This project will map and characterize seafloor debris and associated benthic habitats and to contour the seafloor in the vicinity of McMurdo. Large numbers of barrels with unknown contents and other debris have been dumped or accumulated in the near-shore marine environment in McMurdo. This project will be the first critical step in determining the extent and risk to the environment of the potentially toxic debris. The principal investigators will use high resolution sidescan sonar, bathymetric profiling, scuba surveys, and photographic records to document the distribution and nature of debris while also mapping local physical habitats. The proposed work will also produce the first detailed bathymetric contour chart of the McMurdo area. Depth contour data are key elements in the development of accurate nearshore currents models needed to predict the movement of effluents from the new McMurdo sewer outfall. These data sets will be incorporated as the foundation elements in a comprehensive benthic Geographic information System to be maintained on existing National Science Foundation and Antarctic Support Associates computer facilities. Elements to be include will be the base map overlays for sidescan sonar images, depth, navigation tracks, debris, habitat type, community type sediment chemistry and pollutant loads, species lists and photographs.

该项目将绘制和描述海底碎片和相关的海底生境，并绘制麦克默多附近海底的轮廓。大量内容不明的桶和其他垃圾被倾倒或堆积在麦克默多近岸海洋环境中。该项目将是确定潜在有毒碎片的范围和对环境的风险的第一个关键步骤。主要调查人员将使用高分辨率侧扫声纳、水深剖面图、水肺调查和摄影记录来记录碎片的分布和性质，同时还绘制当地物理栖息地的地图。拟议的工作还将制作麦克默多地区的第一张详细的水深等高线图。深度等值线数据是开发准确的近岸水流模型的关键要素，该模型需要预测新的麦克默多下水道排污口的流出物运动。这些数据集将作为基础要素纳入一个综合海底地理信息系统，该系统将在现有的国家科学基金会和南极支助伙伴计算机设施上维护。将包括的内容包括侧扫声纳图像的底图覆盖、深度、航迹、碎片、生境类型、群落类型沉积物化学和污染物负荷、物种名单和照片。
