Stable Biological Production in the Eastern Equatorial Pacific Across the Plio‐Pleistocene Transition (∼3.35–2.0 Ma)
; Ho, S. Ling; Meckler, A. Nele; Pross, Jörg; Fiebig, Jens; ; (
Upwelling within the Eastern Equatorial Pacific (EEP) Ocean is a key factor for the Earth's climate because it supports >10% of the present‐day biological production. The dynamics of upwelling in the EEP across the ...
Investigating the release of coprecipitated uranium from iron oxides
; Schöner, A.; Dienemann, H. (
The removal of uranium (VI) from zerovalent iron permeable reactive barriers and wetlands can be explained by its association with iron oxides. The long term stability of immobilized U is yet to be addressed. The present ...
Changes in the Dust-Influenced Biological Carbon Pump in the Canary Current System: Implications From a Coastal and an Offshore Sediment Trap Record Off Cape Blanc, Mauritania
; ; ; ; ; ; ; ; ; ; (
Long-term data characterizing the oceans' biological carbon pump are essential for understanding impacts of climate variability on marine ecosystems. The “Bakun upwelling intensification hypothesis” suggests intensified ...
Intratest Variations in Trace Element Composition of Amphistegina lessonii Using Femtosecond‐Laser Ablation‐ICP‐Mass Spectrometry: A Field Study From Akajima, Okinawa Prefecture, Japan
; ; Singh, Asmita; Saraswati, Pratul Kumar; ; ; Stoll, Brigitte; Haug, Gerald H. (
Amphistegina are common larger benthic foraminifer in coral reefs, with a nearly circumtropical distribution, and are major contributors to the CaCO3 budget of shallow marine environments. The family Amphisteginidae is ...
Water in garnet of garnetite (metarodingite) and eclogite from the Erzgebirge and the Lepontine Alps
; Gose, Jürgen (
Little is known about water in nominally anhydrous minerals of orogenic garnet peridotite and enclosed metabasic rocks. This study is focused on peridotite-hosted eclogite and garnetite (metarodingite) from the Erzgebirge ...
Elemental iron (Fe0) for better drinking water in rural areas of developing countries
; Woafo, P. (
Many of the reasons behind the anthropogenic contamination problems in rural environments of developing countries lie in changes in the traditional way of life and the ignorance on the toxic potential of introduced ...
Entwicklung mineralogischer Färbetechniken und ihre Anwendung auf spezifische Betonphasen zur Analyse der Zusammensetzung von zementgebundenen Baustoffen
(Univ. Halle (Saale), 2007)
Ziel der Arbeit war die Entwicklung neuer Methoden zur Analyse der Rezeptur, des Gefüges und der Alterung von zementgebundenen Baustoffen. Dazu wurden mineralogische Färbemethoden so weiterentwickelt, dass sie auf Betonproben ...
Carbonates from the ancient world's longest aqueduct: A testament of Byzantine water management
; ; ; ; Mertz‐Kraus, Regina (
The fourth‐ and fifth‐century aqueduct system of Constantinople is, at 426 km, the longest water supply line of the ancient world. Carbonate deposits in the aqueduct system provide an archive of both archaeological ...
Association of S-type and I-type granitoids in the Neoproterozoic Cameroon orogenic belt, Bafoussam area, West Cameroon - geology, geochemistry and petrogenesis
(Univ. Würzburg, 2005)
Die Region Bafoussam im westlichen Kamerun ist Teil des "Cameroon Neoproterozoic orogenic belt" (nördlich des Kongo Kratons), welcher zum "Central African Fold Belt" (CAFB)gehört. Die Entstehung des CAFB hängt ...
