pollution

As the vessel speeds through the icy water in pursuit of whales, one researcher cocks and loads a crossbow, waiting for a dorsal fin to surface and the perfect time to strike. It’s a scene reminiscent of America’s maritime past, when commercialized whalers harpooned whales from wooden rowboats to harvest their oils and bones. Industrial whaling nearly wiped out some of America's whales, but today when scientists approach marine mammals such as whales and dolphins in small boats, they are on the hunt for information that helps protect them.

Does a killer whale instinctively know how to avoid oil spilled on the surface of its watery home? At the time of the Exxon Valdez oil spill 23 years ago, scientists and oil spill experts presumed that the answer was "yes."

During Whale Week (Feb. 10-14), NOAA’s Office of Response and Restoration is taking a closer look at the different pollutants affecting whales, and what OR&R and our partners are doing to help.

There is no one-size-fits-all approach to environmental assessments for oil spills or hazardous waste events. We must therefore custom-tailor our technical approach for each pollution incident.

We first determine whether impacts to natural resources have occurred and whether it is appropriate to proceed with a Natural Resource Damage Assessment (NRDA). We collect time-sensitive data, evaluate available research and information about the type of injury, and determine what species and habitats are likely to have been affected. If we determine that habitats, wildlife or human uses have been harmed or could experience significant impacts, we often proceed with a full damage assessment.

To paraphrase an old saying, “There’s no use crying over spilled oil.” But many people in Washington worry a lot about oil pollution in Puget Sound and other coastal waters around the state.

What many don’t realize is that the biggest source of oil spills to date in Puget Sound isn’t tankers and freighters but small recreational and commercial vessels. Small oil spills from these types of vessels account for 75 percent of the oil spilled in local waters over the last 10 years.
