    • A lag correlation analysis, comparing the water temperature time-series in the Barrow Canion with the water temperature time-series at station HSN/NHC, was performed. The results indicate that it takes 7-61 days for Pacific Summer Water to be transported from the Barrow Canion to station HSN/NHC. Similarly, the mean sub-surface water temperature in the Barrow Canion was examined. Then it was found that the mean water temperature in the Barrow Canion was higher than that of the station HSN/NHC, and the water temperature decreased during the transport process. The decrease in water temperature was greater in period 2 (2015-2019) than in period 1 (2003-2005). (Figure 5)
