Potential seasonal calibration for palaeoenvironmental reconstruction using skeletal microstructures and strontium measurements from the cold-water coral Lophelia pertusa
Lophelia pertusa is a colonial cold-water coral species with a wide spatial distribution in recent marine waters. Analysing the chemistry of its skeleton allows reconstruction of environmental parameter variations. While numerous studies have attempted to interpret such analyses, little information...

Lophelia pertusa is a colonial cold-water coral species with a wide spatial distribution in recent marine waters.

This study introduces newly recognized microstructures in the coral wall following growth along the radial axis. The thicknesses of these ‘micro-layers’ are correlated with strontium concentrations and can be used to estimate seasonal growth rates of single polyps from the colony. We propose that each of these micro-layers represents a period of 1 month of mineralization and can locate two decreasing periods in growth rate during a year: one caused by limited food availability during winter months and one in autumn linked to gametogenesis.
