Short summary

The shell of the California mussel contains alternating dark and light calcium carbonate increments that record whether the shell was growing normally under optimal conditions (light) or slowly under sub-optimal conditions (dark). However, the timing and specific environmental controls of growth band formation have not been tested. We investigated these controls and found links between stable seawater temperatures and light bands and highly variable or extreme temperatures and dark bands.
