Iceland is located where the asthenosperic flow under the the NE Atlantic plate boundary interacts and mixes with a deep-seated mantle plume. The buoyancy of the Iceland plume leads to dynamic uplift of the Iceland plateau, and high volcanic productivity over the plume produces a thick crust. (Fig.1). The Greenland-Færöy ridge represents the Icland plume track through the history of the NE Atla...

[1] TheMoscoviense Basin, on the northern portion of the lunar farside, displays topography with a partial peak ring, in addition to rings that are offset to the southeast. These rings do not follow the typical concentric ring spacing that is recognized with other basins, suggesting that they may have formed as a result of an oblique impact or perhaps multiple impacts. In addition to the unusua...

Several lines of evidence from analysis of impact craters and other morphological features on Ida indicate the asteroid surface is covered with a thin layer of regolith that probably grades downward into less well-sorted rubble/megaregolith. This transition with depth is too gradational or occurs too close to the surface to be expressed in crater morphology at available resolution. Gravitationa...

We begin this paper with a consideration of the significance of a historical perspective in presentations of evidence-based practice in the nursing and medical literature. We suggest that whereas writers often produce coherent historical narratives as justification for particular views of the nature of EBP, an examination of its origins reveals no such signs of historical development or progres...

We’ve seen that evaluating an idea in science is not always a matter of one key experiment and a definitive result. Scientists often consider multiple ideas at once and test those ideas in many different ways. This process generates multiple lines of evidence relevant to each idea. For example, two competing ideas about coral atoll formation (island subsidence vs. formation on debris-topped und...

Reconnaissance geologic mapping of south-central Oregon is being done by the U. S. Geological Survey, in cooperation with the State of Oregon Department of Geology and Mineral Industries, as part of a larger program to prepare a geologic map of the eastern half of the state. Current work in south-central Oregon is limited geographically to the eastern half
