New Capabilities in Polar Qualified Very Broadband Seismic Instrumentation
Abstract
The 2003 SEAP (The Structure and Evolution of the Antarctic Plate) conference in Boulder, Colorado produced an influential report, "Antarctica Array: A Unique Perspective on the changing Earth". SEAP laid out an ambitious vision of seismic and geodetic arrays to study the Antarctic plate and its structure and evolution, and the Antarctic seismological environment using components and approaches influenced by the concurrent planning of EarthScope. Elements addressing SEAP science motivations were funded by NSF and substantial improvements in year-round data return were realized by the time of the 2007-2009 IPY (International Polar Year) and thereafter. However, these engineering improvements in power, (limited) telemetry, and deployment systems have taken many years to achieve reliability and data quality metrics that are comparable to those of lower latitude deployments. Recently developed polar rated broadband seismic systems have much wider bandwidth, lower self-noise, and greatly reduced SWaP (size, weight, and power). These instruments provide the opportunity to realize higher-density high quality modern data acquisition that is relevant to solid Earth, glaciological, and/or climate-related studies, and to broadly further the autonomous and real time collection of extremely low noise observations in polar regions. We will discuss these new instruments, and their capabilities and possibilities in the context of further improving present polar instrument pools to address SEAP Conference and other polar science initiatives that have not yet been realized.
