Spline smoothed MS signal from Late Devonian condensed sections in Morroco (from Ellwood et al., 1999) compared to data from western Alberta. Morrocan sections are very thin condensed intervals that were measured at 5 cm intervals. Outcrop data, from much thicker sections, were sampled at 0.5 m intervals. Despite the difference in lithofacies and extreme distance, major MS events constrained by biostratigraphy can be correlated.
