1. Compound-specific carbon and nitrogen isotopic compositions of chlorophyll a and its derivatives reveal the eutrophication history of Lake Zurich (Switzerland)
Sebastian Naeher , Hisami Suga, Nanako O. Ogawa, Carsten J. Schubert, Kliti Grice, Naohiko Ohkouchi
•Pigment distributions reflect rapid pheopigment formation in water column and sediments.
•δ13C and δ15N values of chlorins follow historical trends of eutrophication and reoligotrophication.
•Historical trends in δ15N values of chlorins mainly related to population changes of Planktothrix rubescens.
•δ15N offsets of pigments in surface sediment explained by higher contributions of laterally transported OM

2. Behavior of U, Th and Ra isotopes in soils during a land cover change

Quaternary Science Reviews
3. Natural and anthropogenic drivers of cultural change on Easter Island: Review and new insights
Valentí Rull
•Easter Island's cultural change is analyzed from a holistic perspective.
•Two, possibly three, social shifts occurred during the las millennium.
•Drought, deforestation and external cultural influence played a role.

4. Holocene paleoclimate inferred from salinity histories of adjacent lakes in southwestern Sicily (Italy)
Brandon Currya, , , Paul D. Henneb, c, Francesc Mezquita-Joanesd, Federico Marronee, Valentina Pierif, Tommaso La Mantiag, Camilla Calòc, Willy Tinner

•Holocene paleosalinity reconstructions from two adjacent lakes in coastal Sicily have different trends and values.
•An abrupt rise in paleosalinity at 6250 cal yr BP at Lago Preola is attributed to the intrusion and diffusion of sea water.
•Paleosalinity of Gorgo Basso was highest during the early Holocene, and lowest during the last 2000 years.
•Gorgo Basso’s decline in salinity during the late Holocene reflects increased effective moisture.
•Isotopic data indicate relatively more early Holocene winter precipitation than during the late Holocene.

5. Long-term record of Barents Sea Ice Sheet advance to the shelf edge from a 140,000 year record
Ed L. Popea, , , Peter J. Tallinga, b, James E. Hunta, Julian A. Dowdeswellc, Joshua R. Allina, Matthieu J.B. Cartignya, David Longd, Alessandro Mozzatoa, Jennifer D. Stanforde, David R. Tappind, Millie Watts
•New Barents Sea Ice Sheet history for last 140,000 years is reconstructed.
•Glacigenic-debris flows are used to reconstruct ice-sheet history.
•Four advances to the shelf edge of the Bjørnøyrenna Trough are reconstructed.
•Weichselian and Saalian Barents Sea Ice Sheets had different configurations.
•Saalian ice-sheet was stable at the shelf edge longer than any Weichselian ice-sheet.

6. Identification of the Changbaishan ‘Millennium’ (B-Tm) eruption deposit in the Lake Suigetsu (SG06) sedimentary archive, Japan: Synchronisation of hemispheric-wide palaeoclimate archives
Danielle McLeana, , , Paul G. Alberta, Takeshi Nakagawab, c, Richard A. Staffa, Takehiko Suzukid, Suigetsu 2006 Project Members1, Victoria C. Smith
•East Asian palaeoclimate record synchronised to the Greenland ice cores using tephra.
•Suggests more ash layers that are common to both archives will be discovered.
•Lake Suigetsu records, to date, the most southerly occurrence of the B-Tm tephra.
•Identification of the B-Tm helps constrain the Holocene chronology of the SG06 core.

7. Regolith evolution on the millennial timescale from combined U–Th–Ra isotopes and in situ cosmogenic 10Be analysis in a weathering profile (Strengbach catchment, France)
J. Ackerer, F. Chabaux, J. Van der Woerd, D. Viville, E. Pelt, E. Kali, C. Lerouge, P. Ackerer, R. di Chiara Roupert, P. Négrel
•Analysis of U-series isotopes and in situ 10Be in a single regolith profile.
•Independent determination of long term regolith denudation and production rates.
•Lower regolith is the most suitable place to quantify regolith production rate.
•A high spatial resolution profile is required for an extensive modeling of in situ 10Be.
•Higher temporal variability of physical erosion than chemical weathering.

8. The cosmogenic record of mountain erosion transmitted across a foreland basin: Source-to-sink analysis of in situ10Be, 26Al and 21Ne in sediment of the Po river catchment
Hella Wittmann, Marco G. Malusà, Alberto Resentini, Eduardo Garzanti, Samuel Niedermann

9. Synchronicity of Kuroshio Current and climate system variability since the Last Glacial Maximum
Xufeng Zheng, Anchun Li, ShuhJi Kao, Xun Gong, Martin Frank, Gerhard Kuhn, Wenju Cai, Hong Yang, Shiming Wan, Honghai Zhang, Fuqing Jiang, Edmund Hathorne, Zhong Chen, Bangqi Hu
•Kuroshio Current proxy was established by statistical analyses on grain size spectrum.
•Sr–Nd isotope analyses on Kuroshio grain size spectrum reveals source of Taiwan.
•Synchronous shift in ENSO and the North Pacific Gyre is subject to the insolation.
•Earth System Modeling results confirm our proxies-indicated Kuroshio Current strength.

10. When and why sediments fail to record the geomagnetic field during polarity reversals
Jean-Pierre Valeta, , , Laure Meynadiera, Quentin Simonb, Nicolas Thouveny
•Reversal records from sediments with v<5 cm="" did="" directions.="" kyr="" not="" o:p="" provide="" suitable="">
•No characteristic component is isolated from weakly and highly magnetized sediments as well.
•Rapid field changes are integrated within a 2 cm sample and yield multiple magnetic components.
•When present post-depositional processes smear out the signal and provide unsuitable records.
•Current paleomagnetic techniques are not appropriate for reversal studies from sediments.
