Using halogens (Cl, Br, I) to understand the hydrogeochemical evolution of drought-derived saline porewater beneath a prairie wetland

Autor: Martin B. Goldhaber, Donald O. Rosenberry, Zunli Lu, Zeno F. Levy, David M. Mushet, Xiaoli Zhou, Laura K. Lautz, Christopher T. Mills, Donald I. Siegel

Numerous closed-basin prairie wetlands throughout the Prairie Pothole Region (PPR) of North America maintain moderate surface pond salinities (total dissolved solids [TDS] from 1 to 10 g L− 1) under semiarid climate by accumulation of gypsum and sa

Acetoclastic Methanosaeta are dominant methanogens in organic-rich Antarctic marine sediments

Autor: Robert F. Dias, Christopher T. Mills, Kevin W. Mandernack, Robert B. Dunbar, Florence Schubotz, Stephanie A. Carr, Roger E. Summons

Publikováno v: The ISME Journal. 12:330-342

Despite accounting for the majority of sedimentary methane, the physiology and relative abundance of subsurface methanogens remain poorly understood. We combined intact polar lipid and metagenome techniques to better constrain the presence and functi

Abundant carbon substrates drive extremely high sulfate reduction rates and methane fluxes in Prairie Pothole Wetlands

Autor: Matthew J. Solensky, Brian A. Tangen, David W. Hoyt, Raymond G. Finocchiaro, Sheel Bansal, Brandon C. McAdams, Christopher T. Mills, Yu-Ping Chin, Michael D. Johnston, Garrett J. Smith, Malak M. Tfaily, Michael J. Wilkins, Paula Dalcin Martins

Inland waters are increasingly recognized as critical sites of methane emissions to the atmosphere, but the biogeochemical reactions driving such fluxes are less well understood. The Prairie Pothole Region (PPR) of North America is one of the largest

Controls on the Geochemical Evolution of Prairie Pothole Region Lakes and Wetlands Over Decadal Time Scales

Autor: Blaine B. McCleskey, Martin B. Goldhaber, Christopher T. Mills, Jennifer Rover, David M. Mushet

Publikováno v: Wetlands. 36:255-272

One hundred sixty-seven Prairie Pothole lakes, ponds and wetlands (largely lakes) previously analyzed chemically during the late 1960’s and early to mid-1970’s were resampled and reanalyzed in 2011–2012. The two sampling periods differed climat

The use of amino acid indices for assessing organic matter quality and microbial abundance in deep-sea Antarctic sediments of IODP Expedition 318

Autor: Christopher T. Mills, Stephanie A. Carr, Kevin W. Mandernack

Publikováno v: Marine Chemistry. 186:72-82

The Adelie Basin, located offshore of the Wilkes Land margin, experiences unusually high sedimentation rates (~ 2 cm yr− 1 ) for the Antarctic coast. This study sought to compare depthwise changes in organic matter (OM) quantity and quality with ch

Changes in Pond Water Levels and Surface Extent Due to Climate Variability Alter Solute Sources to Closed-Basin Prairie-Pothole Wetland Ponds, 1979 to 2012

Autor: James W. LaBaugh, Martin B. Goldhaber, Donald O. Rosenberry, Ned H. Euliss, Christopher T. Mills, David M. Mushet, Richard D. Nelson

Publikováno v: Wetlands. 36:343-355

Wetter conditions beginning in 1993 resulted in marked changes in water levels and surface extent of prairie-pothole region wetland ponds, including closed-basin wetlands in the Cottonwood Lake area of North Dakota, U.S.A. Pond water levels after 199

Using stream-side groundwater discharge for geochemical exploration in mountainous terrain

Autor: Christopher T. Mills, Jean M. Morrison, Andrew H. Manning, Richard B. Wanty

Publikováno v: Journal of Geochemical Exploration. 209:106415

Groundwater chemistry has been predominantly used in geochemical exploration studies to identify mineralized targets concealed under transported cover in areas with gentle topography. Another potentially valuable application that has received little
