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).
