Antarktika'da Küresel İklim Değişikliği İzleme için GNSS İstasyon Tasarımı: TUR1 ve TUR2 GNSS İstasyonlarının 4. Ulusal Antarktika Bilim Seferi’nde Antarktika Horseshoe Adası'na Kurulumu

Son yıllarda uzay tabanlı konumlama sistemleri, GNSS Meteorolojisi ve GNSS Reflektometresi teknikleri kullanılarak gözlemlenen atmosferik su buharı, deniz, buz ve kar seviyeleri gibi önemli parametrelerle küresel iklim değişikliğinin izlenmesinde etkili bir destekleyici araç haline gelmiştir. Küresel ölçekte tüm bölgelerden daha hızlı ısınan Antarktika'da iklim değişikliğini incelemek, gelecekteki iklim değişikliğini daha doğru tahmin etmek için çok önemlidir. Dünya'nın iklim değişikliği etkilerinin izlenebilmesi amacıyla, 118Y322 No’lu TÜBİTAK projesi kapsamında GNSS Meteorolojisi ve GNSS Reflektometresi teknikleri ile 24 Şubat 2020 tarihinden itibaren Antarktika’da atmosferik su buharı değişimleri, kar derinliği ve buz kalınlığı değişimleri gözlemlenmektedir. Bu çalışmada, Troposfer ve Deniz Seviyesi Gözlem İstasyonu (TUR1) ile Troposfer ve Kar / Buz Seviyesi Gözlem İstasyonunun (TUR2) tasarım çalışmaları ve 4. Ulusal Antarktika Bilim Seferi’nde Antarktika Horseshoe Adası’na kurulum aşamaları anlatılmıştır. Bu çalışmalar, meteorolojik koşullar, şebekeden bağımsız ve batarya ile bütünleşik enerji sisteminin en sağlıklı şekilde güneş ve rüzgâr enerjisinden beslenmesi ve bölgede oluşabilecek buzul oluşumu ve kayaç parçalanması gibi jeolojik parametreler de göz önüne alınarak yapılmıştır.

GNSS Station Design for Global Climate Change Monitoring in Antarctica: Installation of TUR1 and TUR2 GNSS Stations on Horseshoe Island in Antarctica During the 4th Turkish Antarctic Science Expedition

In recent years, space-based positioning systems have become an effective supporting tool for monitoring global climate change by important parameters such as atmospheric water vapor, sea, ice and snow levels observed by using GNSS Meteorology and GNSS Reflectometry techniques. Studying climate change in Antarctica, which is warming faster than all of the regions on a global scale, is very important to predict future climate change more accurately. In order to monitor climate change effects of the Earth, tropospheric water vapor variations, snow depth and ice thickness changes have been observing in Antarctica since 24 February 2020 by means of GNSS Meteorology and GNSS Reflectometry techniques within the scope of the TUBITAK Project No. 118Y322 In this study, designing studies of Troposphere and Sea Level Observation Station (TUR1) and Troposphere and Snow / Ice Level Observation Station (TUR2) and installation steps to Horseshoe Island in Antarctica during the 4th National Antarctic Science Expedition are explained. These studies was carried out by taking into account the meteorological conditions, the healthiest feeding of the off grid battery integrated energy system from solar and wind energy and geological parameters such as glacial formation and rock fragmentation that may occur in the region.
