title: Soil erosion rate maps for Peru

description: Quantifying soil erosion rates (ERs) in developing countries is necessary to accomplish the Goal 15 of the UN 2030 Agenda for Sustainable Development and is relevant to meet the technical challenges of future hyperresolution models. This study proposes using the RUSLE model on the basis of the Generalized Likelihood Uncertainty Estimation (GLUE) methodology to estimate ERs at country scale for developing countries, which commonly exhibit spatio-temporal limitations/lack of groundbased measurements or field relations potentially inducing high uncertainty in the estimates of the R and C factors. In this context, ERs are calibrated with area-specific sediment yield data and global soil erosion model outputs. The method is successfully applied to Peru, and subsequently 5-km resolution ER maps are obtained for the years 1990, 2000, and 2010 which suggest that the steady increase of soil erosion rates are mainly induced by anthropogenic controls (e.g. changes in land use). In the light of our results, we believe that the method has the potential to be used as a standard method to estimate ERs and provide decision makers for an objective information to better manage soil resources in developing countries.

title: Geomorphological and geocryological maps of the Zackenberg Valley, NE Greenland (ArCGIS Map Package)

description: In High Arctic northern Greenland, future responses to climatic changes are poorly understood on a landscape scale. Here, we present a study of the geomorphology and cryostratigraphy in the Zackenberg Valley in NE Greenland (74°N) containing a geomorphological map and a simplified geocryological map, combined with analyses of 13 permafrost cores and two exposures. Cores from a solifluction sheet, alluvial fans, and an emerged delta were studied with regards to cryostructures, ice and total carbon contents, grain size distribution, and pore water electrical conductivity; and the samples were AMS 14C dated. The near-surface permafrost on slopes and alluvial fans is ice rich, as opposed to the ice-poor epigenetic permafrost in the emerged delta. Ground ice and carbon distribution are closely linked to sediment transport processes, which largely depend on lithology and topography. Holocene alluvial fans, covering 12% of the lowermost hillslopes, represent paleoenvironmental archives. During the contrasting climates of the Holocene, the alluvial fans continued to aggrade - through the warmer early Holocene Optimum, the colder late Holocene, and the following climate warming - and by 0.45 mm a- 1, on average. This is caused by three factors: sedimentation, ground ice aggradation, and vegetation growth and is reflected by AMS 14C dating and continuously alternating cryostructures. Highly variable sedimentation rates in space and time at the alluvial fans have been detected. This is also reflected by alternating lenticular and microlenticular cryostructures indicating syngenetic permafrost aggradation during sedimentation with suspended and organic-matrix cryostructures indicating quasi-syngenetic permafrost aggradation in response to vegetation growth in periods with reduced or no sedimentation. Over time, this causes organic matter to become buried, indicating that alluvial fans represent effective carbon sinks that have previously been overlooked.

title: Original data of seafloor crustal deformation along the subduction zones around Japanese Islands

description: Since the mid-1990s, we (Hydrographic and Oceanographic department, Japan Coast Guard) have been developing the combined Global Navigation Satellite System-Acoustic ranging (GNSS-A) technique for realizing seafloor geodesy. This technique allows us to collect time series of seafloor crustal deformation. In this dataset, we published our original data obtained from 2001 to Aug. 2017. Our data can be used to investigate several seismological phenomena along the subduction zones around Japan, namely the Nankai Trough, Sagami Trough and Japan Trench. These regions are globally important places in geodesy and seismology and are also suitable for comparison with other geophysical datasets.

title: Semi-natural forest ecosystem types of Germany and the Kellerwald National Park (Hesse, Germany), link to files

description: Spatial data of current semi-natural forest ecosystem types of Germany and the Kellerwald National Park (Hesse, Germany) are presented. Ecosystem types were classified as entities characterized by certain homogeneity of significant features of their structures and functions. Accordingly, ecosystem types were categorized using data collected for 21600 forest sites across Germany during the years 1961-1990. Focusing on forest ecosystems, two maps of Current semi-natural Ecosystem Types (EsT) were derived from available data: (1) EsT of Germany (1 : 500,000 equivalent scale, representing the time period 1991-2010) and (2) EsT in the Kellerwald National Park (1: 25,000 equivalent scale, 2001-2010).

title: Soil Water Infiltration Global (SWIG) Database

description: In this database we present and analyze a global database of soil infiltration measurements, Soil Water Infiltration Global (SWIG) database, for the first time. In total, 5023 infiltration curves were collected across all continents. These data were either provided and quality checked by the scientists who performed the experiments or they were digitized from published articles. Data from 54 different countries were included in the database with major contributions from Iran, China, and USA. In addition to its global spatial coverage, the collected infiltration curves cover a time span of research from 1976 to late 2017. In addition to infiltration data, basic information of the measurement location, the measurement method, soil properties, and land use were collected, which makes the database valuable for the development of pedo-transfer functions for estimating soil hydraulic properties, for the evaluation of infiltration measurement methods and for developing and validating infiltration models. Soil textural information (clay, silt, and sand content) is available for 3842 out of 5023 infiltration measurements (~76%) covering nearly all soil USDA textural classes except for the sandy clay and silt classes. Information on the land use is available for 76 % of experimental sites with agricultural land use as the dominant type (~40%). We are convinced that the SWIG database will allow for a better parametrization of the infiltration process in land surface models and for testing infiltration models. All collected data and related soil characteristics are provided online in *.xlsx and *.csv formats for reference, and we add a disclaimer that the database is for use by public domain only and can be copied freely by referencing it. Data quality assessment is strongly advised prior to any use of this database. New data are welcomed to extend/update SWIG.

