Satellite Gravimetry: Mass Transport and Redistribution in the Earth System

Quantifying Time-lapse Effects of Solution Squeeze Mining

SUMMARY In the northern part of The Netherlands the magnesium salts carnalite and bischofite are mined in a deep solution mine. For optimal production and also for environmental impact such as subsidence, it is vital to understand the process of salt production. To this aim, it is studied whether seismic in time-lapse mode may help to visualize and quantify the changes due to the salt productio...

Visualizing and quantifying movement from pre-recorded videos: The spectral time-lapse (STL) algorithm

When studying animal behaviour within an open environment, movement-related data are often important for behavioural analyses. Therefore, simple and efficient techniques are needed to present and analyze the data of such movements. However, it is challenging to present both spatial and temporal information of movements within a two-dimensional image representation. To address this challenge, we...

Validation of Oceanic Mass Changes derived from GRACE Gravimetry

The satellite mission GRACE (Gravity Recovery and Climate Experiment) provides monthly solutions of the global gravity field of the Earth. Temporal variations in gravity reflect mass redistributions over the Earth. Those mass movements are caused by physical phenomena such as ice sheet dynamics, accumulation of hydrological masses over land, the dynamics in the solid Earth and the dynamics in t...

Quantifying Preferences for Redistribution

This paper constructs quantified measures of preferences for redistribution using survey data from seven OECD countries in which respondents were asked how much in taxes individuals earning given levels of income “should” pay. The resulting preferred tax rates generate reasonable budget sets, are consistent with observed tax rates, and correlate closely with conventional categorical preference ...
