| Summary: | These data are derived from a dust leaching experiment, an in-lake mesocosm experiment and from sediment cores obtained from lakes in the Kangerlussuaq area of West Greenland. The dust leaching experiment was set up in 2017 and the data show which elements and ions were leached from dust into different types of waters. The in-lake mesocosm experiment applied dust over a two week period in July 2018 resulting in chemical and algal pigment data. Data on chlorophyll and carotenoid pigments are presented from sediment cores sampled from six lakes 2017 and sectioned into 0.5-1cm intervals. ... : The dataset contains results from experiments and sediment core analyses from Kangerlussuaq in West Greenland. A leaching experiment where dust was added to different types of water to compare with a control where no dust was added. The leaching experiment was conducted in Greenland and the chemical composition of the leachates from the treatments was sampled at various time intervals and analysed by ICP-MS at the British Geological Survey laboratories. A second field experiment was conducted in three lakes in Greenland, applying dust to mesocosm enclosures to compare against a control with no dust. Water chemistry was measured at the start and end of the experiment in the field or in the laboratory at Kangerlussuaq International Science Support. Algae from the water and lake bottom was also measured at the University of Nottingham using HPLC pigment analysis. Sediment cores were sampled from six lakes in Greenland in 2017, and sections downcore were analysed for chlorophyll and carotenoid pigments using ... |
