Project: Sedimentological and Inchnological Characterization of Mixed Sand and Gravel Beaches
The goal of this study is to quantitatively determine relationships between sedimentology, ichnology, and hydraulic energy for beaches developed along a relatively straight coastline. The southwest coast of Vancouver Island (along the Juan de Fuca strait) is relatively protected from open ocean swells, with well-developed sand- and gravel-dominated beaches. Given the similarity of hydraulic energy along the coastline, it is possible to assess changes in depositional character of the beaches deposited along it. French beach, China beach, and Sombrio beach will be studied to compare their ichnological, and sedimentological character. Hydraulic energy data (wave height, tidal currents, alongshore transport) will be collected with Doppler current meters. Sediment sources and alongshore drift directions will also be established for the study area. The subtidal components of the beaches will also be studied, to be sampled using SCUBA techniques. Theoretically, relationships determined from this study can be used as a means of predicting along-strike variability of beach sediments preserved in the rock record.
