Extending the multiproxy toolkit in Jamaica

Palaeoenvironmental projects in Jamaica – extending the multiproxy record

As some of you may have read in our recent blog post, Professor John Smol and Chris Grooms from the Paleoecological Environmental Assessment and Research Lab, Queen’s University, Canada visited the University of the West Indies last month.

Lecture by Professor John Smol: “The past matters: Using lake sediments to study the environmental effects of multiple stressors”

There was an excellent turnout from students of the Department of Geography and Geology who found the lecture very insightful. The lecture was followed by numerous questions from the students which led to interesting discussions on the various paleolimnological techniques that Professor Smol uses and the case studies he presented from his work in the Arctic and Canada. We thank Professor Smol for giving a superb lecture!

Manatee Bay, Jamaica

Manatee Bay, Jamaica

As part of their visit we took John and Chris to Manatee Bay, St. Catherine heading out from Old Harbour Fishing Beach with Mr Charles Moodie. We have been working at Manatee Bay for some years on an extensive sediment core record (15 cores) to reconstruct environmental conditions over the last millennium and investigating marine washover events. To do this we are using various proxy data including ostracods, benthic foraminifera, and micro-XRF sediment geochemistry.

Extending the multiproxy toolkit in Jamaica

As part of our research programme we are working on a number sediment cores from lakes and coastal lagoons around Jamaica. We will be working with the PEARL lab to increase the number of proxies that we use in order to improve our understanding of environmental and climatic change over the last millennium.

St. Georges Lake

St. George’s Lake, Jamaica

Chris Grooms at St. George's Lake, JamaicaMike joined Chris Grooms and Stefan Stewart (Founder and Head of the Jamaica Cave Association) on a field day around various lakes and ponds across Jamaica to carry out sampling of surface sediments and lake water. The PEARL lab have designed a special coring technique for recovering unconsolidated sediments at the surface-water interface. John and Chris will be looking for the presence of diatoms amongst other paleolimnological indicators, and we are going to have a look at the pollen, ostracods and any other critters we may come across!

We are looking forward to working with John, Chris and colleagues on new and existing palaeoenvironmental projects in Jamaica!
