However, recent advances in numerical modelling have shed new light on the precise interaction of marine ice sheets with the change in near-field sea level, and the related stability of the grounding line position. Studies using fully coupled ice-sheet – sea-level models have shown that accounting for gravitationally self-consistent sea-level change will act to slow down the retreat and advance of marine ice-sheet grounding lines. Moreover, by simultaneously solving the ’sea-level equation’ and modelling ice-sheet flow, coupled models provide a global field of relative sea-level change that is consistent with dynamic changes in ice-sheet extent. In this paper we present an overview of recent advances, possible caveats, methodologies and challenges involved in coupled ice-sheet – sea-level modelling. We conclude by presenting a first-order comparison between a suite of relative sea-level data and output from a coupled ice-sheet – sea-level model.

H.; Gosling, W. D.; Rodbell, D. T.; Wagner-Cremer, F.; Donders, T. H.; Coastal dynamics, Fluvial systems and Global change; Palaeo-ecologie;The biodiverse montane forests of the tropical Andes are today frequently disturbed by rainfall-driven mass movements which occur mostly during extreme El Niño events. Over the coming decades these events are projected to double under the 1.5 °C global warming scenario. The consequent increased rainfall and mass movement events likely present an elevated risk to millions of people living in the Andes. However, the impact of more frequent rainfall extremes remains unclear due to a lack of studies that directly link past changes in El Niño-Southern Oscillation (ENSO) frequency to forest and landscape disturbance patterns. Here, we present the first Holocene palaeoecological record from Laguna Pallcacocha, southern Ecuador, a key site for El Niño reconstructions. We demonstrate that for the past 10,000 years plant taxa indicative of recolonization – such as Alnus acuminata – covary with El Niño-induced flood layers in the lake. An amplified forest disturbance pattern is observed in the late Holocene, suggesting enhanced slope instability following deforestation. The temporal pattern is not explained by tree line fluctuations or human impact, while the latter does amplify the impact of ENSO on landscape disturbance. Spatial correlations between modern ENSO and precipitation are consistent with a regional comparison of Holocene records of landscape disturbance. Our results indicate that climate extremes, such as those associated with future intensification of El Niño, combined with ongoing land use change will increase the frequency of mass movements elevating risks for millions of people in the Andes.

The stable carbon isotope ratio (δ13C value) of Daphnia spp. resting egg shells (ephippia) provides information on past changes in Daphnia diet. Measurements are typically performed on samples of ≥20 ephippia, which obscures the range of values associated with individual ephippia. Using a recently developed laser ablation-based technique, we perform multiple δ13C analyses on individual ephippia, which show a high degree of reproducibility (standard deviations 0.1–0.5‰). We further measured δ13C values of 13 ephippia from surface sediments of three Swiss lakes. In the well-oxygenated lake with low methane concentrations, δ13C values are close to values typical for algae (−31.4‰) and the range in values is relatively small (5.8‰). This variability is likely driven by seasonal (or inter-annual) variability in algae δ13C values. In two seasonally anoxic lakes with higher methane concentrations, average values were lower (−41.4 and −43.9‰, respectively) and the ranges much larger (10.7 and 20.0‰). We attribute this variability to seasonal variation in incorporation of methane-derived carbon. In one lake we identify two statistically distinct isotopic populations, which may reflect separate production peaks. The potentially large within-sample variability should be considered when interpreting small-amplitude, short-lived isotope excursions based on samples consisting of few ephippia. We show that measurements on single ephippia can be performed using laser ablation, which allows for refined assessments of past Daphnia diet and carbon cycling in lake food webs. Furthermore, our study provides a basis for similar measurements on other chitinous remains (e.g. from chironomids, bryozoans). peerReviewed

