Antarctic ice sheet expansions in the Middle Miocene and Pliocene
(Univ. Bremen, 2008)
This study focuses on the interactions between climate and ice sheets in order to obtain a better understanding of the processes involved. Two periods in the geological past are explored; the Middle Miocene and the ...
Modeling Net Ecosystem Exchange for Grassland in Central Kazakhstan by Combining Remote Sensing and Field Data
- Remote Sensing
Carbon sequestration was estimated in a semi-arid grassland region in Central Kazakhstan using an approach that integrates remote sensing, field measurements and meteorological data. Carbon fluxes for each pixel of 1 × ...
Influence of shape fabric and crystal texture on marble degradation phenomena: simulations
- Environmental Earth Sciences
Microstructure-based finite element simulations were used to study the influence of grain shape fabric and crystal texture on thermoelastic responses related to marble degradation phenomena. Calcite was used as an illustrative ...
Über Umfang und Stellung des Rhaet
- Newsletters on stratigraphy
The duration and position of the Rhaetian Stage are di scussed. With the recognition of Rhabdoceras suessi - up to now the index species of the Upper Norian (Sevatian) - in one of the Alpine type sections of the Rhaetian, ...
Designing Iron-Amended Biosand Filters for Decentralized Safe Drinking Water Provision
- CLEAN - Soil, Air, Water
There are ongoing efforts to render conventional biosand filters (BSF) more efficient for safe drinking water provision. One promising option is to amend BSF with a reactive layer containing metallic iron (Fe0). The present ...
Microbialite formation in seawater of increased alkalinity, Satonda Crater Lake, Indonesia - Reply
- Journal of sedimentary research
Our paper (Arp et al. 2003) revises previous studies of Kaz´mierczak and Kempe (1990, 1992), Kempe and Kaz´mierczak (1990a, 1990b, 1993), and Kempe et al. (1996, 1997) on Lake Satonda reefs with regard to biofilm calcification ...
Hydrated sub-arc mantle: a source for the Kluchevskoy volcano, Kamchatka/Russia
- Earth and Planetary Science Letters
Oxygen isotope ratios of olivine and clinopyroxene phenocrysts from the Kluchevskoy volcano in Kamchatka have been studied by CO2 and ArF laser techniques. Measured δ18O values of 5.8–7.1‰ for olivine and 6.2–7.5‰ for ...
A chronological and palaeoenvironmental re‐evaluation of two loess‐palaeosol records in the northern Harz foreland, Germany, based on innovative modelling tools
The continuing development of analytical methods for investigating sedimentary records calls for iterative re‐examination of existing data sets obtained on loess‐palaeosol sequences (LPS) as archives of palaeoenvironmental ...
Structural Elucidation of α-Cyclodextrin-Succinic Acid Pseudo Dodecahydrate: Expanding the Packing Types of α-Cyclodextrin Inclusion Complexes
This paper reports a new packing type of -cyclodextrin inclusion complexes, obtained here with succinic acid under low-temperature crystallization conditions. The structure of the 1:1 complex is characterized by heavy ...
Analogue experiments of salt flow and pillow growth due to basement faulting and differential loading
- Solid Earth
Salt flow in sedimentary basins is mainly driven by differential loading and can be described by the concept of hydraulic head. A hydraulic head in the salt layer can be imposed by vertically displacing the salt layer ...