title: Wave height to water depth ratios for coral reef flats from different coral reef surf zones

description: Wave breaking and transformation on coral reef flats is an important process protecting tropical coastlines and regulating the energy regimes of coral reefs. However, the high hydraulic roughness, shallow water, and steep bathymetries of coral reefs may confound common surf zone assumptions, such as a depth-limited and saturated surf zone with a constant wave height to water depth ratio (γ). Here, we examine wave transformation across a coral reef flat, during three separate swell events, on both a time-averaged and a wave-by wave basis. We use the relationship between significant wave height and water depth (γs) to examine the change in surf saturation across the reef flat and compare the measured wave height decay to results of modelled wave energy dissipation in the surf zone. Our results show that γs was not cross-reef constant and varied according to location on the reef flat and local water depth. On average, γs was greatest at the outer reef flat, near the reef crest, and progressively reduced towards the inner reef flat, near the reef lagoon. This was most pronounced in shallow water with large γs values (γs &gt; 0.85) at the outer reef flat and small γs values (γs &lt; 0.1) at the inner reef flat. This indicates that there is an increase in wave energy dissipation in shallow water, most likely due to increased breaker and bed frictional dissipation. The measured wave energy dissipation across the entire reef flat could, on average, be modelled accurately; however, this required location specific calibration of the free parameters, the wave friction factor (fw) and γ, and further suggests that there is no value for either parameter that is universally applicable to coral reef flats. Despite model calibration inaccuracies were still observed, primarily at the outer reef flat. These inaccuracies reflected the observed cross-reef variation of γ on the reef flat and potentially the limitations of random wave breaker dissipation models in complex surf zones. Our results have implications for the use of wave energy dissipation models in predicting breaker dissipation and subsequent benthic community change on coral reef flats, and uggest that careful consideration of the free parameters in such models (such as fw and γ) is required.

title: Bed surface adjustments to spatially variable flow in low relative submergence regimes, link to supplementary data in MS Excel format

description: In mountainous rivers, large relatively immobile grains partly control the local and reach-averaged flow hydraulics and sediment fluxes. When the flow depth in low relative submergence conditions plunging flow and the highly three-dimensional flow field can cause spatial distributions of bed surface elevations and grain size distributions, therefore, causing a spatially variable sediment transport rate. We conducted a set of experiments to study how the bed surface responds to this spatial variability and in particular the effect relative submergence in the formation of sediment patches around simulated large boulders. Same average sediment transport capacity, upstream sediment supply, and initial bed thickness and grain size distribution were imposed in all experiments. The detailed flow field around the boulders was obtained using a combination of laboratory measurements and a 3D flow model based on the Volume of Fluid technique. The local shear stress field displayed substantial variability and controlled the bedload transport rates and direction in which sediment moved. The divergence in shear stress caused by the hemispheres promoted size-selective bedload deposition, which formed patches of coarse sediment upstream of the hemisphere. Sediment deposition caused a decrease in local shear stress, which combined with the coarser grain size, enhanced the stability of this patch. The region downstream of the hemispheres was largely controlled by a recirculation zone and had little to no change in grain size, bed elevation, and shear stress. The formation, development and stability of sediment patches in mountain streams is controlled by the shear stress divergence and magnitude and direction of the local shear stress field.

description: ur continuous photographic transects (45 to 90 km in extent) were made with deep-towed, wide-angle cameras over the manganese pavement region of the Blake Pla¬teau. The photos indicate that the pavement is covered by discontinuous, mobile sand patches and that zones of transition exist between the pavement and manganese-nodule areas.
description: From 1983 until 1989 NOAA-NCEI compiled the NOAA-MMS Marine Minerals Geochemical Database from journal articles, technical reports and unpublished sources from other institutions. At the time it was the most extended data compilation on ferromanganese deposits world wide. Initially published in a proprietary format incompatible with present day standards it was jointly decided by AWI and NOAA to transcribe this legacy data into PANGAEA. This transfer is augmented by a careful checking of the original sources when available and the encoding of ancillary information (sample description, method of analysis...) not present in the NOAA-MMS database.

title: Towards a new paleotemperature proxy from reef coral occurrences, link to supplementary materialx

description: Global mean temperature is thought to have exceeded that of today during the last interglacial episode (LIG, ~125,000 yrs BP) but robust paleoclimate data are still rare in low latitudes. Occurrence data of tropical reef corals may provide new proxies of low latitude sea-surface temperatures. Using modern reef coral distributions we developed a geographically explicit model of sea surface temperatures. Applying this model to coral occurrence data of the LIG provides a latitudinal U-shaped pattern of temperature anomalies with cooler than modern temperatures around the equator and warmer subtropical climes. Our results agree with previously published estimates of LIG temperatures and suggest a poleward broadening of the habitable zone for reef corals during the LIG.
