Short summary
Arctic coastal landscapes, like those in northernmost Alaska, often contain saline sediments that are more prone to thawing. We studied six sediment cores to understand how thawing and salinity affect organic carbon breakdown and land change. Our results show that salinity speeds up organic matter loss when permafrost thaws. This highlights the overlooked risk of salinity in shaping Arctic landscapes and carbon release as the climate continues to warm.

With regard to global warming, an understanding of past temperature changes is becoming increasingly important. Branched glycerol dialkyl glycerol tetraethers (brGDGTs) are membrane lipids used globally to reconstruct lake water temperatures. In the Bale Mountains lakes, we find a unique composition of brGDGT isomers. We present a modified local calibration and a new high-altitude temperature reconstruction from the Horn of Africa spanning the last 12.5 kyr.

Charcoals and leaf waxes from vegetation accumulate in the soil and provide information about past vegetation because they are mostly resistant against physical and biological degradation. Analyzing and comparing ratios of both element types helped us to improve the evidence for vegetation reconstruction. We found that the accumulation processes and preservation of these elements depend on different environmental conditions at forest- and steppe-dominated sites in the Mongolian forest–steppe.

Faecal biomarker analyses present a useful tool in geoarcheological research. For a better understanding of the lives of our ancestors in alpine regions, we investigated modern livestock faeces and Holocene soils at the prehistorical encampment site of Ullafelsen in the Fotsch Valley, Stubai Alps, Austria. Initial results show a high input of livestock faeces and a negligible input of human faeces for this archeological site. Future studies will focus on mire archives in the Fotsch Valley.

Radiocarbon (14C) is an optimal tracer of methane (CH4) emissions, as 14C measurements enable distinguishing between fossil methane and biogenic methane. However, these measurements are particularly challenging, mainly due to technical difficulties in the sampling procedure. We made the sample extraction much simpler and time efficient, providing a new technology that can be used by any research group, with the goal of expanding 14C measurements for an improved understanding of methane sources.

Reports on molecular-level knowledge of high-temporal-resolution particulate matter ≤2.5 µm in diameter (PM2.5) on hazy days are limited. We investigated various PM2.5 species and their sources. The results show biomass burning (BB) was the main source of organic carbon. Moreover, BB enhanced fungal spore emissions and secondary aerosol formation. The contribution of non-fossil sources increased with increasing haze pollution, suggesting BB may be an important driver of haze events in winter.

We explored CO2 from soil to subsurface at Milandre cave, finding very high concentrations at all depths. While forest soils produced modern CO2 year-round, cave and meadow soil CO2 influences varies with temperature controlled cave ventilation, with older CO2 input in winter from old organic matter stored underground. These findings show that CO2 fluxes in karst systems are highly dynamic, and a better understanding of them is important for accurate carbon cycle modelling.

We reconstruct environmental changes derived from sediments of Schweriner See, a large lake in NE Germany, for the past 3000 years. We infer variations in North Atlantic large-scale atmospheric circulation systems, namely the North Atlantic Oscillation (NAO), by combining sedimentological, geochemical, and biological parameters. Our results suggest distinct shifts between positive and negative NAO phases affecting winter temperatures, precipitation, and westerly wind strength at our study site.

The lake drilling project at Lake Hallstatt (Austria) successfully cored 51 m of lake sediments. This was achieved through the novel drilling platform Hipercorig. A core-log seismic correlation was created for the first time of an inner Alpine lake of the Eastern Alps. The sediments cover over 12 000 years before present with 10 (up to 5.1 m thick) instantaneous deposits. Lake Hallstatt is located within an UNESCO World Heritage area which has a rich history of human salt mining.

We discuss carbonaceous aerosol (CA) observed at the high Arctic Zeppelin Observatory (2017 to 2020). We find that organic aerosol is a significant fraction of the Arctic aerosol, though less than sea salt aerosol and mineral dust, as well as non-sea-salt sulfate, originating mainly from anthropogenic sources in winter and from natural sources in summer, emphasizing the importance of wildfires for biogenic secondary organic aerosol and primary biological aerosol particles observed in the Arctic.

This study presents a palaeoenvironmental record from Lake Höglwörth, Bavaria, Germany. Before 870 CE peat deposits existed. Erosion increased from 1240 to 1380 CE, followed by aquatic productivity and anoxia from 1310 to 1470 CE. Increased allochthonous input and a substantial shift in the aquatic community in 1701 were caused by construction of a mill. Recent anoxia has been observed since the 1960s.

Primary succession in proglacial areas depends on complex driving forces. To concretise the complex effects and interaction processes, 39 known explanatory variables assigned to seven spheres were analysed via principal component analysis and generalised additive models. Key results show that in addition to time- and elevation-dependent factors, also disturbances alter vegetation development. The results are useful for debates on vegetation development in a warming climate.

Carbon-containing aerosols from ambient air are analysed for radioactive isotope radiocarbon to determine the contribution from fossil-fuel emissions. Light-absorbing soot-like aerosols are isolated by water extraction and thermal separation. This separation is affected by artefacts, for which we developed a new correction method. The investigation of aerosols from the Arctic shows that our approach works well for such samples, where many artefacts are expected.

Deriving more quantitative climate information like relative air humidity is one of the key challenges in paleostudies. Often only qualitative reconstructions can be done when single-biomarker-isotope data are derived from a climate archive. However, the coupling of hemicellulose-derived sugar with leaf-wax-derived n-alkane isotope results has the potential to overcome this limitation and allow a quantitative relative air humidity reconstruction.

This study provides a holistic approach to studying the spectrally resolved light absorption by atmospheric brown carbon (BrC) and black carbon using long time series of daily samples from filter-based measurements. The obtained results provide (1) a better understanding of the aerosol absorption profile and its dependence on BrC and on lensing from less absorbing coatings and (2) an estimation of the most important absorbers at typical European locations.

This study presents a multi-proxy record from Lake Voёlvlei and provides new insights into the sea level and paleoclimate history of the past 8.5 ka at South Africa’s southern Cape coast. Our results show that sea level changes at the southern coast are in good agreement with the western coast of South Africa. In terms of climate our record provides valuable insights into changing sources of precipitation at the southern Cape coast, i.e. westerly- and easterly-derived precipitation contribution.

This study provides a newly developed method which combines radiocarbon (14C) with organic tracers to enable source apportionment of primary and secondary fossil vs. non-fossil sources of carbonaceous aerosols at an urban and a rural site of Beijing. The source apportionment results were compared with those by chemical mass balance and AMS/ACSM-PMF methods. Correlations of WINSOC and WSOC with different sources of OC were also performed to elucidate the formation mechanisms of SOC.

We studied snails from Holocene river sediments of the upper Alazani River in the southeastern Caucasus. Since no natural floodplain forests existed in the river valley until ca. 4500 years ago, our snail data confirm a formerly suggested regional settlement center from the ca. 8000 years unknown thus far. Furthermore, increasing proportions of water-related snails for ca. 4000 years indicate a shift of the river course possibly linked with the formation of the Greater Caucasus.
