Caribbean coral tracks Atlantic Multidecadal Oscillation and past hurricane activity

Cayo Sal, Los Roques Archipelago, Venezuela

Counting annual density bands provided an age model for these samples. The exact position of the annual banding over core breaks was reconstructed by stacking the coral slabs together into round core sections with spacers representing the material lost in cutting the cores and with a life-size copy of the X-radiograph taped to the microdrilled slab. The two pieces of core were joined by aligning the corallites of each section, and the X-radiographs on both sides of the core break were marked exactly where they met. Once the breaks were aligned, we used the X-radiographs to count density bands multiple times. We estimate an error of i¿½1 year at the bottom of the core.
