Abstract
In the Canadian Arctic, several proxy-climate records are being used to quantify Holocene climate variability, including microfossils (pollen grains, chironomid head capsules, diatom valves) and sediment parameters such as biogenic and organic content. Modern datasets have been developed for these parameters and used in modern calibration exercises. However, the size and geographic extent of the modern-calibration set, the availability and preservation of fossil material as well as difficulties in understanding the relationship between fossilised organisms and their environments can all significantly affect the resulting environmental reconstructions. In some cases, surprising results have been generated when seemingly robust calibration models have been applied to Arctic lacustrine sediment cores. The status of modern datasets for pollen, diatoms, chironomids and BSi will be discussed and applications in several cores presented. The various proxies can be compared to serve as checks on each other.
