Ancient monsoons on the Roof of the World

Recent findings of monsoonal activity in Asia as old as 45 million years raises the fascinating possibility that these Monsoons may have triggered a global shift from the warm ice-free Greenhouse world, to the bi-polar Icehouse conditions the Earth still experiences today. Increased erosion and weathering of the uplifted Tibetan Plateau and Himalayas is currently advocated as the primary trigger for the enigmatic pCO2 drawdown that led to global cooling and rapid growth of the Antarctic ice sheet.

I am Natasha Barbolini, a new postdoctoral researcher in the Department of Ecosystem & Landscape Dynamics. Hosted by Dr Carina Hoorn, I joined the University of Amsterdam working on the MAGIC research project: (Monsoons of Asia caused Greenhouse to Icehouse Cooling). This ERC-funded project is headed by Dr Guillaume Dupont-Nivet at the University of Potsdam, Germany.

Images of modern pollen from Ghana

WDG

The images taken by Adele Julier to help her with pollen identifications during her PhD at The Open University (UK) are now available to download. Please note these images are not of reference material but identifications, made by Adele and myself, of the pollen grains found within her pollen traps. The pollen traps were deployed within vegetation study plots in wet evergreen forest, semi-deciduous moist forest, and the forest-savanna transition zone in Ghana. Further publications on this work and a thesis coming soon…

I discovered what I think is the first colour pollen diagram this week. Published in 1948 and still looks beautiful.

Exploring ancient cesspits in Deventer (Netherlands)

Jippe Kreuning

University of Amsterdam MSc Biological Sciences student Jippe Kreuning investigated the contents of cesspits in the Dutch city of Deventer for his research project. Jippe investigated fossil pollen, seeds and other biological remains to discover what people in the ancient city were eating. In doing so Jippe gained new insights into ancient trade routes.

To find out more about Jippe’s project watch his video courtesy of FOLIA YouTube channel (in Dutch)
