upper soil layers. Annual mean values of measured biweekly concentrations of dissolved organic carbon are provided.
description: During summer month soil frequently dries out so that no soil pore water can be collected. Consequently, in these periods no DOC concentrations can be determined and these periods do not contribute to the reported annual means of DOC concentrations. Only in block 2 suction plates were installed in all four depth layers. Suction plates in 30 centimeter depth were installed in block 1, 2, and 3 in 2002. In 2005, additional suctions plates were installed in 20 centimeter depth in block 1, 2, and 3. In block 4, no samples are available because no plates were installed.There are two types of missing values contained in the dataset. Empty cells represent missing values that result from the design of the experiment when the respective value does not occur and thus cannot be measured. Missing values that resulted from methodological problems, sampling errors, or lost samples/data are marked with "-9999".In addition to measurement of dissolved organic carbon in soil solution, measurements of soil carbon (organic, inorganic, and total) determined from dried soil samples are available.This datasets is part of a time series of soil carbon measurements in the Main Experiment since 2002 (doi:10.1594/PANGAEA.848946).

title: Total nitrogen from solid phase in the Jena Experiment (Main Experiment up to 30cm depth, year 2008)

description: This data set contains measurements of total nitrogen from the main experiment plots of a large grassland biodiversity experiment (the Jena Experiment; see further details below). In the main experiment, 82 grassland plots of 20 x 20 m were established from a pool of 60 species belonging to four functional groups (grasses, legumes, tall and small herbs). In May 2002, varying numbers of plant species from this species pool were sown into the plots to create a gradient of plant species richness (1, 2, 4, 8, 16 and 60 species) and functional richness (1, 2, 3, 4 functional groups). Plots were maintained by bi-annual weeding and mowing. Soil sampling and analysis: Stratified soil sampling was performed in April 2008 to a depth of 30 cm. Three independent samples per plot were taken using a split tube sampler with an inner diameter of 4.8 cm (Eijkelkamp Agrisearch Equipment, Giesbeek, the Netherlands). Soil samples were segmented to a depth resolution of 5 cm in the field, giving six depth subsamples per core, and made into composite samples per depth. Sampling locations were less than 30 cm apart from sampling locations in other years. Samples were dried at 40°C. All soil samples were passed through a sieve with a mesh size of 2 mm. Because of much higher proportions of roots in the soil, the samples were further sieved to 1 mm according to common root removal methods. No additional mineral particles were removed by this procedure. Total nitrogen concentration was analyzed on ball-milled subsamples (time 4 min, frequency 30 s-1) by an elemental analyzer at 1150°C (Elementaranalysator vario Max CN; Elementar Analysensysteme GmbH, Hanau, Germany).
description: In 2002 and 2007, measurements of total nitrogen in a depth of up to 1m (depth resolution of 5 cm giving 20 depth subsamples per core) are available. In addition to measurements of total nitrogen determined from dried soil samples, measurement of dissolved nitrogen in soil solution and measurements of mineral nitrogen from KCl-extractions of soil samples are available.This datasets is part of a time series of soil nitrogen measurements in the Main Experiment since 2002 (doi:10.1594/PANGAEA.854372).

title: Mendenhall Glacier basal ice-sediment outcrop samples, 2021

description: We gathered field observations of debris-rich ice layers from an alpine glacier margin to help inform models of glacial sediment transport across landscapes. Basal ice and entrained sediment samples were taken from the margin of Mendenhall Glacier, Juneau, AK, in August 2021. Along the land-terminating margin of the glacier, we identified five representative outcrops of debris-rich ice with obvious stratigraphic layers. Samples were taken in duplicate at intervals from the base of the debris-rich layers to the clean ice above. After removing the outermost layer of sediment, which is typically enriched by surface melt, we weighed the samples in the field, then transported them back to the Sedimentology and Plant Lab at the Institute of Arctic and Alpine Research in Boulder, Colorado. In the lab, samples were freeze-dried to remove the ice fraction, then weighed again to obtain sediment mass, and thus sediment concentration.

title: Planktonic and epibenthic foraminifera oxygen and carbon stable isotope data, sediment weights and sediment geochemistry data for off-splice samples from IODP Site 339-U1387 in the Gulf of Cadiz

description: When generating high resolution paleoceanographic reconstructions for the early to middle Pleistocene sections of Integrated Ocean Drilling Program (IODP) Site U1387, it became obvious that proxy data misfits existed at most splice transitions in the shipboard splice below ~155 mcd. A revised splice was established below Core U1387B-18X based on X-ray fluorescence (XRF) derived element records (e.g., ln(Fe/Ca)) and the stable isotope records obtained for planktonic and benthic foraminifers (Voelker et al., 2018; doi: 10.2204/iodp.proc.339.204.2018). Corrections were needed at most of the splice transitions below Core U1387A-19X with adjustments ranging from a few centimeters to several meters, leading to a corrected meters composite depth (c-mcd) scale. In addition, Core U1387A-33X and sections of Core U1387A-36X were integrated into the revised splice to replace Core U1387C-2R and sections of Core U1387C-5R, respectively. The substitution of Core U1387C-2R with Core U1387A-33X is an option for the intended paleoceanographic research and not essential for lower resolution studies. Since data for samples outside the revised splice sequence will not be included in future publications, we are making the data, in particular of Cores U1387C-2R and U1387C-5R, available, so that it can be used by those working along the shipboard splice or needing such data for other interests. Consequently, this dataset provides the stable isotope data measured in G. bulloides and two epibenthic foraminifera species, the sample's dry weight and sand fraction related data as well total organic carbon, carbonate, C/N and lipid biomarker extraction derived data, where available, for Core U1387C-2R and parts of Core U1387C-5R as well as from a few other samples that are not part of the revised splice sequence.
