Tourists and locals were treated to an insanely red harbour waters in Vancouver due to an algae bloom. Some people were lucky enough to get pictures of the unusually red water and it seriously looks like something out of The Shining or another scary movie.\nThroughout the week, several photos have been posted online of the Vancouver harbour. These were not ordinary pictures, as the waters looked bright red!\nAccording to Huffington Post Canada, this is not the first time the waters in Vancouver have turned this vibrant colour and it is entirely due to an algae bloom. The algae producing this phenomenon — Noctiluca scintillans — is erroneously known as “red tide”. It is not to be confused with red tide poisoning in fish.\nAccording to the National Ocean Service, red tide poisoning occurs when colonies of algae grow out of control while producing toxic effects bivalve shellfish and other marine mammals in extreme cases.\nIf these shellfish are eaten by humans, it can lead to serious and potentially fatal illnesses such as a “paralytic shellfish poisoning” and “amnesic shellfish poisoning.”\nNo filter - that is some 💩💩💩 looking water in English Bay. People were swimming in it. #Redtide is part of it too. #gross #water #Vancouver #YVR #vancity #cityofvancouver @AM730Traffic @GlobalBC @CKNW @KOwsianski pic.twitter.com/Mhvjs9DTy1— Trish Jewison (@TrishJewison) July 17, 2019\nBlooms like this can be caused by a number of things, including climate change, human activity or a combination of tides and temperatures.\nNot much improvement on our red tide situation as seen in Coal Harbour. pic.twitter.com/SghA5ejTlh— John Streit (@johnrstreit) July 18, 2019\nElysha Gordon, Canadian shellfish sanitation program coordinator with the DFO, told CBC News that the colourful algae is not harmful to humans.\nhttps://www.reddit.com/r/vancouver/comments/ce319x/photo_red_tide_in_coal_harbor_last_weekend_kinda/ from https://www.reddit.com/r/vancouver\nBlooms usually occur from May to September. In fact, this is not the first time this has happened in Vancouver. There are tons of pictures and videos online from previous years showing the eerie colour.\nThe #redtide bloom as seen from #CTVChopper9 around Burrard Inlet and English Bay this week. pic.twitter.com/hu9UclQ06i— Pete Cline (@yvrnewsphotog) July 12, 2019\nThere is no clear answer as to how long this algae bloom will stick around in the Vancouver harbours and beaches, but as long as conditions remain ideal for the bloom, it will be staying.\nJust a wee bit o' #redtide in #burrardinlet this summer. #Vancouver #YVR #vancity @AM730Traffic @GlobalBC @CKNW @604Now @MyVancouver @1K_things @downtownvan @StanleyParkVan #stanleypark #lionsgate #bridge #helicopterview #westcoast pic.twitter.com/vBXIZwAKe0— Trish Jewison (@TrishJewison) July 17, 2019\nBC has been home to some seriously weird phenomena lately. Most recently, a large “fried egg” jellyfish that grows up to 20 feet long was spotted swimming off the Sunshine Coast.
