Seasonal current simulations for the western continental margin of Vancouver Island

Spatial aggregations of seabirds and their prey on the continental shelf off SW Vancouver Island

We investigated the spatial scales at which seabirds aggregate and associate with prey over the continental shelf off southwest Vancouver Island, British Columbia. Bird densities and hydroacoustic measures of prey abundance were recorded in all seasons from 1993 to 1995 from a vessel moving along fixed strip transects (mean distance 93 km; minimum spatial units 250 m). We used the neighbour K a...

The Suquash Coalfield, Vancouver Island

This report is part of an ongoing project, begun in IYX7, drain the district. Most of the coalfield is covered by till which limits exposures to the showline, rivers and roadcuts. Climate is fairly mild and wet, and snowfall is common to update knwledge of the coal basins of Vancouver Island. Limited information exists pertaining to coelmeasures of the Squash crudfield or snh-basin (the terms c...

Great earthquakes along the Western United States continental margin: implications for hazards, stratigraphy and turbidite lithology

We summarize the importance of great earthquakes (Mw & 8) for hazards, stratigraphy of basin floors, and turbidite lithology along the active tectonic continental margins of the Cascadia subduction zone and the northern San Andreas Transform Fault by utilizing studies of swath bathymetry visual core descriptions, grain size analysis, Xray radiographs and physical properties. Recurrence times of...

Galena Lead Isotope Model for Vancouver Island*

This paper demonstrates how a galena lead isotope model can be used to make decisions about the age and origin of ore deposits on Vancouver Island. To build this model we draw on the galena data of Table 1-9-1 (compare Andrew and Godwin, in press a, b, c and Godwin et al., 1988). Galena lead isotope data from Vancouver Island do not show a systematic evolution with time. Therefore they cannot b...
