Abstract. Lake Ohrid is likely of Pliocene age and thus
commonly referred to as the oldest existing lake in Europe.
In this study spatial variability of recent sediment composition
is assessed using >50 basin wide distributed surface
sediment samples. Analysis of biogeochemical bulk parameters,
selected metals, pigment concentrations as well as grain
size distributions revealed a significant spatial heterogeneity
in surface sediment composition. It implies that sedimentation
in Lake Ohrid is controlled by an interaction of multiple
natural and anthropogenic factors and processes. Major factors
controlling surface sediment composition are related to
differences in geological catchment characteristics, anthropogenic
land use, and a counterclockwise rotating surface
water current. In some instances processes controlling sediment
composition also seem to impact distribution patterns
of biodiversity, which suggests a common interaction of processes
responsible for both patterns.
