--001a11353372eb1fbf050fc303ed Content-Type: text/plain; charset=ISO-8859-1 Due to the specific atmospheric and wind conditions, it appears that I did not miss a higher tide on the 20th. Therefore, I presumably captured the maximum impact of ice cakes on the Port Williams bridge. I received the following note from Roy Bishop: "Regarding the height reached by the tides on the 19th and 20th (low-to-high ranges of 16.2 and 16.7 m, respectively, on the BNS Calendar), you are correct that the tide on the 19th was the higher of the two. It was difficult to tell by how much because of the snow and ice conditions, although the tide on the 19th was the highest I have seen at my cottage at Evangeline Beach. The barometric pressure was higher on the 20th which would lower the high tide level. The difference in winds on the two days likely also had an effect, although I do not have enough wind information to say which way the tide height may have been affected."
