根据第二段第二句“Scientiststrytolearnmoreabouthowthesealionsusedifferentpartsoftheseafloortogetfood.(科学家试图更多地了解海狮是如何利用海底的不同区域来获取食物的。)”可知,科学家做这个研究是为了了解海狮和海底的情况。结合选项,A选项的意思是“去测试海有多深”;B选项的意思是“去拯救所有濒危的动物”;C...
Plastic pollution on the seafloor is far from the only problem in the oceans. As plastic degrades over time, itbreaks into tiny microparticlesthat can contaminate the entire ocean food chain, from krill to baleen whales. That’s not to mention the large chunks of plastic debris and—most imp...
The part of the ocean that is deeper than just 200 meters is considered the “deep sea.” However, some parts of the oceans go up to several kilometres. But what is the deepest part of the ocean exactly? Scientifically speaking, the deepest part of the ocean refers to the maximum depth ...
no one wants to foot the bill. One method explored in the past decade might now be a step closer(8)___becoming practical. The process (9)___(involve) pumping CO2 carried through the air down into methane hydrates (甲烷水合物) right under the seafloor, where the gas will be(10)__...
all our advanced technology, we've only mapped around 26% of the seafloor. It's also good to remember that we understand so little of what has been mapped that we're still stumbling upon paradigm shifters likethe discovery of dark oxygenandfinding life in strange places in the Pacific ...
Scientists believe ocean ridges are formed when molten rock, or magma, escapes from Earth's interior to form the seafloor, a process known as seafloor spreading. Rifts may be the specific parts of the ridges where the magma escapes.

covered areas tend to be enriched in biomass and diversity relative to sediment-starved areas. The results suggest that fluid discharged through sediments to the seafloor are strongly affected by subsurface microbial processes and result in increased biomass and diversity of the seafloor animal community...
Rocket engine parts from the Apollo moonshots have arrived at Seattle's Museum of Flight, and Amazon billionaire Jeff Bezos was on the welcoming committee.