Isoprenoid glycerol dialkyl glycerol tetraethers (isoGDGTs) are membrane lipids of Archaea. Organic biomarker proxies associated with these lipids, such as the TEX 86 paleothermometer and Branched and Isoprenoid Tetraether (BIT) index, are often used in paleoenvironmental reconstructions for the marine environment, but their general applicability in lacustrine settings is hampered by limited understanding of the biological sources and environmental drivers influencing isoGDGT production. To validate the use of isoGDGT proxies in lakes, we studied the occurrence of isoGDGTs in Lake Chala, a permanently stratified (meromictic) crater lake in equatorial East Africa. We analyzed the abundance and distribution of isoGDGTs in 17 depth profiles of suspended particulate matter (SPM) collected monthly between September 2013 and January 2015, and compared this with the abundance and composition of archaea based on 16S rRNA gene and quantitative PCR analysis. Both isoGDGTs and archaeal abundance in the SPM were exceptionally low throughout the study period. In the oxygenated part of the water column, higher fractional abundances of crenarchaeol are matched by a predominance of the ammonia-oxidizing Thaumarchaeota I.1b that are known to produce this GDGT, whereas deep anoxic water layers are characterized by high fractional abundances of GDGT-0 as well as the anaerobic heterotrophic Group C3 MCG Bathyarchaea and specific euryarchaeotal methanogens. Analysis of intact polar lipid (IPL) isoGDGTs using SPM depth profiles from three months representing distinct seasons during the study period revealed the presence of several IPLs of GDGT-0 in the anoxic lower water column, which are rarely found in natural settings. IPL GDGT-0 with a phosphatidylglycerol (PG-), monohexosephosphatidylglycerol (MH-PG-) and dihexose-phosphatidylglycerol (DH-PG-) head-group was typically only present just above the lake bottom at 90 m depth and probably reflect specific communities of anaerobic archaea. We also determined the flux and distribution of isoGDGTs in settling particles collected monthly between November 2006 and January 2015 from a sediment trap suspended at 35 m water depth to assess seasonal and inter-annual variability in surface-water isoGDGT production, and compared this with the temporal distribution of isoGDGTs in the 25,000-year long sediment record from Lake Chala. Monthly variation of isoGDGTs in the 98-month settling-particles record did not show a strong annual pattern related to seasonal water-column mixing and stratification, likely because the oxycline was regularly situated below sediment-trap depth. Episodes of high GDGT-0 concentrations relative to crenarchaeol in the settling particles can therefore be linked to periods of exceptionally shallow oxycline depth, which suppresses the thaumarchaeotal bloom. During such intervals, TEX86 based paleotemperatures are not reliable because isoGDGT input from other archaeal sources disproportionally influences TEX86 values and creates a cold-temperature bias. Additionally, the abundance of the crenarchaeol isomer relative to crenarchaeol (f[CREN]) gradually increases during such episodes of high GDGT-0/crenarchaeol ratio, suggesting increasing dominance of Group I.1b over Group I.1a Thaumarchaeota, and might prove a good marker for prolonged shallow-oxycline conditions. Most importantly, the associated near-absence of crenarchaeol during times of strong upper-water-column stratification results in high BIT-index values. We propose that this suppression mechanism may be the principal driver of BIT-index variation in the sediment record of Lake Chala, and the main source of observed congruence between the BIT index and climate-driven lake-level variation on long time scales.

