Scientists used this cross section of bamboo coral, sampled from Davidson Seamount, for lead-210 dating. The series of holes followed circular patterns that could be seen in the growth structure. Age was determined based on the decay of lead-210, from the edge of the cross section to near the center. Image courtesy of A. Andrews/MLML.
