Environmental Monitoring Progress Report
Q1 Environmental Monitoring Report
As much as our project is about demonstrating the engineering and innovation of the OpenHydro technology we’re using, it’s also one of Canada’s most important research endeavours.
At the time of deployment, we implemented our Environmental Effects Monitoring Program (EEMP) and a suite of marine instruments including the Gemini Tritech Sonar and OceanSonics icListen hydrophones. Together with FORCE, we’re undertaking a level and detail of research hasn’t been done anywhere else in the world, and will advance our understanding about the viability of tidal energy as a source of clean, renewable power. And it will build on the extensive baseline data that already exists.
On April 1, we submitted our first quarterly environmental monitoring progress report to regulators Nova Scotia Environment and Department of Fisheries and Oceans. This interim report for the first three-month data collection period (November 2016 – January 2017), can be found on our website here: Cape Sharp Tidal Q1 EEMP Report . We’d also like to share some of the key highlights:
- With the Gemini Tritech imaging sonar, we’ve positively identified marine life in the sonar’s view plane.
- The four Ocean Sonics icListen hydrophones identified harbour porpoise clicks in November;
- We have preliminary readings from one of our two acoustic recorders that suggest that turbine operational sound is indistinguishable from water flow noise in the Minas Passage below 60 Hz.
We use an adaptive management—or continued learning—approach to monitoring, whereby outcomes are continuously reviewed with regulators and FORCE. This approach allows us to evaluate data and make informed, science-based decisions, modify technology and monitoring methods, assess mitigation measures. And when we temporarily retrieve the turbine, we’ll have the unique opportunity to examine and adjust, where needed, the monitoring equipment.
We know from current public opinion research that most Nova Scotians support demonstration scale instream tidal projects . We are grateful for the community’s ongoing support and the confidence that has been placed in us while we pursue this important research endeavour.
