MARC recordEstimating ecesis for tree-ring dating of moraines: a comparative study from the Canadian Cordillera / Daniel P. McCarthy, Brian H. Luckman.
| Title: | Estimating ecesis for tree-ring dating of moraines: a comparative study from the Canadian Cordillera / Daniel P. McCarthy, Brian H. Luckman. |
| Author(s): | McCarthy, Daniel P. Luckman, Brian H. |
| Date: | 1993. |
| In: | Arctic and Alpine Research. (1993.), Vol. 25(1) (1993) |
| Abstract: | Studies from glacier forefields in Cordillera report that conifers ecize in 5 to 60 a. Comparative studies of four methods of ecesis determination in two glacier forefields in British Columbia indicate that traditional approach of sampling trees on small dated surfaces may yield ecesis estimates that are too large. Results from sampling on transects running orthogonal to moraines, interpolating surface age between fixed points based on historical photographs, provided improved estimates of ecesis by enlarging area and range of environments sampled. Although traditional and transect techniques may give comparable results in well-vegetated forefields, transect technique is recommended as better estimate of ecesis in sparsely vegetated terrain. |
