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.

这是杜兰大学、夏威夷大学夏威夷测绘与研究小组 (HMRG) 和拉蒙特-多尔蒂地球观测站 (LDEO) 的合作提案。 1996 年，美国国家科学基金会资助 LDEO 的科学家和工程师为 SCICEX 任务设计、制造和建造一套独特的仪器。 海底表征和绘图吊舱 (SCAMP) 包括北极优化的 SeaMARC 型、侧扫条带测深声纳 (SSBS)、扫频或“啁啾”高分辨率海底剖面仪 (HRSP)、贝尔 BGM-3 重力计和数据采集器和质量控制系统（DAQCS）。 首席研究员将安装 SCAMP，在 1999 年 SCICEX 巡航期间操作正在运行的地球物理仪器，在巡航结束后从 USS Hawkbill 上拆除仪器，并减少巡航期间收集的数据。 数据的缩减将由 HMRG 的首席研究员完成。 该提案的科学部分是对罗蒙诺索夫海岭的结构及其与美亚盆地和欧亚盆地之间的关系进行地球物理研究。 据推测，罗蒙诺索夫海岭是一个大陆地壳结构，是美亚盆地和欧亚盆地的大陆边缘。 首席研究员将分析 SCICEX99 期间收集的数据，以确定裂谷期间形成的结构、海洋-大陆边界的性质以及沿罗蒙诺索夫海岭走向的构造过程的变化。
