The Swedish lakes with the selected coring stations

The development of lake basins is reflected in the composition and sequence of the sediments which are deposited on their floors. The adverse environmental effects of man´s activities (e.g. soil erosion and water pollution) are also recorded in the sediment deposits. However, the environmental changes which are recorded within the depositional sequence are often hard to interpret. This is partly due to the lack of knowledge about the processes and rates of sediment production, sediment redistribution, and sediment accumulation. There is, therefore, a great need for improved methods of analysis of the uppermost portion of the sedimentary sequence in particular, and for the calculation of past and present rates of sedimentation.

The information about primary and secondary sedimentary structures that is provided by X-ray radiographs simplifies the determination of sedimentary properties, and facilitates the interpretation of changes in the depositional environment. X-ray radiographic techniques have been used for the determination of sedimentary properties in several lakes in Sweden. Some of these lakes are named in the frame to the left and on the map below. The Swedish lakes with radiographs of selected sediment cores, named to the left, are in the main arranged from south to north.
