This project will document the micro and macrofaunal content of the McMurdo Ice Shelf. Holocene fossil material has been lifted from the seafloor at the southern limits of McMurdo Sound and moved to the surface of the ice shelf during ablation. Current investigations involve attempts to characterize assemblages in different areas of the shelf in terms of bathymetry, substrate, and degree of faunal degradation. This project will include systematic and isotope studies in the laboratory. Although debris-rich ice shelves are rare in Antarctica today, the degree of transport of material (including fossil material) from the continental interior to the continental margin during the Cenozoic implies McMurdo Ice Shelf-like bodies were quite common in the past. The Holocene McMurdo Ice Shelf is the best available analog for these earlier Cenozoic ice shelves.

该项目将记录麦克默多冰架的微型和大型动物内容。 全新世化石材料已从麦克默多海峡南部边界的海底升起，并在消融过程中移动到冰架表面。 目前的研究包括尝试根据水深、基质和动物退化程度来描述陆架不同区域的组合特征。 该项目将包括实验室的系统研究和同位素研究。 尽管富含碎片的冰架在今天的南极洲很少见，但新生代期间物质（包括化石物质）从大陆内部到大陆边缘的迁移程度意味着麦克默多冰架状物体在过去相当普遍。 全新世麦克默多冰架是这些早期新生代冰架的最佳模拟。
