Title: Response to the comment “Uranyl-chloride speciation and uranium transport in hydrothermal brines: Comment on Migdisov et al. (2018)” by Dargent et al.

Abstract

We welcome the comments provided by Dargent et al. (2018) and appreciate the effort they have made to evaluate our recently reported data on the stability of uranyl(VI) chloride complexes as function of temperature (Migdisov et al., 2018). We also appreciate the opportunity provided by the editor to clarify issues in our paper that were not clearly articulated or in error.

A spectroscopic study of uranyl speciation in chloride-bearing solutions at temperatures up to 250 °C

Journal Article Migdisov, A. A. ; Boukhalfa, H. ; Timofeev, A. ; ... - Geochimica et Cosmochimica Acta

The speciation of U in NaCl-bearing solutions at temperatures up to 250 °C and concentrations of NaCl up to 1.5 m has been investigated using an in situ spectroscopic technique. The recorded spectra permit us to identify the species present in the solutions as UO₂²⁺, UO₂Cl⁺, and UO₂Cl₂°. UO₂Cl₃^- is also likely present at high temperatures and NaCl concentrations, but concentrations of this species are insufficient for derivation of the formation constants. No evidence was found for species of higher ligand (Cl-) number. Thermodynamic stability constants derived for these species show fair agreement with published data for 25 °C, butmore »« less

Response to Comment on “Iodine-129 and Iodine-127 Speciation in Groundwater at Hanford Site, U.S. Iodate Incorporation into Calcite”

Journal Article Zhang, Saijin ; Xu, Chen ; Creeley, Danielle ; ... - Environmental Science and Technology

In his comment on our paper “Iodine-129 and Iodine-127 Speciation in Groundwater at Hanford Site, U.S.: Iodate Incorporation into Calcite”, Lu specified three concerns for Zhang et al’s study,1 including (1) precipitation mechanism (degassing vs freezing), (2) analytical methods, and (3) mass balance control. In response, comparative and comprehensive discussions on the precipitation mechanisms and iodine incorporation can be found in the paper, as well as below. This includes additional experiments of iodine distribution and speciation in calcite precipitates. In addition, the measurements of total iodine in soils/sediment were clarified below as well. The calculations on mass balance in thismore »« less

Journal Article Kollet, S J ; Zlotnik, V A - Journal of Hydrology

We thank H. Lough for her interest in our data set and the attempt to re-analyze our results (Kollet and Zlotnik, 2003) using the recent model by Hunt (2003). We welcome others to share our unique data set of the pumping test from the Prairie Creek site, Nebraska, USA. Nevertheless we believe that this particular attempt failed, because H. Lough selected a wrong model of semi-confined aquifer conditions for the interpretation of the pumping test data, which was collected in an unconfined aquifer. H. Lough based her selection on the three distinct drawdown segments observed during the test. It ismore »« less

Reply to Quaas et al.: Can satellites be used to estimate indirect climate forcing by aerosols?

Journal Article Penner, J E ; Zhou, Cheng ; Xu, Li ; ... - Proceedings of the National Academy of Sciences of the United States of America, 108(46):E1100-E1101

We welcome the comments by Quaas et al. (1). In our paper (2), we used a model to show that the methods used to estimate indirect aerosol forcing using satellite data, especially those based on relating the slope of present-day (PD) drop number (Nc) to aerosol optical depth (AOD), underestimate the forcing calculated when both PD and preindustrial (PI) data are available.
