Ocean Acidification: The Other CO2 Problem

Ocean acidification is a predictable consequence of rising atmospheric CO 2 and does not suffer from uncertainties associated with climate change forecasts. Absorption of anthropogenic CO 2, reduced pH, and lower calcium carbonate (CaCO 3) saturation in surface waters, where the bulk

thus the activity (a), are equal to one (e.g., Ci = γi = ai = 1), and thus the log terms are equal to zero. Then µi = µi°(T,P). The reference state is the solution limit where Ci = ai and thus γi = 1. The choice of reference states determined the value of the activity coefficient, γi. The differences in the activity scales show up as ...

Spatial & Temporal Coherence - NTUA

Prof. Elias N. Glytsis, School of ECE, NTUA 3 Coherence is a measure of the correlation between the phases measured at different (temporal and spatial) points on a wave.

Correlation in Random Variables

Autocorrelation Function The autocorrelation function is very similar to the covariance func-tion. It is defined as R(X,Y)=E[XY]=cov(X,Y)+E[X]E[Y] It retains the mean values in the calculation of the value. The random variables are orthogonal if R(X,Y)=0. Lecture 11 5
