NOAA Issues Final Killer Whale Vessel Regulations

New regulations to protect killer whales in inland waters of Washington State from the effects of various vessel activities.

1. vessels must not approach any killer whale within 200 yards
2. vessels must stay out of the path of oncoming whales out to 400 yards.

Website for more information on the vessel regulations.

Killer Whale Exhause Exposure

Cara L. Lachmuth, Lance G. Barrett-Lennard, D.Q. Steyn, William K. Milsom (2011) Estimation of southern resident killer whale exposure to exhaust emissions from whale watching vessels and potential adverse health effects and toxicity thresholds. Marine Pollution Bulletin, 28 January 2011.

Southern resident killer whales in British Columbia and Washington are exposed to heavy vessel traffic. This study investigates their exposure to exhaust gases from whale-watching vessels by using a simple dispersion model incorporating data on whale and vessel behavior, atmospheric conditions, and output of airborne pollutants from the whale-watching fleet based on emissions data from regulatory agencies. Our findings suggest that current whale-watching guidelines are usually effective in limiting pollutant exposure to levels at or just below those at which measurable adverse health effects would be expected in killer whales. However, safe pollutant levels are exceeded under worst-case conditions and certain average- case conditions. To reduce killer whale exposure to exhaust we recommend: vessels position on the downwind side of whales, a maximum of 20 whale-watching vessels should be within 800 m at any given time, viewing periods should be limited, and current whale-watch guidelines and laws should be enforced.

J1/Ruffles Missing

Ruffles / J1

The 60 year old killer whale Ruffles/J1 was last seen on Novermber 21st, 2010. He would travel with Granny/J2 (100 years old) who has been seen several times since without Ruffles. Male longevity, typically is less than females, averaging about 29 years, some live well into their 40s and up 50-60 years of age. The average lifespan for females is about 50 years, however some may reach 80-90 years of age (Ford et. al. 2000).

Offshore Killer Whales eating Sleeper Sharks

Offshore Killer Whale Teeth

John Ford and colleagues were observing the whales, they noticed them engaging in feeding behaviour. Immediately following this they discovered chunks of pink meat on the water’s surface which upon genetic analysis turned out to be the meat of at least 16 different Pacific sleeper sharks (Somniosus pacificus).

Steller Sea Lions

The Social-10 objective is to estimate the risk and minimize the impact of human sound and military sonar. It includes suction-cup tagging, listening, and tracking of whales, dolphins, seals, and sea lions. Preliminary findings show marine mammal response varied by species, behaviour, and sound type. For example, beaked whales were more responsive than other species, like pilot whales.
