Cross-section
of a coral microatoll from Bai island. The x-rayed thin slab
reveals a clear record of annual growth bands expanding radially
outward (from left to right) at about a cm per year. The Highest
Level of Survival (HLS) of the coral during the past 35 years is
recorded in the topography of the coral's upper surface. The
arrows track the rise of sea level in the 1960s and its subsequent
fall.![]() |
