Radiocarbon dates, accumulation rates, δ¹³C and July temperature of profiles obtained from Selwyn and Misaw Lake, subarctic Canada, supplement to: Kaislahti Tillman, Päivi; Holzkämper, Steffen; Kuhry, Peter; Sannel, A Britta K; Loader, Neil J; Robertson, Iain (2010): Long-term climate variability in continental subarctic Canada: A 6200-year record derived from stable isotopes in peat. Palaeogeography, Palaeoclimatology, Palaeoecology, 298(3-4), 235-246

The rapid warming of arctic regions during recent decades has been recorded by instrumental monitoring, but the natural climate variability in the past is still sparsely reconstructed across many areas. We have reconstructed past climate changes in subarctic west-central Canada. Stable carbon and oxygen isotope ratios (d13C, d18O) were derived from a single Sphagnum fuscum plant component; alpha-cellulose isolated from stems. Periods of warmer and cooler conditions identified in this region, described in terms of...

Establishment, expansion and regeneration of aspen (Populus tremula) in the Torneträsk area, subarctic Sweden, supplement to: Van Bogaert, Rik; Jonasson, Christer; De Dapper, Morgan; Callaghan, Terry V (2010): Range expansion of thermophilic aspen (Populus tremula L.) in the swedish Subarctic. Arctic, Antarctic, and Alpine Research, 42(3), 362-375

Rik Van Bogaert, Christer Jonasson, Morgan De Dapper & Terry V Callaghan
In subarctic Sweden, recent decadal colonization and expansion of aspen (Populus tremula L.) were recorded. Over the past 100 years, aspen became c. 16 times more abundant, mainly as a result of increased sexual regeneration. Moreover, aspen now reach tree-size (>2 m) at the alpine treeline, an ecotone that has been dominated by mountain birch (Betula pubescens ssp. czerepanovii) for at least the past 4000 years. We found that sexual regeneration in aspen probably occurred...

Paleoceanography, 16(2), 155-163

In the latest Paleocene an abrupt shift to more negative d13C values has been documented at numerous marine and terrestrial sites (Bralower et al., 1997, doi:10.1130/0091-7613(1997)025<0963:HRROTL>2.3.CO;2; Cramer et al., 1999; Kaiho et al., 1996, doi:10.1029/96PA01021; Kennett and Stott, 1991, doi:10.1038/353225a0; Koch et al., 1992, doi:10.1038/358319a0; Stott et al., 1996; Thomas and Shackleton, 1996, doi:10.1144/GSL.SP.1996.101.01.20; Zachos et al., 1993). This carbon isotope event (CIE) is coincident with oxygen isotope data that indicate warming of surface waters...

Age determination and sedimentology of sediment core Lz1101 from the Melles Lake, supplement to: Klug, Martin; Bennike, Ole; Wagner, B (2009): Repeated short-term bioproductivity changes in a coastal lake on Store Koldewey, northeast Greenland: an indicator of varying sea-ice coverage? The Holocene, 19(4), 653-663

Martin Klug, Ole Bennike & Bernd Wagner
A lacustrine sediment core from Store Koldewey, northeast Greenland, was biogeochemically, biologically and sedimentologically investigated in order to reconstruct long- and short-term climatic and environmental variability. The chronology of the uppermost 189 cm of the record is based on ten 14C AMS age determinations of aquatic mosses. The record covers almost the entire Holocene and revealed changes on multidecadal to centennial scales. Dating of the oldest mosses shows that lacustrine biogenic productivity already began at...

Radiocarbon age, and sedimentation and accumulation rate of core JM05-G001 obtained during Jan Mayen cruise JM050704 to the Barents Sea, supplement to: Wilson, Laurie J; Hald, Morten; Godtliebsen, Fred (2011): Foraminiferal faunal evidence of twentieth-century Barents Sea warming. The Holocene, 21(4), 527-537

Laurie J Wilson, Morten Hald & Fred Godtliebsen
Instrumental monitoring of the climate at high northern latitudes has documented the ongoing warming of the last few decades. Climate modelling has also demonstrated that the global warming signal will be amplified in the polar region. Such temperature increases would have important implications on the ecosystem and biota of the Barents Sea. This study therefore aims to reconstruct the climatic changes of the Barents Sea based on benthic foraminifera over approximately the last 1400 years...

Upper air soundings during POLARSTERN cruise PS90 (ANT-XXX/3)

Gert König-Langlo
The upper air soundings are normally performed once a day to measure vertical profiles of air pressure, temperature, relative humidity and the wind vector. Helium filled balloons (TOTEX 600 g, 800 g) were used to carry Vaisala RS92-SGPW radiosondes. Whenever possible, the launches were performed about 10 UTC. Condensed measurements (TEMP Format FM-35) were transferred without delay into the Global Telecommunication System GTS were they contribute for the world wide weather forecasts. The profile data...

Within the scope of Russian-German palaeoenvironmental research, Two-Yurts Lake (TYL, Dvuh-Yurtochnoe in Russian) was chosen as the main scientific target area to decipher Holocene climate variability on Kamchatka. The 5x2 km large and 26 m deep lake is of proglacial origin and situated on the eastern flank of Sredinny Ridge at the northwestern end of the Central Kamchatka Valley, outside the direct influence of active volcanism. Here, we present results of a multi-proxy study on...

High-resolution IP25 of three sediment cores in the western North Pacific and Bering Sea, supplement to: Méheust, Marie; Stein, Ruediger; Fahl, Kirsten; Max, Lars; Riethdorf, Jan-Rainer (2015): High-resolution IP25-based reconstruction of sea-ice variability in the western North Pacific and Bering Sea during the past 18,000 years. Geo-Marine Letters

Marie Méheust, Ruediger Stein, Kirsten Fahl, Lars Max & Jan-Rainer Riethdorf
Due to its strong influence on heat and moisture exchange between the ocean and the atmosphere, sea ice is an essential component of the global climate system. In the context of its alarming decrease in terms of concentration, thickness and duration, understanding the processes controlling sea-ice variability and reconstructing paleo-sea-ice extent in polar regions have become of great interest for the scientific community. In this study, for the first time, IP25, a recently developed biomarker...

Geochemistry of manganese nodules from the N.W. Indian Ocean, supplement to: Cronan, David S; Tooms, J S (1967): Geochemistry of manganese nodules from the N.W. Indian Ocean. Deep Sea Research and Oceanographic Abstracts, 14(2), 239-249

David S Cronan & J S Tooms
Manganese nodules collected from four sites in the N.W. Indian Ocean by R.R.S. Discovery have been analysed for a range of elements. At two of the sites, samples were collected from two morphological populations, at one of these sites each population being a distinct chemical population also. In addition, considerable differences have been observed in the composition of morphologically similar modules from sites a few miles apart. The information obtained is of significance in any...
