Collaborative Research: Analysis of the Lomonosov Ridge to Characterize Ancient Plate Boundaries in the Arctic: An Integrated Geophysical Study Utilizing SCAMP

这是一项与杜兰大学、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）合作的提案。1996年，美国国家科学基金会资助LDEO的科学家和工程师为sciex任务设计、制造和建造一套独特的仪器。海底表征和测绘吊舱（SCAMP）包括一个北极优化的seamarc型、侧扫条纹测深声纳（SSBS）、扫频或“chirp”高分辨率海底剖面仪（HRSP）、贝尔bgm3重力仪和数据采集和质量控制系统（DAQCS）。主要研究人员将安装SCAMP，在1999年SCICEX巡航期间操作正在进行的地球物理仪器，在巡航后从USS Hawkbill上移除仪器，并减少巡航期间收集的数据。数据的减少将由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关系的地球物理研究。据此推测，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。主要研究人员将分析SCICEX99期间收集的数据，以确定裂谷期间发展的结构，海洋-大陆边界的性质以及沿着罗蒙诺索夫海岭走向的构造过程的变化。

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.
