Abstract: Denmark Strait Ocean Front(DSOF) has higher value in oceanographic research, such as provides a reference to the research on local climate change, fish distribution and the mesoscale eddy around the Denmark Strait. In addition, the research of the DSOF also has a higher application value in the military field. However, there has been lack of systematic research domestically and internationally for the DSOF. In this study, using WOA13 data, the location, spatial intensity distribution and the corresponding seasonal variations of the DOSF were analyzed. The results indicate that: the front axis at the west of 34°W is relatively stable above 150 m, whereas it varies with depths as well as seasons at the east of 34°W. The front intensity distribution is not uniform vertically and horizontally, and in general, the difference between maximum and minimum values are as higher as 3 times in the horizontal direction. The vertical salinity front mainly concentrates above 100 meters, and its intensity is decreasing with depth. The maximum value of temperature front intensity locates below the surface, and when the water depth is below 300 meters, it gradually decreases with the increase of water depth, but in some areas, such as at 27°W and 28°W, the front intensity increases quickly because of the affection of the bottom topography.
