This is a collaborative proposal with the Tulane University, University of Hawaii's Hawaii Mapping and Research Group (HMRG) and Lamont-Doherty Earth Observatory (LDEO). In 1996, the National Science Foundation funded scientists and engineers LDEO to design, fabricate, and construct a unique set of instruments for SCICEX missions. The Seafloor Characterization and Mapping Pod (SCAMP) includes an Arctic optimized SeaMARC-type, Sidescan Swath Bathymetric Sonar (SSBS), a swept frequency or "chirp" High Resolution Subbottom Profiler (HRSP), a Bell BGM-3 gravimeter, and Data Acquisition And Quality Control System (DAQCS). The Principal Investigators will install SCAMP, operate the underway geophysical instrumentation during the 1999 SCICEX cruise, remove the instrumentation from the USS Hawkbill after the cruise and reduce the data collected during the cruise. Reduction of the data will be done by the Principal Investigator from HMRG. The scientific part of the proposal is a geophysical study of the structure of the Lomonosov Ridge and the relationship between it and the Amerasian and Eurasian Basins. It is speculated that the Lomonosov Ridge is a continental crustal structure and that it is the continental margin for both the Amerasian and Eurasian Basins. The Principal Investigators will analyze the data collected during SCICEX99 to determine the structures developed during rifting, the nature of the ocean-continent boundary and variations in tectonic processes along the strike of the Lomonosov Ridge.

这是与杜兰大学，夏威夷大学的夏威夷映射与研究小组（HMRG）和Lamont-Doherty Earth天文台（LDEO）的合作提议。 1996年，国家科学基金会资助了科学家和工程师LDEO，设计，制造和构建了Scicex任务的独特工具。 海底表征和映射荚（SCAMP）包括北极优化的Seamarc-Type，Sidscan Swath Bathymetric Sonar（SSBS），一个扫描的频率或“ Chirp”高分辨率subbottom profiler（HRSP），Bell BGM-3 Gracimeter和Data Recalisition and Data Coceition and Data Contric and Control和DAQCS（DAQC）。 首席调查人员将安装SCAMP，在1999年Scicex巡游期间运行地球物理仪器，在巡航后从霍克比尔号卸下仪器，并减少在巡航过程中收集的数据。 数据的减少将由HMRG的主要研究人员完成。 该提案的科学部分是对Lomonosov Ridge结构的地球物理研究，以及IT与阿美拉萨斯和欧亚盆地之间的关系。 据推测，Lomonosov山脊是一种大陆地壳结构，它是阿美拉萨斯和欧亚盆地的大陆边缘。 主要研究人员将分析SCICEX99期间收集的数据，以确定裂谷期间开发的结构，海洋边界的性质以及沿Lomonosov Ridge罢工的构造过程的变化。
