Global and Local Controls on Depositional Cyclicity: The Canterbury Basin, New Zealand

9731031 Fulthorpe该奖项将支持海洋地震反射计划，以研究全球（海平面）和当地（构造，沉积物供应率和洋流）控制的相互作用，负责大陆边缘沉积物沉积和旋回性。位于新西兰南岛东部边缘的坎特伯雷盆地是研究这些控制环境因素的绝佳地点。新近纪沉积物的高供给率导致了异常高的频率（0.5-1百万年）的保存。周期性），沉积旋回性的地震可分辨记录。沉积作用和加积作用产生了具有保存完好且未被侵蚀刨平的内部结构的沉积几何形状。在一项实地方案中，将使用拉蒙特-多尔蒂地球观测站操作的R.V Ewing收集和分析高分辨率多道地震数据。除了从数据中得出的基本科学分析外，这项研究还将用于国际海洋钻探计划的未来钻探计划。 ***

9731031 Fulthorpe This award will support a marine seismic reflection program to examine the interplay of global (eustacy) and local (tectonics, sediment supply rate and ocean currents) controls responsible for continental margin sediment deposition and cyclicity. The Canterbury Basin, on the eastern margin of the South Island of New Zealand, is an excellent location in which to study these controlling environmental factors. High rates of Neogene sediment supply have resulted in the preservation of an unusually high frequency (0.5-1 m.y. periodicity), seismically resolvable record of depositional cyclicity. Progradation and aggradation have produced depositional sedimentary geometries with internal structures that are well-preserved and unplaned by erosion. High resolution multi-channel seismic data will be collected and analyzed during a field program using the R.V Ewing operated by Lamont-Doherty Earth Observatory. In addition to basic scientific analysis to be derived from the data, this research will also be used to plan future drilling by the international Ocean Drilling Program. ***
