Methane ebullition, sedimentation rates, organic matter quality and environmental parameters at small and shallow temperate Lake Windsborn, Germany in 2017 and 2018

To determine spatiotemporal variability of methane (CH4) ebullition and its drivers, we measured CH4 ebullition rates, sedimentation rates and characteristics of the sedimented material, sediment chemical and physical characteristics and environmental parameters at Lake Windsborn in 2017 and 2018. Measurements of CH4 ebullition were conducted bi-weekly from May to October 2017 and April to November 2018. Sedimentation rates were measured in 2018 in four-week intervals. Characteristics of the sedimented material were measured in 2017 and 2018. Sediment characteristics were measured in November 2017, spring 2018 and August 2019. Meterological parameters (temperature and air pressure) were constantly measured from a floating platform in the lake center.

Biogeochemical parameters in sediment cores from MSM 16/1 August 2010 Baltic Gas

The samples presented here were collected with the intent to understand methane cycling in the sediments of the Baltic Sea as part of the BALTIC GAS project funded by the European Community's Seventh Framework Programme (FP/2007-2013) under grant agreement n° 217246 made with the joint Baltic Sea Research and Development programme BONUS. Sediment cores from the Baltic Sea were collected and serve as events in this archive. The events took place in Mecklenburg Bay, Arkona Basin, Bornholm Basin, Gotland Basin, Bothnian Sea, and Bothnian Bay. Ninety events took place between July 31- August 15, 2010 aboard RV Maria S. Merian cruise MSM16/1. From the sediment cores, porewater was extracted and analyzed for sulfate, chloride, ammonium, major ions (barium, calcium, potassium, magnesium, sodium), hydrogen sulfide, and dissolved inorganic carbon concentrations. Dissolved inorganic carbon was also measured for stable carbon isotope ratios. Sediment plugs were collected for measuring concentrations and stable carbon isotope ratios of methane. Sulfate reduction rates were also measured on sediment cores. Bulk sediment was then analyzed for total organic carbon and nitrogen content, along with stable carbon and nitrogen ratios on total organic matter. Sediments were also measured for wet bulk density and water content of wet mass, from which porosity was calculated.

Soil physical and hydraulic properties along two chronosequences of proglacial moraines

The data set ": Soil physical and hydraulic properties along two chronosequences of proglacial moraines" consists of several individual files in tabstop delimeted text format. The data set contains soil physical data from two chronosequences of moraines in glacier forefields in the central Alps, Switzerland. Aim of the study was to investigate the impact of age and parent material on soil physical characteristics. At the forefield of the Stone Glacier the moraines developed from silicate parent material (S) and at the forefield of the Griessfirn from calcareous parent material (C). At each forefield disturbed and undisturbed soil samples were collected from four moraines of different ages and porosity, bulk density, particle size distribution, gravel content, ignition loss, retention curves and unsaturated hydraulic conductivity curves were determined. Per moraine, three sampling sites were identified based on the level of vegetation complexity [low, medium, high] (for details on this vegetation classification see Maier et al., 2019). Two sampling locations spaced 3 to 4 m apart were selected per vegetation complexity at each moraine. These different sampling locations are identified in the files as location 1 and 2. Data sets from the moraines developed from silicate parent material are marked with S and data from the moraines with calcareous parent material are marked with C. For the C forefield bulk density, porosity and ignition loss are listed in a single file. For the S location the ignition loss data is listed in a separate file from the bulk density and porosity data. In each file the sample type, the sample volume, the sample number, the moraine age, the sampling depth, and the level of vegetation complexity are provided. The particle size distributions of the fine earth and the gravel content are also listed in individual files. Again, the sample number, moraine age, vegetation complexity, sampling depth and sampling location are noted in the files. For the retention curves and the unsaturated hydraulic conductivity curves, two files exist for each curve and glacier forefield, which are named accordingly with the glacier forefield identification and type of curve. An overview file for each glacier forefield contains a list with the sample number, moraine age, sampling depth, vegetation complexity and sampling location. The other two files per curve contain the lab measurements. For the retention curve data, the sample numbers link the pressure head [cm] values provided in one file to the corresponding volumetric water content [-] values provided in the other file. The same applies to the hydraulic conductivity curve where the sample number now links the unsaturated hydraulic conductivity [cm/h] to the corresponding pressure head [cm].

