[2] The practice of recording ocean water temperature and salinity levels in the area was initiated in 1914 at the Pacific Biological Station in Nanaimo.
The methodology of the sampling was originally designed by oceanographer John P. Tully, and was never modified in order to maintain the homogeneity of the data.
[3][4] Data from the Amphitrite point and Kains island lightstations, which started reporting in the mid-1930s, show an increase in coastal water temperatures of 0.08 °C per decade.
On the other hand, data from the Entrance Island station, which started reporting around the same time, show an increase in coastal water temperatures of 0.15°C per decade.
