在Nares海峡获得的数据被用来估计极地海洋和巴芬湾北部之间的水、热和盐的输送。纳尔海峡年输水量为2.1 × 10~4 ~3 ± 30%，相当于平均流量0.67 × ~6 m~3∙S−1，约占极地海洋总输水量的15%。在参考温度为0.1 C的情况下，由于冷水和冰的流出而输入极地海洋的年净热量为15 × 10 19 J ± 50%，这一体积约占进入极地海洋的平流热输送总量的7%。极地海洋盐类年平均出口量为6.7 × 1014 kg ± ，约占总出口量的6%。对整个加拿大群岛的总运输量进行了估算，结果表明，它们在极地海洋和世界海洋之间的总交换中占有相当大的比例。
Data obtained in Nares Strait are used to provide estimates of the transports of water, heat, and salt between the polar ocean and northern Baffin Bay. The annual volume export of water through Nares Strait is 2.1 × 104 km3 ± 30%, which is equivalent to a mean flow of 0.67 × 106 m3∙s−1 and which is about 15% of the total outflow of water from the polar ocean. The annual net heat input into the polar ocean due to the outflow of cold water and ice is found to be 15 × 1019 J ± 50% assuming a reference temperature of −0.1 C. This volume is about 7% of the total advective heat transport into the polar ocean. The mean annual export of salt from the polar ocean is 6.7 × 1014 kg ± 30% or about 6% of the total export. The total transports through the whole Canadian archipelago are estimated and it is shown that they are appreciable fractions of the total exchanges between the polar ocean and the world ocean.
