The Earth’s hum: the excitation of Earth normal modes by ocean waves
S U M M A R Y The recent discovery that the seismic normal modes of the Earth are excited to a nearly constant level during seismically quiet days (‘the hum of the Earth’) has lead to much speculation as to what drives the observed background in the absence of large earthquakes. Other authors have shown that the hum cannot be explained by the many small earthquakes occurring each day and have a...
متن کاملComputational earth system science
Of the many fields of science in which increased numerical simulations and information technology have accelerated recent developments, perhaps none holds more promise than computational earth system science, a field of research within the new science of GeoComplexity. In the past, researchers observed physical and chemical processes to clarify the physics of such natural systems as earthquake ...
متن کاملThe rise of hydrological science off Earth
It has been a long lasting interest to understand the laws that underlie water movement on Earth with the purpose to control it and make use of it. It is now recognized that water is not exclusive to the Earth but, rather, is a major constituent of the matter in the universe and may be a proxy for life in other planets as well. In this paper, we reflect on the need to expand the boundaries of t...
متن کاملGENESIS: The General Earth Science Investigation Suite
GENESIS is a NASA-sponsored partnership between the Jet Propulsion Laboratory, academia, and three NASA data centers to develop a new suite of web services tools to facilitate multi-sensor investigations in Earth System Science. Residing within a framework known as SciFlo, these tools will offer versatile operators for data access, subsetting, registration, fusion, compression, and advanced sta...
متن کاملSemantics and the Earth Science Markup Language
Earth science data is archived and distributed in many different formats. These formats vary from character format, packed binary, and "standard" scientific formats to selfdescribing formats. This heterogeneity is partly due to historical and partly practical reasons. Since there is not a single standard format that meets the needs of the entire Earth Science community, most scientists choose t...
