| Research Abstract |
Information of the thickness of sea ice is essential to predict a long-term change of the sea ice in the cold region. We have been observing sea ice using a X-band Doppler radar depoyed in Monbetsu city. Three-dimensional disply of observed sea ice echo indicates an irregularity of the sea ice area. However, it is not confirmed whether this irregularity is related to thickenss of sea ice, or not. Therefore we measured horizontal distribution of the height of sea ice by using aircraft and compared it with the irregularity of the sea ice detected by the X-band Doppler radar. As a result, both data correlated very well. This fact demonstrates that thickness of the sea ice could estimate by a three dimensional scanning radar.
