Nhà khoa học khám phá 100 loài sinh vật biển mới ở New Zealand
nhà nghiên cứu cho biết, phát hiện từ vùng nước phần lớn chưa được khám phá của Bounty Trough, cho thấy “chúng ta còn chặng đường dài phía trước để hiểu nơi tìm thấy sự sống ở đại dương”

A team of 21 scientists set off on an expedition (thám hiểm) in the largely uncharted waters of Bounty Trough off the coast of the South Island of New Zealand in February hoping to find a trove of new species (giống loài mới).
The expedition paid off, they said on Sunday, with the discovery (khám phá) of 100 new species, a number that was likely to grow, said Alex Rogers, a marine biologist who was a leader of the expedition.
Dozens of mollusks, three fish, a shrimp and a cephalopod (bạch tuộc) that is a type of predatory mollusk were among the new species found in the expedition, which was led by Ocean Census, a nonprofit (phi lợi nhuận) dedicated to the global discovery of ocean life, the National Institute of Water and Atmospheric Research in New Zealand, and the Museum of New Zealand Te Papa Tongarewa.
Ocean Census was founded last year by the Nippon Foundation, a Japanese philanthropic organization, and the U.K.-based ocean exploration (thám hiểm đại dương) foundation Nekton. When it began its work, Ocean Census set a goal of finding at least 100,000 new marine species in a decade.
Trawling the depths at 4,800 meters — or roughly the equivalent to Mont Blanc, the highest peak in the Alps — researchers collected 1,791 samples.
Given its depth, Bounty Trough is not of great interest to fisheries and therefore is poorly sampled, Dr. Rogers said. Geologists have surveyed this area but biologists have not.
Worldwide, about 240,000 marine species have been discovered and named to date but only 2,200 species are discovered each year on average, according to Ocean Census.
