This proposal (SWATH D) focuses on the provision of seismic data from a dense seismic network in the Central and Eastern Alps. This dense deployment of 154 stations will complement the larger-scale AlpArray network (backbone). SWATH D will provide high-resolution images from the surface into the upper mantle. SWATH D focuses on a key area of the Alps where e.g. the hypothesized flip in polarity is suggested to occur, and where TRANSALP has imaged a jump in the Moho. The data created in this project will be used directly by 20 individual proposals of the SPP, and data products derived from it will contribute to an additional 17 proposals. SWATH D is thus an important link within the SPP 4D-MB and the international AlpArray community and a scientific service to a majority of the proposals within the SPP community. We will also closely cooperate with the proponents of SWATH C, covering the area south of SWATH D, down to the Apennines. We describe here in compact form the state of the art and preliminary work following the overview given by Handy et al. (2015). Since each of the 35+ proposals using SWATH D data or derived products will describe their scientific objectives and work programs in their individual proposals, we only summarize the key scientific targets of SWATH D, and focus otherwise on describing the activities required to acquire this high quality dataset.

该提案（SWATH D）侧重于提供来自阿尔卑斯中部和东部密集地震网的地震数据。154个站点的密集部署将补充更大规模的AlpArray网络（骨干）。SWATH D将提供从地表到上地幔的高分辨率图像。SWATH D聚焦于阿尔卑斯山脉的一个关键区域，例如，假设极性翻转可能发生在那里，TRANSALP在那里成像了莫霍的跳跃。该项目中创建的数据将直接用于SPP的20个单独提案，从中获得的数据产品将用于另外17个提案。因此，SWATH D是SPP 4D-MB和国际AlpArray社区之间的重要联系，也是SPP社区中大多数提案的科学服务。我们还将与SWATH C的支持者密切合作，覆盖SWATH D以南直至亚平宁山脉的地区。根据Handy等人（2015）给出的概述，我们在这里以紧凑的形式描述了目前的技术状况和初步工作。由于使用SWATH D数据或衍生产品的35多个提案中的每一个都将在其单独的提案中描述其科学目标和工作计划，因此我们只总结SWATH D的关键科学目标，而将重点放在描述获取高质量数据集所需的活动上。
