Daily observations of weather conditions were made at all of the CAE semi-permanent camps and during many of the trips by dog team or schooner. Much of this information has never been analysed, but remains an important source for current studies of climate change in the Arctic. Observations were maintained throughout the winter in spite of the hazards of blizzards and prowling polar bears.

Tidal observations were obtained at seven different places along the Arctic coast in the years 1914 and 1915, and also in the northern islands in 1916. These were the first observations from this part of the Arctic and were obtained with great difficulty. Each tide gauge had to be protected by a shelter, usually a snowhouse in winter, and heated with a kerosene lamp. The results showed that the direction in which the tide progresses in the Beaufort Sea is from the north, proceeding southward and eastward along the shores. These results confirmed the view that the main tide of the Arctic Ocean enters from the North Atlantic through the wide opening between Greenland and Norway (Dawson 1920 CAE Report Volume X).
