Human inputs of nutrients to coastal waters can lead to the excessive production of algae, a process known as eutrophication. Microbial consumption of this organic matter lowers oxygen levels in the water 1‐3 . In addition, the carbon dioxide produ

The performance of a polymeric membrane-based pH microelectrode and a new pCO2 microelectrode in marine sediments is evaluated for the purpose of collecting fine-scale and undisturbed porewater profiles of carbon dioxide parameters. Both microelectro

pH polymeric membrane microelectrodes based on neutral carriers have been developed for sediment and bio-mat applications. The pH microelectrodes have a tip diameter of 10-40 mm and contain poly(vinyl chloride) (PVC) or carboxylated PVC in its membra

The classic Severinghaus pCO2 microelectrodes have been greatly improved. The drift is reduced from ∼10 to 0.4 mV/h, and the lifetime has been extended from hours or days to one month. The detection limit has been lowered to 200 μatm, and the t98

The transfer of proton, alkali, and alkaline earth metal ions across the water/nitrobenzene interface, facilitated by a synthetic neutral dicarboxamide ionophore in the nitrobenzene phase was investigated using cyclic voltammetry. The ionophore-facil

A simple non-linear regression method for ion-selective electrodes (ISEs) was developed. It can replace Newton's iterative method which has divergence problems. The convergence interval of Newton's iterative method for ISEs was also studied and was d
