The temporal observational network were established on 6 lakes located in the Mirror peninsula, the Larsemann Hills, East Antarctica (69 o 23 ́S, 76 o 20 ́E). The water level measurements were carried out during the period 24.12.2012–01.02.2013. The temporal hydrological gauges were established on the lakes Stepped, Sibthorpe, Progress, Sarah Tarn, Nella/Scandrett and Reid. The gauges were visited once a day to measure the water level above the reference point(s) with a known absolute height(s) (Table 1). The water level was measure with a tape-line allowing a precision 0.01 m. The geographical coordinates and absolute height of each point in the network (Fig. 1) were defined using GPS-receiver TRIMBLE (R8 GNSS, TSC 2). These measurements were done by Astashov V.V. and Zolotarev A.V. (“Ledgidroproekt”). The data set contains: 1. The table with the water levels (m) measured during 24.12.2012 – 01.02.2013 for 6 gauges (level_all.txt). The file format: #num is a number on the list date: DD/MM/YY … 01 03 05… : the number in the table (LakeWaterLevel.shp, compressed). No data indicated with “9999” in the table. 2. The map of the temporal observational network (figure1.pdf) on lakes located in the Mirror peninsula, the Larsemann Hills, East Antarctica with the map #13130 by the Australian Antarctic division, 2004 on the background. 3. The table with location and indexing of the water level measurements (LakeWaterLevel.shp, compressed). The flowing attributes are available: index in the ANARE74 (Numb) SCAR name of the (Name) Latitude and longitude WGS84, degree (Lat and Lon) Absolute height WGS84, meter (Heigth(m)) Coordinate System (CoordSys) Gauge number in the file level_all.txt and the table 1. The work has got financial support from the Academy of Finland (contract number 304345) and the logistic support of the the Russian Antarctic Expedition.
