Assessing ecosystem-based impacts of port developments on Roberts Bank

Description

Un panache annulaire est mis en place par des employés du MPO sur la pente de Roberts Bank près de l'emplacement prévu pour l'expansion portuaire proposée. Le panache annulaire crée un courant au-dessus du lit océanique afin d'évaluer la stabilité des sédiments. D'autres études ont été réalisées afin d'acquérir des données de base sur le bassin hydrographique du delta du fleuve Fraser.

Roberts Bank supports a dynamic estuarine habitat for economically-important fisheries, as well as internationally important migrating shorebirds. Industrial development has led to local changes and tidal freshwater current carrying sediment from the Fraser River, both of which are critical to the productivity of the region. This industrial development coincided with changes in seagrass beds that serve as nursery habitat for juvenile salmon. An additional superport in the region raises additional concerns about the impact this could have on the watershed of the Fraser River delta. This project will provide baseline data relating to evaluations of habitats covered by the proposed port development and play an important supporting role in relation to possible adaptation efforts proposed by DFO.
