An airborne laser altimeter using a Nd:YAG laser was constructed to test the usefulness of the laser altimetry in snow and ice regions. The experiments were conducted to measure sea ice in the Sea of Okhotsk off the Hokkaido Island, Japan at winter seasons in 1993 - 1995. Distributions of ice freeboards, mean elevations and ice concentrations were investigated from the data. The mean freeboard was found to correlate very well with the ice concentration. This result shows the possibility of estimating ice amount from the ice concentration and approved the effectiveness of the laser altimetry. A new laser altimeter is being developed to incorporate a beam scanning capability to measure sea ice more effectively. Also discussed in this scanning laser altimeter using a coherent detection technique.
