A lacustrine GDGT-temperature calibration from the Scandinavian Arctic to Antarctic : Renewed potential for the application of GDGT-paleothermometry in lakes
Experimental diatom dissolution and the quantification of microfossil preservation in sediments
Solar variability and the levels of Lake Victoria, East Africa, during the last millenium
A new diatom series with 1–6 year resolution from Lake Victoria, East Africa, shows that lake level minima occurred ca. 820–760, 680–660, 640–620, 370–340, and 220–150 calendar years BP. Inferred…
Catastrophic Drought in the Afro-Asian Monsoon Region During Heinrich Event 1
It is demonstrated that the height of this stadial, about 16,000 to 17,000 years ago (Heinrich event 1), coincided with one of the most extreme and widespread megadroughts of the past 50,000 Years or more in the Afro-Asian monsoon region, with potentially serious consequences for Paleolithic cultures.
Dominant Factors Controlling Variability in the Ionic Composition of West Greenland Lakes
Over 80 lakes were sampled between the ice margin and the coast in West Greenland between 66 and 67°N and analyzed for their pH, alkalinity, conductivity, and major ions. Most of the lakes (67%) are…

Diatom dissolution in surface sediment samples from two regional lake datasets in the Northern Great Plains (NGP; n = 64) and West Greenland (n = 40) is assessed using a morphological approach…
Holocene records of effective precipitation in West Greenland
Holocene changes in effective precipitation (precipitation-evaporation; P-E) were reconstructed for the Søndre Strømfjord region of southwest Greenland using the sediment records of two neighbouring…
Late Holocene precipitation variability in the summer rainfall region of South Africa
Vegetation history in western Uganda during the last 1200 years: a sedimentbased reconstruction from two crater lakes
Pollen, plant macrofossil and charcoal records from two neighbouring crater lakes (Lake Wandakara and Lake Kasenda) in lower montane (altitude-1200m) western Uganda (0.5DN, 30) reveal major changes…
Development and evaluation of a diatom‐conductivity model from lakes in West Greenland
The development of a statistically robust transfer function for diatoms and conductivity will enable the reconstruction of conductivity from the many subsaline lakes around the head of the fjord and, hence, regional estimates of changing palaeoclimatic precipitation.
