Vessel Strikes

Vessel strikes pose a significant threat to the endangered North Atlantic Right Whale, as well as putting smaller vessels and passengers at risk.

◆ Cause fatalities and injuries to whales

◆ Damage boats and risks passenger safety

◆ Whale locations shift in real time

◆ Disrupt core habitats within busy East Coast waters

NOAA Speed Rule

Current NOAA speed rules reduce the severity and frequency of collisions by requiring a 10 knot speed limit for vessels over 65 feet in NARW habitats.

◆ SEASONAL – Mandatory speed restrictions in migration and congregation areas

◆ DYNAMIC – Voluntary speed reduction in areas of NARW congregation

AIS

Automatic Identification Systems (AIS) can remotely and automatically warn vessels to slow down in protected areas or when a whale is detected in their vicinity.

Stellwagen Test

During March and April of 2024 a pilot project was conducted in Cape Cod Bay to send targeted messages to vessels out of compliance with the speed rules.

◆ 60 day test during Spring 2024 in Cape Cod Bay

◆ 2 AIS transceivers monitor traffic and message vessels exceeding 10 knots

◆ 10nm Majority of vessels slowed to compliance

◆ Duration: 60 days (March–April 2024)

◆ Coverage: ~10 nautical mile monitored area

◆ Infrastructure: 2 AIS transmit/receive stations

◆ Monitoring: Continuous vessel speed and position

Objective

◆ Improve compliance with NOAA speed restrictions

◆ Increase real-time awareness in active whale zones

◆ Majority of targeted vessels reduced speed

◆ Improved awareness of active protection zones

◆ Real-time messaging proved effective in-field

AIS enhances maritime safety by providing real-time data on vessel identity, position, speed, and navigational status. This information is automatically shared with shore stations, other vessels, and aircraft.

AIS Safety-Related Messages: Transmit urgent safety and navigational information directly to vessels and authorities.

AIS Virtual Markers: Electronically indicate hazards or important locations on navigational systems.

AIS Geographic Notices: Provide real-time updates on specific navigational rules or restrictions for defined areas.

The Automatic Identification System (AIS) is an internationally recognized maritime safety technology used by vessels worldwide. StationKeeper stations receive AIS transmissions and contribute to a growing network that helps improve awareness of vessel activity along our coasts. This information supports conservation initiatives, educational programs, research efforts, and maritime safety.

Network

A growing network of coastal monitoring stations working together to improve awareness of vessel activity in and around sensitive marine environments.

Applications

StationKeeper supports conservation, research, maritime safety, and environmental stewardship by providing greater visibility into vessel activity and long-term traffic patterns.
