(2001)Previous research by our group (e.g., [Chem. Geol. 132 (1996) 25; Geochim. Cosmochim. Acta 64 (2000) 1363]) has shown that an aerobic Pseudomonas mendocina bacterium enhances Fe(hydr)oxide dissolution in order to obtain ...
-
(1999)Experiments describing the extent of dissolution of β-MnOOH(s) suspensions vs. time using measurements of both total dissolved Mn and Mn(III) complex species show that the ligands pyrophosphate (P2O74-), ethyelenediamine ...
-
(1998)In the system Di–Ab–An–H2O, melt inclusions in plagioclase were reproducibly formed in a series of partial dissolution experiments, and the compositional differences from the surrounding matrix melt were evaluated. At 200 ...
-
(1996)Scanning Force Microscopy (SFM) was used to develop a method which can provide quantitative kinetic data of crystal growth and dissolution. Based on observations of single crystal faces in monolayer resolution, morphology ...
-
(1998)This paper reports on our use of scanning force microscopy (SFM) to study calcite dissolution rates. Until now, calculation of rates has been limited to surfaces on which steps retreat at an isotropic velocity. More commonly, ...
-
(2002)Experimentally observed dissolution rates of minerals in an aqueous solution are determined by surface reaction rates, mass transport by molecular diffusion through a diffusion boundary layer (DBL) and the morphology of ...
-
(2004)To help constrain models involving the chemical stability and lifetime of gas clathrate hydrates exposed at the seafloor, dissolution rates of pure methane and carbon-dioxide hydrates were measured directly on the seafloor ...
-
(1986)The dissolution rates of the major upper mantle minerals olivine, orthopyroxene, clinopyroxene, spinel, and garnet have been determined in an alkali basalt melt at superliquidus temperatures and 5, 12, and 30 kb. At low ...
-
(2006)Variability of dissolved Fe2+ and ∑H2S concentrations in porewaters were studied, using cathodic stripping voltammetry (CSV) microelectrodes, in sediments overlain by hypoxic waters in the summer from the southeastern ...
-
(2006)The N, P, and S cycles in pristine forests are assumed to differ from those of anthropogenically impacted areas, but there are only a few studies to support this. Our objective was therefore to assess the controls of N, ...
-
(2006)The circulation of hydrothermal fluid through the upper oceanic crustal reservoir has a large impact on the chemistry of seawater, yet the impact on dissolved organic carbon (DOC) in the ocean has received almost no ...
-
(1996)Fe(III) and Fe(II) organic complexes were determined by spectroscopic methods after sephadex gel fractionation of salt marsh porewaters during June and July 1993. Fe(III), which is a significant anaerobic oxidant for sulfide ...
-
(PANGAEA, 2019-02-26)River water is the main source of dissolved organic carbon (DOC) in the Arctic Ocean. DOC plays and important role in the Arctic carbon cycle and its export from land to sea is expected to increase with accelerated permafrost ...

(2006)Twenty-nine water samples were collected from different river channels of the Pearl River Delta Economic Zone, China. An inductively coupled plasma-mass spectromonitor (ICP-MS) was used to measure concentrations of the ...
-
(1999)New experimental amphibole/melt partition coefficients from a variety of geologically relevant amphibole (pargasite, kaersutite, and K-richterite) and melt compositions obtained under conditions of interest to upper-mantle ...
-
(2002)The paper reports the results of detailed studies (in 1990-1999) of the fumarolic activity at Kudryavyi volcano. The highest temperature of the fumarolic gages of 940degreesC was registered in 1992, after which the gas ...
