Capturing the transition from marine to land-terminating glacier from the 126-year retreat history of Nordenskioldbreen, Svalbard

Original language description

Svalbard has experienced a dramatic increase in air temperature and glacier retreat since the end of the Little Ice Age. In many cases, this retreat has resulted in glaciers transitioning from being marine-terminating to land-terminating. Nordenskioldbreen is an excellent contemporary example of this transition. A set of historical observations of glacier front positions was used to assess Nordenskioldbreen's retreat rate and we found that the southern portion of the glacier front retreated by similar to 3500 m, since records began in 1896. The general retreat rate corresponds well with the air temperature trend during most of the 20th century. However, the average retreat rate has slowed since the 1990s despite increasing air temperatures. We show that this discrepancy between air temperature and retreat rate marks the transition from marine-terminating towards a land-terminating glacier, as the glacier's bedrock topography started to play an essential role in the glacier margin geometry, ice flow and retreat dynamics.
