This video was sent to me by my good Youtube friend Shaun way over there on Vancouver Island. Shaun was out for his usual evening walk near his home at Duncan, on the Crofton boardwalk and this is what he saw! It's an alarming, 'Red Tide' Algae Bloom HSB!
Shaun tells me,
A "red tide" is a common nickname for a harmful algal bloom (HAB). It occurs when microscopic, plant-like marine organisms (usually dinoflagellates) multiply rapidly, causing the water to become visibly discolored, often taking on a reddish or brownish hue.While most algae blooms are harmless and serve as the base of the ocean food web, "red tides" are a major concern because they produce dangerous toxins. Causes,- these blooms are fueled by a combination of sunlight, calm waters, and elevated nutrient levels. The nutrients can come from natural ocean upwelling or agricultural runoff (fertilizers and pesticides) entering the water.Impacts on Marine Life and the EnvironmentToxin Production: The algae release phycotoxins (like saxitoxin) that can kill fish, marine mammals, and seabirds.Oxygen Depletion: When the massive bloom of algae eventually dies and decays, it consumes the oxygen in the water, causing "dead zones" where surviving fish can easily suffocate.
