Weber, Tobias • Thomas, Maik
Abstract: These data are supplementary material to the manuscript "Influence of ocean tides on the general ocean circulation in the early Eocene" (T. Weber, M. Thomas, Paleoceanography, http://doi.org/10.1002/2016PA002997). It contains atmospheric and oceanic variables as simulated by the coupled atmosphere-ocean model ECHAM5/ MPIOM for the early Eocene (55 million years ago) and a pre-industrial simulation representing climate conditions at 1850 AD. Simulations are performed without and with tidal forcing of the ocean. The files are available in the zip folder in NetCDF and .txt formats (subfolder MHT). An overview on the available files and their content is given in the README.

Abstract: The observation of the present-day deformation of the Earth's surface with high spatial and temporal resolution makes up a major part of the Integrated Plate Boundary Observatory Chile (IPOC, www.ipoc-network.org). For this purpose, continuously recording GPS stations were installed in Northern Chile since end of 2002. Eleven of IPOC stations (PB01 – PB11) are equipped with permanent recording GPS receivers (TOPCON GB-1000). They continuously measure at sampling rates of both, 1 second and 30 second. The GPS data are archived and processed in GFZ Potsdam. Detailed information about data availability, metadata and site descriptions can be found at: https://kg3-dmz.gfz-potsdam.de/gnss/GFZPBOCGPS. More description about the Integrated Plate Boundary Observatory Chile (IPOC) can be found at the IPOC Website (http:/ipoc-network.org/observatory/gps/gps-at-ipoc). The Survey Mode GPS data in the IPOC Region was published by Moreno et al. (2017).

Abstract: This data set comprises XRF (89 samples) and ICP-AES/ICP-MS (12 samples) major and trace element geochemistry of melt-bearing impact breccia (suevite) samples of the research drill core FBN 73 of the Ries impact crater in Southern Germany. The 1,206 m deep drilling in the central part of the Ries impact crater, carried out in 1973 (Bayerisches Geologisches Landesamt 1974), provided insights into the origin and distribution of suevite and into the development of the post-impact Ries lake with redeposited suevitic sediments at its base (Stöffler et al. 2013). The suevite is divided into five sequences, (1) dike suevite 1186-602 m, (2) melt-rich suevite 602-525 m, (3) melt-rich suevite 525-331 m, (4) graded suevite 331-314 m, and (5) reworked suevite 314-257 m (Stöffler et al., 2013 and references therein). The drill core FBN 73 is stored and accessible at the Zentrum für Rieskrater- und Impaktforschung Nördlingen (Centre for Ries Crater Impact Research, ZERIN) and supplies the best available complete profile through the Ries crater suevite. The data are supplementary material to Siegert et al. (2017, http://doi.org/10.1130/G39198.1) and are supplemented by geochemical data of crystalline target lithologies of the Ries impact crater (Schmitt et. al, 2017; http://doi.org/10.5880/fidgeo.2017.001). Averages of two consecutive melt-rich and melt-poor suevite samples are plotted in Siegert, et al. (2017). More information about sample preparation, methodology as well as detection limits, standards used and precision expectations are given in the Explanatory File.

Abstract: This data set comprises major (XRF) and trace (XRF, ICP-MS, ICP-AES) element geochemistry of 185 samples of crystalline target lithologies of the Nördlinger Ries impact crater in Southern Germany. The sample set was originally collected by D. Stöffler for the investigation of shock metamorphism and Schmitt and Siebenschock for a research project on the occurrence of impact diamonds in the Nördlinger Ries crater. The data are supplementary material to Siegert et al. (2017, http://doi.org/10.1130/G39198.1) and are supplemented by by geochemical data of melt-bearing impact breccia (suevite) from the research drill core FBN 73 of the Ries impact crater (Siegert et al., 2017; http://doi.org/10.5880/fidgeo.2017.002. More information about sample preparation, methodology and precision expectations are given in the Explanatory File. Repository samples and thin sections are available for more or less the whole sample set of Stöffler and selected samples from Schmitt and Siebenschock, and are stored in the impactite collection of the Museum für Naturkunde Berlin.

