Presentation Abstract
The most dramatic (albeit largelyy unseen) aspect of the Strait of Georgia's circulation is its deep-water renewal. Waters below about 200m are replaced only during summer, but within the summer season only in short pulses a few days long each month. These deep water renewal events are associated with intrusions of dense Pacific Ocean waters into the Strait of Georgia through the narrow Juan de Fuca Strait during summer coastal upwelling periods. These events cause fluctuations in oceanographic properties of the Strait of Georgia, such as salinity, dissolved oxygen, temperature and nutrients, and result in large increases in turbidity near the bottom of the southern Strait as sediment is resuspended and transported northward. We analyze and interpret several datasets to describe variability of the deep water renewal process and its effects on water properties.

Oceanographic properties and effects of Deep Renewals in the Strait of Georgia
The most dramatic (albeit largelyy unseen) aspect of the Strait of Georgia's circulation is its deep-water renewal. Waters below about 200m are replaced only during summer, but within the summer season only in short pulses a few days long each month. These deep water renewal events are associated with intrusions of dense Pacific Ocean waters into the Strait of Georgia through the narrow Juan de Fuca Strait during summer coastal upwelling periods. These events cause fluctuations in oceanographic properties of the Strait of Georgia, such as salinity, dissolved oxygen, temperature and nutrients, and result in large increases in turbidity near the bottom of the southern Strait as sediment is resuspended and transported northward. We analyze and interpret several datasets to describe variability of the deep water renewal process and its effects on water properties.
