This year, visitors to California's beaches had the opportunity to observe a rare and simply stunning event - the bright blue glow of bioluminescent waves. Fans of walks on the night beach were able to take plenty of pictures and shoot a rare phenomenon with their phones, and surfers, having tried to ride such waves, admit that the light from them is so bright that it even dazzles.

An incredible sight

Back in late April, crowds of people began to flock to the beaches. The light show began here in March, but before that, residents were sitting in their homes due to the outbreak of coronavirus infection. So the start of the gorgeous glow coincided with the opening of the beaches after almost a month of closure due to the pandemic.

Such an amazing event takes place on the coast of Southern California every few years. Local residents recall that the last time it could be seen in 2012.

What Science Says

The reason for the glow of the waves is the simplest living organisms dinoflagellates, which are also called dinophytic algae. They are capable of bioluminescence and form "water bloom" during rapid reproduction.

During the day, clusters of dinoflagellates flock to the ocean surface to capture sunlight, at concentrations of up to 20 million cells per liter. Because of this, the water begins to cast a reddish-brown color, and this natural phenomenon is called "red tide". And at night, the waves sparkle with neon blue light. By the way, not all "red tides" produce bioluminescence.

The recent California event was one of the largest "light shows" seen here in the past.

“The brightest glow can be seen about two hours after sunset,” said the Scripps Institute of Oceanography at the University of California, San Diego.

Waves look especially impressive when they break and foam. Even in the sand, algae washed ashore by the waves can illuminate paths for beach visitors.

By the way, some of the red tides that occur on our planet (especially those that occur in the Mediterranean Sea) harm the life of marine life, as they are caused by species of microorganisms that produce harmful or even deadly toxins. In California, most of the blooming algae species are harmless and even beneficial, as they provide food for the inhabitants of the deep sea.

However, as the "red wave" fades away, decomposing algae leaves behind a strong odor, as this process reduces the amount of oxygen in the water, and this can lead to the death of some fish.

Such a bright "show" has not been seen for a long time

Locals claim that this year the sea sparkled especially brightly, which may be due to heavy rains, which caused the algae bloom.

Californian photographer Patrick Coyne has captured dolphins swimming at night in glowing waters - when dinoflagellate cascades are disrupted by waves or moving objects in the water (dolphins in particular), two chemicals produced by algae (the enzyme luciferase and the compound luciferin) react with a flash of electric blue colors. In his Instagram post, Coyne described his experience as "one of the most magical nights of his life."Surfer Blair Conklin says that when he glided over the ocean at night, the seaweed played the role of a torch.

The "phosphorescent" waves have worried locals as the light show has drawn crowds, which goes against the precautions associated with the pandemic. Surfers and ordinary onlookers, forgetting that it is better not to gather in large companies, began to simply enjoy the freedom and stunning glow.

Scientists have been observing the so-called red tides in a large section of the United States from Baja California to the coast of Los Angeles since the early 1900s. This phenomenon can last from several days to several months.

“Interestingly, there’s no way to predict how long this phenomenon will last or when it’s next,” says Michael Laz, bioluminescence expert at the Scripps Institute of Oceanography Institute.
