Upgrade of Department of Geosciences Digital Mapping and Modeling Laboratory at the University of Massachusetts Amherst

马萨诸塞大学阿默斯特大学地球科学系数字测绘和建模实验室的升级将提供一个综合培训和研究设施，在这里，一系列地球科学领域的研究生和高级本科生可以利用最先进的计算机协同解决问题。在这项工作中，研究领域包括(1)集成了数值数据、电影、动画、图像和其他多媒体数据集的计算机制图和可视化；(2)了解地下水环境中主要由水驱动的质量和能量运动的反馈；(3)了解海岸、河口和河流的过程，重点是泥沙的输运和沉积；(4)通过使用尖端软件可视化和开发三维地质断层的模型，解决它们如何形成岩石的问题，以提高对古气候、海岸形态和海平面上升及其相互关系的理解；(4)通过使用尖端软件可视化和开发它们的模型，并解决它们如何形成岩石，来了解三维地质断层的演化，以及(5)应用地质约束建立气候-冰盖耦合模型，以了解南极冰盖6000万年的历史，以及海冰反馈在其演化中所起的作用。所有这些研究领域都对公众具有实际意义。例如，通过添加创建地图上所示地质的过程的电影和动画，公众可以立即了解形成所见地物的过程。我们对沿海过程的了解，例如那些导致当地海平面变化的过程，可能会对土地利用规划产生直接影响。同样，我们对断层上给定运动的可能位置、大小和几何形状的理解也可能对土地利用规划产生影响，以突出这五个领域中的三个。

The upgrade of the Digital Mapping and Modeling Laboratory in the Department of Geosciences at the University of Massachusetts Amherst will provide an integrated training and research facility where graduate and advanced undergraduate students, in a range of geoscience fields, can synergistically engage in problem solving using state-of-the-art computers. In this work, the areas of research include (1) computer mapping and visualization that integrate numerical data, movies, animations, images, other multi-media datasets (2) understanding the feedback in the largely water-driven movement of mass and energy in subsurface environments, (3) understanding coastal, estuarine and fluvial processes, with a focus on sediment transport and deposits, to improve the understanding of paleoclimate, coastal morphology, and sea-level rise, as well as their interconnections, (4) understanding the evolution of three-dimensional geologic faults by using cutting-edge software to visualize and develop models of them, and solve for how they deform rocks, and (5) applying geologic constraints to create a coupled climate-ice sheet model to understand, for example, the 60-million-year history of the Antarctic ice sheet, and role played by sea ice feedback in its evolution.All of these areas of research have a component of practical significance to the public. For example, by including movies and animations of the processes that created the geology shown on maps, the public can gain an immediate understanding of the processes that formed the features seen. Our understanding of coastal processes, for example those that lead to local changes in sea-level, may have a direct impact on land-use planning. Similarly, our understanding of the possible location, magnitude, and geometry of a given movement on a fault could also have an impact on land use planning, to highlight three of these five areas.
