Mulgor Logo Long Waves at Charleston 

The figures below show the latest data presented in two different ways. Figure 1A is the raw long-wave record. Figure 2A is the same record, but with the background noise removed to leave only the significant long waves. Figures 2B and C show the individual heights and periods of those waves. Figure 1B is a contour plot showing how the wave height is distributed with time and period.

Figure 1. A. raw long wave record; B. distribution of significant wave height with time and period.

Figure 2. A. long wave record, denoised to remove spurious waves; B. height of each wave; and C. period of each wave.

How were these calculated?
