9314502 Orcutt The broad motivation for this study is to further understanding of the relationship between the nature of the seismicity (depth, mechanisms, spatial-temporal behavior), the character of ridge axis morphology, and the generation of acoustic T-waves along the Iceland-Svalbard plate boundary. The recent availability of several new seismic/acoustic data sets provides an exciting opportunity for a well-constrained investigation: the Norwegian land-based seismic array data, the U.S. Navy hydrophone array data, and detailed data on the plate geology and tectonics.
