Quaternary Geology

Quaternary terrestrial, lacustrine and marine sediments are studied to understand glacial dynamics of the Fennoscandian Ice Sheet, past and future climatic, water quality and other  environmental changes. The investigated glacial and high-resolution lake and marine sedimentary records in Finland and worldwide provide information of both natural variations and human impact on the environment.

 

 

Ph.D. Timo Saarinen (UTU)

Professor of Quaternary geology
My research interests: lake and marine sediments, physical and chemical methods, Holocene environmental and climate changes.

Ph.D. Antti E.K. Ojala (UTU)

Professor of Quaternary geology
My research focuses on subglacial landforms called murtoos, late- and postglacial faults and landslides (paleoseismicity), 3D modelling of Quaternary deposits and characterization of clayey sediments for land use and construction purposes.

Ph.D. Saija Saarni (UTU)

University teacher, Postdoctoral researcher
My research focuses on lacustrine and marine sediments covering past and recent environmental changes including climatic variability and plastic pollution.

Ph.D. Maarit Kalliokoski (UTU)

University Postdoctoral researcher
Investigating annually laminated lacustrine sediments as palaeoclimatic and palaeoenvironmental archives using Micro X-ray fluorescence spectrometry (Micro-XRF) and utilizing microscopic volcanic ash layers as geochronological marker layers.

M.Sc. Mira Tammelin (UTU)

Ph.D. student
The main focus of my paleolimnological research is how geology affects the natural nutrient concentrations of boreal lakes and the responses of different lake types to human disturbance.

M.Sc. Sarianna Salminen (UTU)

Ph.D. student
Focusing on varve preservation and spatiotemporal hypoxia oscillation in lakes. What triggers varve preservation and hypoxia oscillation?

M.Sc. Karoliina Kehusmaa (UTU)

Ph.D. student
I'm studying the evolution and effects of mine water induced permanent stratification (meromixis) in two boreal lakes.

Mohib Billah (UTU)

Ph.D. student
I study lacustrine and marine sediments to understand paleoclimate and environmental signatures.
