Enhancement and Maintenance of the Marine Seismic Processing System SIOSEIS

智力价值：该奖项支持的项目是海洋地震处理系统SIOSEIS的增强和维护。SIOSEIS是一个软件包，用于增强和处理Unix计算机(Mac OSX、Sun、PC-Linux、PC CYGWIN)上的海洋地震反射和折射数据。SIOSEIS在全世界范围内得到了积极的使用，在许多NSF资助的实验中，以及在几艘联合国日内瓦办事处的船只上。与所有软件一样，随着地震记录器、地震成像、导航和计算机技术的进步，SIOSEIS必须得到增强和维护。此外，最近的许多地震记录仪不以标准格式记录数据，需要定制软件来读取数据。SIOSEIS也成为了一种让科学家？更大的地震用户社区可以使用的研究算法。最近在SIOSEIS上的许多工作使科学家能够更快、更容易地产生地震图像，在许多情况下，他们仍然在海上。在海上处理地震数据使科学家能够根据当前的观测修改他们的科学计划。这一提议的智力优势在于，它将使新的地震处理算法可用，这些算法将允许科学家更快地创建更好的海洋地震反射图像。更广泛的影响：包括所有新的地震算法在内的SIOSEIS将通过网络免费提供给整个社区。这为海洋地震学提供了基础能力建设。

Intellectual Merit: The project supported under this award is for the enhancement and maintenance of the marine seismic processing system SIOSEIS. SIOSEIS is a software package used to enhance and manipulate marine seismic reflection and refraction data on Unix computers (Mac OSX, Sun, PC-Linux, PC CYGWIN). SIOSEIS is actively used worldwide, in numerous NSF funded experiments, and on several UNOLS ships. As with all software, SIOSEIS must be enhanced and maintained as advances are made in seismic recorders, seismic imaging, navigation, and computer technology. In addition, many of the recent seismic recorders do not record their data in standard formats and need custom software to read their data. SIOSEIS has also become a mechanism for making scientists? research algorithms accessible to the larger seismic user community. Much of the recent work on SIOSEIS has enabled scientists to produce seismic images more quickly and easily, in many cases while still at sea. Processing seismic data while at sea allows scientists to modify their science plan based on current observations. The intellectual merit of this proposal is that it will make new seismic processing algorithms available, and these algorithms will permit scientists to create better marine seismic reflection images more quickly. Broader Impacts: SIOSEIS including all of the new seismic algorithms will be freely available to the entire community over the web. This provides basic capacity building for marine seismology.