A multi-proxy reconstruction of a sediment core from the Tatos basin in the Mauritian lowlands reveals a dynamic environmental history during the last 8000 years. Under influence of sea level rise, the basin progressed from a wetland to a shallow lake between 8000 and 2500 cal yr BP and it slowly changed back into a wetland after sea level reached its highest position at around 2500 cal yr BP. The groundwater level in the basin was strongly affected by sea level rise and precipitation-forced runoff through the porous volcanic bedrock.Millennial-scale precipitation changes in the Mauritian lowlands were derived from the pollen records of semi-dry forest and palm woodland. Salinity and environmental reconstructions based on diatoms, ostracods, stable isotopes and sediment composition showed numerous decadal and centennial droughts and wet events. Mauritius experienced wet conditions between similar to 8000 and similar to 6800 cal yr BP, followed by decreasing humidity from 6800 to 6000 cal yr BP. Dry conditions persisted until similar to 1200 cal yr BP, after which wetter conditions have prevailed as recorded from Mauritian lowland and upland records. Climate dynamics reflects northern hemisphere monsoon activity and suggest that Mauritian rainfall and the Indian and Asian summer monsoons are linked, as both receive moisture from the southern equatorial Indian Ocean.The anti-phased relationship of climate dynamics between the Mauritian lowlands and western tropical Australia during the middle Holocene is interpreted as a prolonged configuration of a negative mode of the Indian Ocean Dipole OM. A negative IOD-like state is supported by decreased Asian summer monsoon rainfall, higher Austral-Indonesian summer monsoon rainfall and lower temperatures in the Kilimanjaro record. Conversely, repeated decadal-scale wet events in the Mauritian lowlands occurring every similar to 350 years reflect short positive IOD-like events.The onset of ENSO climate variability followed an anomalously strong negative 100-like event and shifted teleconnections from the tropical Indian Ocean to the Pacific Ocean. A shift in ENSO activity around similar to 2600 cal yr BP signifies the decoupling of ENSO from the Atlantic ITCZ. Subsequently, the influence of ENSO on climate in the western Indian Ocean is indicated by increased storm frequency and drought events after 2660 cal yr BP in Mauritius and reduced monsoon activity in the western and eastern Indian Ocean.

Abstract Benthic oxygen isotope records of deep marine sedimentary archives have yielded a wealth of information regarding ice sheet dynamics and climate change during the Pleistocene. However, since they often lack independent age control, these records are generally bound by a fixed phase relationship between orbital forcing and the climate response, e.g. ice volume changes. We present the first long (∼1.2 Ma) benthic oxygen isotope record from the eastern Mediterranean, based on ODP Sites 967 and 968, which clearly reflects the behavior of global climate on a glacial–interglacial scale throughout the late Pleistocene time period. The age model for our record is based on tuning the elemental ratio of titanium versus aluminum (Ti/Al) against insolation. The Ti/Al record is dominated by the precession-related changes in northern African climate, i.e. monsoonal forcing, and hence largely independent of glacial–interglacial variability. We found the largest offset between our chronology and that of the widely applied, open ocean stacked record LR04 (Lisiecki and Raymo, 2005) for T VII (∼624 ka), which occurred ∼9 kyr earlier according to our estimates, though in agreement with the AICC2012 δD ice chronology of EPICA Dome C (Bazin et al., 2013). Spectral cross-correlation analysis between our benthic δ 18 O record and 65°N summer insolation reveals significant amounts of power in the obliquity and precession range, with an average lag of 5.5 ± 0.8 kyr for obliquity, and 6.0 ± 1.0 kyr for precession. In addition, our results show that the obliquity-related time lag was smaller (3.0 ± 3.3 kyr) prior to ∼900 ka than after (5.7 ± 1.1 kyr), suggesting that on average the glacial response time to obliquity forcing increased during the mid-Pleistocene transition, much later than assumed by Lisiecki and Raymo (2005). Finally, we found that almost all glacial terminations have a consistent phase relationship of ∼45 ± 45° with respect to the precession and obliquity-driven increases in 65°N summer insolation, consistent with the general consensus that both obliquity and precession are important for deglaciation during the Late Pleistocene. Exceptions are glacial terminations T IIIb , T 36 and potentially T 32 (and T VII T 24 and T 34 ), which show this consistent phase relationship only with precession (only with obliquity). Our findings point towards an early (>1200 ka) onset of the Mid Pleistocene Transition. Vice versa, the timing of T VII , which can only be explained as a response to obliquity forcing, indicates that the transition lasted until at least after MIS 15.

