Description :
Holocene coastal evolution in New South Wales has been interpreted essentially as the unfolding of the impact of marine transgression. An alternate interpretation presented here challenges the concept of the marine transgression as the primary « forcing function ». It a) attributes early Holocene dune mobilisation to climate rather than the rising sea; b) shows that the sea reached its present level by 7 ka and rose to at last + 2 m until ∼ 1,5 ka; c) links late Holocene activity to local disruption of vegetation rather than to regional episodic storminess; d) demonstrates a fall of 2o C in sea surface temperature after 3 ka that coincides with the onset of barrier erosion; 2) recognises the imprint of at least three tsunamis in the coastal sedimentary record.