Abstract: The dataset is composed of hyperspectral imagery acquired during airplane overflights on May 10th, 2011, June 27th, 2011 and May 24th, 2012 consisting of 367 and 368 spectral bands, respective-ly, ranging from VIS to SWIR (400 - 2500 nm) wavelength regions. The hyperspectral image data was acquired in the framework of the EnMAP preparation project HyLand (Hyperspectral remote sensing for the assessment of crop and soil parameters in precision farming and yield estimation). Within the project, innovative techniques were developed to derive crop and soil parameters from hyper-spectral remote sensing and terrestrial laser scanning data, which served as input parameters for novel yield estimation models.
The Environmental Mapping and Analysis Program (EnMAP) is a German hyperspectral satellite mission that aims at monitoring and characterizing the Earth’s environment on a global scale. EnMAP serves to measure and model key dynamic processes of the Earth’s ecosystems by extract-ing geochemical, biochemical and biophysical parameters, which provide information on the status and evolution of various terrestrial and aquatic ecosystems. In the frame of the EnMAP preparatory phase, pre-flight campaigns including airborne and in-situ measurements in different environments and for several application fields are being conducted. The main purpose of these campaigns is to support the development of scientific applications for EnMAP. In addition, the acquired data are input in the EnMAP end-to-end simulation tool (EeteS) and are employed to test data pre-processing and calibration-validation methods. The campaign data are made freely available to the scientific community under a Creative Commons Attribution-ShareAlike 4.0 International License. An overview of all available data is provided in in the EnMAP Flight Campaigns Metadata Portal (http://www.enmap.org/?q=flightbeta).

Abstract: The proxy record is derived from stalagmite YOK-I from the Yok Balum Cave, Belize. Stalagmite YOK-I was collected in June 2006, ca. 160 m from the western cave entrance. Carbonate was actively precipitating on the tip of this 606.9-mm-long stalagmite when it was collected. The stable isotope climate record covers only the upper 415 mm, while the lower stalagmite section is less suitable for stable isotope studies and was not included in this investigation. Over 4,200 δ18O and δ13C measurements were performed on the upper 415 mm of YOK-I and dated between 40 BC and 2006 AD. The samples were continuously milled at 0.1 mm increments and, depending on growth rate changes in YOK-I, the temporal resolution of the isotopic data fluctuates from 0.01 and 3.68 yrs/0.1 mm, with an average resolution of 0.49 yrs/0.1 mm. Earlier versions of the dataset have been published at the NOAA palaeoclimate data server using a slightly different chronology (Kennett et al., Science 2012, DOI:10.1126/science.1226299). In the study of Ridley et al. (Nat Geo 2015, DOI:10.1038/ngeo2353), we have tuned the chronology of YOK-I with the more precise one of the stalagmite YOK-G. These new data is provided as version 2 in the files YOK-I_d18O_v2.csv (for δ18O) and YOK-I_d13C_v2.csv (for δ13C), consisting of 4047 isotope measurements. Kernel filtering was applied to resample the time series to equidistant annual resolution (Smirnov et al, Sci Rep XXX, DOI: XXX), covering the time span from 15 BC to 2005 AD, resulting in 2021 data values. These filtered versions of the data are provided as files YOK-I_d18O_kernelfiltered.csv and YOK-I_d13C_kernelfiltered.csv. In all files, the first column consists of the age (in yr AD) and the second column (separated from the first column by a semicolon) is the corresponding isotope value (in permil VPDB). The data is presented as four .csv files in a .zip folder.

Abstract: The growing number of paleoenvironmental data, GIS-based analyses and modelling allows us to produce PaleoMaps for a given area. However, the „translation“ of paleoenvironmental information in maps is even more complex, than producing maps as an illustration of the present. The CRC 806 “Our Way to Europe” provides the background to study the culture-environment interaction and human mobility in the Late Quaternary. Northeastern Africa during the Last Interglacial is thereby an important region and timespan. From this point, a first conceptual design for a PaleoMap of Egypt for the time about 125 ka ago is presented.
