Patterns of apparent oxygen utilization and circulation in Barkley Sound, Vancouver Island B.C.

Abstract

In this study, dissolved oxygen was measured in Barkley Sound and Effingham Inlet with the use of a CTD and Winkler titrations. Oxygen minimum zones or "dead zones" in the world's oceans can be strongly influenced by circulation patterns. Oxygen is a useful tracer of circulation and long and short term processes that can have serious consequences for macrofauna. Areas of old and newer water in Barkley Sound were identified.
