A record of secular variation has been obtained from a stalagmite from Vancouver Island, British Columbia, Canada, covering the period 18.5–15.0 ka BP. The ages, obtained by the U–Th method, were not fully constrained because of the low U content of the sample. The record contributes to a regional type curve obtained from the sediments of Bessette Creek (31–19 ka BP), and to which it shows similar features. In particular, a 1600 year long signal of easterly bias and shallow inclinations is… CONTINUE READING
