An electron backscatter diffraction study of geesops: a broader view of trilobite vision? [PDF]
The calcite eyes of trilobites have been studied for over 100 years using methods including light microscopy (e.g. Clarke 1889; Campbell 1975; Towe 1973; Clarkson 1979 and Bruton and Haas 2003) and more recently cathodoluminescence (CL) imaging coupled ...

The influence of magnetospheric substorms on SuperDARN radar backscatter [PDF]
The SuperDARN ionospheric radar network is a leading tool for investigating the near-Earth space environment. However, reductions in ionospheric backscatter have been reported during magnetospheric substorms.

Optimizing electron backscatter diffraction of carbonate biominerals—resin type and carbon coating [PDF]
Electron backscatter diffraction (EBSD) is becoming a widely used technique to determine crystallographic orientation in biogenic carbonates. Despite this use, there is little information available on preparation for the analysis of biogenic carbonates ...
