Distribution and autecology of chrysophyte cysts from high Arctic Svalbard lakes: preliminary evidence of recent environmental change
(Peer reviewed; Journal article, 2004)Chrysophycean stomatocyst assemblages were analysed from the sediments of 17 lakes and ponds from Svalbard as one component of a multi-proxy investigation of recent environmental change in the high Arctic. Sediment cores ... -
Effects of within-lake variability of fossil assemblages on quantitative chironomid-inferred temperature reconstruction
(Peer reviewed; Journal article, 2003)We studied the effects of within-lake variation of subfossil chironomid assemblages on chironomid-inferred temperatures in five lakes in southern Norway. In each lake six replicate surface-sediment samples in the deepest ... -
Lake-sediment records of recent environmental change on Svalbard: results of diatom analysis
(Peer reviewed; Journal article, 2004)Surface sediments from 23 lakes on Svalbard were analysed for diatoms. 182 taxa were found but samples generally have a low richness, with the majority of sites dominated by benthic genera such as Fragilaria, Navicula, and ... -
Multi-proxy studies in palaeolimnology
(Peer reviewed; Journal article, 2006)Multi-proxy studies are becoming increasingly common in palaeolimnology. Eight basic requirements and challenges for a multi-proxy study are outlined in this essay – definition of research questions, leadership, site ... -
Recent environmental change and atmospheric contamination on Svalbard as recorded in lake sediments – synthesis and general conclusions
(Peer reviewed; Journal article, 2004)The major patterns of biostratigraphical and geochemical change detected in a multidisciplinary study on recent environmental change and atmospheric contamination on Svalbard are summarised and synthesized. The patterns ... -
Recent environmental change and human impact on Svalbard: the lake-sediment geochemical record
(Peer reviewed; Journal article, 2004)As part of a broader investigation into recent environmental change on Svalbard, the inorganic geochemical record of six lake-sediment cores was analysed. The major temporal trends in sediment elemental composition are ...
