Survey Description

In June 1991, an orientation survey of seaweed was carried out in the intertidal zone of Texada Island, British Columbia.  Common seaweeds were collected at two sites, one near skarn-hosted copper-gold mineralization (Vananda) and the second in a “background” area of basalt (Gillies Bay).  Nine species of seaweed were collected at low tide by plucking the entire plant from the rocks.  Species characteristic of each tidal zone were collected: two species from the upper tidal zone (green seaweed); and two from the low tidal zone (red seaweed).  Care was taken not to include rock fragments.  As seaweed has a high water content, samples weighing up to 1 kg were collected to ensure there would be adequate material for analysis.  A summary of this work can be found in Geological Survey of Canada Current Research, Paper 90-1E.
