Bivalve Molluscs: Barometers of Climate Change in Arctic Marine Systems
Bivalve mollusks store a complete history of their life in the growth lines in their valves. Through sclerochronology, in combination with isotope signatures, it is possible to reconstruct both post-recruitment growth history at the individual level and commensurate environmental records of temperat...
