A group of avid photographers in New Zealand has been chasing "glowing waves" at sea, which is a natural phenomenon called "bioluminescence" in which glowing algae give waves an electric blue aura.

Enthusiasts say New Zealand's beaches are the perfect spots for chasing the glowing waves.
While there's scarcely any way to predict when the glowing waves will appear, bioluminescence is extremely rare on land, yet pretty prevalent in the ocean.
About 80 percent of the animals that live 200 to 1,000 metres below the sea surface are bioluminescent.
The glow usually comes in different colours on land, but in oceans the waves usually appear blue-green.
This fascinated phenomenon enticed a multitude of photographers to catch a glimpse of the enchanting waves.
And with that, scientists say, sea organisms communicate, lure or detect prey or beat back predators.
The most widely-accepted explanation is that organisms glow whenever big fish swim by, in turn fending off smaller fish that rely on algae as sustenance.
Summer is generally the best time to spot the waves, especially nights following rainstorms as blue patches pulsate intermittently across the shore.
