Their claim, however, will remain undersubstantiated until the following issues are clarified. First, Figure 5A of Eriksson and Simpson (2000) shows a peak around 13, which is interpreted as a response to neap-spring-neap cycles, containing both dominant and subordinate flood-tide foreset bundles (p. 833). Removal of subordinate (thinner) foreset bundles from the original data set should lower the number of laminae/cycle to around 6–7. Harmonic analysis of the processed data set (subordinate flood-tide data removed;...
