Quantifying user variability in the traditional X‐ray ice‐rafted‐debris counting technique
Journal of Quaternary Science, EarlyView.ABSTRACT The flux of icebergs is most commonly constrained in the palaeo‐record by manually counting gravel clasts in sediment core X‐ray images—a trusted method in Quaternary science and palaeoceanography for nearly 40 years. In this study, we explore the reproducibility (user consistency and between‐user variability) of the traditional clast‐counting

Journal of Quaternary Science, EarlyView.ABSTRACT The timing and spatial patterns of glaciers retreat in the Northern French Alps during the Lateglacial (19.0–11.7 ka) remain debated, reflecting discrepancies among available chronological data sets. The complex interactions between major glaciers, such as the Rhône and Arve glaciers to the north and the Isère glacier to the south, represent a

Exploring Paleoclimatology in the Classroom
, 2009 This guide provides instructions for educators on how to access and use coral radioisotope data for classroom activities. The data consist of Sr/Ca ratios and Sea Surface Temperatures (SST) for coral samples near Rarotonga Island in the South Specific ...

Journal of Quaternary Science, EarlyView.ABSTRACT Glaciokarst landscapes pose distinctive challenges for cosmogenic dating because meltwater and runoff can be rapidly rerouted into ponors and conduit networks, weakening glacier–river coupling and promoting local sediment storage. We reconstruct glacier retreat and postglacial stabilization on the Snežnik Plateau (SW Slovenia) using in situ ...

Making palaeoclimatology research policy‐relevant: Insights and experience from the DECADAL Project
Journal of Quaternary Science, EarlyView.ABSTRACT Quaternary palaeoclimatology uniquely provides insights and new evidence about climate variability trends and extremes prior to the instrumental record; yet, its knowledge is rarely integrated into governmental decision‐making. This opinion piece shares lessons and experience from the UKRI‐funded DECADAL project, which bridges palaeoclimate ...

Journal of Quaternary Science, EarlyView.ABSTRACT Marine isotope substage 11c (~426–366 ka) is widely regarded as the most recent Pleistocene interglacial that is broadly analogous to the Holocene. The timing and magnitude of sea‐level changes during MIS 11 have been much debated, particularly concerning whether sea levels were significantly higher than during the Holocene. Empirical evidence

Paleoclimatology of Upper Triassic Playa Cycles. New Insights Into an Orbital Controlled Monsoon System (Norian, German Basin) [PDF]
, 2005 Paleoclimatology of Upper Triassic Playa Cycles: New Insights Into an Orbital Controlled Monsoon System (Norian, German Basin) Abstract The main purpose of the project was to study the rhythmic sediments of the Steinmergel Keuper playa system in the ...

Journal of Quaternary Science, EarlyView.ABSTRACT The Laurentide Ice Sheet covered vast areas of North America during the Wisconsinan, including the Labrador Shelf, off the coast of eastern Canada. The shelf is characterized by glacial cross‐shelf troughs, which have been considered as predominantly eroded by the last ice advance.
