Solar modulation of flood frequency in central Europe during spring and summer on interannual to multi-centennial timescales [PDF]

open access: yesClimate of the Past, 2016
Solar influences on climate variability are one of the most controversially discussed topics in climate research. We analyze solar forcing of flood frequency in central Europe during spring and summer on interannual to multi-centennial timescales ...

Magnetostratigraphy of sediments from Lake El'gygytgyn ICDP Site 5011-1: paleomagnetic age constraints for the longest paleoclimate record from the continental Arctic [PDF]

open access: yesClimate of the Past, 2014
Paleomagnetic measurements were performed on sediments drilled from ICDP Site 5011-1 in Lake El'gygytgyn (67°30' N, 172°05' E) located in Far East Russian Arctic. The lake partly fills a crater formed by a meteorite impact 3.58 ± 0.04 Ma ago.

The unexpectedly short Holocene Humid Period in Northern Arabia

open access: yesCommunications Earth & Environment, 2022
The Holocene Humid Period in Northern Arabia may only have lasted for less than 1000 years and was characterised by substantial regional climatic variability, according to a high-resolution multi-proxy varved lake record from Tayma, Saudi Arabia.

Tracing rate and extent of human-induced hypoxia during the last 200 years in the mesotrophic lake, Tiefer See (NE Germany) [PDF]

open access: yesBiogeosciences
The global spread of lake hypoxia, [O2] < 2 mg L−1, during the last 2 centuries has had a severe impact on ecological systems and sedimentation processes. While the occurrence of hypoxia was observed in many lakes, a detailed quantification of hypoxia

European tree-ring isotopes indicate unusual recent hydroclimate

open access: yesCommunications Earth & Environment, 2023
The 2015–2018 summer drought event was unprecedented in Western and Central Europe over the last 400 years, whereas multi-year droughts were more frequent during the Maunder Minimum, according to a hydroclimate reconstruction using tree-ring stable ...

Winds From Massive Stars, And Implications for Supernovae and Gamma-Ray Bursts [PDF]

open access: yes, 2006
We review the effects of winds from massive O and B stars on the surrounding medium over the various stages of stellar evolution. Furthermore we discuss some of the implications for SNe and GRB evolution within this wind-blown medium.Comment: 6 pages, 1 ...

Microfluidic landscapes for evolution [PDF]

open access: yesCurrent Opinion in Chemical Biology, 2010
Evolution at its heart is an iterative algorithm composed of three steps: selection, amplification and mutagenesis. This algorithm can be applied to complex inputs such as populations of whole organisms and viruses, or mixtures of bare nucleic acids and proteins.
