Award is for a project to analyze multichannel seismic data acquired in the offshore Cantebury Basin, on the eastern margin of the South Island of New Zealand. Interpretation and mapping of the high resolution multichannel seismic profiles and integration with existing commercial and deep-penetration academic multichannel seismic profiles will allow evaluation of the relative roles of eustacy, tectonics, sediment supply and currents on stratigraphic development. The Cantebury Basin comprises a southern hemisphere counterpart to the New Jersey margin: both representing siliciclastic margins. The analysis will define the 3-D sequence geometries to reveal spatial and temporal changes in sequence geometry, and evaluate the relative importance of local versus global controls by using forward stratigraphic modeling to reproduce observed geometries.

该奖项是为了分析在新西兰南岛东部边缘的坎特伯雷盆地近海获得的多道地震数据的项目。高分辨率多道地震剖面的解释和绘图，以及与现有商业和深穿透学术多道地震剖面的结合，将能够评估海平面、构造、沉积物供应和洋流对地层发育的相对作用。坎特伯雷盆地由南半球与新泽西边缘相对应：两者都代表硅质碎屑边缘。该分析将定义三维层序几何结构，以揭示层序几何结构的空间和时间变化，并通过使用正演地层学模拟来再现观测到的几何结构，评估局部控制与全球控制的相对重要性。
