Antarctic Stratigraphic Drilling: Cape Roberts Project

该奖项代表美国南极计划（USAP）参与罗伯茨角项目（CRP），这是一项在南极洲罗斯海西南部地区进行科学钻探的多国计划。 USAP将与新西兰、意大利、德国和英国的国家南极研究计划一起赞助这一项目。 新西兰南极计划（NZAP）是牵头组织，意大利和美国南极计划作为主要平等合作伙伴加入。 德国和联合王国是临时议程的次要提案国。 该奖项支持与美国研究者参与CRP相关的科学管理活动，沿着该奖项的是USAP为支持该项目而提供的后勤资源承诺。 CRP旨在解决与南极洲罗斯海部分的白垩纪至古近纪（1亿至3600万年前）历史以及南大洋早期发展有关的地球科学中的几个不同问题。 计划在维多利亚盆地西部1500米的地层中钻四个孔。 预计钻探工作将在两年内完成。 这将在南极夏季早期从陆地固定海冰中完成，预计钻井系统将产生约95%的岩心回收率。 该项目的科学目标包括：（1）确定西南极裂谷系罗斯海西部伸展板块碎裂的历史;（2）确定维多利亚陆地盆地和横贯南极山脉的沉降和出现历史;（3）确定与裂谷边缘隆起和盆地发展有关的侵蚀和沉积预算;（4）恢复西南太平洋靠近南极洲的第一个晚白垩世-古近纪层序，并试图恢复该地区的古气候和古海洋记录，（5）研究跨南极洲山脉的隆升与该地区气候变化的关系，（6）确定该层序中是否存在陆地或海洋冰川作用，（7）研究该地区的古气候和古海洋记录。7）记录了1亿年至3600万年前构造、沉积、古气候和海平面变化对生物进化、海洋地理学和海洋环流的影响。 这一跨学科研究计划将为地球系统建模提供有价值的新数据，并将加强海洋钻探计划和国际地圈生物圈计划等项目的全球科学议程。

This award represents participation of the United States Antarctic Program (USAP) in the Cape Roberts Project (CRP), a multi-national program of scientific drilling in the southwestern Ross Sea region of Antarctica. The USAP will join the national Antarctic research programs of New Zealand, Italy, Germany, and the United Kingdom in sponsoring this project. The New Zealand Antarctic Program (NZAP) is the lead organization and is joined by the Italian and US Antarctic Programs as major equal partners. Germany and the United Kingdom are minor sponsors of the CRP. This award supports the scientific management activities associated with participation of US investigators in the CRP and along with this award is a commitment for logistical resources from the USAP in support of the project. The CRP was conceived to address several diverse issues in geosciences related to the Cretaceous to Paleogene (100-36 million years ago) history of the Ross Sea sector of Antarctica as well as early development of the southern ocean. Four holes are planned to investigate a 1500 meter sequence of the western Victoria Basin. Drilling is expected to be accomplished over two years. It would be done from land-fast sea ice early in the Austral summer and the drill system is expected to produce about 95% core recovery. The scientific objectives of the project include: 1) establishing the history of the extensional plate fragmentation of the western Ross Sea part of the West Antarctic Rift System; 2) determining the subsidence and emergence histories of the Victoria Land Basin and the Transantarctic Mountains; 3) determining the erosional and depositional budgets associated with rift margin uplift and basin development; 4) recovering the first late Cretaceous to Paleogene succession from the southwest Pacific close to Antarctica and attempting to recover paleoclimatic and paleoceanographic records for the region; 5) investigating relationships between uplift of the Transantarctic M ountains and climatic changes in the region; 6) determining the presence or absence of terrestrial or marine glaciation in the succession; and 7) documenting the impact of tectonic, sedimentologic, paleoclimatic, and eustatic oscillations on biotic evolution, biogeography, and marine circulation between 100 and 36 million years ago. This interdisciplinary research plan will provide valuable new data for Earth systems modeling, and it will reinforce global science agendas of projects such as the Ocean Drilling Program and the International Geosphere-Biosphere Program.
