Why Blood Falls in Antarctica Flows Bright Red
News Context
At a glance
- A bright red saltwater waterfall spills from the Taylor Glacier in Antarctica, a striking visual anomaly fueled by a subglacial brine reservoir rich in iron.
- Instead, the brine seeps through cracks in the glacier, creating a slow, steady ooze that spreads across the stark white surface of the Taylor Glacier.
- Beneath the ice lies a trapped reservoir of brine, sealed away for an extended period.

The Chemistry of Oxidation
It is not a torrent. Instead, the brine seeps through cracks in the glacier, creating a slow, steady ooze that spreads across the stark white surface of the Taylor Glacier.
A Frozen Brine Reservoir
Beneath the ice lies a trapped reservoir of brine, sealed away for an extended period. This water is extremely salty.

The Timeline of Isolation
The precise age of the reservoir is still a matter of scientific debate. While it is established that the brine has been sealed for a significant era, researchers continue to argue over the exact timeline of when the water first became trapped beneath the ice.
