Senior Research
Fellow of the Academy of Finland, Docent in Physical Geography
at the University of Helsinki. Research topics include climate
change, freshwater ecosystems, cladocera, lake acidification,
peatland dynamics, carbon cycling, vegetation history, and
aquatic pollution issues, with a major focus on arctic regions
in Europe. Currently co-ordinating numerous national and
international research projects, including EC-funded project
(CHILL-10,000), and national co-ordination of two other EC
projects (MOLAR; EDDI) and two Nordic Council of Ministers
programmes. Author of the Arctic Research Strategy of Finland
for the Finnish Ministry of Trade and Industry. Sub-co-ordinator
of IGBP PAGES PEP III: High-Latitude, High Altitude regions in
Europe. Academic Visitor at Queen's University, Kingston,
Canada, and University College London, UK. Editorial Board
member of Journal of Paleolimnology. More than 40 publications
in international journals.

M.Sc. from University of Oulu, Department of Physical Geography. GIS Manager in the Lapland Regional Environment Centre |
Tasks:
UHEL.LPG (10) provides physical, chemical, biological and
environmental data from more than 300 arctic and sub-arctic
mountain lakes and their catchments (Classification lakes) in
Finnish Lapland, and treats, organises and analyses the data so
that the available information can ultimately be used for lake
classification and regionalisation. GIS methods are used for data
capture, storage, query, overlay, operations and to obtain maps and
frequency distributions of lake conditions and various types of
disturbance for the whole lake population of the area (2000 lakes =
reference Lake District). This part of the work is carried out in
close collaboration with the Lapland Regional Environmental Centre
with an aim to utilise as much as possible the already existing
information on lake chemistry and physics. UHEL.LPG also carries
out an extensive field work survey of 40-50 Validation lakes that
are sampled and analysed for epipelic diatoms, invertebrates,
bacteria, chlorophyll, zooplankton (open water and littoral), and
water chemistry. Short sediment cores are taken from each of the
lakes and be analysed for diatoms, chironomids, cladocerans, SCP,
metals and POPs. Miniature thermistors with an integrated data
logger and infra-red data downloading are installed in 20 of these
lakes along altitudinal and topographic gradients. The catchment
soils of all 40-50 lakes are investigated for depth, bulk density,
CEC, BS and C and N percentages. At the Experimental site
(Saanajärvi) an automatic weather station is installed and
zooplankton, invertebrate and fish sampling is carried out for
analysis of heavy metals and organic pollutants. EMERGE benefits
from close links with other projects based at UHEL.LPG notably the
EC project CHILL-10,000; the nationally funded "Geochemistry of
Podzol Soils and Relations to Lake Water Acidification in Finnish
Lapland"; and the Academy of Finland project " "Northern lakes as
key witnesses for global change: An integrated study combining neo-
and palaeo-ecological approaches".
