Competition between Diffusion and Fragmentation: An Important Evolutionary Process of Nature

, 2003
We investigate systems of nature where the common physical processes diffusion and fragmentation compete. We derive a rate equation for the size distribution of fragments.

Drilling the Marathousa palaeo‐lake in Greece (Peloponnese): inferring the environmental context of a Middle Pleistocene archaeological site

Boreas, EarlyView.
The Megalopolis Basin is located in the central Peloponnese (Greece), a region that is situated along one of the primary Pleistocene biogeographical corridors for intracontinental hominin migration. The basin comprises several hundred metres of Plio‐Pleistocene sediments alternating between clastics and lignites.

Luminescence dating of coastal deposits from the Chanthaburi Plain, Thailand

Boreas, EarlyView.
The ongoing global sea‐level rise urges us to better understand the dynamics of coastal processes for predicting future changes. Sedimentary deposits reflect past coastal environments but require precise chronological data to place evidence into a temporal context.

Weichselian history of the Fennoscandian Ice Sheet centre, Kvarken archipelago, western Finland—flow shifts, thermal regime and deglaciation

Boreas, EarlyView.
Rapid thaw of the Earth's cryosphere in response to anthropogenic warming highlights the need to identify and understand the contrasting signatures of past ice‐sheet stability and collapse. The Kvarken archipelago, western Finland, at the centre of the former Fennoscandian Ice Sheet (FIS), has been designated a UNESCO World Heritage site in recognition

Towards an ‘absolute’ timing of biostratigraphic and environmental phases from the Saalian late glacial to the Weichselian pleniglacial in central Europe—Insights from a lacustrine succession in Lichtenberg, northern Germany

Boreas, EarlyView.
Palynological records are central to the biostratigraphic subdivision of the Late Pleistocene in central Europe. Yet many interglacial and interstadial phases—such as the Eemian, Brörup and Odderade—remain only poorly constrained in time due to limited numerical dating.

Interaction of two tributary glacier branches and implications for surge behavior [PDF]

, 2018
Thesis (M.S.) University of Alaska Fairbanks, 2018A glacier surge is a dynamic phenomenon where the glacier after a long period of quiescence, increases its velocities by up to two orders of magnitude.

An overview of Mass Accumulation Rates in key Polish loess–palaeosol sequences derived from luminescence chronologies

Boreas, EarlyView.
Loess–palaeosol sequences (LPS) represent one of the most important continental archives of late Quaternary environmental change in Europe. Establishing reliable chronologies is essential for reconstructing dust dynamics and for correlating regional loess stratigraphies. In this study, we present the first systematically derived mass accumulation rate (

Control of Ocean Temperature on Jakobshavn Isbræ's Present and Future Mass Loss

Geophysical Research Letters, 2018
Large uncertainties in model parameterizations and input data sets make projections of future sea level rise contributions of outlet glaciers challenging.

Ice cores and SeaRISE: What we do (and don't) know [PDF]

Ice core analyses are needed in SeaRISE to learn what the West Antarctic ice sheet and other marine ice sheets were like in the past, what climate changes led to their present states, and how they behave.