KTB Borehole Measurements: Gravimetry inside the borehole of the German Continental Deep Drilling Program

KTB Borehole Measurements Data Gravimetry inside the borehole Extensive borehole measurements were performed during the active drilling phase of the KTB pilot and main hole. The data report STR 21/03 KTB Borehole logging data contains the full description of the logging data given here. Please read it thoroughly to avoid inappropriate or wrong use of the data. The KTB borehole measurement data files contain the final processed versions of logging data from the two KTB boreholes: • KTB-Oberpfalz VB (KTB Vorbohrung/Pilot Hole or KTB-VB) • KTB-Oberpfalz HB (KTB Hauptbohrung/Main Hole or KTB-HB). Here only the acronyms KTB-VB and KTB-HB are used. In total there are 145 data files from the KTB-VB and 239 data files from the KTB-HB. All logs were run in open hole unless noted otherwise (see the file header). The maximum logging depth was 4001 m in the KTB-VB and 9085 m in the KTB-HB. The files of the Gravimetry measurements contain data from measurements made with a Lacoste-Romberg gravity meter sonde from the company EDCON, USA. The gravimetry logs are not depth corrected to the reference GR because the sonde had no GR sensor. The data are provided in ASCII format. Detailed descriptions are provided in the associated data report (STR 21/03, Kueck et al., 2021) and the KTB Borehole Measurements Catalog. Acknkowledgements: The GFZ German Research Centre for Geosciences, Potsdam, Germany, as successor of the KTB Project Management provides the logging data, which were obtained under grants RG8604, RG8803 and RG 9001 of the Federal Ministry of Research and Technology of Germany.

KTB Borehole Measurements: Magnetic Susceptibility and Magnetic Field of the German Continental Deep Drilling Program

KTB Borehole Measurements Data Magnetic Susceptibility and Magnetic Field Extensive borehole measurements were performed during the active drilling phase of the KTB pilot and main hole. The data report STR 21/03 KTB Borehole logging data contains the full description of the logging data given here. Please read it thoroughly to avoid inappropriate or wrong use of the data. The KTB borehole measurement data files contain the final processed versions of logging data from the two KTB boreholes: • KTB-Oberpfalz VB (KTB Vorbohrung/Pilot Hole or KTB-VB) • KTB-Oberpfalz HB (KTB Hauptbohrung/Main Hole or KTB-HB). Here only the acronyms KTB-VB and KTB-HB are used. In total there are 145 data files from the KTB-VB and 239 data files from the KTB-HB. All logs were run in open hole unless noted otherwise (see the file header). The maximum logging depth was 4001 m in the KTB-VB and 9085 m in the KTB-HB. The Magnetic Susceptibility (MSUS) and Magnetic Field data files comprise data from a magnetic susceptibility sonde from the university of Munich, and two magnetometer sondes from the university of Braunschweig (FML-BS) and of Schlumberger (GPIT). MSUS was only run in the KTB-VB. The Braunschweig magnetometer was run in both KTB boreholes and the GPIT only in the KTB-HB. The MSUS log and the magnetic field log in the KTB-VB are not depth corrected to the reference GR because the sondes had no GR sensor. Both types of magnetic field logs in the KTB-HB are depth corrected to the reference GR. The data are provided in ASCII format. Detailed descriptions are provided in the associated data report (STR 21/03, Kueck et al., 2021) and the KTB Borehole Measurements Catalog. Acknkowledgements: The GFZ German Research Centre for Geosciences, Potsdam, Germany, as successor of the KTB Project Management provides the logging data, which were obtained under grants RG8604, RG8803 and RG 9001 of the Federal Ministry of Research and Technology of Germany.
