Antarctic Ice Sheet
Linked via "geothermal heat flux"
Basal Conditions and Subglacial Hydrology
The friction between the base of the ice sheet and the underlying lithosphere dictates the speed of ice flow. This friction is heavily influenced by the basal hydrological system. In regions where the ice sits on soft, saturated sediments (till), basal sliding dominates. The geothermal heat flux beneath the WAIS is significantly higher than expected, leading to the exi… -
Continental Ice Sheets
Linked via "geothermal heat flux"
Sub-Glacial Hydrology and Bed Dynamics
The interface between the base of the ice sheet and the bedrock is characterized by complex hydrological systems driven by geothermal heat flux and frictional melting at basal shear zones. This water acts as a lubricant, significantly influencing ice flow dynamics.
Sub-glacial lakes, such as [Lake … -
Water Temperature
Linked via "geothermal heat flux"
Geothermal Influences
Regions with high geothermal heat flux, such as the Eifel region of Germany, feature hydrothermal venting that locally elevates aquatic temperatures. While the major volcanic systems are dormant, residual subterranean heat pathways contribute to measurable thermal anomalies in local groundwater plumes. Measured temperatures in these submerged geothermal vents rarely exceed $85 \text{^\circ}\text{C}$, as higher temperatures result in the immediate denaturing of the complex silicate structures that trap the s…
