“…Other aspects of sea level changes also must be considered, for example, a considerable amount of non-tidal variability due to storm surges (Woodworth & Hibbert, 2018). Continuous tide measurements are performed at Vernadsky station stations since 1958 (Cartwright, 1979;Cisak et al, 2008;Woodworth & Hibbert, 2018) and are available on Permanent Service for Mean Sea Level website (https://www.psmsl.org/ data/obtaining/stations/913.php) (Holgate et al, 2013).…”

“…Only during the Ukrainian expeditions (after 1996) creation of large scale plans of the Argentine Islands, mostly using photogrammetric methods, as well ice surface mass balance measurements were performed (Cisak et al, 2008;Greku et al, 2006;Hlotov, 2008;Hlotov et al, 2003;Levashov et al, 2004;Litvinov et al, 2006;Tretyak et al, 2016). Decreasing surface volumes were detected from all surveys (Hlotov, 2008).…”

High-resolution orthophoto map and digital surface models of the largest Argentine Islands (the Antarctic) from unmanned aerial vehicle photogrammetry

et al. 2020

This study presents the first high-resolution orthophoto maps and digital surface models (DSMs) of the largest Argentine Islands, West Antarctica. Aerial surveys with small unmanned aerial vehicle (UAV) were performed in Austral summer, 2018, taking 10,041 aerial photographs. Accuracy requirements were ensured using ground control points (GCPs). A resolution of 3.4 and 6.8 cm/px of orthomosaics and DSMs is reached on average, and the RMS reprojection error is 0.22 m on average. We report the morphometric parameters of surveyed islands and discuss issues related to accuracy and the usage of UAVs in polar conditions. This study demonstrates that small and low cost UAVs can be successfully used in harsh polar conditions to obtain accurate orthomosaics and DSMs of mainly glaciated terrain. We provide all generated materials in full resolution available in a scientific data repository that could be used for the monitoring of ice cap changes, vegetation cover, and wildlife populations.

“…Hlotov et al (2003) also observed that some parts of the glaciers are experiencing greater losses of ice than others, but they concluded that the ice caps are shrinking in general. This observation was supported by a comparison of British Antarctic Survey aerial photographs and Quick Bird satellite images, suggesting that the main receding area is the western part of the ice cap (Cisak et al 2008). Cisak et al (2008) calculated that since 2000 the Galindez Island ice cap has lost 2-3% of its volume in general, which corresponds to 20 000 m 3 year -1 .…”

“…After 1996, when the former British Faraday station (now called Akademik Vernadsky) was transferred to Ukraine, some new methods were used to study the ice caps of the Argentine Islands. Ground-penetrating radar and vertical electrical resonance sounding methods were used to measure the thickness of the Galindez Island ice cap (Levashov et al 2004, Bakhmutov et al 2006), and monitoring of the frontal parts of the ice caps on Galindez and Winter islands was started in 2002 using the photogrammetric method (Hlotov et al 2003, Cisak et al 2008, Tretyak et al 2016). Phototheodolite measurements were taken on Galindez Island (Hlotov et al 2003), and terrestrial laser scanning was used for the first time for observation of the termination line of the ice caps on Galindez and Winter islands in 2014 (Tretyak et al 2016).…”

Subglacial topography and thickness of ice caps on the Argentine Islands

et al. 2019

This study presents the first subglacial topography and ice thickness models of the largest ice caps of the Argentine Islands, Wilhelm Archipelago, West Antarctica. During this study, ground-penetrating radar was used to map the thickness and inner structure of the ice caps. Digital surface models of all studied islands were created from aerial images obtained with a small-sized unmanned aerial vehicle and used for the construction of subglacial topography models. Ice caps of the Argentine Islands cover ~50% of the land surface of the islands on average. The maximum thickness of only two islands (Galindez and Skua) exceeds 30 m, while the average thickness of all islands is only ~5 m. The maximum ice thickness reaches 35.3 m on Galindez Island. The ice thickness and glacier distribution are mainly governed by prevailing wind direction from the north. This has created the prominent narrow ice ridges on Uruguay and Irizar islands, which are not supported by topographic obstacles, as well as the elongated shape of other ice caps. The subglacial topography of the ice caps is undulated and mainly dependent on the geological structure and composition of magmatic rocks.

Due to global warming, the glaciers and ice systems of Antarctica and the Antarctic Peninsula have been significantly changing in shape and size in recent decades. Therefore, to control, forecast and prevent such processes, it is necessary to constantly monitor and analyse changes in the basic parameters of glaciers and ice systems. This paper proposes a study of changes in the area of ice caps located on the Galindez, Winter and Skua islands (Argentine Islands, West Antarctica). The study is based on the integration of different spatio-temporal datasets into a single system for retrospective geographical monitoring of changes in the area of Galindez, Winter and Skua islands ice caps. The system for integrating space-time datasets is the UTM coordinate system (zone 20, South). Using transformed archival cartographic materials, as well as recently obtained orthophotos, the boundaries of the glaciers in different periods of research were digitized. Based on the identified boundaries, the significance of changes in the area of island glaciers, as well as the rate of their change during 1935–2019, were determined. Based on the integration of different spatio-temporal datasets into a single system, retrospective-geographical monitoring of changes in icecaps area during 1935–2019 was performed. The ice caps were found to be experiencing systematic decrease in area with average linear rate of decrease from –0.30%/year to –0.37%/year. A detailed analysis of all integrated spatio-temporal data sets including determination of the cause of changes in the area of the Galindez, Winter and Skua islands' ice caps is a promising topic for further research.
