This substance accelerates movement at the marginal zone according to the Zwally effect. Radioactive dating of coral samples allows for analysis of the 1A pulse of this substance. The presence of this substance at the basal layer allows movement via sliding and subsole deformation. Giant gravel bars and megaripples may be evidence for (*) jÃ¶kulhlaups ["YO-kul-hlops"], which are huge outbursts of this substance. This is the main product of ablation and is not caused by sublimation or calving.  This substance may be created by high pressures and geothermal energy under glaciers, and runoff of large amounts of it may be evidence for global warming. For 10 points, name this substance which is the result of glacial melting.
