Please indicate your intent to participate by 1 March by emailing Jasmine Saros (
Accommodation deadline: 26 March (see below).


The Bangor International Airport is the closest to UMaine, and is served by American, Delta, and United airlines. Alternatively, you can fly into Boston Logan International and rent a car, or take a 4-hour bus up (Concord Coach Lines, $79 US roundtrip). The bus is very convenient - it picks up right outside of baggage claim at Boston Logan International Airport. Regardless of your arrival terminal, as you exit the building, go to your right and all the way down the sidewalk and you will see a sign for scheduled buses to Maine. Watch for the bus marked Portland - this is the one you want. When you get to Portland, your bus will either go on to Bangor or you will transfer in Portland - the bus driver will let you know. The schedule is online. You can buy a ticket in advance or en route.

Working group aims

The Aquatic Transitions working group will integrate regional records of change in aquatic systems to provide a global synthesis of the sensitivity of sites to critical stages of human impact, detailing the nature of changes that can provide insights for management of these aquatic ecosystems. The two principal objectives are:

1. to document the history of human impact on aquatic systems through the identification of the first point of human impact, and the inception and peak of the impact of the industrialised phase;

2. examine the nature of these transitions to identify the ecosystem dynamics that have resisted human pressures, as well as the changes leading up to the point where the system succumbed, and the degree to which new, stabilising forces have entrenched the system in a new regime.

The WG will collate published palaeolimnnological records and attribute observed changes to critical phases in human activity. It will focus on establishing critical points of impact, which may be time transgressive, with a view to creating a global database to identify timing and causes of change, at regional/continental and global scales.
