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.

Chemotaxonomic identification of keystone plant species in the Bale Mountains are possible using lignin phenols. However, Erica could not be differentiated chemotaxonomically from all other investigated plants using n-alkanes. Unambiguous characteristic patterns of lignin phenols reflected in the plant samples were not sustained in the organic layers and mineral topsoils. This is due to degradation and organic matter inputs by roots. Therefore, the past extent of Erica is still speculative.

The study evaluates the ability of stable isotopes (δ13C and δ15N) and sugar biomarkers to distinguish Erica from the dominant vegetation of the Bale Mountains in order to reconstruct the past extent of Erica on the Sanetti Plateau. No significant differences in stable isotopes are found between the dominant plant species. Although Erica is characterized by quite high (G+M)/(A+X) ratios, it cannot be unambiguously distinguished from other plants due to degradation and soil microbial effects.

For this study we systematically investigated the molecular pattern of leaf waxes in litter and topsoils along a European transect to assess their potential for palaeoenvironmental reconstruction. Our results show that leaf wax patterns depend on the type of vegetation. The vegetation signal is not only found in the litter; it can also be preserved to some degree in the topsoil.

Stable water isotopes (18O/16O and 2H/1H) are invaluable proxies for paleoclimate research. Here we use a coupled 18O/16O and 2H/1H biomarker approach based on plant-derived sugars and n-alkanes. Applying this innovative approach to a topsoil transect allows for (i) calculating the deuterium-excess of leaf water as a proxy for relative humidity and (ii) calculating the plant source water isotopic composition (~precipitation). The approach is validated by the presented climate transect results.

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.

Radiocarbon (14C) is an optimal tracer of methane (CH4) emissions, as 14C measurements enable distinguishing fossil from biogenic methane. However, these measurements are particularly challenging, mainly due to technical difficulties in the sampling procedure. With this work 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 the molecular level knowledge of high temporal resolution PM2.5 components on hazy days are still limited. This study investigated many individual PM2.5 species and 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-fossils increased with increasing haze pollution. These findings suggest BB may be an important driver of haze events in winter.

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.

We present a novel post Last Glacial Maximum sediment record from Moossee (Swiss Plateau, southern central Europe). For the first time, five major reorganizations of vegetation could be definitely linked to paramount postglacial temperature and/or moisture changes. Present-day beech-dominated forests have been resilient to long-term climate change and human land use. They may prevail in future if climate warming does not exceed the amplitude of Mid Holocene temperature and moisture variability.

In a small, deep lake on the Swiss Plateau, net fluxes of labile P fractions in sediments that can be released to surface waters have been predominately controlled by past hypolimnetic anoxic conditions since the early 1900s. More than 40 years of hypolimnetic withdrawal can effectively reduce net P fluxes in sediments and internal P loads but not effectively decrease eutrophication. These findings should likely serve the management of deep eutrophic lakes in temperate zones.

This study investigates the age and origin of leaf wax n-alkanes from a fluvial sediment–paleosol sequence (FSPS) by compound-class 14C dating. Our results show varying age offsets between the formation and sedimentation of leaf wax n-alkanes from well-developed (paleo)soils and fluvial sediments that are mostly due to their complex origin in such sequences. Thus, dating the leaf wax n-alkanes is an important step for more robust leaf-wax-based paleoenvironmental reconstructions in FSPSs.

Recent technological advances allow researchers to obtain radiocarbon ages from smaller samples than previously possible. We investigate the reliability and precision of radiocarbon ages obtained from miniature (11–150 μg C) samples of terrestrial plant fragments taken from sediment cores from Lake Żabińskie, Poland. We further investigate how sampling density (the number of ages per 1000 years) and sample mass (which is related to age precision) influence the performance of age–depth models.

We present leaf wax n-alkanes and their compound-specific (CS) δ13C isotopes from semi-arid and/or arid Mongolia to test their potential for paleoenvironmental reconstructions. Plants and topsoils were analysed and checked for climatic control. Chain-length variations are distinct between grasses and Caragana, which are not biased by climate. However CS δ13C is strongly correlated to climate, so n-alkanes and their CS δ13C show great potential for paleoenvironmental reconstruction in Mongolia.

Chemotaxonomic identification of keystone plant species in the Bale Mountains are possible using lignin phenols. However, Erica could not be differentiated chemotaxonomically from all other investigated plants using n-alkanes. Unambiguous characteristic patterns of lignin phenols reflected in the plant samples were not sustained in the organic layers and mineral topsoils. This is due to degradation and organic matter inputs by roots. Therefore, the past extent of Erica is still speculative.

