Calcium Nodules as a Proxy for Quaternary Paleoclimate Change on China's Loess Plateau. [PDF]

PLoS ONE, 2015
Different proxies have been used to investigate Quaternary paleoclimate change. Here, we used weathering of calcium nodules in paleosols on China's Loess Plateau as a proxy for Quaternary paleoclimate changes to provide an alternative indicator of these ...

Comparing non‐staining methods with Mutvei's solution to visualize growth increments in short‐lived intertidal marine gastropod shells

Limnology and Oceanography: Methods, EarlyView.
Abstract Mutvei's solution is a widely utilized standard staining method for revealing growth increments in biogenic carbonates; however, it is a slightly toxic, destructive approach with varying success across species groups. Therefore, there has been growing interest in finding non‐toxic, less destructive, and straightforward alternative techniques ...

Studying Africa's hydroclimate history over the last 2000 years [PDF]

, 2016
Water-resource availability is one of the most important environmental factors on which Africa’s agricultural societies are reliant. However, our knowledge of the natural background variability of rainfall and drought over Africa is currently still ...

Simulations of Titan’s paleoclimate [PDF]

Icarus, 2014
We investigate the effects of varying Saturn's orbit on the atmospheric circulation and surface methane distribution of Titan. Using a new general circulation model of Titan's atmosphere, we simulate its climate under four characteristic configurations of orbital parameters that correspond to snapshots over the past 42 kyr, capturing the amplitude ...

Digitizing collections to unlock the full potential of palynology: A case study with the Smithsonian palynology collection

PLANTS, PEOPLE, PLANET, EarlyView.
Large palynological collections have been built over decades and contain vital information. However, they are often difficult to access and use effectively. What is the point of having such collections if they are not fully utilizable? To solve this problem, we digitized the Smithsonian palynological collection using both light and confocal microscopy.

La2010: A new orbital solution for the long term motion of the Earth

, 2011
We present here a new solution for the astronomical computation of the orbital motion of the Earth spanning from 0 to -250 Myr. The main improvement with respect to the previous numerical solution La2004 (Laskar et al.

Can the last glacial maximum constrain climate sensitivity? [PDF]

, 2012
We investigate the relationship between the Last Glacial Maximum (LGM) and climate sensitivity across the PMIP2 multi-model ensemble of GCMs, and find a correlation between tropical temperature and climate sensitivity which is statistically significant ...

PaleoClim, high spatial resolution paleoclimate surfaces for global land areas [PDF]

Scientific Data, 2018
AbstractHigh-resolution, easily accessible paleoclimate data are essential for environmental, evolutionary, and ecological studies. The availability of bioclimatic layers derived from climatic simulations representing conditions of the Late Pleistocene and Holocene has revolutionized the study of species responses to Late Quaternary climate change. Yet,