However, recent advances in numerical modelling have shed new light on the precise interaction of marine ice sheets with the change in near-field sea level, and the related stability of the grounding line position. Studies using fully coupled ice-sheet – sea-level models have shown that accounting for gravitationally self-consistent sea-level change will act to slow down the retreat and advance of marine ice-sheet grounding lines. Moreover, by simultaneously solving the ’sea-level equation’ and modelling ice-sheet flow, coupled models provide a global field of relative sea-level change that is consistent with dynamic changes in ice-sheet extent. In this paper we present an overview of recent advances, possible caveats, methodologies and challenges involved in coupled ice-sheet – sea-level modelling. We conclude by presenting a first-order comparison between a suite of relative sea-level data and output from a coupled ice-sheet – sea-level model.

H.; Gosling, W. D.; Rodbell, D. T.; Wagner-Cremer, F.; Donders, T. H.; Coastal dynamics, Fluvial systems and Global change; Palaeo-ecologie;The biodiverse montane forests of the tropical Andes are today frequently disturbed by rainfall-driven mass movements which occur mostly during extreme El Niño events. Over the coming decades these events are projected to double under the 1.5 °C global warming scenario. The consequent increased rainfall and mass movement events likely present an elevated risk to millions of people living in the Andes. However, the impact of more frequent rainfall extremes remains unclear due to a lack of studies that directly link past changes in El Niño-Southern Oscillation (ENSO) frequency to forest and landscape disturbance patterns. Here, we present the first Holocene palaeoecological record from Laguna Pallcacocha, southern Ecuador, a key site for El Niño reconstructions. We demonstrate that for the past 10,000 years plant taxa indicative of recolonization – such as Alnus acuminata – covary with El Niño-induced flood layers in the lake. An amplified forest disturbance pattern is observed in the late Holocene, suggesting enhanced slope instability following deforestation. The temporal pattern is not explained by tree line fluctuations or human impact, while the latter does amplify the impact of ENSO on landscape disturbance. Spatial correlations between modern ENSO and precipitation are consistent with a regional comparison of Holocene records of landscape disturbance. Our results indicate that climate extremes, such as those associated with future intensification of El Niño, combined with ongoing land use change will increase the frequency of mass movements elevating risks for millions of people in the Andes.

The stable carbon isotope ratio (δ13C value) of Daphnia spp. resting egg shells (ephippia) provides information on past changes in Daphnia diet. Measurements are typically performed on samples of ≥20 ephippia, which obscures the range of values associated with individual ephippia. Using a recently developed laser ablation-based technique, we perform multiple δ13C analyses on individual ephippia, which show a high degree of reproducibility (standard deviations 0.1–0.5‰). We further measured δ13C values of 13 ephippia from surface sediments of three Swiss lakes. In the well-oxygenated lake with low methane concentrations, δ13C values are close to values typical for algae (−31.4‰) and the range in values is relatively small (5.8‰). This variability is likely driven by seasonal (or inter-annual) variability in algae δ13C values. In two seasonally anoxic lakes with higher methane concentrations, average values were lower (−41.4 and −43.9‰, respectively) and the ranges much larger (10.7 and 20.0‰). We attribute this variability to seasonal variation in incorporation of methane-derived carbon. In one lake we identify two statistically distinct isotopic populations, which may reflect separate production peaks. The potentially large within-sample variability should be considered when interpreting small-amplitude, short-lived isotope excursions based on samples consisting of few ephippia. We show that measurements on single ephippia can be performed using laser ablation, which allows for refined assessments of past Daphnia diet and carbon cycling in lake food webs. Furthermore, our study provides a basis for similar measurements on other chitinous remains (e.g. from chironomids, bryozoans). peerReviewed