The study evaluates the ability of stable isotopes (δ13C and δ15N) and sugar biomarkers to distinguish Erica from the dominant vegetation of the Bale Mountains in order to reconstruct the past extent of Erica on the Sanetti Plateau. No significant differences in stable isotopes are found between the dominant plant species. Although Erica is characterized by quite high (G+M)/(A+X) ratios, it cannot be unambiguously distinguished from other plants due to degradation and soil microbial effects.

Carbonaceous aerosols from natural sources were abundant regardless of season. Residential wood burning (RWB) emissions were occasionally equally as large as or larger than of fossil-fuel sources, depending on season and region. RWB emissions are poorly constrained; thus emissions inventories need improvement. Harmonizing emission factors between countries is likely the most important step to improve model calculations for biomass burning emissions and European PM2.5 concentrations in general.

In this study, we systematically analyze leaf wax derived n-alkane patterns in eastern Georgia to test their potential for paleoenvironmental reconstructions in the semi-humid to semi-arid central southern Caucasus region. We investigated the influence of vegetation types on the leaf wax signal in modern plants and topsoil material. Our results show distinct and systematic differences in the n-alkane patterns between vegetation types and prove their potential for vegetation reconstructions.

In this work, four schemes for the simulation of organic aerosols in the western Mediterranean basin are added to the CHIMERE chemistry–transport model; the resulting simulations are then compared to measurements obtained from ChArMEx. It is concluded that the scheme taking into account the fragmentation and the formation of nonvolatile organic aerosols corresponds better to measurements; the major source of this aerosol in the western Mediterranean is found to be of biogenic origin.

Here we present a quantitative source apportionment of WSOC, isolated from aerosols in China using radiocarbon (14C) and offline high-resolution time of flight aerosol mass spectrometer measurements. We demonstrate a dominant contribution of non-fossil emissions to WSOC aerosols in the Northern Hemisphere. However, the fossil fraction is substantially larger in aerosols from East Asia and the east Asian pollution outflow, especially during winter, due to increasing coal combustion.

A novel offline LDI-MS method was developed to analyse particulate matter (PM) collected at multiple sites in central Europe during the entire year of 2013. PM sources were identified by positive matrix factorization. Wood burning emissions were separated according to the burning conditions; inefficient burns had a larger impact on air quality in southern Alpine valleys than in northern Switzerland. Moreover, primary tailpipe exhaust was distinguished from aged/secondary traffic emissions.

Fossil fuel CO2 is the major contributor of anthropogenic CO2 in the atmosphere, and accurate quantification is essential to better understand the carbon cycle. Such accurate quantification can be conducted based on radiocarbon measurements. In this study, we present radiocarbon measurements from a tall tower site in Switzerland. From these measurements, we have observed seasonally varying fossil fuel CO2 contributions and a biospheric CO2 component that varies diurnally and seasonally.

Airborne particulate matter (PM) negatively impacts air quality in cities throughout the world. An important fraction of PM is organic aerosol. We have evaluated and developed several new models for secondary organic aerosol (SOA), which is formed from the chemical processing of gaseous precursors. Using our model results, we have quantified important SOA sources and precursors and also identified possible model parameterizations that could be used for air quality predictions.

The ChArMEx SOP2 field campaign took place from 15 July to 5 August 2013 in the western Mediterranean Basin at Ersa, a remote site in Cape Corse. Exhaustive descriptions of the chemical composition of air masses in gas and aerosol phase were performed. An analysis of these measurements was performed using various source-receptor approaches. This led to the identification of several factors linked to primary sources but also to secondary processes of both biogenic and anthropogenic origin.

At catchment scale, it is challenging to provide the required input parameters for physically based slope stability models. In the present study, the parameterization of such a model is optimized against observed shallow landslides during two triggering rainfall events. With the resulting set of parameters the model reproduces the location and the triggering timing of most observed landslides. Based on that, potential effects of increasing precipitation intensity on slope stability are assessed.

The Arctic Ocean, especially the Siberian shelves, overlays large areas of subsea permafrost that is degrading. We show that methane with a biogenic origin is emitted from this permafrost. At locations where bubble plumes have been observed, methane can escape oxidation in the surface sediment and rapidly migrate through the very shallow water column of this region to escape to the atmosphere, generating a positive radiative feedback.

Most studies use a single Ångström exponent for wood burning (αWB) and traffic (αTR) emissions in the Aethalometer model, used for source apportionment of black carbon, derived from previous work. However, accurate determination of the α values is currently lacking. Comparing radiocarbon measurements (14C) with the Aehtalometer model, good agreement was found, indicating that the Aethalometer model reproduces reasonably well the 14C results using our best estimate of a single αWB and αTR.

