Description

The Fundy Ocean Research Centre for Energy (FORCE) was established in 2009 as Canada’s leading test centre for tidal energy technology. FORCE is a non-profit grid-connected test facility in the Minas Passage, Bay of Fundy, intended to allow developers, regulators, scientists, and academics to study and demonstrate the performance of in-stream tidal energy turbines and their interactions with the environment. The FORCE site consists of five subsea berths for tidal stream energy conversion devices, subsea power cables that can enable connection of turbines to land-based infrastructure, a subsea data cable, an onshore transformer substation, and a shore-based visitor centre.

Location

FORCE’s test site is in the Minas Passage area of the Bay of Fundy near Black Rock, 10 km west of Parrsboro, Nova Scotia. Minas Passage, only 5 km wide and bordered by basalt cliffs, is the entrance to Minas Basin, the region of the world’s highest tides. FORCE is located in Mi’kma’ki, the ancestral and unceded territory of the Mi’kmaq, covered by the “Treaties of Peace and Friendship” which Mi’kmaq and Wolastoqiyik (Maliseet) People first signed with the British Crown in 1725. Mi’kmaw Peoples have lived on and cared for this land for over 13,500 years.

At mid-tide, the current in Minas Passage is about 4 cubic km per hour. About 160 billion tonnes of water flows through the Bay of Fundy each tidal cycle, equal to four times the estimated flow of all the freshwater rivers in the world combined. With the incoming tide, approximately 14 billion tonnes of sea water flows through Minas Passage into Minas Basin, and central Nova Scotia tilts slightly under the immense load.

The complete Environmental Assessment Registration Document for FORCE (Registered on June 17, 2009 under the Nova Scotia Environment Act), including the Terms and Conditions of Approval (including addenda from 2010 and 2015) can be viewed here. The conditions of its EA approval provide for comprehensive, ongoing, and adaptive environmental management. The EA approval has been amended since it was issued to accommodate changes in technologies and inclusion of more berths to facilitate provincial demonstration goals.

FORCE also has a Crown land lease from the Province of Nova Scotia, which allows it to conduct activities at its demonstration site. Berth holders at the FORCE site are selected by the Nova Scotia Department of Energy and Mines.

Each berth holder is responsible for obtaining all permits and approvals for their individual project. This includes authorizations and/or reviews from Fisheries and Oceans Canada, Transport Canada, and a review of its environmental effects monitoring program by the Nova Scotia Department of Environment.

Project Progress

As Canada’s leading test centre for tidal stream energy technology, FORCE has worked to advance marine research in the Bay of Fundy and beyond since 2009 with the first deployment of an OpenHydro turbine. In 2014, FORCE installed four subsea power cables, which will enable berth holders to connect to the Nova Scotia electrical grid.

Current berth holders include:

Berth A: Eauclaire Tidal Limited Partnership
Berth B: Rio Fundo Operations Canada Limited
Berth C: Sustainable Marine Energy Canada
Berth D: Big Moon Power Canada
Berth E: Haligonia Tidal Energy Limited

FORCE provides common infrastructure and permits, including:

Subsea power cabling: four 34.5kV cables installed, totalling 11km and 64MW capacity
Substation: 30MW transformer and turbine control bays
Grid connection: 10km of 69kV transmission line, connecting FORCE substation to provincial power grid via existing Parrsboro substation
Provincial and federal approvals, including Environmental Assessment and Generator Interconnection Agreements
FORCE-managed on-site work permitting

In addition, FORCE has implemented several key programs:

Fundy Advanced Sensor Technology (FAST) Program, which consists of onshore and offshore assets to support research and development and to advance efforts to monitor and characterize the FORCE site.
Environmental Effects Monitoring Program (EEMP), which has been in place since 2009 to better understand the natural environment of the Minas Passage and the potential effects of turbines as related to fish, seabirds, marine mammals, lobster, marine noise, benthic habitat and other variables. All documents are available online: fundyforce.ca/document-collection
Risk Assessment Program for Tidal Stream Energy (RAP), which is intended to create a detailed, credible assessment tool to gauge the probability that fish will encounter a tidal device by combining biological data and physical oceanographic data.

