Post-conference Excursion August 16, 2012

Rokua Esker Aquifer and Groundwater-dependent Ecosystems


This excursion will pass through the Oulu river basin, ending at the Rokua esker, about 70 km east of Oulu. The excursion will conclude with a traditional Finnish summer evening event, with sauna and refreshments.

Rokua esker aquifer is one of the largest and most studied aquifers in Finland. This esker was formed during the last deglaciation and has the status of a Finnish national park. It has a unique landscape consisting of picturesque kettle lakes and sand dunes. It is also the first Geopark site in Finland. The esker has several clearwater lakes that are dependent on groundwater. During the excursion, hydrogeology, groundwater monitoring and recent research on surface-groundwater interactions in eskers will be introduced. In addition, issues such as the impacts of land use (i.e. forest drainage) and climate change on groundwater are being studied at Rokua and will be introduced during the excursion.
