BOSTON — The Massachusetts Department of Environmental Protection (MassDEP) today announced that a new acoustic profiler system to monitor the tidal currents at the western entrance to the Cape Cod Canal has been installed by a consortium of federal, state and private partners, providing mariners with online, near-real-time data of the tidal flows entering and exiting the canal. The current profiler, installed on a pier at the Massachusetts Maritime Academy (MMA) in Buzzards Bay, will improve safety for mariners transiting this area of the canal. 

MassDEP funded the current profiler through the Oil Spill Prevention and Response Trust Fund, partnering with the Northeastern Regional Association of Coastal Ocean Observing Systems (NERACOOS) and the National Oceanic and Atmospheric Administration (NOAA) to support the installation and data testing of the profiler.

“The Oil Spill Trust Fund continues to help coastal communities protect their shorelines through spill prevention and response efforts, and this new tidal current monitor adds another layer of protection for mariners,” said MassDEP Commissioner Martin Suuberg. “We are pleased to work with our project partners to provide navigational aids such as the profiler to support safe transit through Buzzards Bay and the Cape Cod Canal.”

“This current meter will assist all mariners, recreational and commercial, transiting the canal and allow us to better understand the effects of tidal variations, winds and storms on the canal currents,” said Captain Clint Walker, President of the Northeast Marine Pilots Association.

The current profiler will become part of the NERACOOS maritime network and will be part of the NOAA Cape Cod Physical Oceanographic Real Time System (PORTS®), which is comprised of the new current profiler and the previously deployed wave-sensor buoy in Cape Cod Bay. 

“Maritime commerce continues to grow,” said Nicole LeBeouf, Acting Assistant Administrator for NOAA's National Ocean Service. “This partnership will expand the information available to mariners in Cape Cod Bay, improving their ability to operate safely and efficiently.”

“It's always great when we're able to talk with our stakeholders about what they need, and then act to make it happen,” said Tom Shyka, NERACOOS Products and Engagement Manager.

The current profiler has been installed on the pier at MMA, and the system sends an underwater acoustic signal into the canal to determine the speed and direction of the ocean current, providing online data every six minutes to commercial mariners and recreational boaters who often experience dangerous currents of up to six knots at this unique location of the canal. 

“Knowing precise Cape Cod Canal current speed allows safer operations of the Training Ship Kennedy, our Training Vessel Ranger and our fleet of smaller research and training vessels as well as safer operations of vessels operated by the public in the challenging waters of the Cape Cod Canal,” said Rear Admiral Francis X. McDonald, President of the Massachusetts Maritime Academy.

The deployment of the current profiler is part of the ongoing MassDEP and U.S. Coast Guard (USCG) partnership to enhance mariner and environmental protections in Buzzards Bay.

“The U.S. Coast Guard is very pleased in the installment of the current meter at Mass. Maritime. The addition of the real-time current information at the west entrance of the Cape Cod Canal is a welcomed addition to the navigational aids in the area,” said Deputy Sector Commander Brian J. McSorley, USCG Sector Southeastern New England. “The current meter will act as another tool the mariner can use to properly assess the state of the water through the canal and the information can be used for risk-mitigation strategies.”

Woods Hole Group is the approved NOAA service provider, which procured and installed the profiler on behalf of NERACOOS. They will provide ongoing operations and maintenance services for the system, along with the wave buoy in Cape Cod Bay and the nearby Narragansett Bay PORTS.

Ocean current data is now available on the Cape Cod PORTS page and will eventually be delivered on the NERACOOS website, and a MMA data portal. 

Following the April 2003 grounding of the B-120 barge and subsequent oil spill into Buzzards Bay, the Oil Spill Prevention and Response Act established the trust fund to increase the Commonwealth’s ability to prevent and respond to marine oil spills. The Act allows the trust funds to be used for vessel navigational safety improvements, such as current profilers and buoys. In 2016, MassDEP and its partners utilized Oil Spill Trust Fund money to install a high-tech wave-monitoring buoy in Cape Cod Bay to improve the safety of marine transportation in the waters east of Cape Cod Canal.
