Blood Falls Mystery Solved: Rust-Colored Water Traces Hidden Subglacial Brine Under Taylor Glacier

Scientists have linked Antarctica’s Blood Falls red outflow to episodic subglacial brine drainage beneath Taylor Glacier, showing the rust color marks rapid pressure changes and hidden water movement under the ice, a process that briefly slows glacier flow and disturbs the adjacent lake’s stratification, revealing a millennia‑old brine system with implications for monitoring subglacial hydrology amid warming.
