Abstract. Detailed spatial geodatabase of aufeis in the Indigirka River, the basin area 305000km2, Russia was compiled from the Cadaster of aufeis of the North-East of the USSR published in 1958, topographic maps and Landsat images for 2013–2017. The aufeis area share varies from 0.26 to 1.15% in different river sub-basins within the studied area.

Digitized Cadaster (1958) contains the coordinates and characteristics of 897 aufeises with total area of 2064km2. The Landsat-based identification of aufeises for 2013–2017 allowed the description of 1213 aufeises on a total area of 128km2. The combined digital database of the aufeis is available at https://doi.pangaea.de/10.1594/PANGAEA.891036. The satellite-derived total area of aufeis is 1.6 times less than in the Cadaster (1958). At the same time, more than 600 aufeis identified by Landsat images analyses are missing in the Cadaster (1958). It implies that the aufeis formation conditions may have been changed between the mid-20th century and the present.

About 60% of total area presents 10% of the largest aufeis. Most aufeis are located in the elevation band of 1100–1300m.

The interannual variability of the aufeis area was estimated by the example of the Bolshaya Momskaya naled (aufeis) and the group of large aufeis in the basin of the Syuryuktyakh River for the period of 2001–2016. The results of analysis indicate a tendency towards a decrease in the area of the Bolshaya Momskaya naled in recent years, at the same time the reduction in the aufeis area in the basin of the Syuryuktyakh River has not occurred.

Short summary
Aufeis are one of the glaciation forms and formed by a complex interconnection between river and groundwater. The dynamic of aufeis assessed by the analysis of remote sensing data can be viewed as an indicator of groundwater changes in warming climate which are otherwise difficult to be observed naturally in remote arctic areas. Developed spatial geodatabase shows that the aufeis formation conditions may have been changed between the mid-20th century and the present in the Indigirka River basin.
