Lake Stora Ullfjärden
Radiographs of sediment cores.
Stora Ullfjärden is a bay in the northeastern part of lake Mälaren, situated north of and connected with Lake Lilla Ullfjärden by a narrow and shallow passage.
Radiographic comparison between the upper part of cores 321, 322, and 323 from a depth of 20, 22, and 23 m resprectively in the southern part of Lake Stora Ullfjärden.
The distance between the coring stations 321 and 323 amounted to about 850 m. As shown core-to-core correlations, based on X-ray radiographs, improve the possibilities of calculating spatial variations in sedimentation rates. Date of coring: 1978-03-04.
Coring sites 321, 322, and 323 in Stora Ullfjärden.
