Example Sentences

The actual sources and locations of subglacial methane production actually remain somewhat of a mystery, hidden beneath ice masses of all sizes.

From Science Daily

"Subglacial meltwater has been inferred beneath most if not all Antarctic glaciers, including Thwaites, Pine Island, and Totten glaciers," said Pelle.

From Science Daily

"All these glaciers are retreating and contributing to sea-level rise and we are showing that subglacial discharge could be accelerating their retreat. It's urgent that we model these other glaciers so we can get a handle on the magnitude of the effect subglacial discharge is having."

From Science Daily

The model's simulations revealed that adding in subglacial discharge reconciled the melt rates seen at Denman and Scott Glaciers.

From Science Daily

As for why Scott Glacier was melting so much slower than Denman, Pelle said the model showed that "a strong subglacial discharge channel drained across the Denman Glacier grounding line, while a weaker discharge channel drained across the Scott Glacier grounding line."
