Diatomite evidence for a small palaeo mountain lake at 3400 m asl, Lesotho, southern Africa

open access: yesJournal of Quaternary Science, Volume 40, Issue 3, Page 445-458, April 2025.
ABSTRACT The Eastern Lesotho Highlands experience an excess of rainfall sufficient to form the country's primary export, supplying the economic hub of southern Africa, Gauteng South Africa. However, there is currently only one natural lake in the country, Letšeng‐la Letsie, and evidence of palaeolakes in the region is therefore of particular interest ...

Universal breaking point asymptotic for energy spectrum of Riemann waves in weakly nonlinear non-dispersive media [PDF]

open access: yesarXiv, 2013
In this Letter we study the form of the energy spectrum of Riemann waves in weakly nonlinear non-dispersive media. For quadratic and cubic nonlinearity we demonstrate that the deformation of an Riemann wave over time yields an exponential energy spectrum which turns into power law asymptotic with the slope being approximately -8/3 at the last stage of ...

Consilience in practice: social–ecological dynamics of the Lake Volvi region (Greece) during the last two millennia

open access: yesJournal of Quaternary Science, Volume 40, Issue 3, Page 459-480, April 2025.
ABSTRACT The Lake Volvi area, part of the region of Macedonia (northern Greece), is a biodiversity hotspot, located in the central part of a major communication corridor connecting the western and eastern parts of the Balkans. The sediment succession from Lake Volvi is investigated here to provide a unique high‐resolution pollen and geochemical record ...

Land use, hydroclimate and damming influence organic carbon sedimentation in a flood pulse wetland, Malaysia

open access: yesJournal of Quaternary Science, Volume 40, Issue 4, Page 657-670, May 2025.
ABSTRACT Water bodies located in floodplains and tropical forests are known to be important carbon stores, but many are subjected to intensive pressures from damming, land use and climate changes. Sedimentary records preserve long‐term archives for understanding how such changes affect the quantity and quality of carbon stores.

Exploring soil erosion in the lake basins of Michoacán, Mexico: From sediment cores to conservation policies

open access: yesJournal of Quaternary Science, Volume 40, Issue 4, Page 671-683, May 2025.
ABSTRACT Understanding soil erosion, its history and links to potential drivers such as land use (particularly agriculture and deforestation), different cultural perspectives and climate change are crucial for the development of effective management and conservation strategies.

Double-Diffusive Convection [PDF]

open access: yesarXiv, 2014
Much progress has recently been made in understanding and quantifying vertical mixing induced by double-diffusive instabilities such as fingering convection (usually called thermohaline convection) and oscillatory double-diffusive convection (a process closely related to semiconvection).
