August 20, 2018 — NOAA has presented awards to 13 global shipping firms for their commitment in helping prevent deadly ship collisions with whales. The companies participated in a Voluntary Speed Reduction initiative by slowing their ships to speeds of 10 knots (about 11.5 mph) or lower while transiting vessel traffic lanes outside the Golden Gate during whale feeding season, from May through mid-November.
The national marine sanctuaries of North-central California – Greater Farallones, Cordell Bank, and Monterey Bay sanctuaries – are prime foraging grounds for several endangered whale species, and through these same waters pass some of the heaviest shipping traffic in the world. In a spirit of “share the road,” the voluntary slowdown initiative is a collaboration between NOAA’s Office of National Marine Sanctuaries, the shipping firms, the Bay Area Air Quality Control District, and local NGOs.
The initiative program builds on decades of research by scientists and conservation groups who study the whales’ distribution patterns during their spring-through-fall foraging seasons along with vessel traffic patterns. It is modeled on similar efforts in Southern California and on the East Coast. In addition to providing whale protection benefits such as a reduction in risk of ship strike and a reduction in ocean noise, ships run more efficiently at slower speeds, which results in reduced greenhouse gas and particulate emissions and improves air quality for Bay Area residents.
This spring, five whales that had been killed by ship strike washed up on Bay Area beaches; three of these were endangered blue and fin whales. Several species are still recovering from whaling impacts, which had decimated most populations. But their recovery is not absolutely assured, since new threats have emerged in the meantime, primarily human-related.
