The Bahia Paraiso Oil Spill: Impact on a Southern Seabird Community

1989年1月28日，阿根廷补给船巴伊亚号帕拉伊索号 在南极洲帕尔默站附近搁浅， 柴油、喷气燃料和重质润滑油进入海洋 环境 在喂食的同时， 该地区六个最丰富的物种的萌芽和扩散阶段 36，000 - 43，000只雏鸟和成鸟暴露于 油 这项研究的重点是确定这种影响， 泄漏对帕尔默地区海鸟数量的影响 从 1987年至1989年期间在帕尔默站进行的先前研究， 目前的数据丰富，繁殖成功，饮食和生长 这个海鸟群落中更多成员的死亡率， 包括1988年标记的小鸡群（未接触石油）， 1989年（接触石油）。 该数据将用作基线 为评估海鸟而进行的比较研究中的资料 该地区的死亡率，并确定人口的潜力， 复苏 类似的基线数据在下列国家中很少有， 石油对整个海鸟群落的影响研究。 的 因此，拟议的研究变得独特的价值，不仅在条款 评估石油泄漏对一个相对 原始的极地海鸟群落，但作为一个潜在的来源， 一般而言，海鸟影响研究的关键数据。

On 28 January 1989, the Argentine supply ship Bahia Paraiso ran aground near Palmer Station, Antarctica, spilling 180,000 gallons of diesel fuel, jet fuel and heavy lubricants into the marine environment. The spill, which coincided with the feeding, fledgling and dispersal stages of the area's six most abundant seabird species, exposed 36,000-43,000 chicks and adults to the oil. The focus of this study is to determine the impact this spill has had on seabird populations in the Palmer area. From prior research at Palmer Station during 1987-1989, there is current data on the abundance, breeding success, diets and growth rates of the more numerous members of this seabird community, including marked chick cohorts from 1988 (not exposed to oil) and 1989 (exposed to oil). This data will be used as baseline information in a comparative study designed to assess seabird mortality in the area and determine the population's potential for recovery. The availability of similar baseline data is rare among oil impact studies on seabird communities as a whole. The proposed study thus becomes uniquely valuable, not only in terms of assessing the impacts of an oil spill on a comparatively pristine polar seabird community, but as a potential source of critical data for seabird impact studies in general.
