Background and aims In forestry-drained peatlands, drying leads to changes in C cycling which could affect peat δ13C. Furthermore, the δ13C profile of the entire peat column may reveal effects of earlier climatic periods. Methods We measured peat

The total area of boreal peatlands is about 3.5 million km2 and they are estimated to contain 15–30% of the global soil carbon (C) storage. In Finland, about 60 000 km2, or 60% of the original peatland area, has been drained, mainly for forestry im

We studied organic matter accumulation dynamics in peatland surface soil, using the root collar depth of tree-ring aged Scots pine seedlings for dating the base level of quantitative soil samples. The data consisted of 222 samples collected from 47 f

The goal of this study was a harmonization of diatom identification and counting among diatomists from the Scandinavian and Baltic countries to improve the comparison of diatom studies in this geographical area. An analysis of the results of 25 diato

Lakes in Europe have a bipolar distribution by latitude with higher lake densities in the north (58–65° N) and south (38–48° N). By area, 95% of the large lakes (>100 km2) are located at altitudes lower than 100 m above sea level (ASL) and only

A man-induced extensive silty layer in the sediment of Lake Lovojarvi, dating back to the year 1960, contained 18 laminations due to rhythmical variations in the size classes of the mineral particles. A good agreement was found between the thicknesse
