Capitol and the Washington Monument for 0.6 kilometers (an easy walk for over 10 million visitors a year), plaques would tactilely depict the scaled sizes and distances of the Sun, the planets, and their larger satellites in polished bronze. Porcelain enamel insets in the bronze would display...
This is one of the most interesting finds in Google Earth in quite some time. A few weeks ago a first time poster, called KenGrok, at the Google Earth Community (GEC)discovereda very exact scale model of some mountainous region located in the middle of a desolate area in north central C...
thanks totextbook representationsthat squeeze all the planets and their orbits into one page. Even at the speed of light, it takes more than 40 minutes to get from the Sun to Jupiter (a journey you canexperience in real-time here). And if you wanted to build a scale model of the Solar...
The nitrogen (N) cycle in terrestrial ecosystems is strongly influenced by resorption before litter fall and by mineralization after litter fall. Although both resorption and mineralization make N available to plants and are influenced by climate, their
River deltas rank among the most economically and ecologically valuable environments on Earth. Even in the absence of sea-level rise, deltas are increasingly vulnerable to coastal hazards as declining sediment supply and climate change alter their sediment budget, affecting delta morphology and possibly...
The Earth’s thermosphere and ionosphere constitute a dynamic system that varies daily in response to energy inputs from above and from below. This sy

The National Intertidal Digital Elevation Model (NIDEM) consists of four raster datasets (NIDEM, c and f below;unfiltered NIDEM, b and e below;NIDEM mask, a and d below; andNIDEM uncertainty) and two vector datasets (NIDEM waterline contoursandITEM v2.0 tidal modelling polygons). For co...
El Niño-Southern Oscillation (ENSO) exhibits diverse characteristics in spatial pattern, peak intensity, and temporal evolution. Here we develop a three-region multiscale stochastic model to show that the observed ENSO complexity can be explained by c
Since their recent first record within the Egyptian Nubian Shield, auriferous and uraniferous marbles (Au = 0.98–2.76 g/t; U = 133–640 g/t) have rarely been addressed, despite not only their probable economic importance but also the fact that it is a new genetic style of gold...
