  • Coastal Evolution, Geomorphic Processes and Sedimentary Records in the Anthropocene

    Gomez Christopher , Hart E. Deirdre , Wassmer Patrick , Imai Kenta , Matsui Hiroki , Shimizu Mariko

    … Using three island nations characterized by different stages and styles of coastal development – New Zealand, Japan, and Indonesia - we investigate the role of anthropogenic activity in coastal evolution, geomorphology and sediment records. … In light of these multi-scale and multi-process effects, we argue that the Anthropocene is clearly distinguishable from the Holocene in coastal environments due to the significantly stronger signatures of human influence that characterise the former time period. …
