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.en-USEstuarine oceanographyOxygen -- British Columbia -- Barkley Sound -- MeasurementOceanic mixing -- British Columbia -- Barkley SoundOther