Measurements of the radioactive carbon isotope 14C allow to identify the sources of aerosol carbon. We report an extensive 14C source apportionment record in the Netherlands with samples covering a whole year. We discovered that long-range transport has a large influence on aerosol carbon levels. Fossil fuel carbon is least influenced by long-range transport and more regional in origin. Biomass burning seems to be a minor source of aerosol carbon in the Netherlands.

A meaningful interpretation of the climatic history contained in ice cores requires a precise chronology. For dating the older and deeper part of the glaciers, radiocarbon analysis can be used when organic matter such as plant or insect fragments are found in the ice. Since this happens rarely, a complementary dating tool, based on radiocarbon dating of the insoluble fraction of carbonaceous aerosols entrapped in the ice, allows for ice dating between 200 and more than 10 000 years.

In comparison with the results during summer in Lanzhou, the air pollution during winter was more severe and the sources were more complex. In addition, this paper estimates the contributions of fossil and non-fossil sources of organic carbon to primary and secondary organic carbon using the carbon isotopic method.

Many Chinese cities now are suffering the high loadings of fine particular matters, which can bring a lot of negative impacts on air quality, human health, and the climate system. The Chinese government generally focuses on the control of the emissions from vehicles and industry. Our results evidently show that the burning of biomass materials such as wood and agricultural residues can lead to the urban air pollution in China. The characteristic of haze covering China is distinct from regions.

We describe a stepwise uncertainty analysis of 14C measurements of organic (OC) and elemental (EC) carbon fractions of aerosols. Using the Swiss_4S thermal-optical protocol with a newly established trapping setup, we show that we can efficiently isolate and trap each carbon fraction and perform 14C analysis of ultra-small OC and EC samples with high accuracy and low 14C blanks. Our study presents a first step towards the development of a common protocol for OC and EC 14C measurements.

Stable water isotopes (18O/16O and 2H/1H) are invaluable proxies for paleoclimate research. Here we use a coupled 18O/16O and 2H/1H biomarker approach based on plant-derived sugars and n-alkanes. Applying this innovative approach to a topsoil transect allows for (i) calculating the deuterium-excess of leaf water as a proxy for relative humidity and (ii) calculating the plant source water isotopic composition (~precipitation). The approach is validated by the presented climate transect results.

Stable carbon isotopes, radiocarbon ages and ash content confirm peat growth in the near-natural bog but also indicate previous degradation. When the bog is managed extensively or intensively as grassland, all parameters indicate degradation and substantial C loss of the order of 18.8 to 42.9 kg C m-2.

Wood is a renewable fuel but its combustion for residential heating releases a number of locally acting air pollutants, most notably particulate matter known to have adverse effects on human health. This paper used chemical tracers for wood smoke to estimate the contribution that burning wood makes to concentrations of airborne particles in the atmosphere of southern England and most particularly in London.

Source apportionment of fine carbonaceous aerosols using radiocarbon and other organic markers measurements during 2013 winter haze episodes was conducted at four megacities in China. Our results demonstrate that fossil emissions predominate EC with a mean contribution of 75±8%, whereas non-fossil sources account for 55±10% of OC; and the increment of TC on heavily polluted days was mainly driven by the increase of secondary OC from both fossil-fuel and non-fossil emissions.

Human intervention in the natural drainage system of the Hessische Ried (Germany) resulted in the transformation of a large wetland into a cultural landscape. In this study, we reconstruct the river network that was used by Romans for transportation and security. We found that the Romans collected water from several smaller rivers to establish the river Landgraben as a navigable waterway. Unexpectedly, larger rivers did not contribute any water to the Landgraben system during Roman times.

The study of past environmental changes and their effects on cultures provides key information to reconstruct human–environmental interactions and model how climate change affects cultures and possible avenues of future adaptation. The Shiraki Plain is an uninhabited plain largely devoid of water resources. However, traces of extensive Bronze Age civilization with complex social organization were revealed, featuring the typology of settlements, their ages, and spatial planning.

Geoarchaeological research in ancient Bubastis has concentrated on the western and central parts of the city. Although the “Temple of Hermes” was investigated and roughly located in eastern Bubastis during exploratory excavations in the 19th century, no traces of the temple can be seen on the surface today. Geomorphological surveys carried out in 2023 to determine the possible location of the temple revealed a central area of elevated sandy deposits, providing a suitable area for the building.

