Alkaline measurements (carbonate alkalinity and total alkalinity) are of great importance in analyses of ocean, marine, lake and river waters, and other samples. Carbonate alkalinity (CA) refers to the cases in which only bicarbonate and carbonate species are considered. Total alkalinity (Alk) ...
HereK0is the solubility constant, andK1/K2is the ratio of the first and second dissociation constants of carbonic acid. When a water mass isolated from the atmosphere (referred to herein as a closed system) is cooled, the ratio,K1/K2, will increase (Fig.1a), and the acid–base equilibriu...

for most of the observations elevated levels of total alkalinity (TA) and pH were observed at the estuary mouth relative to the coastal ocean. This suggests that SDL partly buffers against acidification of adjacent coastal surface waters, although the spatial extent of this buffering is likely smal...
1 compare measured and calculated values for carbonate system parameters Discussion The goal of this study was to assess the validity of carbonic acid dissociation constants (K1⁎, K2⁎) derived for oceanic waters in high-S, low-T sea-ice brine samples. We used sample collection techniques...
The commonly used CO2 constants of Mehrbach et al., (1973) were limited to salinities (19 to 43) and temperatures (2 to 35°C). They cannot be used to study estuarine or fresh waters. The results of these measured pK1* and pK2* values are in good agreement with those determined ...
Modeling of titration data identified three groups of organic charge sites, with mean acid–base dissociation constants (pKa) of 4.2 (± 0.5), 5.9 (± 0.7) and 8.5 (± 0.2). These represented 21% (± 9%), 8% (± 5%), and 71% (± 11%) of titrated organic charge groups...
In addition, environmental factors such as temperature and hydrodynamics can affect the dynamics of a carbonate system in coastal waters [6]. For example, increasing temperature can reduce CO2 solubility in seawater. Meanwhile, temperature can significantly affect the metabolic process of marine organisms...
