LOBO-0010 Northwest Arm, Halifax, Canada


The Northwest Arm defines the southwest edge of peninsular Halifax, and is heavily used for recreational purposes. It is has a mean peak tidal velocity of 0.3 m/s that daily flushes anthropogenic effluents and turbid discharges into the greater harbor. LOBO is an ideal system for monitoring the water quality of this key estuarine resource.

This LOBO node is situated midway from the head to the mouth of the arm in order to measure trending relationships between cyclical vertical current flux and the nitrification of benthic and suspended microrganisms. The resulting data show how fluctuations in salinity and dissolved oxygen interact with biological processes over seasonal variations in temperature and available light.
