Reconnaissance of Background Infrasound at Selected Future IMS Locations, Atlantic Ocean
Abstract
This contract yielded infrasonic reconnaissance at several sites that have been selected for installation of infrasonic arrays as part of the International Monitoring System (IMS). Specifically, we have installed temporary stations at three islands in the Atlantic Ocean. The primary goal was to broadly characterize the variability of the natural background infrasound on these in a way that could be helpful the deployers of the future monitoring facilities. These islands each offer a variety of environmental settings and are inherently different from each other in terms of natural characteristics such as size, shape, wind, weather, topography, and vegetation. As a result, this study has also provided insight about parameters that affect the quality of infrasonic measurements on relatively small islands. We have assessed the utility of infrasonic monitoring stations on these island 5 and have found suitable locations for all array elements. The locations are Ascension Island, Sao Miguel Island, Azores and Maio Island, Republic of Cape Verde. This report separates results from each island chapter.
