“…Additionally, element intensities are not linearly related to element concentrations due to matrix effects that cause absorption and enhancement effects of the surrounding sediment (Weltje and Tjallingii, 2008;Weltje et al, 2015). However, centred log-ratio (clr) transformation (Aitchison, 1986) accounts for most of these effects (Weltje and Tjallingii, 2008), as well as circumventing complications of statistical analyses when using compositional data (Bertrand et al, 2023) and this approach has been applied to the geochemical record of Diss Mere.…”

Lake sediments are ideal archives to evaluate the interactions between climatically driven environmental responses and human activity on seasonal to multi‐decadal timescales. This study focuses on the unique sediments of Diss Mere, the only lake in England providing an annually laminated (varved) record for most of the Holocene. We combine microfacies analysis with X‐ray core scanning data to explore the influence of natural and human‐led changes on sediment deposition over the past 10 200 years and evaluate the sensitivity of the lake sediments to climate variability through time. Variability of titanium (Ti), calcium (Ca) and silica (Si) explain most of the lithological changes observed in the sediment and we identify three stages with low (10 290–2070 cal a bp), intermediate (2070–1040 cal a bp) and intensified (1040 cal a bp – present) human influence. During the first stage, where varved sediments are preserved, Ti is low due to the minimal detrital input into the lake. Ca and Si during this stage reveal high‐amplitude variability responding to seasonal changes in sediment deposition. The termination of varved sediment preservation and increases in sedimentation rates coincide with a major rise in Ti after this first stage, marking the intensification of human activity around the lake. Ca is used here as an indicator of temperature‐included calcite precipitation, and the long‐term variability of the Ca profile resembles Holocene temperature evolution. This continues during periods of intensified human activity, suggesting that the Diss Mere sediments remain sensitive to climate through time.

The stratigraphy and dating of lacustrine sediments and loess derivatives from Rodderberg, a crater of the East Eifel Volcanic Field in Germany, is based on luminescence dating and incorporates radiocarbon ages, fingerprinting of key tephra layers of the East Eifel Volcanic Field (Rieden Tephra, Hüttenberg Tephra, Laacher See Tephra), pollen stratigraphy, varve counting data, and a correlative age–depth model. These methods yield a robust age–depth model for the last 258 ka. Beyond this, luminescence ages differ from tephra‐derived ages. In light of the apparent presence of the Rieden Tephra, the lowermost interglacial is assigned to Marine Isotope Stage (MIS) 11 or 420 ka. This provides a high‐resolution record of environmental conditions representing an analogue for the Holocene, characterized by a warming planet. However, new luminescence ages may indicate a younger age for basal sediments, with the lowermost interglacial representing MIS 9. Both age–depth models constrain regional environmental changes during the Middle Pleistocene controlled by global climate variations. For the hydrologically closed nature of the Rodderberg crater, with limited pathways for sediment inflow and erosional export, these results shed new light on the continuity of long Middle Pleistocene records.
