History Matters Monday, January 22, Implications for New England of the latest analysis on the impact of sea level change on Aboriginal Australia - a note Regular commenter JohnB pointed me to a new paper on historic sea level changes in Australia: Turneya, Sea-level change and demography during the last glacial termination and early Holocene across the Australian continent, Quaternary Science Reviews Volume15 FebruaryPages —, published on line 12 January This third note on understanding the impact of sea level change in Aboriginal New England takes this paper as an entry point for a broader discussion focused on the impact of sea level and associated climatic changes on New England Aboriginal life.

This is an especial problem for their population modelling. The Williams et al Paper Map of Australia by Sean Ulm showing sea-level change and archaeological sites for selected periods between 35, and 8, years ago.
Note the apparently small shifts in Northern NSW relative to some other areas. The on-line abstract of the paper summarises some of the paper in this way: Investigation science writer jobs australia inverell scale, pace and human impacts of post-glacial sea-level change.
Presents continental-scale consensus sea-level curve for Sahul between ka. Populations low, but likely severely disrupted, and led to new configurations.
The abstract of the paper reads: Using comprehensive palaeoenvironmental and archaeological datasets, we report the first quantitative model of the timing, spatial extent and pace of sea-level change in the Sahul region between ka, and explore its effects on hunter-gatherer populations.
Results show that the continental landmass excluding New Guinea increased to 9. Spatially, inundation was highly variable, with greatest impacts across the northern half of Australia, while large parts of the east, south and west coastal margins were relatively unaffected.
Our data support the hypothesis that late Pleistocene coastal populations were low, with use of coastal resources embedded in broad-ranging foraging strategies, and which would have been severely disrupted in some regions and at some time periods by sea-level change outpacing tolerances of mangals and other near-shore ecological communities".
The map is from this paper. Some of their key points can be summarised this way: The potential impacts of these past sea-level changes on Aboriginal populations and societies have long been a subject of speculation by archaeologists and historians.
Archaeologists have long recognised that Aboriginal people would have occupied the now-drowned continental shelves surrounding Australia, but opinions have been divided about the nature of occupation and the significance of sea-level rise.
Most have suggested that the ancient coasts were little-used or underpopulated in the past. Our data show that Aboriginal populations were severely disrupted by sea-level change in many areas. Perhaps surprisingly the initial decrease in sea level prior to the peak of the last ice age resulted in people largely abandoning the coastline, and heading inland, with a number of archaeological sites within the interior becoming established at this time.
With the onset of the massive inundation after the end of the last ice age people evacuated the coasts causing markedly increased population densities across Australia from around 1 person for every square km 20, years ago, to 1 person every square km 10, years ago.
This may have been an important element in the development of the complex geographical and religious landscape that European explorers observed in the 18th and 19th centuries.
Following the stabilisation of the sea level after 8, years ago, we start to see the onset of intensive technological investment and manipulation of the landscape such as fish traps and landscape burning We also see the formation of territories evident by marking of place through rock art that continues to propagate up until the present time.English Teacher Jobs in London Searching for an English teacher job in London?
