Polar Research, 2020 Although the environmental factors influencing the growth rate and reproduction of benthic foraminifera are known, the relationship between foraminifera test size and environmental variables remains unclear, especially on geological timescales.

Glacial varves at the distal slope of Pandivere-Neva ice-recessional formations in western Estonia [PDF]
Bulletin of the Geological Society of Finland, 2012 The distribution and varve thickness data of Late Weichselian varved clay were analyzed to describe the proglacial sedimentary environment, ice recession and water-level changes in the Baltic Ice Lake at the distal position of Pandivere–Neva (13.5–13.1 ...

Timing of the Baltic Ice Lake in the eastern Baltic [PDF]
Bulletin of the Geological Society of Finland, 2013 A shoreline database for the Baltic, covering the Late Weichselian and Holocene, was compiled. The database includes about 1600 sites from Estonia, Latvia, Lithuania, Fin- land, NW Russia, Poland, Sweden and was used to create a GIS-based ...

On the deglaciation chronology of the Palivere ice-marginal zone, northern Estonia [PDF]
Bulletin of the Geological Society of Finland, 2012 This paper presents new bio-, litho- and chronostratigraphical evidence from two adjacent sediment sequences of the Tõdva and Saku basins, northern Estonia that refine the age estimate of the Palivere ice-marginal zone and the deglaciation history of ...

Journal of Maps, 2017 We present the first comprehensive glacial-landform map of the south Swedish uplands (SSU), deglaciated 15–13 ka ago, using one consistent method and dataset; a Light Detection and Ranging-derived digital elevation model.

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

Deglaciation-enhanced mantle CO2 fluxes at Yellowstone imply positive climate feedback
Nature CommunicationsMantle melt generation in response to glacial unloading has been linked to enhanced magmatic volatile release in Iceland and global eruptive records. It is unclear whether this process is important in systems lacking evidence of enhanced eruptions.

Environmental Research Letters, 2019 Carbon isotope minima were a ubiquitous feature in the mid-depth (1.5–2.5 km) Atlantic during Heinrich Stadial 1 (HS1, 14.5–17.5 kyr BP) and the Younger Dryas (YD, 11.6–12.9 kyr BP), with the most likely driver being collapse of the Atlantic Meridional ...
