Scientists at Otago University in New Zealand, after examining a type of algae gene that grows off the coast of the country, have found records of earthquakes in the area that occurred hundreds of years ago.
The researchers revealed that the ‘bull kelp’ gene, which is abundant on the coast of the South Island of New Zealand, carries signs of an earthquake that occurred 800 years ago, reported Science X Network.
The quake was so severe that it lifted some parts of the sea floor above the water surface. The disaster will strip some of the newly formed seafloor, the researchers suggest, allowing seaweed to occupy new surfaces. Seaweed is known as an aggressive seaweed that migrates when new opportunities for growth and development come, the report added.
When scientists try to find out if a newly formed seabed may have been inhabited by seaweed migration, evidence shows that it does exist.
Earthquake intensity occurred in South New Zealand along the coastline near Dunedin about 800 years ago. The researchers took seaweed samples that inhabit a stretch of 100 kilometers on the same beach.
They found that the bull seaweed that lives within a 25 km stretch that was likely thrown into the air during an earthquake, differed from their neighbors of the same species on both sides, which did not experience the same geological violence.
“We are just amazed when we look. We can see where zones are raised just by looking at genetics,” Jon Waters, a professor of zoology at Otago University, told NOW.
The results showed seaweed is a species of algae territorial, according to the researchers. This study outlines evidence of how long and new seaweed has remained unmixed for more than 800 years despite being so close in geographical distance.
Their findings were published in a journal Proceedings of the Royal Society B.
