Temporal geochemistry data from five springs in the Cement Creek watershed, San Juan County, Colorado
Seasonal geochemical data intended to understand formation of ferricretes and to help understand the ground-water flow system.
Associated data for Water Quality and Sediment Quality in the Albemarle Sound, North Carolina, 2012–14, Appendix 3
These are all the chemical, biological, and physical results collected in 2013 and 2014 for the subject study.
This community serves to document data and analysis collected by researchers within the Upper Midwest Water Science Center whose mission is to collect high-quality hydrologic data and conduct unbiased, scientifically sound studies of water resources within the Great Lakes and Upper Mississippi Basins. We strive to meet the changing needs of those who use our information—from the distribution, availability, and quality of our water resources to topic-oriented research that addresses current hydrological issues.
Trends are identified changes over time in the characteristics of groundwater and (or) surface water. The characteristics analyzed can include descriptions of both quantity and quality. The calculated trends are dependent upon the available data and the methods used to identify trends. (Updated 12/23/2015)
Associated data for Water Quality and Sediment Quality in the Albemarle Sound, North Carolina, 2012–14
This data release contains environmental and quality control results for chemical, biological, and physical sampling of water and bed sediment from Albemarle Sound and associated tributaries between 2012 and 2014 referenced in USGS OFR 2016-1171. Appendix 1 contains all quality control results to characterize the bias and variability of sampling, handling, and analysis of water, phytoplankton, and bed sediment samples. Appendix 2 contains all the chemical, biological, and physical results for water samples collected in July and August of 2012. Appendix 3 contains all the chemical, biological, and physical results for water samples collected from March 2013 to February 2014. Data are included for discrete samples...
Summit crater lake observations, and the location, chemistry, and pH of water samples near Mount Chiginagak volcano, Alaska: 2004-2011
