Chinese “Xue Long” breaker made its first voyage to the Arctic Ocean for scientific expedition from July to September, 1999. The tethersonde meteorological tower (TMT) sounding system was used to probe the temperature, humidity, air pressure, wind direction and wind speed on different underlying surfaces above the Arctic Ocean. The probed data were used for calculating the roughness length z0, momentum flux M, drag coefficient CDD, sensible heat flux Hss, bulk transfer coefficient CHH for sensible heat, latent heat flux HLL, and bulk transfer coefficient CEE for latent heat of air-ice-sea on different underlying surfaces. They vary within the ranges of (0.2 - 1.0) mm, (1.14-9.19) × 10-2N/m2, (0.87-1.76) × 10-3, - (4.2 - 12.5) W/m2, (0.84 - 1.37) × HT3, - 6.6 -23.6 W/m2 and (0.85 - 1.40) ×10-3, respectively. It shows that the drag coefficient is greater than the latent heat transfer coefficient, and again the latent heat transfer coefficient is larger than the sensible heat transfer coefficient. Besi
