Detection of 1.5 million new marine organisms

A research ship has discovered more than 1 million new species of creatures after the discovery on the Atlantic, Pacific and Indian Ocean.

Tara Expedition has made a long journey of 112.654km through the Atlantic, Pacific and Indian Ocean over 36 months, to discover new species. The French-based expedition docked in London last week.

The newly discovered Platynereis Dumerei worm.

During this expedition, the team took more than 30,000 samples of seawater at different points in the ocean and found 1.5 million new species of organisms, ranging in size from 1cm to several parts of mm.

The team said their findings could change our thinking about the effects of climate change on oceans around the world. The discoveries show that the ocean is being hurt by human activities. Scientists have recorded about 50,000 pieces of plastic waste / 2.5 km ² .

Shrimp species Emmanuel Reynaud.

These pieces of plastic waste will not decompose for hundreds of years and they can enter the chain through fish, seabirds and other marine animals. Their toxins can seep into the sea and into the human body through seafood.

'Nobody has ever done research on this scale before. We will continue to analyze lab results in a few years. The purpose of these studies is to understand the factors, including pollution and temperature changes in creating the current ecosystem, ' said Dr. Chris Bowler, researcher, on the Daily Mail. .

Dr Chris Bowler added that if an animal species is susceptible to temperature changes, it can destroy the food chain it participates in and then affect fishermen. Therefore, scientists want to find out the role of each species in a marine ecosystem, so that the oceans can be predicted in the next 50 or 100 years.
