A study conducted by students and researchers from the Sea Around Us project found that the world's monitored seabird populations have fallen nearly 70 percent since the s. That marks a . Current threats to seabird populations in the Gulf of the Farallones region include effects of contaminants from San Francisco Bay, overfishing, low-level or “chronic” oil pollution, and mortality associated with gillnetting in Monterey Bay. Declines in some seabird populations in the gulf are occurring because of these and other effects.

These threats include the full range of stressors.
An oil spill is the release of a liquid petroleum hydrocarbon into the environment, especially the marine ecosystem, due to human activity, and is a form of term is usually given to marine oil spills, where oil is released into the ocean or coastal waters, but spills may also occur on spills may be due to releases of crude oil from tankers, offshore platforms, drilling. The study updated previous work on seabird sensitivity to wind farms in Scottish waters to include more recent demographic data and defining populations relevant to English territorial waters. This enables comparison to be made of relative species sensitivity in English and Scottish by:

Get this from a library. The relative sensitivity of seabird populations in Alaska to oil pollution. [Donald J Hansen; Alaska Outer Continental Shelf Office.] -- Consolidates information on the potential effects of oil pollution on marine and coastal birds from oil and gas lease sales pending for the outer continental shelf areas of Alaska.
Alaska's Vast Seabird Population. About 50 million seabirds nest on Alaska's coast each summer. This is 87% of all the seabirds in the United States. (Hawaii has the second most seabirds of any state.) Alaska's seabirds nest in more than seabird colonies around the coast. Alaska has many seabirds for several reasons.
Seabirds are the most visible and vulnerable victims of oil pollution in marine waters. As demonstrated by the "Exxon Valdez" spill (Piatt et al. ), we cannot predict when or where an accident leading to pollution might occur in Alaska, or where oil will eventually end up traveling from a point source of pollution.
It is therefore prudent to document the abundance and distribution of Author: John F. Piatt, R. Glenn Ford. The Effects of Chronic Oil Pollution on Seabird Populations.

For the study, the researchers compiled information on more than seabird populations from around the world, representing 19 percent of the global seabird population. - never a "normal" year to serve as a baseline for comparison of seabird growth, survival, and population dynamics - Seabirds are adapted to survive in highly stochastic environments •Difficult to tease apart cause and effect relationships between weather events and seabird life-history traits.
IMPACT OF OIL POLLUTION ON SEABIRD POPULATIONS What matters in the long-term is the effect of pollutants on the population and the community (ICES, ; GESAMP, ), and the significance of the mortality of seabirds from oil pollution or other causes depends on the population dynamics of the species in question and the role of that species Cited by: In turn, long-term effects of major oil spill events and chronic oil pollution are discussed as potential reasons for declines in bird populations (Votier et al., ).
These authors found that winter mortality of adult guillemots was doubled by major oil pollution incidents in combination with effects of the North Atlantic Oscillation (NAO). Large numbers of seabirds may be killed from time to time by individual incidents of oil pollution, and throughout the year, especially in winter, dead seabirds, many of them oiled, are washed up o.
About million seabirds reside in marine waters of Alaska during some part of the year. Perhaps half this population is composed of 50 species of nonbreeding residents, visitors, and breeding species that use marine habitats only seasonally (Gould et al.

Chemical analyses of the oils on dead or moribund seabirds from Atlantic Canada during the winter of – indicated that some of the birds were contaminated with oil spilled by the Argo Merchant grounding, some by oil probably from the Grand Zenith sinking, and still others by oil from various small local spills of unknown origin.

Oil spills often spell disaster for marine birds caught in slicks. However, the impact of oil pollution on seabird population parameters is poorly known because oil spills usually occur in wintering areas remote from breeding colonies where birds may be distributed over a wide area, and because it is difficult to separate the effects of oil pollution from the effect of natural environmental Cited by: Beginning inlarge numbers of dead seabirds have been appearing on beaches in most marine areas of Alaska.
Although seabird die-offs are known to occur sporadically (e.g.,/, and ) in Alaska, these recent die-offs have been distinguished from past events by their increased frequency, duration, geographic extent, and number of different species involved.
