The depths of the oceans hold immense mysteries.

Though researchers and experts have clarified some of these anomalies, there are still some fascinating underwater events that can not really be explained.

Here’s a list of 10 most bizarre ocean phenomena:

1. Underwater Crop Circles

These “mystery circles” were first spotted in 1995 off the coast of southern Japan. 16 years later, the culprit behind the mystery circles was finally caught in the act. In 2011, scientists discovered a male puffer fish creates this elaborate designs to woo females.

2. Tectonic Plate Gap between Eurasia and North America

The tectonic plates are pulling apart at about one inch per year. The area is riddled with faults, valleys, volcanoes and hot springs due to the plate pulling apart.

3. Underwater Rivers

The underwater river is formed when the fresh top water meets the exposed salty groundwater. The different density levels in two waters causes them to layer.

4. Meeting of Fresh and Salt Water

When fresh water and saltwater meet in an estuary, they do not always mix. Because fresh water flowing into the estuary is less salty and less dense than water from the ocean, it often floats on top of the heavier seawater.

5. Green Flash

Green flashes or green rays are optical phenomena that sometimes occur when right before or after sunset. It usually lasts for a second or two.

6. Frost Flowers

Frost flowers are ice crystals formed on thin sea ice when the atmosphere is colder than the underlying ice.

7. Brinicle

This phenomenon is caused by cold, sinking brine which is more dense than sea water. It forms a brinicle as it makes contact with warm water below the surface.

8. Rogue Waves

It is a really large and spontaneous surface waves that occur far out in open water. It is even a threat to large ships and ocean liners.

9. Maelstrom

It is a vast and powerful whirlpool that has a downdraft that would quickly suck up whatever is in its path.

10. Bioluminescence

The light is produced by marine creatures. Certain chemicals in their bodies react to atmospheric oxygen results in the emergence of bioluminescent light.
