Emperors of the Extreme

submitted by: ucsandiego

Emperor penguins can flourish in locales where few other animals roam. But scientists now wonder if they can adapt to a new threat: climate change.

A Physical Model for Widespread Near-Surface and Fault Zone Damage Induced by Earthquakes - Seismic observations indicate that material velocities at shallow depths decrease over a large area after large earthquakes. The reductions are widespread, and occur at distances of up to several source dimensions. A persistent low-velocity fault zone has also been documented extensively from seismic and geodetic observations, in which the velocity drops further after large earthquakes. Dynamic...

Tidal Bore on the Severn River - Tides progress up the Severn River in SW England as a tidal bore moving faster than 6 m/s. During spring tides, the leading edge of the bore can be up to 2 m high, taking more than an hour to travel from the lower portion of the river to past Gloucester. This is sufficient to attract surfers from around the world. The North Atlantic amphidromic system interacts with the broad continental shelf around the U.K. to produce a complicated field of large tidal...

Development Geology of the Antelope Shale: Section 1Y, Cymric Field, San Joaquin Valley, California - The Antelope Shale reservoir in Section 1Y, Cymric Field, San Joaquin Valley, California is one of Chevron’s key assets. The reservoir is a Miocene Age member of the Monterey Formation composed of Opal A (amorphous), Opal CT (cristobalite, tridimite) and Quartz phase diatomaceous deep water sediments. The Antelope Shale has an anomalously high average porosity of 58%, high initial oil...

With advances in computational capabilities and refinement of seismic wave-propagation models in the past decade large three-dimensional simulations of earthquake ground motion have become possible. The resulting datasets from these simulations are multivariate, temporal and multi-terabyte in size. Past visual representations of results from seismic studies have been largely confined to static two-dimensional maps. New visual representations provide scientists with alternate ways of viewing...
