Steven N. WardEAR-0000978For the past several years, the Dr. Steven Ward has been involved in an ongoing collaborative research project with Dr. Kerry Sieh of California Institute of Technology that involves interpreting the various tectonic and non-tectonic signals recorded in coral microatolls sampled over the Sumatran subduction zone. The growth patterns of coral microatolls provide records of relative sea level variations over many decades. These relative vertical motions find their source in many tectonic and non-tectonic processes including: seismic earthquakes, slow/silent earthquakes (creep events), steady interseismic loading, seasonal and eustatic climatic effects, and local environmental influences. This project will fund work in geophysical, geodetic, and tectonic modeling to complement the geological and chemical strengths of the research team. This research will focus on the geophysical modeling, geodetic inference, and computer simulations of coral growth.

在过去的几年里，史蒂文·沃德博士一直与加州理工学院的克里·谢博士一起参与一项正在进行的合作研究项目，该项目涉及解释在苏门答腊俯冲带取样的珊瑚微环礁中记录的各种构造和非构造信号。珊瑚微环礁的生长模式提供了几十年来相对海平面变化的记录。这些相对垂直运动可以在许多构造和非构造过程中找到它们的来源，包括：地震、缓慢/无声地震（蠕变事件）、稳定的震间载荷、季节性和上升的气候影响以及局部环境影响。该项目将资助地球物理、大地测量和构造建模方面的工作，以补充研究团队的地质和化学优势。本研究将著重于珊瑚生长的地球物理模拟、大地测量推断及电脑模拟。
