OCEANOGRAPHIC CONNECTIONS AMONG NATIONAL MARINE CONSERVATION AREAS IN NORTHERN BRITISH COLUMBIA

An important consideration in designing a network of marine protected areas is the oceanographic connections among coastal regions. Connectivity related to source/sink processes is fundamental to network design because many marine invertebrates and fishes have pelagic egg or larval stages that can be dispersed by oceanic currents. In this study, an oceanographic model was developed for seas around the proposed Gwaii Haanas National Marine Conservation Area (NMCA). The model combines information on water density properties, tides, and 40 years of coastal wind data. Simulated particle transport experiments, using generic invertebrate and fish larval life history traits, were conducted to explore the connectivity of the Gwaii Haanas NMCA in spring. Two major questions were asked: What physical oceanographic and wind conditions result in connections to other regions, and how important are life history strategies?
