The freshwater content of the Arctic Ocean has increased in recent years in response to climate change, but the impact of freshening on coastal ecosystems, such as fjords, is largely unknown. Freshening is important, as the related change in density can weaken vertical mixing and, subsequently, slow or stop the renewal of the fjord bottom water. Analysis of long‐term data (2003–2015) near Young Sound‐Tyrolerfjord, a high Arctic fjord in Northeast Greenland, identified anomalously strong freshening events that are at the high end in comparison to other freshening estimates from around the Arctic. Furthermore, the data reveals that renewal of the bottom water was prevented by freshening of the coastal water since 2004–2005. This shift toward fresher coastal water, in combination with freshening of the fjord's basin water, may impact the fjord's ecosystem functioning in the long term. The observations in this study provide new insights into the temporal variability of salinity and temperature and thus provide a critical step toward an impact assessment and identification of underlying processes driving freshening in Northeast Greenland.
