Most ocean acidification (OA) experimental systems rely on pH as an indirect way to control CO2. However, accurate pH measurements are difficult to obtain and shifts in temperature and/or salinity alter the relationship between pH and pCO2. Here we describe a system in which the target pCO2 is controlled via direct analysis of pCO2 in seawater. This direct… (More)
Results of the first stage of the LaserCAD III software package development are presented. The main subjects of LaserCAD III are the dynamics, modulation and power versus behaviour of wide kinds of semiconductor lasers.
