This project supports the analysis of marine benthic samples collected in the vicinity of Arthur Harbor, Antarctica, following an oil spill that resulted from the grounding of the Argentine supply ship Bahia Paraiso. The vessel grounded on January 28, 1989, and spilled an estimated 170,000 gallons of diesel and aviation fuel, which contaminated shorelines located up to 15 miles from the site of the accident. Although small in size, this spill is of significance because the affected areas include sites that are used extensively for fundamental scientific research and are composed of highly rich and productive assemblages of marine flora and fauna, which might include components that are very sensitive to unusual anthropogenic disturbances. The experimental design includes tests for possible oil-spill effects on these various components of the intertidal and subtidal communities. In addition, a great deal of importance is placed on basic research approaches to provide detailed descriptions of the structure and composition of these communities and to determine the role of natural environmental factors (e.g., depth, sediment type, organic input, environmental stability) in controlling patterns of spatial distribution and long-term variability (for those components having an historical data base). These studies will provide an empirical assessment of possible effects of the Bahia Paraiso oil spill on benthic components of the Arthur Harbor region. In addition, data from these studies will be extremely important in providing a basis for a more comprehensive understanding of the natural structure and dynamics of the Arthur Harbor benthic ecosystem, as well as a basis for comparison of the benthos with other marine ecosystems of the world. Finally, these analyses will provide baseline data to support continued studies of long-term, natural and man-induced variation in important living components of this diverse and productive region.

该项目支持分析在阿根廷供应船 Bahia Paraiso 搁浅导致漏油事件后在南极洲亚瑟港附近收集的海洋底栖样本。 该船于 1989 年 1 月 28 日搁浅，泄漏了约 170,000 加仑的柴油和航空燃油，污染了距离事故现场 15 英里的海岸线。 尽管规模不大，但这次泄漏意义重大，因为受影响的地区包括广泛用于基础科学研究的地点，并且由高度丰富和多产的海洋动植物群组成，其中可能包括对不寻常的人为因素非常敏感的成分。干扰。 实验设计包括测试溢油对潮间带和潮下群落的各个组成部分可能产生的影响。 此外，非常重视基础研究方法，以提供这些群落的结构和组成的详细描述，并确定自然环境因素（例如深度、沉积物类型、有机输入、环境稳定性）在生物群落中的作用。控制空间分布和长期变化的模式（对于那些具有历史数据库的组件）。 这些研究将对巴伊亚帕莱索漏油事件对亚瑟港地区海底成分可能产生的影响进行实证评估。 此外，这些研究的数据对于更全面地了解亚瑟港底栖生态系统的自然结构和动态以及底栖生物与世界其他海洋生态系统的比较提供基础非常重要。 。 最后，这些分析将提供基线数据，以支持对这个多样化和多产地区的重要生物组成部分的长期、自然和人为变化的持续研究。