Key Environmental Issues

Monitoring at the FORCE site is currently focused on lobster, fish, marine mammals, seabirds, and underwater sound and is divided into device-specific (≤ 100 m from a device) and site-level (> 100 m from a device) monitoring. As approved by regulators, individual berth holders are responsible for leading device-specific monitoring in direct vicinity of their devices(s).

ID	Phase	Stressor & Receptor	Design and Methods	Results
6683	Baseline	EMF Fish	Assessment of Potential Ecosystem Effects from Electromagnetic Fields (EMF) Associated with Subsea Power Cables and TISEC Devices in Minas Channel Review of Current Literature and Assessment of Risk from EMFs on organisms in Minas Passage.	Completed Report presents overview and preliminary evaluation of risk to priority species in Minas Passage.
6684	Baseline	Birds	Visual surveys Data on presence and activity of seabirds in the Minas Passage near the tidal energy project site using shore- and vessel-based visual observation surveys (standard observation protocols).	Ongoing Annual report summarizes abundance and patterns since 2009.
6685	Baseline	Invertebrates	Lobster Tagging Program The purpose of this work was to determine the year-round use of Minas Passage as a corridor for movement of lobster. Adult American lobster were captured, tagged with VEMCO acoustic transmitters and released back into the Minas Basin. The lobsters were tracked by bottom-mounted acoustic receiver stations deployed in the Minas Passage. Tracking occurred November – December 2011; April – August 2012; and December 2012-October 2013.	Completed Results suggest lobsters in the Minas Basin move through the Minas Passage towards the Minas Channel in the late fall/early winter and may move back eastward in the spring. Some lobsters may remain in the Minas Basin over the winter and move back through the Minas Passage.
6686	Baseline	Changes in Flow Physical Environment	Currents, waves and tides Vessel-mounted, moored, and turbine-mounted ADCPs. X-band radar, tide gauge. Modelling.	Ongoing Data collection and modelling of currents, turbulence, waves and tides for use by berth holders and scientists.
6687	Baseline	Changes in Flow Physical Environment	Sonar Surveys Multibeam sonar survey of berth sites and cable routes.	Completed Characterization of bathymetry, geology and sediment transport and suspended sediments.
6688	Baseline	Changes in Flow Physical Environment	Environmental Monitoring of Seabed Sediment Stability, Transport and Benthic Habitat Designed to determine conditions on the bottom after the recovery of the turbine in 2010. A side-scan sonar and towed video camera survey was conducted at a Reference Site and at the location of the test deployment site in 2010. Sonograms and side-scan sonar mosaics were interpreted, compared and contrasted with previously collected multi-beam bathymetry and derived backscatter and slope imagery.	Completed The analysis showed no detectable seabed change at the Reference Site since the original data was collected.
6678	Baseline	Marine Mammals	Visual surveys Data on presence and activity of marine mammals in the Minas Passage near the tidal energy project site using shore- and vessel-based visual observation surveys.	Ongoing in conjunction with shore-based seabird visual surveys and beach walks/observation program Annual reports finding that harbour porpoise is the predominant marine mammal observed, with a few seals.
6689	Baseline	Changes in Flow, Habitat Change Physical Environment, Invertebrates	Video and Photograph Analysis of Bottom Substrate and Associated Epibenthic Biota Analysis of video and still photographs taken in 2008-2009 survey to characterize pre-deployment (baseline) benthic habitat within the FORCE test site, including benthic substrate type and macrofaunal biota present.	Completed The survey detected a low number of species present in the FORCE lease area and cable routes, with yellow breadcrumb sponge being the most abundant species.
6679	Baseline	Marine Mammals	Passive Acoustic Monitoring of Cetacean Activity Patterns and Movements Passive acoustic monitoring of harbour porpoise using C-POD & IcListen hydrophones in the Minas Passage to assess how these vary temporally (with respect to time of day, weeks, months and across years), spatially (within and outside the FORCE test area) and with current patterns (tidal cycles and current velocity).	Sufficient pre-deployment baseline data collected; program suspended pending deployment of tidal energy devices. Baseline presence of harbour porpoise around FORCE site and comparison of acoustic devices for monitoring in high flow environments.