Research in loess landscapes provides evidence for the paleoenvironmental settings for past human societies and for the paleoclimate evolution of the past. Archeological and geoscientific investigations must consider different relief settings due to erosion, slope wash, accumulation of sediments and relocation of artifacts. The Lower Rhine Embayment can serve as a blueprint for such research as a typical loess landscape of Central Europe.

Our results indicate that the soils around Munigua currently have the potential for at least limited agricultural use in larger areas and would certainly allow the production of basic agricultural goods, not only today but most likely also in Roman times. Multi-layered colluvial deposits. as well as an excavated Roman hortic Anthrosol, indicate a long-term agrarian utilization of the area. Based on these results we can conclude that the city's economy was by no means focused solely on mining.

Geophysical and archaeological work at Sais (Sa el-Hagar, Egypt) is analysed to discuss the relationships between the palaeolandscape, the evolving river and floodplain and human cultural activity at the site, where humans have lived since Neolithic times (4000 Before Common Era) until the present. The results show a close correlation with and reliance on the underlying sandhills for settlement and the way in which human activity has subsequently affected the floodplain landscape at the site.

Lake Mareotis (NW Nile delta, Egypt) was a gateway between the Nile valley and the Mediterranean during Greco-Roman times. The hydrological evolution of Lake Mareotis was reconstructed using lake sediments and archaeological archives. The data show both a rise in Nile inputs to the basin during the first millennia BC and AD and a lake-level rise of ca. 1.5 m during the Roman period. A high-energy deposit such as a tsunami also possibly affected Alexandria's lacustrine hinterland.

At Buto, Sais and Bubastis in the Nile delta, temples were built on gentle rising mounds surrounded by canals and lakes, representing a perfect fusion of natural and sacred landscapes. The waters served cultic purposes and played an important role in local mythological traditions. The paper aims to reconstruct those sacred waterways, canals and marshes according to recent geoarchaeological and philological research and to assess their impact on the evolution of key mythological narratives.

Based on a new method, this paper proves the presence of several lakes during Greco-Roman antiquity in the Mariut basin and the digging of a canal network (up to 12 km long) in the Roman period to link them to Lake Mareotis. This challenges a 2-century-long scientific tradition according to which Lake Mareotis naturally linked Taposiris Magna to Alexandria during the Hellenistic and Roman periods. It is thus a starting point for new analyses of regional archaeology and geoarchaeology.

The contribution highlights the use of Landsat archive data (1985–2019) for the detection of surface anomalies potentially related to buried near-surface paleogeomorphological deposits in the Nile Delta (Egypt). The analyses of selected spectral-temporal metrics showed several anomalies in the immediate surroundings of Pleistocene sand hills (geziras) and settlement mounds (tells) of the eastern Delta, which allowed mapping of the potential near-surface continuation.

This study combines geomorphological–hydrological analyses with the distribution of archaeological sites and obsidian raw material outcrops within the catchment of the Bisare River, Mt Damota, and Mt Sodicho (southwestern Ethiopian Highlands). The current highly dynamic hydrological system, strong recent sediment erosion, and increased human impact lead to land degradation, resulting in exposure of lithic raw material outcrops and destruction of archaeological material.

It was possible to define the turning point from extremely clayey and organic- rich sedimentation in the Early and Middle Holocene towards the deposition of coarser-grained and less organic overbank fines in the lower Pleiße valley near Leipzig, NW Saxony. This change occurred between 4000 and 3300 BCE more than 1000 years after the beginning of Early Neolithic settlement and was obviously linked with land clearance by the first farmers.

This study investigates Neolithic settlement dynamics by combining archaeological source criticism and archaeopedological data from colluvial deposits. It is shown that the distribution of Neolithic sites in the Baar region is distorted by superimposition due to erosion. Furthermore, the preservation conditions for pottery are limited by weathering effects. By complementing archaeological data with phases of colluviation we are able to point out settlement dynamics throughout the Neolithic.

This case study provides a reconstruction of settlement and land-use history since the 13th century CE in a small valley in the Ore Mountains (Saxony). Archaeological evidence shows settlement activities with a strong building and mining activities that also triggered local soil erosion. After the abandonment of the site in the middle of the 15th century CE and a reafforestation, later land use in the area occurred in the form of charcoal production.

Provided here are novel data concerning site formation processes and Middle Palaeolithic human presence at Cotencher cave (Switzerland). A local glaciation around 70 ka was followed by ice-free conditions, when artefacts and faunal remains were displaced by solifluction processes. Evidence of local glacier development around 36 ka is also presented. This interdisciplinary study contributes new elements for the understanding of climatic changes and human passage in the central Jura Mountains.
