DOI: 10.1016/j.quascirev.2014.05.008

2. Optimising the use of marine tephrochronology in the North Atlantic: a detailed investigation of the Faroe Marine Ash Zones II, III and IV

Adam J. Griggs , Siwan M. Davies , Peter M. Abbott , Tine L. Rasmussen , Adrian P. Palmer

DOI: 10.1016/j.quascirev.2014.04.031

Highlights

•MIS 2-3 tephrostratigraphy for a North Atlantic marine core.

•Geochemical and sedimentological analysis is used to assess tephra taphonomy.

•FMAZ II and IV can be used as isochrons for high-precision correlation studies.

•FMAZ III cannot presently be used as a marine-ice isochron in high-precision studies.

•We provide a protocol for assessing secondary deposition in the North Atlantic.

3. The marine-based NW Fennoscandian ice sheet: glacial and deglacial dynamics as reconstructed from submarine landforms

Tom Arne Rydningen , Tore O. Vorren , Jan Sverre Laberg , Vidar Kolstad

DOI: 10.1016/j.quascirev.2013.02.013

Highlights

► High resolution data revealed excellent details of submarine glacial landforms. ► Estimated palaeo-ice stream velocities during LGM were about 350 m/year. ► A rapid early deglaciation in the troughs was followed by a stepwise recession. ► The deglaciation of the banks was characterized by minor halts and readvances. ► The trough widths probably exerted an important control on the deglacial dynamics.

4. Palaeo-seasonality of the last two millennia reconstructed from the oxygen isotope composition of carbonates and diatom silica from Nar Gölü, central Turkey

Jonathan R. Dean , Matthew D. Jones , Melanie J. Leng , Hilary J. Sloane , C. Neil Roberts , Jessie Woodbridge , George E.A. Swann , Sarah E. Metcalfe , Warren J. Eastwood , Hakan Yiğitbaşıoğlu

DOI: 10.1016/j.quascirev.2012.07.014

Highlights

► Comparing δ¹⁸O from carbonates and diatoms allows insights into seasonality. ► Use of data from lake monitoring to help interpret down-core isotope variations. ► Severe winters inferred 301–801 AD, 921–1071 AD and 1821–1898 AD.

5. Hydrological instability during the Last Interglacial in central Asia: a new diatom oxygen isotope record from Lake Baikal

Anson W. Mackay , George E.A. Swann , Nathalie Fagel , Susanne Fietz , Melanie J. Leng , David Morley , Patrick Rioual , Pavel Tarasov

DOI: 10.1016/j.quascirev.2012.09.025

Highlights

► A new Last Interglacial, isotopic record of diatom silica (δ¹⁸O_diatom) from Lake Baikal was investigated. ► Fluctuations in the isotopic record suggest strong teleconnections with Atlantic meridional overturning circulation. ► Millennial scale variability during Last Interglacial was significantly less pronounced than during the Holocene.

6. Carbon cycling within an East African lake revealed by the carbon isotope composition of diatom silica: a 25-ka record from Lake Challa, Mt. Kilimanjaro

Philip A. Barker , Elizabeth R. Hurrell , Melanie J. Leng , Birgit Plessen , Christian Wolff , Daniel J. Conley , Eddy Keppens , Isla Milne , Brian F. Cumming , Kathleen R. Laird , Chris P. Kendrick , Peter M. Wynn , Dirk Verschuren

DOI: 10.1016/j.quascirev.2012.07.016

7. Morphological analysis and evolution of buried tunnel valleys in northeast Alberta, Canada

N. Atkinson , L.D. Andriashek , S.R. Slattery

DOI: 10.1016/j.quascirev.2012.11.031

Highlights

► Subsurface geologic data documents the distribution of tunnel valleys in NE Alberta. ► Tunnel valleys fills comprise multistory, erosion- to succession-dominated deposits. ► Deposits reflect allogenic and autogenic controls due to a sequence of jökulhlaups. ► Tunnel valley systems evolved time transgressively. ► Evolution is in part related to substrate lithology and subglacial hydraulics.

8. High resolution Lateglacial and early-Holocene summer air temperature records from Scotland inferred from chironomid assemblages

Stephen J. Brooks , Ian P. Matthews , Hilary H. Birks , H.John B. Birks

DOI: 10.1016/j.quascirev.2012.03.007

Highlights

► Lateglacial chironomid-inferred summer air temperatures for two Scottish sites. ► Lateglacial temperature trends are broadly consistent between both sites and NGRIP. ► Local and regional forcing causes between-site differences in climate trends. ► If radiocarbon dating is impossible chronology can be developed based on tephra alone.

9. Holocene temperature variations at a high-altitude site in the Eastern Alps: a chironomid record from Schwarzsee ob Sölden, Austria
