“…The application of stable isotope analysis in combination with the classical dendrochronology is steadily increasing because stable isotope ratios, particularly 13 C/ 12 C and 18 O/ 16 O in wood or cellulose provide complementary information about climatic variabilities (McCarroll and Loader 2004;Saurer et al 2002;Skomarkova et al 2006;Gagen et al 2006;Kirdyanov et al 2008;Kress 2009;Sidorova et al 2008Sidorova et al , 2010. The 13 C/ 12 C isotopic ratio in tree-rings reflects water availability and air humidity both impacting carbon and water relations.…”

For the first time we present a multi-proxy data set for the Russian Altai, consisting of Siberian larch treering width (TRW), latewood density (MXD), d13 C and d18 O in cellulose chronologies obtained for the period 1779-2007 and cell wall thickness (CWT) for 1900-2008. All of these parameters agree well between each other in the high-frequency variability, while the low-frequency climate information shows systematic differences. The correlation analysis with temperature and precipitation data from the closest weather station and gridded data revealed that annual TRW, MXD, CWT, and d 13 C data contain a strong summer temperature signal, while d18 O in cellulose represents a mixed summer and winter temperature and precipitation signal. The temperature and precipitation reconstructions from the Belukha ice core and Teletskoe lake sediments were used to investigate the correspondence of different independent proxies. Low frequency patterns in TRW and d 13 C chronologies are consistent with temperature reconstructions from nearby Belukha ice core and Teletskoe lake sediments showing a pronounced warming trend in the last century. Their combination could be used for the regional temperature reconstruction. The long-term d18 O trend agrees with the precipitation reconstruction from the Teletskoe lake sediment indicating more humid conditions during the twentieth century. Therefore, these two proxies could be combined for the precipitation reconstruction.

“…Waterhouse et al, 2000;Holzkämper et al, 2008;2012;Sidorova et al, 2008;Porter et al, 2009). The combination of long-lived trees, robust dendrochronologies and excellent sample preservation both on land and in lakes have facilitated the development of several multi-centennial to millennial length isotopic records (Boettger et al, 2003;Kremenetski et al, 2004;Sidorova et al, 2008;Young et al, 2010;Gagen et al, 2011;Loader et al, 2013;Porter et al, 2014). However, because moisture is rarely the dominant tree-growth limiting factor across much of the Arctic region, there 10 is a limitation of the hydroclimate information that can be reconstructed using the isotopic approach.…”

Abstract. Along with Arctic amplification, changes in Arctic hydroclimate have become increasingly apparent. Reanalysis data show increasing trends in Arctic temperature and precipitation over the 20 th century, but changes are not homogenous 30 across seasons or space. The observed hydroclimate changes are expected to continue, and possibly accelerate, in the coming century, not only affecting pan-Arctic natural ecosystems and human activities, but also lower latitudes through changes in atmospheric and oceanic circulation. However, a lack of spatiotemporal observational data makes reliable quantification of Arctic hydroclimate change difficult, especially in a long-term context. To understand hydroclimate variability and the mechanisms driving observed changes, beyond the instrumental record, climate proxies are needed. Here we bring together 35 the current understanding of Arctic hydroclimate during the past 2000 years, as inferred from natural archives and proxies and palaeoclimate model simulations. Inadequate proxy data coverage is apparent, with distinct data gaps in most of Eurasia and parts of North America, which makes robust assessments for the whole Arctic currently impossible. Hydroclimate proxies and climate models indicate that the Medieval Climate Anomaly (MCA) was anomalously wet, while conditions Clim.

However, it is clear that there are large regional differences, which are especially evident during the LIA. Due to the spatiotemporal differences in Arctic hydroclimate, we recommend detailed regional studies, e.g. including field reconstructions, to disentangle spatial patterns and potential forcing factors. At present, it is only possible to carry out regional syntheses for a few areas of the Arctic, e.g. Fennoscandia, Greenland and western North America. To fully assess pan-Arctic hydroclimate variability for the last two 5 millennia additional proxy records are required.

“…Additionally, the sedimentary δD wax also represents an integrated signal of precipitation for the last 200 yr. Longterm δD p records are lacking at this site. However, the reconstructed estimates of δD p from the northern Yakutia δ 18 O cellulose record (Sidorova et al, 2008) yields a 97-yraverage reconstructed δD p of approximately −147 ‰. Net fractionations between core top sediments and either streams (ε C30/streams = −103 ± 5 ‰) or precipitation (ε C30/precip = −95 ± 5 ‰) closely agree with ε wax/w values from modern vegetation (streams: ε wax/streams = −116 ± 12 ‰; precipitation: ε wax/precip = −107 ± 12 ‰).…”

“…Initial lake conditions were assigned based on the present-day mean δD lake (−155 ‰) and are similar to reconstructed input approximations. As long-term records of past δD p are lacking in this region, we used δ 18 O data from tree ring cellulose in northern Siberia (Sidorova et al, 2008) to reconstruct the isotopic ratios of past precipitation for input to our model. In order to derive isotope ratios of precipitation from δ 18 O cellulose , we used the relationship between source water (here assumed to be precipitation) and δ 18 O cellulose described in Anderson et al (2002).…”

Modern isotope hydrology and controls on δD of plant leaf waxes at Lake El'gygytgyn, NE Russia

Abstract. Stable isotope data from lipid biomarkers and diatom silica recovered from lake sediment cores hold great promise for paleoclimate and paleohydrological reconstructions. However, these records rely on accurate calibration with modern precipitation and hydrologic processes and only limited data exist on the controls on the δD values for n-alkanoic acids from plant leaf waxes. Here we investigate the stable isotopic composition of modern precipitation, streams, lake water and ice cover, and use these data to constrain isotope systematics of the Lake El'gygytgyn Basin hydrology. Compound-specific hydrogen isotope ratios determined from n-alkanoic acids from modern vegetation are compared with modern precipitation and lake core top sediments. Multi-species net (apparent) fractionation values between source water (precipitation) and modern vegetation (e.g., &varepsilon;wax/precip mean value is −107 ± 12‰) agree with previous results and suggest a consistent offset between source waters and the δD values of alkanoic acids. We conclude that although there may be some bias towards a winter precipitation signal, overall δD values from leaf wax n-alkanoic acids record annual average precipitation within the El'gygytgyn Basin. A net fractionation calculated for 200-yr-integrated lake sediments yields &varepsilon;30/precip = −96 ± 8‰ and can provide robust net "apparent" fractionation to be used in future paleohydrological reconstructions.
