We briefly discuss how the thermoluminescence (TL) profile of a young marine sediment provides phenomenological information on the changes in the environmental conditions in the past 18 centuries. The main periodicities present in the TL profile are studied and the similarities between the TL variations and the fluctuations in the contemporary tree-ring A 14 C signal are considered. An interesting result is the presence, in the TL data, of a well-defined 11-year cycle which is stable and ‘in phase’ for the entire period analysed. We also discuss how four dominant periodicities present in the TL data may be rewritten as the sum of an 11.4-year and of an 82.6- year cycle (reminiscent respectively of the Schwabe and of the Gleissberg cycles of solar activity), which are both amplitude modulated by a 206-year wave. This last periodicity has already been shown to play a dominant role in the A 14 C record. These results suggest that the TL profiles of recent marine sediments may be successfully used as a new line of evidence for solar variability in the past centuries.

Pollen analysis of a 7.65 m sediment core from Eaglenest Lake (57°46′N, 112°06′W) provides evidence of the postglacial development of vegetation in the mixedwood section of the Boreal Forest. From the time of deglaciation (approximately 12 000 – 11 500 years BP) to 11 000 BP the area was colonized by mainly nonarboreal flora dominated by Artemisia and Gramineae. Populus, the only tree taxon present, grew in sheltered areas, while Salix and Cyperaceae were common on poorly drained sites. Open parkland prevailed under a dry, windy climate. Summer temperatures were rising rapidly from glacial minima in response to increased solar insolation. By 11 000 BP Picea (initially P. glauca) and Betula (mainly tree Betula) migrated to the area. Forest prevailed, but the canopy was likely more open than at present. By 9000 BP peak warm and dry conditions had passed, although conditions warmer and drier than at present persisted. Alnus migrated to the area 8450 BP. Pinus reached the Birch Mountains about 7500 BP. No major changes in vegetation have occurred since that time, suggesting that modern climatic conditions were established by 7500 BP.
