How well do sediment indicators record past climate? An evaluation using annually laminated sediments
The reliability of paleoclimatic inferences from lake-sediment records rests on the understanding of how various sediment indicators respond to environmental changes. Despite the recent proliferation of paleoclimatic records, only a limited number of studies have rigorously evaluated potential indicators by comparing lake-sediment records with instrumental weather data. We analyzed annually lam...
متن کاملAspects of carbon isotope biogeochemistry of late Quaternary sediments from the Marmara Sea and Black Sea
The Marmara Sea is situated between the world’s largest permanently anoxic basin, the Black Sea, and an enclosed marginal sea, the Aegean Sea, which experienced quasi-periodic sapropel deposition since Miocene time. It is connected to the Black Sea and the Aegean Sea through the Straits of Bosphorus and Dardanelles, respectively. Sapropel M1, which contains from 1 to 2% total organic carbon, wa...
متن کاملPalaeoclimatic interpretation of high-resolution oxygen isotope profiles derived from annually laminated speleothems from Southern Oman
High-resolution stable isotope profiles of three contemporaneously deposited stalagmites from a shallow cave in Southern Oman provide an annually resolved record of Indian Ocean monsoon rainfall variability for the past 780 years. Uranium-series age dating and counts of annual growth bands enable an excellent age calibration. Although modern speleothems do not grow in perfect isotopic equilibri...
متن کاملMiocene honey bees from the Randeck Maar of southwestern Germany (Hymenoptera, Apidae)
The Miocene Randeck Maar (southwestern Germany) is one of the only sites with abundant material of fossil honey bees. The fauna has been the focus of much scrutiny by early authors who recognized multiple species or subspecies within the fauna. The history of work on the Randeck Maar is briefly reviewed and these fossils placed into context with other Tertiary and living species of the genus Ap...
متن کاملPetrology and geochemistry of annually laminated stalagmites from an Alpine cave (Obir, Austria): seasonal cave physiology
Calcite stalagmites from Obir, an Alpine (1100 m altitude), perennially wet cave, were studied using optical and electron backscatter diffraction petrology, bulk ICP-MS analysis, and microanalysis by ion microprobe and micro-X-ray fluorescence using synchrotron radiation. Drip water penetrates 70 m through Triassic limestones (with some Pb-Zn mineralization) to the chamber Säulenhalle where the...
