Supplementary paleomagnetic data to: “Paleomagnetism in the Pannonian; Problems, Pitfalls, and Progress in using iron sulphides for magnetostratigraphy”

Nick A. Kelder, Karin Sant, Gijs A. van Dijk, Ymke Z. Lathouwers, Mark J. Dekkers, Wout Krijgsman, Imre Magyar & Orsolya Sztanó
This dataset contains the paleomagnetic supplementary material to the article Kelder et al. (subm.), which presents a magnetostratigraphic correlation of Late Miocene lacustrine sediments based on multi-polarity greigite. The multi-polarity is visible in most thermal paleomagnetic results (Zijderveld diagrams) by antipodal high and medium temperature components, while only one magnetic component was visible in the alternating field demagnetization diagrams. Based on this complex behavior, a tailored demagnetization approach was developed to allow for reliable magnetostratigraphic...

Dirk Hoffmeister
This dataset of an orthophoto and digital elevation model is derived from imagery captured by an unmanned aerial vehicle (type: DJI Phantom 4) of the zebra stripe area PP1, Paposo Fault, Chile.

Data supplement to: Laser ablation in situ silicon stable isotope analysis of phytoliths

Daniel A. Frick, Jan A. Schuessler, Michael Sommer & Friedhelm von Blanckenburg
Silicon is a beneficial element for many plants, and is deposited in plant tissue as amorphous bio-opal (phytoliths). The biochemical processes of uptake and precipitation induce isotope fractionation: the mass-dependent shift in the relative abundances of the stable isotopes of silicon. At the bulk scale, the silicon isotope composition reported as δ30Si span from -2 to +6 ‰. To further constrain these variations, at the scale of individual phytolith fragments we applied in situ femtosecond...

A global gridded data set on tillage

Vera Porwollik, Susanne Rolinski & Christoph Müller
Tillage is a central element in agricultural soil management and has direct and indirect effects on processes in the biosphere. Effects of agricultural soil management can be assessed by soil, crop, and ecosystem models but global assessments are hampered by lack of information on type and spatial distribution. This dataset is the result of a study on global classification of tillage practices and the spatially explicit mapping of crop-specific tillage systems for around the year...

It also provides a unique...

CA1985: A global approximation of irrigation dam command areas commissioned since 1985

Philippe Rufin, Christian Levers, Matthias Baumann, Jonas Jägermeyr, Tobias Krueger, Tobias Kuemmerle & Patrick Hostert
The spatial distribution of irrigation dam benefits is poorly understood at the global scale due to a scarcity of spatial information on irrigation dam command areas. Several studies aimed at mapping irrigated lands globally, but the spatially explicit attribution of irrigated lands to dams has rarely been undertaken. First approaches attributing changes in agricultural production to dams were based on aggregated areal units, such as administrative districts (Duflo and Pande, 2007), or watershed boundaries (Strobl...

Landscape Response to the Mw7.9 Gorkha Earthquake

Christoff Andermann, Christoph Sens-Schönfelder & Jens Turowski
Strong earthquakes cause transient perturbations of the near Earth’s surface system. These include the widespread landsliding and subsequent mass movement and the loading of rivers with sediments. In addition, rock mass is shattered during the event, forming cracks that affect rock strength and hydrological conductivity. Often overlooked in the immediate aftermath of an earthquake, these perturbations can represent a major part of the overall disaster with an impact that can last for years before restoring...
