the total alkalinity–pH equation pathway to robust
2014/12/12
The total alkalinity–pH equation, which relates total alkalinity and pH for a given set of total concentrations
of the acid–base systems that contribute to total alkalinity
in a given water sample, ...
Pore-water exchange driven by tidal pumping causes alkalinity export in two intertidal inlets
intertidal inlets idal pumping
2014/10/16
Carbon (C) and alkalinity export from two adjacent intertidal inlets with different terrestrial inputs was
investigated. One inlet receives a small creek from an agriculturally dominated catchment, l...
Potentiometric open-cell titration for seawater alkalinity considering temperature dependence of titrant density and Nernst response of pH electrode
Balkalinity open-cell titration potentiometric method HCl density Nernst response

The total alkalinity (AT) of seawater is one of the parameters required to characterize carbonate systems, which are
essential for studying the greenhouse effects of carbon dioxide (CO2) on the Earth...
Role of dust alkalinity in acid mobilization of iron
dust alkalinity acid mobilization of iron
2010/10/11
Atmospheric processing of mineral aerosols by acid gases (e.g., SO2, HNO3, N2O5, and HCl) may play a key role in the transformation of insoluble iron (Fe in the oxidized or ferric (III) form) to solub...
Introducing the bromide/alkalinity ratio for a follow-up discussion on "Precipitation of salts in freezing seawater and ozone depletion events: a status report", by Morin et al., published in Atmos. Chem. Phys., 8, 7317–7324, 2008
the bromide/alkalinity ratio freezing seawater ozone depletion events salts
2010/8/25
Sander et al. (2006) proposed that CaCO3 precipitation can be an important factor in triggering tropospheric ozone depletion events. Recently, Morin et al. (2008b) presented calculations with the FREZ...
Open-cell Titration of Seawater for Alkalinity Measurements by Colorimetry Using Bromophenol Blue Combined with a Non-linear Least-squares Method
Seawater for Alkalinity Measurements Colorimetry Using Bromophenol Blue Combined Non-linear Least-squares Method
2010/9/13
The open-cell titration of seawater was studied for alkalinity measurements by colorimetry. 1) The colorimetric pH of free hydrogen ion concentration, pHF(ind), was calculated from the ratio of the ab...
Integrated Modelling of Runoff,Alkalinity,and pH on a Daily Basis
Integrated Modelling Runoff Alkalinity Daily Basis
2009/10/27
Based on the experience from runoff and groundwater recharge simulation a
model system has been developed for terrestrial, hydrochemical, and hydrological
simulations. The system emphasizes the role...

CO2 perturbation experiments similarities inorganic carbon total alkalinity manipulations
2010/1/21
Increasing atmospheric carbon dioxide (CO2) through human activities and invasion of anthropogenic CO2 into the surface ocean alters the seawater carbonate chemistry, increasing CO2 and bicarbonate (H...
Spatial and temporal variation in pH, alkalinity and conductivity in surface runoff and groundwater for the Upper River Severn catchment
pH surface runoff alkalinity conductivity Upper River Severn catchment
2009/6/8
Measurements of pH, alkalinity and electrical conductivity are used to examine the extent of the spatial and temporal variation in stream and ground water chemistry for the Upper Severn catchment, Pl...
Long-term and seasonal variations in CO2: linkages to catchment alkalinity generation
CO2 alkalinity acidification
2009/3/23
As atmospheric emissions of S have declined in the Northern Hemisphere, there has been an expectation of increased pH and alkalinity in streams believed to have been acidified by excess S and N.
Enhanced ocean carbon storage from anaerobic alkalinity generation in coastal sediments
ocean carbon storage anaerobic alkalinity generation coastal sediments
2010/1/19
The coastal ocean is a crucial link between land, the open ocean and the atmosphere. The shallowness of the water column permits close interactions between the sedimentary, aquatic and atmospheric com...
