1. The ECM profile shows two large peaks at 88 m and 123 m.

2. The preliminary age-depth profile shows ages corresponding to about 1881 and 1805 A.D.

3. The volcanic record of events most likely to have recorded ECM peaks indicate the sources of the two large peaks are Krakatau (1883 A.D.) and Tambora (1815 A.D.).

4. A refined age-depth profile was constructed combining isotopic age dates and the Krakatau and Tambora volcanic events. The ¹⁴C date and 7 volcanic events prior to Tambora were not used in the refined age-depth profile.
