SUMMARY

The discussion centers on the unique phenomenon of Fe2+ brine solution at Taylor Glacier, known as Blood Falls, in Antarctica. It highlights the presence of strong diurnal signals in seismic data that are not linked to cultural or geophysical sources. The challenge presented involves calculating the maximum force or stress exerted by a confined Fe brine solution, influenced solely by Earth Tides, using specific magnetic susceptibility values and volume estimates. Relevant resources include the Blood Falls Wikipedia page and Earth Tides data from the USGS.

PREREQUISITES
  • Understanding of magnetic susceptibility in geophysical contexts
  • Knowledge of Earth Tides and their effects on subglacial environments
  • Basic mechanics and stress analysis principles
  • Familiarity with seismic data interpretation
NEXT STEPS
  • Research the mechanics of confined fluid dynamics in geophysical settings
  • Explore the mathematical modeling of Earth Tides effects on subglacial systems
  • Investigate the properties and behavior of Fe brine solutions in extreme environments
  • Study seismic data analysis techniques relevant to diurnal signal detection
USEFUL FOR

Geophysicists, environmental scientists, and researchers interested in subglacial hydrology and the effects of Earth Tides on geological formations.

Here is a esoteric problem that is totally unique in nature: Taylor Glacier, in the Dry Valleys of Antarctica, hosts site of a Fe2+ brine solution, expressed as a rusty discharge at the terminus. There is strong diurnal signals in seismic data gathered from an array co-located there, not attributable to cultural, or other geophysical inputs.

Challenge: with a median value of magnetic susceptibility for concentrated Fe brine, and assuming volumes on the order of cubic meters (not cubic km, for example), what is the maximum force or stress that a confined solution (subglacially) can exert on it's walls, driven by Earth Tides alone?

It's outside my expertise (mechanics, math mostly) but someone might have a Fermi-type solution.

I did some quick searches and found an interesting article about Taylor Glacier, which is where this brine is located. It's called Blood Falls, and from what I read it appears that this brine has been there for over a million years. This article (http://en.wikipedia.org/wiki/Blood_Falls) might provide some insights into the problem. The Earth Tides Data link provided looks like a valuable resource as well. Good luck!
