This atlas is the culmination of one of the most comprehensive environmental geochemical studies ever undertaken on a regional scale. It covers some of the most polluted, and some of the most pristine areas in Europe. It provides data for many elements for which the media concerned have not previously been analysed on a large regional scale and demonstrates that many of these are part of the emission spectra from industries within the area covered....

The upper 200 m of the sediments recovered during IODP Leg 302, the Arctic Coring Expedition (ACEX), to the Lomonosov Ridge in the central Arctic Ocean consist almost exclusively of detrital material. The scarcity of biostratigraphic markers severely complicates the establishment of a reliable chronostratigraphic framework for these sediments, which contain the first continuous record of the Neogene environmental and climatic evolution of the Arctic region. Here we present profiles of cosmogenic 10Be together with...

Age and chemical composition of apatites from five DSDP and ODP Sites in the Pacific, Atlantic and Indian Oceans, supplement to: Spiegel, Cornelia; Kohn, Barry; Raza, Asaf; Rainer, Thomas; Gleadow, Andrew (2007): The effect of long-term low-temperature exposure on apatite fission track stability: A natural annealing experiment in the deep ocean. Geochimica et Cosmochimica Acta, 71(18), 4512-4537

Cornelia Spiegel, Barry Kohn, Asaf Raza, Thomas Rainer & Andrew Gleadow
Since studies on deep-sea cores were carried out in the early 1990s it has been known that ambient temperature may have a marked affect on apatite fission track annealing. Due to sluggish annealing kinetics, this effect cannot be quantified by laboratory annealing experiments. The unknown amount of low-temperature annealing remains one of the main uncertainties for extracting thermal histories from fission track data, particularly for samples which experienced slow cooling in shallow crustal levels. To...

Earth and Planetary Science Letters, 265(1-2), 112-122

Aradhna K Tripati, Robert A Eagle, Andrew C Morton, Julian A Dowdeswell, Katie L Atkinson, Yannick Bahé, Caroline F Dawber, Emma Khadun, Ruth M H Shaw, Oliver Shorttle & Lavaniya Thanabalasundaram
The widely accepted age estimate for the onset of glaciation in the Northern Hemisphere ranges between 2 and 15 million years ago (Ma). However, recent studies indicate the date for glacial onset may be significantly older. We report the presence of ice-rafted debris (IRD) in ~44 to 30 Ma sediments from the Greenland Sea, evidence for glaciation in the North Atlantic during the Middle Eocene to Early Oligocene. Detailed sedimentological evidence indicates that glaciers extended...

Physical properties measured on 68 sediment cores from METEOR cruise M29/2

Tilo von Dobeneck, Andre Janke & Andrea Schmidt
