Now, the flooded depths of an abandoned iron mine in southwestern Wisconsin have yielded yet another novelty: microbes that produce nanometer-scale crystals of extraordinary length. The discovery of the willowy microscopic crystals may open a broad new window to human under...Envisat fishes up facts behind Chilean giant squid invasion

... find more." As with all dragonfish, which live at depths ranging from about 600 to 3,000 feet, the new species has menacing teeth, and a mouth that can jut out to engulf prey as wide as it is. They also have small organs along their bellies that produce light, or bioluminescence, and that may serve as camo...Better techniques needed to predict earthquake hazards, UC study finds
...ents. They took and tested soil samples at various depths and simulated hundreds of possible earthquake scenarios based on such variables as where a rupture might occur on the fault, the path it might travel, and how fast it might move.

Plumbing the depths of the San Andreas Fault A set of deep seismic monitors that stretches for more than 1,200 meters [3,900feet] within the San Andreas Fault can likely provide unique information about thevolatile fault system and allow unprecedented monitoring for ear...Two-month study of life in mid-Atlantic yields trove of species, new insights & questions
Exploring life in the mid-Atlantic at various depths down to 4 km (2.5 miles), 60 scientists from 13 countries on a two-month expedition have surfaced a wealth of new information and insights, stunning images and marine life specimens, several thought to be species never before known to science.

In the 2002 event, water at depths of 30-50 meters, within a mile or two of the shoreline, had dissolved oxygen levels in the range of 0.5 to 1 milliliters per liter whereas a normal reading would be about four times that high. Any dissolved oxygen level below 1.4 milliliters per lit...Plumbing trees' plumbing reveals their engineering skill

Deep-sea ecosystems (at depths of >1000 m) comprise more than 60% of the Earth surface, and are the main reservoirs of global biodiversity. Climate changes are expected to induce significant modifications in biodiversity on the global scale, yet little is known on the impact o...Story tips from the Department of Energy's Oak Ridge National Laboratory, September 2004
