Abstract

The pace of sclerochronological research has dramatically accelerated over the past two decades, culminating in an increasingly global network of absolutely dated, well-replicated archives from the calcified structures of bivalves, fish, and corals. Central to this approach is the dendrochronology technique of crossdating through which the correct calendar year of formation is identified for each increment. These crossdated marine records provide uninterrupted multi-decadal to millennial chronologies that can be readily integrated with one another as well as observational physical or biological records. As such, the discipline is positioned for unprecedented synthesis across spatial scales, trophic levels, habitats, and functional types to establish climate-biology relationships, test hypotheses of ecosystem functioning, conduct multi-proxy reconstructions, and provide constraints for numerical climate models. Combining these marine records with tree-ring chronologies will quantify ocean-atmosphere interactions and linkages across marine and terrestrial ecosystems with relevance to natural resources management and climate reconstruction.
