Q2 ENVIRONMENTAL MONITORING REPORT

Posted on: July 10, 2017

On July 1, we submitted our second quarterly Environmental Effects Monitoring Program (EEMP)   report to Nova Scotia Environment. This report provides an update for the second quarter of the monitoring program (February – April 2017), and can be found on our website here:  Cape Sharp Tidal Q2 EEMP Report. We’d also like to share some of the key highlights:

  • The turbine continued to perform well during the Q2 commissioning period.
  • In the beginning of April, operations were initiated to retrieve the turbine to make minor repairs and upgrades to some Turbine Control Centre (TCC) components. This will also provide us opportunity to examine and adjust, where needed, the monitoring instrumentation.
  • Testing and data collection from monitoring sensors continued throughout Q2.
  • Two hydrophones and the Gemini sonar continued to operate until the sub-sea cable was disconnected in preparation for turbine retrieval. As in Q1 there was no communication from the video camera and one hydrophone. A second hydrophone was intermittent.
  • This second quarter has been focussed on identifying areas where the data collection process can be refined and to develop protocols to efficiently manage, store and share that data. This has included software improvements and successful adjustments to monitoring instrument frequencies for improved data collection. Additional work has also been completed on preliminary analysis and data interpretation.
  • A contingency monitoring program was developed to be implemented during times of disconnection but when the turbine remains deployed.

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. Now that we’ve temporarily retrieved the turbine, we have the 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 appreciate the community’s ongoing support and the confidence that has been placed in us while we continue to pursue this important research endeavour.
