“…The lake littoral zone was vegetated by macrophytes and the regional vegetation was southern shrub tundra. The deduced warmest conditions during the early Holocene between about 10.5 and 8 cal kyr BP in the Kolyma Lowland probably correspond to earlier findings along a north‐to‐south transect at the Lena River, where lake sediments were used to reconstruct summer climate . Biskaborn et al showed warmest conditions during the early Holocene in the northernmost locations of the transect, in the Lena Delta.…”

Ground ice and sedimentary records of a pingo exposure reveal insights into Holocene permafrost, landscape and climate dynamics. Early to mid‐Holocene thermokarst lake deposits contain rich floral and faunal paleoassemblages, which indicate lake shrinkage and decreasing summer temperatures (chironomid‐based TJuly) from 10.5 to 3.5 cal kyr BP with the warmest period between 10.5 and 8 cal kyr BP. Talik refreezing and pingo growth started about 3.5 cal kyr BP after disappearance of the lake. The isotopic composition of the pingo ice (δ18O − 17.1 ± 0.6‰, δD −144.5 ± 3.4‰, slope 5.85, deuterium excess −7.7± 1.5‰) point to the initial stage of closed‐system freezing captured in the record. A differing isotopic composition within the massive ice body was found (δ18O − 21.3 ± 1.4‰, δD −165 ± 11.5‰, slope 8.13, deuterium excess 4.9± 3.2‰), probably related to the infill of dilation cracks by surface water with quasi‐meteoric signature. Currently inactive syngenetic ice wedges formed in the thermokarst basin after lake drainage. The pingo preserves traces of permafrost response to climate variations in terms of ground‐ice degradation (thermokarst) during the early and mid‐Holocene, and aggradation (wedge‐ice and pingo‐ice growth) during the late Holocene.

“…Overall, attempts to reconstruct winter temperatures from biological proxies (such as pollen and beetles) have had little success. Recently, however, a study by Biskaborn et al revealed the potential of using diatoms ( Fragilaria spp.) of the spring bloom as a winter–spring climate proxy, which also confirmed the ice‐wedge‐based Holocene winter warming trend …”

Ice wedges are a characteristic feature of northern permafrost landscapes and grow mainly by snowmelt that refreezes in thermal contraction cracks that open in winter. In high latitudes the stable‐isotope composition of precipitation (δ18O and δD) is sensitive to air temperature. Hence, the integrated climate information of winter precipitation is transferred to individual ice veins and can be preserved over millennia, allowing ice wedges to be used to reconstruct past winter climate. Recent studies indicate a promising potential of ice‐wedge‐based paleoclimate reconstructions for more comprehensive reconstructions of Arctic past climate evolution. We briefly highlight the potential and review the current state of ice‐wedge paleoclimatology. Existing knowledge gaps and challenges are outlined and priorities for future ice‐wedge research are suggested. The major research topics are (1) frost cracking and infilling dynamics, (2) formation and preservation of the stable‐isotope information, (3) ice‐wedge dating, (4) age‐model development and (5) interpretation of stable‐isotope time series. Progress in each of these topics will help to exploit the paleoclimatic potential of ice wedges, particularly in view of their unique cold‐season information, which is not adequately covered by other terrestrial climate archives.

“…Based on multiple parameters, mainly aquatic (diatoms) and terrestrial (pollen) bio-indicators and sediment geochemical proxies from radiocarbon dated sediment cores, several studies (synthesized in Biskaborn et al 2016) revealed the timing and magnitude of the onset of the HTM. These authors documented a temporal delay from north to south along Fig.…”

“…Such a southward delay in HTM onset appeared to be up to 3000 years, although the termination of the HTM is still under debate. Based on bio-and lithostratigraphic reconstructions, Biskaborn et al (2012Biskaborn et al ( , 2013aBiskaborn et al ( , 2016 reported that climate warming in the Lena Delta hinterland caused major changes in aquatic ecosystems (e.g., decrease in lake-ice cover extent and duration, decrease in alkalinity, increase in habitat availability). Furthermore, these studies demonstrated that use of bio-indicators for climate reconstruction requires differentiation between summer and winter seasons.…”

Paleolimnology of thermokarst lakes: a window into permafrost landscape evolution

Widespread across northern permafrost landscapes, thermokarst ponds and lakes provide vital wildlife habitat and play a key role in biogeochemical processes. Stored in the sediments of these typically shallow and dynamic waterbodies are rich sources of paleoenvironmental information whose potential has not yet been fully exploited, likely because of concerns over stratigraphic preservation and challenges to develop reliable sediment core chronologies. Here, we present an overview of recently derived informative paleolimnological reconstructions based on multiparameter analysis of sediment archives from permafrost aquatic basins. We include examples from across the Canadian North, Alaska, and Siberia that illustrate their value for providing insights into temporal patterns of lake inception, catchment erosion, aquatic productivity, hydrological evolution, and landscape disturbances. Although not captured in our survey, emerging research directions focused on carbon accumulation, storage, and balance hold much promise for contributing to global climate change science.Key words: thermokarst lakes, permafrost, paleolimnology, lake sediments.Résumé : Répandus d'un paysage de pergélisol septentrional à l'autre, les étangs et les lacs thermokarstiques fournissent un habitat essentiel à la faune et jouent un rôle clé dans les processus biogéochimiques. Accumulées dans les sédiments de ces plans d'eau typiquement peu profonds et dynamiques se trouvent des sources riches en informations paléoenvironne-mentales dont le potentiel n'a pas encore été entièrement exploité, probablement à cause des préoccupations concernant la conservation stratigraphique et les défis de développer des chronologies fiables à partir des carottes sédimentaires. Ici, nous présentons une vue d'ensemble des reconstitutions paléolimnologiques informatives récemment dérivées d'après l'analyse multi paramétrée d'archives de sédiments des bassins aquatiques du pergé-lisol.

Bien que non mises en lumière dans notre enquête, les directions de recherche émergentes centrées sur l'accumulation, le stockage et le bilan carbone s'annoncent bien quant à leur contribution à la science du changement climatique mondial.
