Going with the Flow II: Using Drifters to Address Uncertainties in the Spatial Variation of Tidal Flows
October 2017 – June 2018
Drifters are one of the oldest, simplest and most reliable methods for measuring ocean currents. Drifters also provide a simple, low risk platform from which to gather acoustic information along flow streamlines or ‘drift tracks’.

Advanced Coastal Mapping to Support Hydrodynamic Modelling
April 2016 – June 2018
Nova Scotia’s Atlantic coast exhibits a variety of shorelines that may be vulnerable to contamination in the event of an offshore oil spill. In turn, variable currents, changing water levels, shoals, and exposed seaside conditions make effective spill response difficult for tidal inlets.
Measuring the Acoustic Detection Range of Large Whales from an Ocean Glider to Improve an Acoustic Whale Alert System for use by the Offshore Marine Industry in Atlantic Canada
April 2017 – January 2018
Researchers investigated a novel and in-development passive acoustic monitoring (PAM) system for use as a marine mammal detection technique. The work builds on a current research initiative between Dalhousie University and Woods Hole Oceanographic Institute (WHOI).
Turbulence in Grand Passage Nova Scotia: Measures of Intermittency
April – December 2016
Turbulence research is very important to advancing the in-stream tidal energy sector, however turbulence in general is not well understood. Measurement at prospective turbine locations is essential prior to development, given the high degree of spatial variability between sites.
Use of Fish Tracking Data to Model Striped Bass Turbine Encounter Probability in Minas Passage
September 2016
This project used fish tracking datasets and VEMCO detection-range tests to calculate fish-turbine encounter probabilities for striped bass.
Spectral and Structure Function Estimates of Turbulence Dissipation Rates in a High Flow Tidal Channel Using Broadband ADCPs
January 2016
Spectral and structure function methods are implemented to compute the dissipation rate, ε, from broadband, diverging-beam, acoustic Doppler current profiler (ADCP) data collected at four sites in a high-flow tidal channel.
