Researchers at the University of Adelaide have found that a
lake on an island off the coast of Queensland has been relatively untouched by
changes in climate for the past 7000 years, and has so far also resisted the
impact of humans.
Blue Lake, one of the largest lakes on North Stradbroke
Island, southeast of Brisbane, has been the focus of research examining the
lake's response to environmental change over time.
Researchers studied the lake's water discharge, water
quality and comparisons of historical photos over the past 117 years, as well
as fossil pollen and algae to better understand its history over the past 7500
years.
