Researchers are using an underwater drone (无人机) to get information on carbon dioxide (CO₂) levels in the ocean. It is believed to be the first time that such a device (装置) has been used purposely to test CO₂ levels.
The device, which the team also calls a glider, is designed to go down to 1,000 meters in deep ocean areas and can operate for weeks at a time.
The purpose of the research is to provide scientists with data (数据) about how climate change is influencing the ocean’s chemistry. The self-swimming drone was placed in the Gulf of Alaska this spring. Reporters from The Associated Press recently joined researchers on a boat in Alaska’s Resurrection Bay to see the drone in action.
The team says the project could be a major step forward in measuring(测量) the environmental health of oceans. The scientists are most interested in levels of ocean acidification(酸性). This happens when CO₂ emissions(排放) in the air make their way into the ocean. Ocean acidification can harm or kill some kinds of sea life.
Scientists have connected CO₂ emissions with global(全球) warming caused by human activities.
In a way, oceans have given humans a helping hand by taking in(吸收) some of the CO₂. If there were no oceans’ uptake, there would be much more CO₂ in the air. This would trap more of the sun’s heat and further warm the Earth.
“But the problem now is that the ocean is changing its chemistry because of this uptake,” said team member Claudine Hauri.
One of the best ways to measure ocean acidification is to collect CO₂ measurements. Until now, these collections were mostly done from ships or with devices floating at the ocean surface or on the ocean floor.

Jessie felt her life so boring one summer day. She was tired of watching TV, she read all her books, and her friends were on vacation. She wanted something different to do. Suddenly, she saw the lawn mower(割草机) sitting in the yard.
“Mom,” she shouted, “I think I will mow the lawn.” Her mom ran into the yard and said, “Oh no, you don’t. You’re too young to mow the law.”
“I’m fourteen years old and know how to do it,” Jessie said. “Besides, it would help Dad out, and he won’t have to worry about it over the weekend.”
Mom thought for a while and then decided to let Jessie give it a try. After all, she was home and would keep an eye on her. Jessie already knew how to start the lawn mower from watching her dad.

If you want to travel with a partner, you may ask for one on the Internet. There are some tips about how to choose a right partner on the Internet:
Unluckily, you can’t ask a person if he has a good feeling. If you ask, everyone will tell you that they do! It is important that you have to get to know your travel partner to find out what kind of feeling he really has.

Talk about the hotel you would like to stay in. See if you have the same habit of spending holidays. This is such a quick way to find a partner.
