•Diatom assemblage from shelf site indicates Pliocene age sediments.
•The site was open marine three times and covered by ice at least four times.

Volume 422, 15 March 2015, Pages 57–64
•We developed a 523-year maximum latewood density chronology for Larix speciosa.
•The maximum density responds well to temperatures in August and September.
•Reconstructing late summer temperature since AD 1690 for the Gaoligong Mountains.
•The reconstruction captures large-scale regional temperature variations.

6. Dynamics of the Australian-Indonesian monsoon across termination II: implications of molecular-biomarker reconstructions from the Timor Sea
Enqing Huang , Jun Tian, Jingjing Liu
•High-resolution vegetation and primary productivity reconstructions over Termination II
•A dramatic expansion of woody plants at the onset of Termination II
•A reduction in monsoon rainfall seasonality during deglacial and interglacial
•SE winter monsoon intensity possibly in phase with boreal winter insolation
Keywords:  Australian-Indonesian monsoon; Vegetation; Sea surface productivity; Timor Sea; Termination II

7. Assessing tree-ring carbon and oxygen stable isotopes for climate reconstruction in the Canadian northeastern boreal forest
Christian Bégin , Mathieu Gingras, Martine M. Savard, Joëlle Marion, Antoine Nicault, Yves Bégin
•We produced tree ring δ18O and δ13C series for a northeastern Canadian boreal site.
•We investigated climate signals in dendroisotopic series.
•We reconstructed summer maximum temperatures for the period of 1800-2004.
•The first half of the 19th century was the coldest period of the past 200 years.
•Trends in the reconstructed series are consistent with other available series.

13. Revisiting tectonic corrections applied to Pleistocene sea-level highstands
Jessica R. Creveling, Jerry X. Mitrovica, Carling C. Hay, Jacqueline Austermann, Robert E. Kopp
•We model the geographic variability in global sea level during the Last Interglacial.
•The calculations include the impact of ice-age cycles and polar ice-sheet collapse.
•A standard method for estimating tectonic uplift rates may introduce large errors.
•This error impacts estimates of peak eustatic sea level during earlier interglacials.
Keywords: Ice age; Sea level; Tectonics; Interglacial; Ice volumes; Geophysical modeling

14. Heterogeneous growth of cadmium and cobalt carbonate phases at the View the MathML source (1014) calcite surface
Man Xu, Eugene S. Ilton, Mark H. Engelhard, Odeta Qafoku, Andrew R. Felmy, Kevin M. Rosso, Sebastien Kerisit

•Cd- and Co-reacted CaCO3 single crystals were imaged in situ with AFM and analyzed ex situ with XPS.
•Cd-reacted crystals showed evidence of the formation of Cd-rich (Ca,Cd)CO3 heteroepitaxial solid solutions.
•A hydroxy-carbonate Co phase that did not grow epitaxially formed on Co-reacted crystals.
•Observed differences are rationalized based on differences in lattice misfits between CdCO3 or CoCO3 and CaCO3.
•The satellite structure of the Co 2p photoelectron line is a reliable tool to identify Co(II) coordination environments.


15. Cleaning and pre-treatment procedures for biogenic and synthetic calcium carbonate powders for determination of elemental and boron isotopic compositions
M. Holcomb, T.M. DeCarlo, V. Schoepf, D. Dissard, K. Tanaka, M. McCulloch
•Cleaning carbonate samples helps to remove seawater contamination.
•We show that for many samples, different cleaning protocols have little influence on the boron isotopic composition.
•Dissolution during cleaning can significantly alter the composition of heterogeneous samples.
