Biotic response of Tethyan bathyal ostracodes through the Eocene-Oligocene Transition from the Massignano Composite Stratotype Section (east central Italy) - The Eocene-Oligocene Transition (EOT) is marked by a double-stepped ~1.3‰ positive excursion in d18O over an ~300 kyr interval (i.e., Oi-1; Miller et al., 1991; Zachos et al., 1996; Coxall et al., 2005) and a deepening of the calcium compensation depth (CCD) interpreted to represent marked Antarctic glaciation and global...

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...

Pterygoneurum lamellatum with Crossidioid photosynthetic enations

submitted by: rzander

Pterygoneurum lamellatum is a western and High Arctic moss in North America that has two kinds of photosynthetic enations on the adaxial (ventral) surface of the costa (midrib), the usual lamellae of Pterygoneurum and in this particular specimen from Alaska the (short) filaments of Crossidium.

Visualizing the ground motions of the 1906 San Francisco earthquake

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...
