In recent years\, mass loss in southeast Greenland has contributed to more than half of the total mass loss for the entire ice sheet. A significant contributor to southeast GrIS mass loss is Helheim Glacier\, a large marine-terminating outlet glacier with a drainage area >50\,000 km2 and ice speeds >7 km/yr. The altimetry record shows that Helheim Glacier has experienced a complex elevation history (Fig. 1). While the initial thinning phase suggests a dynamic response to changes from calving front retreat\, the cause of the abrupt termination of thinning in 2005\, and subsequent thickening and oscillatory behavior is not known. To better understand this behavior\, and the physical processes responsible\, highly accurate elevation records are required at glacier-scale (>10 km2). Here we reconstruct the 1981 – 2016 elevation history of Helheim Glacier by employing a novel change detection method that improves the vertical accuracy of Digital Elevation Models using laser altimetry time series. Our elevation record shows the surface of the glacier is responding to the disturbance from sustained calving front retreat during 1998 – 2005 via dynamic thinning diffusing upglacier from the calving front (i.e.\, thinning decreases in magnitude with increasing distance from where the glacier meets the ocean)\, and that this diffusion process is controlling the glacier’s overall behavior. We also identify a series of perturbations unrelated to changes occurring at the calving front. The perturbations materialized in 2005\, 2007\, 2011\, 2013\, 2015 and 2016\, expressed as elevation changes >20 m over small areas (<5 km2) coincident with significant bedrock gradients (slopes >10 degrees). This process occurs in topographically confined regions of both fast-flowing tributaries and the main trunk\, and appears to be controlling the recent oscillatory behavior. We find that the oscillatory elevation behavior is due to changes taking place in the subglacial environment (i.e.\, at the ice-bedrock interface)\, either due to changes in basal lubrication\, or the filling & draining of subglacial lakes. This is the first study to capture surface changes from subglacial water routing at a fast-flowing Greenland outlet glacier.
