  • How significant is submarine groundwater discharge and its associated dissolved inorganic carbon in a river-dominated shelf system? 

    Liu, Q.; Dai, Minhan; Chen, W.; Huh, C.-A.; Wang, Guihua; Li, Q.; Charette, Matthew A. (Copernicus Publications on behalf of the European Geosciences Union, 2012-05-22)
    In order to assess the role of submarine groundwater discharge (SGD) and its impact on the carbonate system on the northern South China Sea (NSCS) shelf, we measured seawater concentrations of four radium isotopes ...
  • An improvement in the small-volume technique for determining thorium-234 in seawater 

    Cai, Pinghe; Dai, Minhan; Lv, Dongwei; Chen, Weifang (2005-06-09)
    The recently developed 2‐5 L small‐volume MnO2 coprecipitation method for determining 234Th in seawater has provided a new way to substantially increase, both temporally and spatially, the sampling resolution of 234Th ...
  • Intercalibration studies of short-lived thorium-234 in the water column and marine particles 

    Maiti, Kanchan; Buesseler, Ken O.; Pike, Steven M.; Benitez-Nelson, Claudia R.; Cai, Pinghe; Chen, Weifang; Cochran, Kirk; Dai, Minhan; Dehairs, Frank; Gasser, Beat; Kelly, Roger P.; Masque, Pere; Miller, Lisa A.; Miquel, Juan Carlos; Moran, S. Bradley; Morris, Paul J.; Peine, Florian; Planchon, Frederic; Renfro, Alisha A.; Rutgers van der Loeff, Michiel M.; Santschi, Peter H.; Turnewitsch, Robert; Waples, James T.; Xu, Chen (Association for the Sciences of Limnology and Oceanography, 2012-09)
    Intercomparision of 234Th measurements in both water and particulate samples was carried out between 15 laboratories worldwide, as a part of GEOTRACES inter-calibration program. Particulate samples from four different ...
  • Plutonium in groundwater at the 100K-Area of the U.S. DOE Hanford Site 

    Dai, Minhan; Buesseler, Ken O.; Pike, Steven M. (2004-01-27)
    We examined the concentration, size distribution, redox state and isotopic composition of plutonium (Pu) in groundwater at the 100K-Area at the US Department of Energy’s (DOE) Hanford Site. Total concentrations of Pu ...
  • A review of present techniques and methodological advances in analyzing Th-234 in aquatic systems 

    Rutgers van der Loeff, Michiel M.; Sarin, Manmohan M.; Baskaran, Mark; Benitez-Nelson, Claudia R.; Buesseler, Ken O.; Charette, Matthew A.; Dai, Minhan; Gustafsson, Orjan; Masque, Pere; Morris, Paul J.; Orlandini, Kent; Rodriguez y Baena, Alessia; Savoye, Nicolas; Schmidt, Sabine; Turnewitsch, Robert; Voge, Ingrid; Waples, James T. (2005-10-10)
    The short-lived thorium isotope 234Th (half-life 24.1 days) has been used as a tracer for a variety of transport processes in aquatic systems. Its use as a tracer of oceanic export via sinking particles has stimulated a ...
