The blue glow that has been observed in waves at beaches in eastern Singapore over the past few nights would likely last for the next two to four days, said a marine microbiologist.

The bright blue waves are caused by a bloom of marine microorganisms called dinoflagellates, whose bioluminescence is activated when the waters are disturbed.

Assistant Professor Rebecca Case from the School of Biological Sciences in Nanyang Technological University (NTU) told The Straits Times on Thursday (March 24) evening: "I am fairly confident to say that this has got two to four more days to it."

The phenomenon has been occurring in waters off Singapore's eastern coastline.

However, because the bloom depends on environmental factors such as temperature and water salinity, it is hard to predict if the current bloom will persist beyond the next four days.

Prof Case, who is principal investigator at NTU's Singapore Centre for Environmental Life Sciences Engineering and specialises in algal-bacteria interactions, said: "After the peak of the bloom, it usually takes around two to four days for it to completely dissipate.


It is hard to predict when these blooms will occur here.

"These blooms can last for one to two weeks."

She added: "If people want to see the blue waves, they should go this weekend."

In response to a query by The Straits Times, the National Parks Board said that the scale of bioluminescence observed recently could reflect undesirable changes in water quality, such as elevated nutrient levels.

However, it added that these blooms of bioluminescent microorganisms are not known to be harmful or toxic and thus are unlikely to negatively impact marine biodiversity or human health.

The phenomenon came to ST's attention when it was documented at Pasir Ris Park by Mr Eric Teo in a Facebook post on Tuesday.

When ST visited Changi Beach Park on Thursday night from 8 to 11pm, the blue light in the waves got progressively stronger later in the night, peaking at around 11pm.

Although the bioluminescence is activated when waters are disturbed, Prof Case said that prolonged disturbance by boats can cause the dinoflagellates to run out of energy and go dim.

She added: "The presence of background light also makes the light less easy to see."

Many Singaporeans were at Changi Beach Park on Thursday night to see the blue waves.

ST spotted at least a hundred people along the shoreline, splashing in the ocean and creating neon footprints in the sand.

One of them was Mr Kenny Chen, 32, an engineer, who was there with some of his friends. He said: "When my friends and I saw media reports on the blue waves in the middle of the week, we decided to come down because it looked interesting.

"I am surprised by how bright the lights are and they look very nice."

Some of them, like university undergraduate Ian Koh, were swimming in the sea.

Mr Koh, 20, who was there with two of his friends, said: "For the past hour or so we were trying to create many nice effects, such as by lobbing stones into the water and splashing as much of the water surface as possible."

Mr Koh, who was at the beach from 8.30 to about 10pm, said that the glow in the water got much brighter at 9.30pm, after the ferry service from the nearby Changi Ferry Terminal to Pulau Ubin stopped running.

He added that he would be going back over the next two to four days to play in the sea again.

He said: "We don't know when this will come back again given that this is a natural phenomenon, so it's definitely worth coming back to check it out."

Adult scorpions glow under UV light but their babies don’t which is useful when you wanna get some contrast.
There are at least 20 babies on this mum’s back. The babies latch on with suckers which they lose after their first molt. They can move around freely after that

By night the blue algae blooms (dinoflagellates) lights up. Followed by day could be the water reptiles - crocodiles on their hunts.
PHOTO: Could the activated bioluminescence when the waters are disturbed, be a prophetic significance of evil omen? Remember, our Covid-19 could be replaced by something too huge to control. Our marine microbiologist may not be able to offer what is going to happen next.

From an economic perspective, there are four possible futures: a descent into barbarism, a robust state capitalism, a radical state socialism, and a transformation into a big society built on mutual aid. Versions of all of these futures are perfectly possible, if not equally desirable.

The upside of this is the possibility that we build a more humane system that leaves us more resilient in the face of future pandemics and other impending crises like climate change. [2]

Bible's Revelation describes four horseman of the Apocalypse who appear when the seven seals are opened. The first symbolizes Christ. The second represents war and bloodshed. The third is identified with famine and the fourth is associated with pestilence and death. Some Christians claim that COVID-19 is proof that the plagues of the book of Revelation, and in particular the seven Seals of Revelation 6:1–8:1, are occurring now and Jesus’ return is imminent. For them, Revelation has indeed predicted the COVID-19 pandemic. Corona has been associated with the fourth horseman. Pestilence in this context refers to full scale disease outbreaks.

Since it was first written in 95 AD by John of Patmos, the Book of Revelation has deployed to account for world events in terms of the ‘end times’. It was finally accepted as the last book of the Christian Cannon in 367CE by Bishop Athanasius of Alexandria. For some it is a direct criticism of power concentrated in the hands of a small elite and systemic injustice both resulting in poverty, famine, hunger, pestilence and disease.

But Revelation is not the only book in the Christian Bible to speak about an end-time return of disease outbreaks. According to the Gospels, Jesus himself stated that pandemics of pestilence would happen before His return: “For nation shall rise against nation, and kingdom against kingdom: and there shall be … pestilences … in divers places” (Matthew 24:7; see also Mark 13:8 and Luke 21:11). At this moment Russia is attacking Ukraine for the 35th day.

Fears pertaining to atomic destruction, lethal disease, and environmental catastrophes have become prevalent. [3]

So, are all our present days' happening, the indication of 'the last days'?
