The new IMGC-02 transportable absolute gravimeter: measurement apparatus and applications in geophysics and volcanology

Annals of Geophysics, 2008
The research carried out at the Istituto Nazionale di Ricerca Metrologica (formerly Istituto di Metrologia «G. Colonnetti») aiming to develop a transportable ballistic absolute gravimeter ended with a new version of the instrument, called the IMGC-02. It

Towards an Operational Use of Geophysics for Archaeology in Henan (China): Methodological Approach and Results in Kaifeng

Remote Sensing, 2017
One of the major issues in buried archeological sites especially if characterized by intense human activity, complex structures, and several constructive phases, is: to what depth conduct the excavation?

An Ensemble Algorithm Based Component for Geomagnetic Data Assimilation

Terrestrial, Atmospheric and Oceanic Sciences, 2015
Geomagnetic data assimilation is one of the most recent developments in geomagnetic studies. It combines geodynamo model outputs and surface geomagnetic observations to provide more accurate estimates of the core dynamic state and provide accurate ...

International geophysics: Geophysical interests of IUGS

Eos, Transactions American Geophysical Union, 1969
The International Union of Geological Sciences (IUGS) was born in 1961, an offspring of the International Geological Congress (IGC) founded in 1878. IUGS was immediately accepted into the International Council of Scientific Unions (ICSU) and promptly became a working partner in a number of inter‐union and ICSU activities. It thereby achieved one of the

Fifty years of research on the Joulters ooid sandbody—Impact on carbonate sedimentology and diagenesis and lessons learned from an invaluable analogue

The Depositional Record, EarlyView.
The Joulters ooid sandbody of northern Great Bahama Bank is a vast expanse of muddy ooid sands partly rimmed by clean ooid sands and formed into a relatively thick layer of significant extent. Knowledge of the development of depositional and diagenetic patterns in the Joulters example has forwarded our general understanding of carbonate sedimentology ...

Bahaman patch reefs: Numerous and neglected

The Depositional Record, EarlyView.
Abstract Phanerozoic patch reefs are extensively studied because they are abundant and are potential reservoirs for valuable fluids. In contrast, geologic studies of modern reefs have largely focused on platform margins, leaving patch reefs comparatively neglected. What conditions favour patch‐reef development?