Isoprenoid glycerol dialkyl glycerol tetraethers (isoGDGTs) are membrane lipids of Archaea. Organic biomarker proxies associated with these lipids, such as the TEX 86 paleothermometer and Branched and Isoprenoid Tetraether (BIT) index, are often used in paleoenvironmental reconstructions for the marine environment, but their general applicability in lacustrine settings is hampered by limited understanding of the biological sources and environmental drivers influencing isoGDGT production. To validate the use of isoGDGT proxies in lakes, we studied the occurrence of isoGDGTs in Lake Chala, a permanently stratified (meromictic) crater lake in equatorial East Africa. We analyzed the abundance and distribution of isoGDGTs in 17 depth profiles of suspended particulate matter (SPM) collected monthly between September 2013 and January 2015, and compared this with the abundance and composition of archaea based on 16S rRNA gene and quantitative PCR analysis. Both isoGDGTs and archaeal abundance in the SPM were exceptionally low throughout the study period. In the oxygenated part of the water column, higher fractional abundances of crenarchaeol are matched by a predominance of the ammonia-oxidizing Thaumarchaeota I.1b that are known to produce this GDGT, whereas deep anoxic water layers are characterized by high fractional abundances of GDGT-0 as well as the anaerobic heterotrophic Group C3 MCG Bathyarchaea and specific euryarchaeotal methanogens. Analysis of intact polar lipid (IPL) isoGDGTs using SPM depth profiles from three months representing distinct seasons during the study period revealed the presence of several IPLs of GDGT-0 in the anoxic lower water column, which are rarely found in natural settings. IPL GDGT-0 with a phosphatidylglycerol (PG-), monohexosephosphatidylglycerol (MH-PG-) and dihexose-phosphatidylglycerol (DH-PG-) head-group was typically only present just above the lake bottom at 90 m depth and probably reflect specific communities of anaerobic archaea. We also determined the flux and distribution of isoGDGTs in settling particles collected monthly between November 2006 and January 2015 from a sediment trap suspended at 35 m water depth to assess seasonal and inter-annual variability in surface-water isoGDGT production, and compared this with the temporal distribution of isoGDGTs in the 25,000-year long sediment record from Lake Chala. Monthly variation of isoGDGTs in the 98-month settling-particles record did not show a strong annual pattern related to seasonal water-column mixing and stratification, likely because the oxycline was regularly situated below sediment-trap depth. Episodes of high GDGT-0 concentrations relative to crenarchaeol in the settling particles can therefore be linked to periods of exceptionally shallow oxycline depth, which suppresses the thaumarchaeotal bloom. During such intervals, TEX86 based paleotemperatures are not reliable because isoGDGT input from other archaeal sources disproportionally influences TEX86 values and creates a cold-temperature bias. Additionally, the abundance of the crenarchaeol isomer relative to crenarchaeol (f[CREN]) gradually increases during such episodes of high GDGT-0/crenarchaeol ratio, suggesting increasing dominance of Group I.1b over Group I.1a Thaumarchaeota, and might prove a good marker for prolonged shallow-oxycline conditions. Most importantly, the associated near-absence of crenarchaeol during times of strong upper-water-column stratification results in high BIT-index values. We propose that this suppression mechanism may be the principal driver of BIT-index variation in the sediment record of Lake Chala, and the main source of observed congruence between the BIT index and climate-driven lake-level variation on long time scales.

