Cultural and non-cultural variation in the artifact and fauna samples from the St. Mungo Cannery site, B.C., DgRr 2Boehm, Sheila Gay Calvert 27 June 2016 (has links)
The records or both the faunal remains and artifacts recover d from the St.Mungo Cannery site in the Fraser Delta, British Columbia during 1968-1969 are analysed quantitatively for evidence of processual cultural change. Descriptions of the site and site habitat are given, and methods used to recover, describe, and analyse the two records are detailed. The patterns of variation through time are given in tables of the relative frequencies of types found in excavation units Cl and C2. Multidimensional scalogram analysis is used to delineate and visually present the separation of components. An attempt is made to distinguish cultural variation in the two records from non-cultural variation produced by sampling procedures, and to control for the latter. The relationship between sample size and the number of artifacts and faunal types found is statistically demonstrated as a major sampling error . Some comparisons are made between the patterns of variation observed in faunal and artifact types theoretically related as evidence of particular activities. The information contained in the faunal record is found to be additional as well as parallel to that contained in the artifact record. / Graduate

Development of a salt marsh on the Fraser delta at Boundary Bay, British Columbia, CanadaShepperd, Jane Elizabeth January 1981 (has links)
The development of a late Holocene salt marsh was studied on the inactive part of the Fraser Delta at Boundary Bay, southwestern British Columbia. Present-day vegetation zones near 64th Street, South Delta, in the western part of the Bay, were distinguished in the salt marsh and were related to zones found in cores obtained in a transect across the marsh. A sequence of development, related to elevation, was determined. Salicornia and Triglochin are pioneer colonizers of the tidal flats and are sometimes associated with areas elevated by algal mats. As the area was elevated, sediments were trapped by vegetation and stabilized by rhizomes, and other halophytes grew, including Cuscuta, Sperqularia, Atriplex, Distichlis, Grindelia, and Plantago. A zone characterized by abundant Atriplex represents positions of former strandlines. As further emergence occurred, mesophytes became dominant and, in the landward, most emergent zone, a diverse flora of Maius, Sjdalcea, Aster, AchiIlea, Solidaqo, Elymus, Angelica, Juncus, and grasses developed. A radiocarbon date on Salicornia-rich organic silts at a depth of 35 to 40 cm in core 5 suggests that salt marsh development commenced 320 ± 70 years B.P. (GSC-3186).
A former salt marsh peat is now partially buried and being actively eroded where exposed near 112th Street, South Delta, in eastern Boundary Bay. A paleoenvironmental reconstruction suggests the peat started developing in freshwater, with ferns, sedges, Typha, and Nuphar. Later, it was successively inundated by marine water and a salt marsh developed, as seen by an increase in the abundance of chenopod pollen. Subsequent emergence of the salt marsh was accompanied by the development of an increasingly diverse vegetation. / Science, Faculty of / Earth, Ocean and Atmospheric Sciences, Department of / Graduate
