This paper gives a detailed review of IceBridge mission

including the on-board multiple sensors employed

the collected data

and the different levels of products. The on-board multiple sensors can be divided into five types: digital camera

lidar altimeter

radar

gravimeter

and auxiliary equipment. Prospects of research based on IceBridge data are described in four aspects: three-dimensional mapping of snow or ice

changes in glacier elevation and estimates of mass balance

detection of changes in sea ice thickness and distribution

and calibration and validation of satellite remote sensing observations. IceBridge will undoubtedly enhance the understanding of polar changes under global warming.