A multi-proxy reconstruction of a sediment core from the Tatos basin in the Mauritian lowlands reveals a dynamic environmental history during the last 8000 years. Under influence of sea level rise, the basin progressed from a wetland to a shallow lake between 8000 and 2500 cal yr BP and it slowly changed back into a wetland after sea level reached its highest position at around 2500 cal yr BP. The groundwater level in the basin was strongly affected by sea level rise and precipitation-forced runoff through the porous volcanic bedrock.Millennial-scale precipitation changes in the Mauritian lowlands were derived from the pollen records of semi-dry forest and palm woodland. Salinity and environmental reconstructions based on diatoms, ostracods, stable isotopes and sediment composition showed numerous decadal and centennial droughts and wet events. Mauritius experienced wet conditions between similar to 8000 and similar to 6800 cal yr BP, followed by decreasing humidity from 6800 to 6000 cal yr BP. Dry conditions persisted until similar to 1200 cal yr BP, after which wetter conditions have prevailed as recorded from Mauritian lowland and upland records. Climate dynamics reflects northern hemisphere monsoon activity and suggest that Mauritian rainfall and the Indian and Asian summer monsoons are linked, as both receive moisture from the southern equatorial Indian Ocean.The anti-phased relationship of climate dynamics between the Mauritian lowlands and western tropical Australia during the middle Holocene is interpreted as a prolonged configuration of a negative mode of the Indian Ocean Dipole OM. A negative IOD-like state is supported by decreased Asian summer monsoon rainfall, higher Austral-Indonesian summer monsoon rainfall and lower temperatures in the Kilimanjaro record. Conversely, repeated decadal-scale wet events in the Mauritian lowlands occurring every similar to 350 years reflect short positive IOD-like events.The onset of ENSO climate variability followed an anomalously strong negative 100-like event and shifted teleconnections from the tropical Indian Ocean to the Pacific Ocean. A shift in ENSO activity around similar to 2600 cal yr BP signifies the decoupling of ENSO from the Atlantic ITCZ. Subsequently, the influence of ENSO on climate in the western Indian Ocean is indicated by increased storm frequency and drought events after 2660 cal yr BP in Mauritius and reduced monsoon activity in the western and eastern Indian Ocean.

Abstract Benthic oxygen isotope records of deep marine sedimentary archives have yielded a wealth of information regarding ice sheet dynamics and climate change during the Pleistocene. However, since they often lack independent age control, these records are generally bound by a fixed phase relationship between orbital forcing and the climate response, e.g. ice volume changes. We present the first long (∼1.2 Ma) benthic oxygen isotope record from the eastern Mediterranean, based on ODP Sites 967 and 968, which clearly reflects the behavior of global climate on a glacial–interglacial scale throughout the late Pleistocene time period. The age model for our record is based on tuning the elemental ratio of titanium versus aluminum (Ti/Al) against insolation. The Ti/Al record is dominated by the precession-related changes in northern African climate, i.e. monsoonal forcing, and hence largely independent of glacial–interglacial variability. We found the largest offset between our chronology and that of the widely applied, open ocean stacked record LR04 (Lisiecki and Raymo, 2005) for T VII (∼624 ka), which occurred ∼9 kyr earlier according to our estimates, though in agreement with the AICC2012 δD ice chronology of EPICA Dome C (Bazin et al., 2013). Spectral cross-correlation analysis between our benthic δ 18 O record and 65°N summer insolation reveals significant amounts of power in the obliquity and precession range, with an average lag of 5.5 ± 0.8 kyr for obliquity, and 6.0 ± 1.0 kyr for precession. In addition, our results show that the obliquity-related time lag was smaller (3.0 ± 3.3 kyr) prior to ∼900 ka than after (5.7 ± 1.1 kyr), suggesting that on average the glacial response time to obliquity forcing increased during the mid-Pleistocene transition, much later than assumed by Lisiecki and Raymo (2005). Finally, we found that almost all glacial terminations have a consistent phase relationship of ∼45 ± 45° with respect to the precession and obliquity-driven increases in 65°N summer insolation, consistent with the general consensus that both obliquity and precession are important for deglaciation during the Late Pleistocene. Exceptions are glacial terminations T IIIb , T 36 and potentially T 32 (and T VII T 24 and T 34 ), which show this consistent phase relationship only with precession (only with obliquity). Our findings point towards an early (>1200 ka) onset of the Mid Pleistocene Transition. Vice versa, the timing of T VII , which can only be explained as a response to obliquity forcing, indicates that the transition lasted until at least after MIS 15.
