The information system PANGAEA provides targeted support for research data management as well long-term archiving and publication. is operated an open access library archiving, publishing, distributing georeferenced from earth environmental sciences. It focuses on observational experimental data. Citability, comprehensive metadata descriptions, interoperability of metadata, a high degree structural semantic harmonization the inventory commitment hosting institutions ensures usability...
The evaporation method is frequently used for simultaneous determination of soil water retention and hydraulic conductivity relationships. Tension measured at two depths within a short column as evaporates from its surface. Water content flux are determined by weighing the column. Tensions, contents, fluxes to derive curve unsaturated function. measurement range conventional procedure limited on wet end inability pressure transducers accurately register very small tension differences. Hence,...
Abstract Knowledge of hydraulic functions is required for various hydrological and plant‐physiological studies. The evaporation method frequently used the simultaneous determination unsaturated soil samples, i.e. , water‐retention curve hydraulic‐conductivity function. All methodic variants suffer from limitation that can only be determined to a mean tension ≈ 60 kPa. This caused by limited measurement range tensiometers typically 80 kPa on dry end. We present new, cost‐ time‐saving approach...
Abstract Since about 25 years, we have measured the unsaturated hydraulic conductivity function and water retention curve with evaporation method of more than 1500 mineral organic soils samples. From this data base, 104 representative samples varying texture dry bulk density were selected temporal dynamics basic values (mass or loss, respectively, tension change over time) was analyzed. With exception sand, loss per time interval constant in all other during measuring range between 0 60 kPa....

The Scholix Framework (SCHOlarly LInk eXchange) is a high level interoperability framework for exchanging information about the links between scholarly literature and data, as well datasets. Over past decade, publishers, data centers, indexing services have agreed on implemented numerous bilateral agreements to establish bidirectional research literature. However, because of considerable differences inherent these many agreements, there very limited various solutions. This situation fueling...
Abstract Aim of the study was evaluation present state and further development drought risk to agricultural sites in Northeast (NE) Central Germany consideration climate changes. Based on Medium Scale Agricultural Site Map, soil‐hydrological data were derived for heterogeneous soil areas. They refer landscapes NE characterized by low precipitation, marked spatial heterogeneity, a high share hydromorphic soils.

This paper provides information about a novel approach of rating agricultural soil quality (SQ) and crop yield potentials consistently over range spatial scales. The Muencheberg Soil Quality Rating is an indicator-based straightforward overall assessment method SQ. It framework covering aspects texture, structure, topography climate which based on 8 basic indicators more than 12 hazard indicators. Ratings are performed by visual methods evaluation. A field manual then used to provide ratings...
Abstract In general, soils and their pore size systems are assumed to be rigid during the loss of water on drying. reality, it is not case for most soils, especially with high quantities clay or organic matter. As a result shrinking, there changes in bulk density, porosity, distribution, hydraulic properties these soils. Currently, only few methods enable shrinkage behavior soil samples determined while simultaneously quantifying corresponding properties. Either need proprietary software...

The number of studies investigating the effects ocean acidification on marine organisms and communities increases every year. Results are not easily comparable since carbonate chemistry ancillary data always reported in similar units scales calculated using sets constants. To facilitate comparison, a compilation hosted by PANGAEA Data Publisher was initiated European Network Excellence for Ocean Ecosystems Analysis (EUR-OCEANS) first large-scale Project Acidification (EPOCA) 2008. It has...
Core Ideas We performed time series analysis of existing large soil moisture data sets. Observed behavior was decomposed into respective contributions single processes. Considering input signal transformation instead mass flux considerations. Our approach opens many new possibilities to analyze complex system behavior. Soil is the essential control water and energy dynamics at arable sites. Time reflect interplay various processes, each which influences overall dynamics. In this study we...
