The note above stating periods of the data are MTL is misleading. Sections of the original data were MTL. However, Pub. Sci. 5 states “For these periods a shallow water correction has been added to the mean heights of high and low water in order to give a mean height of sea-level comparable with those otherwise calculated for other periods.” Thus, a correction to MSL has already been applied.
