    Scientists at the University of Hawaii at Manoa studied a huge area in the eastern part of the Pacific Ocean known as the Clarion－Clipperton Zone，or CCZ to find and study new sea species.

Diva Amon，a researcher at the University says usually deep sea biologists think there is not a lot living in the deep sea.

“But we found that actually there is quite a lot living there，and so that was really exciting. . . ” she says.

The group is studying the area because the CCZ，a huge and flat area of seabed，is known to have valuable minerals. The International Seabed Authority (ISA) is allowing the company UK Seabed Resources Ltd. to explore the area on the Pacific Ocean floor for mining. However，the ISA said the company must first complete a biological study of the area before it can begin mining for metals. So，the company employed Amon and her group.

Amon says that more than half of the animals they collected were completely new to science. Her group discovered not only new species，but new genera (动植物的属) of animals.

Biological oceanographer Paul Snelgrove says that finding new species in the deep ocean is common. But，he said，finding a new genus “is really great”.

Amon warns that if mining happens across the whole area，the ecosystem would be largely destroyed. But，she says，we will find the least damaging way to make mining possible.

“There is a sort of scientific push to try and slow things down a bit so that the science can be done before. . . so it can be done with the least influence possible. . . ” she says.

“It’s likely we are going to develop at least some parts of these deep ocean environments and do it in a way that’s going to minimize (最小化) our influence，”says Paul.
