Table 1 The ensemble averaged June-July-August (JJA) mean discharge (Qsg) magnitude for the Petermann catchment [in m3/s] that is distributed uniformly across the grounding line for present conditions (1995–2014), future conditions (2081–2100, under the RCP 8.5 scenario), a control scenario, and a median scenario

From: Enhanced subglacial discharge amplifies Petermann Ice Shelf melting when ocean thermal forcing saturates
