Ocean Network Canada has an article on their website titled, " Fraser River Plume" and another, " Understanding the Oceans" with essays explaining their work studying the surface currents.

(Left image original source: Ship-level view of the Fraser River plume in southern Georgia Strait, showing fine sediments in the otherwise blue-green waters. In Spring, as snow melts in the mountains, the fresh water flow increases significantly and great quantities of sediment are deposited. Sediment carried in this plume then precipitates from the surface, accumulating on the Fraser River Delta below. Fresh water, which is less dense than salt water, spreads in a shallow (approximately 1 m deep) plume at the sea surface. The caption explains that this brown river plume is only about one meter deep:Ī sharp boundary appears as sediment-laden freshwater is discharged from British Columbia's Fraser River into the Salish Sea. The proper original creative commons labeling on the photo points to a Flickr photo album maintained by Ocean Networks Canada. This view matches an Almay stock photo of ' The Canadian ferry Coastal Renaissance sailing between Vancouver City and Nanaimo on Vancouver Island'.Īnother image of the Fraser River plume in the Strait of Georgia, reproduced many times in social media posts, mis-labeled as 'oceans not mixing' is pictured below on the left. Thirty-five seconds into the video, the camera turns to view the deck of the ferry and large wave logo. I have registered the original video in my computer for copyright Thank you!

The river water (Fraser River) flows into the ocean water (Strait of Georgia): a short video clip shot while onboard the BC Ferries boat from Nanaimo, Vancouver Island (Duke Point) to Vancouver (Tsawwassen). The original video filmed by Maryan Pearson with piano soundtrack by Donny Pearson is captioned: (Source: Facebook screenshot taken on Fri Jan 29 21:31:07 2021 UTC) This is what the post looked like on Facebook at the time of writing: Therefore, the two oceans have different densities, which makes them almost impossible to mix. And why do these waters not mix? Because there is a huge difference in salinity between the clear water that comes from melting glaciers, which is cool and low in salt, while the water from the second ocean has a high salt concentration. This phenomenon can be also be seen in the Gulf of Alaska. The extraordinary point where the Atlantic Ocean and the Pacific Ocean meet, without mixing! The two oceans do not mix.
