Measurement of the apparent dissociation constants of carbonic acid in seawater at atmospheric pressure1

TLDR
The apparent dissociation constants of carbonic acid in seawater were determined as functions of temperature (2-35°C) and salinity (19-43%) at atmospheric pressure by measurement of K'1 and the product K', K' as discussed by the authors.
Abstract
The apparent dissociation constants of carbonic acid in seawater were determined as functions of temperature (2-35°C) and salinity ( 19-43%) at atmospheric pressure by measurement of K’1 and the product K’, K’,. At 35sa salinity and 25°C the measured values were pE1 = 6.600 and pK’2 = 9.115; at 35% and 2°C the measured values were pK’1 = 6.177 and pKPz = 9.431.

A comparison of the equilibrium constants for the dissociation of carbonic acid in seawater media

TL;DR: In this paper, the published experimental data of Hansson and Mehrbach et al. have been critically compared after adjustment to a common pH scale based upon total hydrogen ion concentration, and the results have been pooled to yield reliable equations that can be used to estimate pK1∗and pK2∗ for seawater media a salinities from 0 to 40 and at temperatures from 2 to 35°C.

A global ocean carbon climatology: Results from Global Data Analysis Project (GLODAP)

TL;DR: The Global Ocean Data Analysis Project (GLODAP) as mentioned in this paper uses ocean sampling data from the World Ocean Circulation Experiment (WOCE), the Joint Global Ocean Flux Study (JGOFS), and the Ocean Atmosphere Carbon Exchange Study (OACES) to produce objectively gridded property maps at a 1° resolution on 33 depth surfaces chosen to match existing climatologies for temperature, salinity, oxygen, and nutrients.

Determination of the equivalence point in potentiometric titrations. Part II

Gunnar Gran
- 01 Jan 1952 - 
TL;DR: In this article, the potential -volume curve obtained during potentiometric titrations shows only a small potential change at the end-point, and it has been customary to plot a deltaE/deltaV-volume curve and to take the peak of this curve as the equivalent point.