6690	Baseline	Changes in Flow Physical Environment	Water Quality Oceanographic measurements included water column temperature, salinity and turbidity profiling; suspended sediments.	Completed Information on water transparency, suspended sediment, and water temperature.
1082411	Baseline	Noise Fish	Hydroacoustic fish surveys 9 hydroacoustic fish surveys were conducted in Minas Passage from May 2016 – August 2017.	Completed The 2019 EEMP Report describes the findings of these surveys and analysis coupled with historical data.
6680	Baseline	Fish	Acoustic Tracking of Fish Movements A multi-year tracking study was conducted to assess the movements of four species of concern that utilize the FORCE test area as a migratory route and for other movements (e.g. foraging) - Atlantic sturgeon, Atlantic salmon, American eel and striped bass. Thirty receiver stations were deployed in the Minas Basin and Passage to detect near year-round animal movements (path, velocity and depth) and behaviour of 386 fish tagged with VEMCO transmitters from 2010-2013.	Completed; ongoing tagging and receiver deployment within Minas Passage as part of the Risk Assessment Program for Tidal Energy. The report summarizes findings on baseline movement of fish species in the Minas Passage and through the test site. Results show that the corridor for fish migration through the Minas Passage is broad and includes the FORCE test area. The results of this study provided evidence of minor use of the passage by out-migrating American eel and Atlantic salmon smolts and more frequent use of the passage by Atlantic sturgeon and striped bass.
6691	Baseline	Noise Physical Environment	Acoustic Monitoring The goals of this project were to: collect pre-deployment (baseline) data on the ambient acoustic environment in the FORCE test site using fixed hydrophone and to assess and refine mooring designs for acoustic monitoring systems in high flow environments.	Completed The results demonstrate that it is possible to collect ambient and in-stream turbine noise signatures in high flow conditions using a fixed autonomous recorder. Mooring designs were tested and improved.
1082412	Baseline	Birds	Radar data Radar scans were assessed to determine if the data could be used to monitor seabird activity at the FORCE site.	Completed Results, including a clear seasonal pattern and effect of wind speed and direction, are described in the 2019 EEMP Report.
6681	Baseline	Fish	Intertidal Weir Surveys Fish catches at two commercial fishing weirs in the Minas Basin were recorded to examine the temporal and environmental (e.g. temp, tide height) patterns in the presence and abundance of resident and migratory fishes. Sampling was conducted during April/May – August 2013 near weekly during daytime low tides and day and night sampling was conducted on 14 consecutive low tides in July at one site.	Completed Data collected provides pre-turbine baseline data on many migratory fishes that move in and out of the Minas Passage.
1082414	Baseline	Habitat Change Invertebrates	Modified catchability survey design. TriNav Fisheries Consultants evaluated the efficacy of using a variety of methods including divers and hydroacoustic tags to track lobster movements.	Completed Fall 2021 Ultimately, TriNav Fisheries Consultants identified the combination of a modified catchability survey design and a mark-recapture study using conventional tags as the best approach for monitoring lobster at the FORCE site.
6682	Baseline	Fish	Hydro-acoustic and Midwater Trawl Surveys Boat surveys from June to August 2010, using a mid-water trawl and an echosounder fish monitoring system. Echo-sounder system sampled acoustic backscatter from throughout the water column to provide information on fish biomass seasonally and spatially and the fishing was used to identify specific species and sizes of fish likely forming the acoustic targets.	Completed Results indicate presence and relative abundance, of a wide range of fish species which use Minas Passage through the summer and fall.
6694	Post-Installation Monitoring	Collision Fish	Active Acoustic Monitoring of Fish Active Acoustic Monitoring (AAM) sonar to be used in conjunction with PAM methods to fully understand the likelihood of nearfield interactions at a turbine.	Implemented by Cape Sharp Tidal Venture; data collection and analysis ongoing N/A
