SCAMP: Phase II Installation of Geophysical Survey Instrumentation for SCICEX

海底表征和测绘吊舱（SCAMP）项目的第二阶段将在美国海军637级潜艇USS HawkBill上建造，组装和完成侧扫描条带测深声纳（SSBS）和高分辨率海底剖面仪（HRSP）吊舱的安装。 SCAMP的完成将增加目前在NSF/ONR潜艇计划SCICEX中使用的生物，物理，化学和地球物理调查仪器的现有补充，从而产生新的数据，这些数据以前从未在北极深处收集过：条带反向散射和测深以及海底剖面仪数据。 在对SCAMP进行码头边和海上测试后，该潜艇将于1998年6月从檀香山部署在前往北极的非机密SCICEX巡航中。 潜艇在浮冰下的机动性以及美国海军部署带有主动声纳的USS HawkBill的意愿，使这成为绘制北冰洋深海地图的绝佳机会。 SCAMP将提供必要的数据集：海底取样和北极钻探的地点选择，这将揭示北极的古海洋学历史。 精确的数字地形模型，用于模拟北极的海洋环流并了解其对全球气候的影响。 扩张最慢的大洋中脊-北极大洋中脊-的详细地图。 绘制冰川周边地貌（冰山犁痕等）在陆架和海盆高原上，沉积物的物质消耗特征、深盆的河道和沉积物波动特征，这些特征将扩大我们对北极更新世历史和全新世沉积物流入海盆的认识。 对美亚盆地历史的研究，该盆地被可能是白垩纪时代的洋壳包围，但没有已知的板块边界。

Phase two of the Seafloor Characterization and Mapping Pod (SCAMP) project will construct, assemble and complete the installation of the Sidescan Swath Bathymetric Sonar (SSBS) and the High Resolution Sub-bottom Profiler (HRSP) pods on the USS HAWKBILL, a US Navy 637-class submarine. Completion of SCAMP will augment the existing complement of biological, physical, chemical and geophysical survey instrumentation currently utilized in the NSF/ONR Submarine program SCICEX, resulting in new data, never before collected in the deep Arctic: swath backscatter and bathymetry as well as sub-bottom profiler date. The submarine will deploy on the unclassified SCICEX cruise to the Arctic in June 1998 from Honolulu, following dockside and at-sea testing of SCAMP. The mobility of the submarine below the pack ice and the willingness of the US Navy to deploy the USS HAWKBILL with active sonars, makes this an exceptional opportunity to map the deep Arctic Ocean. SCAMP will provide data sets necessary for: Site selection for bottom sampling and Arctic Drilling, which will expose the paleo-oceanographic history of the Arctic. Accurate digital terrain models required for modeling ocean circulation in the Arctic and understanding it's impact on global climate. Detailed mapping of the slowest spreading mid-ocean ridge, the Arctic Mid-Ocean Ridge. Mapping of peri-glacial features (iceberg plow marks etc.) on the shelves and high plateau in the basin, mass wasting features, channels and sediment waves in the deep basin, which will expand our knowledge of the Pleistocene history of the Arctic and sediment fluxes into the basin during the Holocene. Study of the history of the Amerasian Basin, which is floored by oceanic crust of probable Cretaceous age, but has no known plate boundaries.
