Whales and acoustic disturbance • Southern resident killer whales use sound to find food, communicate and navigate • Ship noise can disrupt their ability to communicate, socialize, rest and their ability to hear returning echolocation clicks when feeding Whale echolocation Sound clip: Northern resident killer whale masking from passing commercial vessel.

Commercial shipping activities and whales An international issue • International shipping lanes overlap protected critical habitat for endangered southern resident killer whales and other at- risk species • Underwater noise can affect whales’ ability to feed and communicate • Predicted shipping activity and human population growth in both Canada and USA • Port authority mandate under the Canada Marine Act Vancouver Fraser Port Authority | 8

What is the ECHO Program? Vancouver Fraser Port Authority | 9

Enhancing Cetacean Habitat and Observation (ECHO) Program overview What? A collaboration with marine transportation industries, conservation groups, scientists, Indigenous individuals and Canadian and US governments. When? Convened Nov 2014 Why? To better understand and reduce the cumulative effects of commercial shipping activities on at-risk whales throughout the southern coast of British Columbia. Key actions: • Collaborative international and regional relationships. • Research projects, with an emphasis on underwater noise. Photo: Joan Lopez • Trial and implement threat reduction measures Vancouver Fraser Port Authority | 10

Species At Risk Act Conservation Agreement to support recovery of southern resident killer whales • First of its kind in Canada • Formalizes role of ECHO Program over five- year term • Focuses on existing and new voluntary efforts to reduce acoustic and physical disturbance from large commercial ships operating in Southern Resident killer whale critical habitat Vancouver Fraser Port Authority | 11

Key acoustic research questions • What are current ambient noise levels? • What do different ships sound like? • Where do different types of ships contribute to noise? • What options exist to reduce underwater noise from ships? Photo: Joan Lopez Vancouver Fraser Port Authority | 13

What are current ambient noise levels? Underwater noise monitoring in the region • Three locations with two years of data • Undergoing analysis for drivers of ambient noise and trends Burrard Inlet • Environmental conditions (current, wind, rain, marine animals) • Anthropogenic factors (small and large boats and Strait of Georgia ships) • Fourth location 2019 – Burrard Inlet Boundary Pass Haro Strait Vancouver Fraser Port Authority | 14

What do different ships sound like? U nderwater listening stations Locations: • Strait of Georgia • Haro Strait • Boundary Pass Listening for: • Level of noise from ships (10,000+ ship transits) • Marine mammal detections • Ambient noise Photo: VFPA Vancouver Fraser Port Authority | 15

What do different ships sound like? Strait of Georgia underwater listening station Average Five loudest ship types radiated noise level* Container ship >200m 189.7 dB Bulkers >200m 186.6 dB Ferries 186.5 dB Tankers 185.9 dB Bulker <200m 185.9 dB Source: Strait of Georgia underwater listening station, 2015 – 2018 * Average Radiated Noise Level (dB re 1 μ Pa) Total transits = 5134 Vancouver Fraser Port Authority | 16

Quiet operating options Voluntary ship slowdown in Salish Sea Why: To better understand the relationship between ship speed, underwater noise and potential effects on killer whales Where: ~16-30 nautical miles through critical whale feeding areas in Haro Strait and Boundary Pass Who: Over 80 organizations Monitoring: • Participation and vessel speeds • Ambient noise • Vessel source levels (2017 only) • Killer whale presence and behaviour Vancouver Fraser Port Authority | 22
