The project « Austre Lovénbreen: water » aims at investigating, at long term, the hydrological and hydrogeological of Austre Lovénbreen (AL) watershed on the west coast of Spitsbergen (Ny-Ålesund region) in the High Arctic (79 ° N, 12 ° E). The AL glacier watershed gets a rare feature in the Arctic: he has two well-defined and time-invariant outlets allowing for complete hydrological monitoring of long-term flows: the Goule river which concentrates most of the flow and the Devil, a secondary outlet. The watershed of this glacier has been equipped since 2008 for the hydrological monitoring of water/solutes flows as well as that of the main components of water balance (meteorological station for monitoring of precipitation and air temperature, hydrological stations for monitoring flows at outlets and main physico-chemical characteristics of water, piezometers (5) for monitoring groundwater dynamics, thermal sensors for monitoring the active layer and the permafrost top geometry. This project is associated with the « Austre Lovénbreen: snow and ice » project focused on the study of the snow and ice dynamics useful for the water balance. The results obtained in the framework of previous projects supported by the IPEV showed, at the annual scale, a trend between the increasing air temperature and the increase of freshwater flow. This project aims to carry out a long-term monitoring of the hydrology of the AL watershed in order to confirm or invalidate observed trends between discharge, main climate parameters, hydrological response of permafrost in an environment where air temperature increases (+ 0.56 ° C / decade) and precipitation amount also increases significantly (+22 mm precipitation / decade). This hydrological observatory project, included in OZCAR French RI could constitute a contribution to European research infrastructure, Svalbard Integrated Arctic Earth Observing System (ESFRI SIOS).
