Key points
- Blue Lake is on North Stradbroke Island, off the coast of Brisbane
- Scientists found lake's chemistry has changed very little over 7,500 years
- Study looked at fossil pollen and fossil algae as proxies for environmental change
- Lake drains into a swamp and is refreshed by an aquifer, so does not evaporate or become more saline
