PCRG COMPLETE AGAIN

I am glad to say that after almost two months out of the office running around with 8 bags of equipment, Frazer and I have finished our tour of the Americas. As the work has been so diverse, we would like to split our comments and impressions into two different posts, we hope you enjoy them!

Two studentships avaliable

Two NERC algorithm funded PhD studentships are currently available with the PCRG. The projects are focused on understanding past environmental change in west tropical Africa and Amazonian-Andean Ecuador. Both projects will involve field work and build on on-going research within the lab.

Closing date 31/01/2013

Fieldwork in 2012 near Papallacta (Ecuador).

One project will work on samples collected during fieldwork in 2012 near Papallacta (Ecuador).

Sediment sampling on the Andean flank, Ecuador

One of the key goals of the fieldtrip to Ecuador (August-September) was to sample organic and volcanic (tephra) layers from sedimentary exposures with the aim of obtaining new information about past envrionmental change in the region. Our Ecuadorian collaborator, Dr Patricia Mothes (Instituto Geofisico), had identified four of sites she thought might be useful too us: El Fatima Dique, Mera “2” Dique, El Rosol and Vinillos. 

Fatima section

At the Fatima site, near Puyo, a thin organic bed was sampled sandwiched between volcanic ash deposits. Wood macrofossils from this deposit have been dated to the last glacial period.

Mera fieldwork continued…

The first half of our field work expedition to Ecuador has now been completed. We had a very successful visit to Mera collecting samples from three new sections and recovered short cores from four lakes.

The sediment sections have yielded many wood macrofossils and samples for pollen analysis. It is anticipated that these will shed light on the nature of tropical vegetation during the last glacial period and before. Some of these samples will be analyzed by Hayley as part of her PhD research.

Mera "Forest bed"

The sedimentary section found near Mera contained layers of crushed forest beneath volcanic ash. These “forest beds” provide a snapshot of vegetation in the landscape at the time of eruption. Part of plants growing on the landscape thousands of years ago are clearly preserved in the sediment.

PCRG August

I am writing this August post from the Hotel Rincon Escandinavo (Quito, Ecuador) most of this month has been pretty hectic as we have been preparing for this field work trip and trying to get as many things out the way before hand.

We seem to have been quite involved in conference activity: Lottie presented “500,000 years of vegetation change from West tropical Africa” at the International Paleolimnology Association Symposium in Glasgow, Hayley had an abstract on “Pollen counting for diverse tropical ecosystems”  accepted for the Linnean Society Palynology Group meeting (1 November) and group members also submitted abstracts for consideration to be presented at the American Geophysical Union Congress and British Ecological Society meeting (both in December); fingers crossed these will be accepted as well.

Regarding the field work. Preparation seems to have gone well and we have arrived in Quito with all out bags, despite a short (1 hour) connection in Madrid. Tomorrow we will meet up with Dr Patricia Mothes (Instituto Geofisico) and set out our detailed plans. As I have now been up for more than 24 hours I should probably get some sleep… Plan is to blog more about the trip as it happens.
