An undergraduate eye-view of an Andean lake-coring expedition

Part 1: Huayabamba
by Molly Kingston (a BSc Biological Sciences student at Florida Institute of Technology, taking part in an expedition lead by Prof. Mark Bush)

When I first heard about this class in Peru, I had no idea that I was going to experience so much in such a short period. Our goal was to visit two lakes in Peru and raise sediment cores for paleoecology. The first lake that we went to was Laguna Huayabamba, which sits at about 3250 m elevation in the La Libertad region of the Peruvian Andes.

However, getting to this lake was no easy task. Before the hike even started, we had to obtain the necessary permits and permission from the local people. After several days of visiting different town officials and waiting for approval, we could set out on our adventure.

Ancient monsoons on the Roof of the World

Natasha Barbolini

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.
