Scaling up: Fulfilling the promise of X-ray microprobe for biogeochemical research Toner, B. M., S. L., Nicholas, and J. K. Coleman Wasik. 2014. Environmental Chemistry 11, 4-9
Biogeochemists measure and model fluxes of materials among environmental compartments, often considering large spatial-scales within and among ecosystems. However, critical biogeochemical processes occur at fine-spatial scales, and quantifying these processes is a challenge. Recent developments in microprobe X-ray absorption spectroscopy (XAS) data collection and analysis allow for micro-scale observations and quantification of chemical species at the sample-level. These speciation mapping methods create datasets that can be integrated with bulk observations through empirical and theoretical modeling.

SLICE: Sustaining Lakes in a Changing Environment is found on the Department of Natural Resources website which states the purpose of SLICE: To monitor and model Minnesota lake ecosystems for the detection and better understanding of the effects of environmental stressors in order to guide management that sustains fisheries and water resources for future generations.

Development of Flood-Inundation Maps for the Mississippi River in Saint Paul, Minnesota Christiana R. Czuba, James D. Fallon, Corby R. Lewis, and Diane F. Cooper
Digital flood-inundation maps for a 6.3-mile reach of the Mississippi River in Saint Paul, Minnesota, were developed through a multi-agency effort by the U.S. Geological Survey in cooperation with the U.S. Army Corps of Engineers and in collaboration with the National Weather Service. The inundation maps, which can be accessed through the U.S. Geological Survey Flood Inundation Mapping Science Web site at http://water.usgs.gov/osw/flood_inundation/ and the National Weather Service Advanced Hydrologic Prediction Service site at http://water.weather.gov/ahps/inundation.php, depict estimates of the areal extent and depth of flooding corresponding to selected water levels (stages) at the U.S. Geological Survey streamgage at the Mississippi River at Saint Paul (05331000). The National Weather Service forecasted peak-stage information at the streamgage may be used in conjunction with the maps developed in this study to show predicted areas of flood inundation.
