Abstract

Here, the AA. use magnetic "fingerprinting" to characterize soils, and examine their affinity with and contribution to suspended sediments transported within 2 subcatchments feeding Bassenthwaite Lake, northwest England. Combining the spatial and vertical (down-profile) soil magnetic data, a subset of soil profiles was selected for detailed, laboratory-based magnetic remanence analyses. Magnetic analyses were performed on the 31-63μm fraction, for particle size-specific comparison both with the suspended sediments and lake sediments. Examination of the cluster affinity of the soils, suspended sediments and lake sediments indicates that topsoils of the upper Newlands Valley and subsoils around Keskadale Beck are a major source of the Newlands Beck suspended load, and the recent (post-nineteenth century) sediments in the deep lake basin
