MelbourneLow oxygen somewhere in the river 90% of the time.
A Frontiers in Marine Science study finds oxygen-starved sediment releases phosphorus, feeding blooms that drain oxygen.
Muck deposits drain bottom oxygen up to 500 metres away, killing the bottom dwellers that keep phosphorus buried.
Standard monitors, which sample at the surface and mid-depth, miss it: bottom oxygen ran 10% to 15% lower.
Florida Tech’s Austin Fox will next quantify hypoxia’s effects in the Indian River Lagoon and its tributaries.
