Sediment accumulation rates in European lakes since AD 1850: trends, reference conditions and exceedence

Climate Change Impacts on Sediment Quality of Subalpine Reservoirs: Implications on Management

“…Increases of sedimentation rate have been observed in many European lakes over the last 100 years, in particular during 1950-1975 period and post-1975. This indicates a general acceleration in sedimentation rate during the second half of the twentieth century [90]. Whereas increases in sedimentation rate in many lowland areas may be due to changes in agricultural practices and other land-use changes in the lake catchments, the same cannot be said of upland and mountain lakes where land-use has remained largely unchanged.…”

Topical advances and recent studies in paleolimnological research

“…Battarbee et al (2011b) examined sediment cores from 121 low-alkalinity lakes in the UK and constructed a pre-acidification typology of lakes that showed 3 main clusters of water quality as indicated by diatom taxa. Rose et al (2011) examined sediment accumulation rates of dated sediment cores from 207 European lakes to determine how accumulation rates changed in 25-year intervals. Study lakes were grouped with respect to alkalinity, altitude, depth, and area, and about 71% of the lakes demonstrated increased deposition rates over the last 100 years.…”

Ecological effects of multiple stressors on a deep lake (Lago Maggiore, Italy) integrating neo and palaeolimnological approaches

“…Human impacts on Italian aquatic ecosystems have intensified considerably since ~1945 (Guilizzoni et al 1982;Guilizzoni et al 2011;Rose et al 2011). Urbanization and industrial activities have increased, resulting in greater export of chemical pollutants, organic matter and nutrients to rivers and ultimately to lakes (Pagnotta and Passino 1992).…”
