Abstract

We extracted a surface displacement map of Canisteo Peninsula and the surrounding area in West Antarctica by applying 4-pass DInSAR technique to two ERS-1/2 tandem pairs and analyzed the surface displacement of glaciers and sea ice. In the displacement map, glaciers showed fast motion pushing the adjoining land-fast sea ice which has the displacement in the same direction as the glacier. Cosgrove ice shelf showed large displacement pushing the adjoining land-fast sea ice as well. Some sea ice indicated the displacement that is opposite to the land-fast sea ice. This was because the type of the sea ice is drift ice that is affected by ocean current. Therefore, we could confirmed the boundary between land-fast sea ice and drift ice. It was difficult to distinguish ice shelf from ice sheet because they showed similarities both in brightness of the SAR images and in fringe rates of the interferograms. However, a boundary between fast-moving ice shelf and stable ice sheet was easily confirmed in the displacement map after the phase unwrapping process.

본 연구에서는 서남극 Canisteo 반도와 그 주변 지역이 촬영된 2쌍의 ERS-1/2 tandem pair에 4-pass DInSAR 기법을 적용하여 표면 변위도를 생성하였고, 빙하와 해빙의 표면 변위를 해석하였다. 표면 변위도에서 빙하는 매우 빠른 움직임을 나타냈으며 인접해 있는 정착빙을 밀어내어 정착빙 표면에서는 빙하와 같은 방향의 변위가 관찰되었다. Cosgrove 빙붕도 큰 변위를 나타냈으며, 인접해 있는 정착빙을 밀어내는 것이 관찰되었다. 일부 해빙은 정착빙과 반대 방향의 움직임을 보였다. 이는 해빙이 해류에 영향을 받는 유빙이기 때문이며, 이로부터 정착빙과 유빙의 경계를 확인할 수 있었다. 빙붕과 빙상의 표면은 SAR영상에서 유사한 밝기를 보이며, 간섭도에서도 비슷한 정도의 간섭띠 변화율을 나타내 두 빙체를 쉽게 구분 할 수 없었다. 그러나 움직임이 큰 빙붕과 변위가 거의 없이 안정적인 빙상의 경계를 절대위상복원 후 생성한 변위도를 통해서 쉽게 확인할 수 있었다.
