The Entrance Island Lighthouse is a manned light station. It was built in 1875 to guide ships into Nanaimo harbour from the Strait of Georgia, and is easily seen from the Horseshoe Bay to Departure Bay ferry. The Tsawwassen to Duke Point ferry passes right by it.[2]
Oceanographic research
[edit]The Entrance Island Lighthouse is one of 12 lighthouses part of the British Columbia Shore Station Oceanographic Program, collecting coastal water temperature and salinity measurements everyday since 1936.[3] Their data show an increase in coastal water temperatures of 0.15 °C per decade. This trend is believed to be a result of anthropogenic climate change.[4]
