Collaborative Research: A Deeptow Magnetic Study of the Jurassic Quiet Zone

由于侏罗纪洋壳只出现在少数几个地点，磁性侏罗纪平静带的性质尚未得到解决。在大洋钻探项目第801C孔获得了新的结果，表明侏罗纪内发生了多达6次极性反转或强度事件。该项目将进行一组近底深拖磁剖面的嵌套，覆盖801C附近的区域，然后向外扩展，将现有的1992年深拖线向南延伸到磁性粗糙-光滑边界，该边界被认为定义了该地区扩展序列的结束。深拖式磁法测量将提高信噪比，减少昼夜噪声问题，并缓解水深造成的衰减。

The nature of the magnetic Jurassic Quiet Zone is unresolved because Jurassic ocean crust occurs in only a few locations. New results have been obtained at Ocean Drilling Project Hole 801C suggesting up to six polarity reversals or intensity events within the Jurassic. This project will conduct a nested set of near-bottom deeptow magnetic profiles encompassing the region around 801C and then expanding out to extend the existing 1992 deeptow lines south to the magnetic rough-smooth boundary which is thought to define the end of the spreading sequence in the area. The deeptowed magnetic survey will boost the signal to noise ratio, reduce the diurnal noise problem and mitigate the attenuation due to water depth.
