Evidence for a late thermal event of unequilibrated enstatite chondrites: a Rb-Sr study of Qingzhen and Yamato 6901 (EH3) and Khairpur (EL6)
N. Torigoye, M. Shima
1993, Meteoritics (28) 515-527
The Rb-Sr whole rock and internal systematics of two EH3 chondrites, Qingzhen and Yamato 6901, and of one EL6 chondrite, Khairpur, were determined. Sulfides were separated using a stepwise dissolution technique. The mineral species in each fraction were estimated based on the chemical analyses of 12 major elements. The internal...
Digital Elevation Models
Water Resources Division, U.S. Geological Survey
1993, Data Users Guide 5
The Earth Science Information Center (ESIC) distributes digital cartographic/geographic data files produced by the U.S. Geological Survey (USGS) as part of the National Mapping Program. Digital cartographic data files may be grouped into four basic types. The first of these, called a Digital Line Graph (DLG), is the line map...
Complex interactions of multiple aquatic consumers: an experimental mesocosm manipulation
William B. Richardson, Stephen T. Threlkeld
1993, Canadian Journal of Fisheries and Aquatic Sciences (50) 29-42
In 7-m3 outdoor tanks filled with lake water, the presence/absence of omnivorous young-of-the- year Micropterus salmoides), zooplanktivorous Menidia beryllina , and herbivorous larval Hyla chrysocelis was experimentally manipulated. A cross-classified design was used to assess the interactive effects of these vertebrate consumers on the experimental food webs....

All publications and their prices are on a separate price list included with this catalog. This price list will be updated as needed to reflect new...
Digital orthophotos
Water Resources Division, U.S. Geological Survey
1993, Report
A digital orthophoto is a digital image of an aerial photograph with displacements caused by the camera angle and the terrain removed. It, thus, combines the image characteristics of a photograph with the geometric qualities of a map....

The potential response of eolian sands to greenhouse warming and precipitation reduction on the Great Plains of the U.S.A.
D.R. Muhs, P.B. Maat
1993, Journal of Arid Environments (25) 351-361
Sand dunes and sand sheets are extensive on the semi-arid GreatPlains but are at present stabilized by a sparse vegetation cover. Use of a dune mobility index, which incorporates wind strength and the ratio of mean annual precipitation to potential evapotranspiration, shows that under predicted greenhouse climate effects of increased...