6695	Post-Installation Monitoring	Avoidance, Displacement Marine Mammals	Passive Acoustic Monitoring of Cetacean Activity Patterns and Movements Passive acoustic monitoring of harbour porpoise using C-POD & IcListen hydrophones in the Minas Passage to assess how these vary temporally (with respect to time of day, weeks, months and across years), spatially (within and outside the FORCE test area) and with current patterns (tidal cycles and current velocity).	Ongoing In 2016 and 2017, porpoises were detected on 98.4% of days. Initial results provide no evidence of permanent avoidance in the mid-field of the turbine, but there was a temporary decline in detection rate post turbine installation (41-46%), likely due to vessel activity.
6696	Post-Installation Monitoring	Habitat Change Fish, Invertebrates	Fundy Advanced Sensor Technology (FAST) Program Onshore (MET station, X-band radar) and offshore assets (three subsea platforms)	Ongoing FAST-1 has been deployed and recovered with an acoustic zooplankton and fish profiler (to assess zooplankton and fish density and depth distribution); FAST-2 will soon be deployed with a dynamic mount with a Tritech Gemini imaging sonar; and FAST-3 has undergone multiple deployments with an acoustic zooplankton and fish profiler and an autonomous scientific echosounder.
6697	Post-Installation Monitoring	Habitat Change Human Dimensions, Fisheries	Lobster Catchability Surveys This study was based on measuring lobster catches within test and control areas using commercial lobster traps, in an attempt to assess potential changes in fishing success as result of the deployment and operation of a tidal turbine. Three surveys were conducted, two in the fall of 2009 (before and after turbine deployment) and one in the spring of 2010.	Completed Lobster fishing is essentially the only commercial fishing activity which occurs in the vicinity of the tidal energy demonstration area. The key results are summarized for the 2009 and 2010 surveys; these include independent statistical results review and recommendations for future surveys.
6698	Post-Installation Monitoring	Habitat Change Human Dimensions, Fisheries	Lobster Catchability Surveys A study of similar methods as described above. The first survey took place during October-November 2017 while the turbine was not present, while a second study is planned during turbine operation.	Ongoing During the first survey, 48 traps were deployed and had an average daily catch rate from 4.79-8.99 kg lobster/trap.
6699	Post-Installation Monitoring	Habitat Change Fish, Invertebrates	Near-field Benthic Monitoring To be determined	Planned; FORCE will work with berth holders to conduct near-field benthic monitoring 2018+ N/A
6700	Post-Installation Monitoring	Noise Physical Environment	Acoustic Monitoring The goal of this program is to collect pre- and post-turbine deployment data on the soundscape of the Minas Passage using different drifting hydrophone configurations. Deployments in October 2016 and March 2017, with more planned in 2018.	Ongoing Initial results are that the main source of noise is sediment movement associated with tidal flow and nearby vessel activity. March 2017 drifting hydrophones were able to pick up sounds from the OpenHydro turbine.
6692	Post-Installation Monitoring	Collision Marine Mammals	Active Acoustic Monitoring of Cetaceans Active Acoustic Monitoring (AAM) sonar to be used in conjunction with PAM methods to fully understand the likelihood of nearfield interactions at a turbine.	Implemented by Cape Sharp Tidal Venture; data collection and analysis ongoing N/A
6693	Post-Installation Monitoring	Collision Fish	Hydro-acoustic Surveys Use of downward-looking hydro-acoustics to measure fish density and distribution in water column, leading to creation of an encounter probability model. Three 24-hour surveys pre-deployment (May, August, October 2016) and four 24-hour surveys during operation (November 2016, January, March, May 2017). Additional surveys after removal of Cape Sharp turbine (July, August, November 2017).	Completed Preliminary results show no significant effect of the turbine on the density of fish in the vicinity of the turbine or fish vertical distributions. Future surveys on-hold as FORCE evaluates the effects of entrained air on data quality and ability to quantify effects of turbines.
