This report concerns the first ever detailed map-based assessment of potential threats to coral reef ecosystems around the world. "Reefs at Risk" draws on 14 data sets (including maps of landcover ports settlements and shipping lanes) information on 800 sites known to be degraded by people and...
Definition Reefs at Risk is a series of publications, produced by the World Resources Institute (WRI) in collaboration with partner organizations, that provides detailed spatial analyses of threats to the world's coral reefs. Reefs at Risk: A Map-Based Indicator of Threats to the World's Coral...
Coral reefs (珊瑚礁) are among the most productive ecosystems in the world. They're also in serious danger—climate change and other threats are killing them off. But researchers have come up with an invention they think could help the reefs: 3D-printed corals. ...

4.C.细节理解题.根据前文"Coral reefs are often described as undersea forests, but they are declining far more quickly than the Amazon rainforests珊瑚礁常被描述为海底森林,但它们的消失速度比亚马逊雨林要快得多".可知此处应填"珊瑚礁可能是第一批被气候危机摧毁的生态系统".故选C. 本文是一篇选句填空...
With overwhelming evidence that much of Earth's reefs are in decline, our need for large-scale, repeatable assessments of reefs has never been so great. Fortunately, the last two decades have seen a rapid expansion in the ability for remote sensing to map and monitor the coral reef ecosystem...
larger deep-sea reefs will be discovered in the future since only about 25 percent of the world's ocean floor has been mapped in 3D. Only 50 percent of U.S. offshore waters have been mapped. Maps of the ocean floor are created using high-technology sound equipment, called sonar, on ...
The datasets enable the team to mark the exact locations of the reefs on the map. ▲ . It is updated every two weeks, together with the position information from the GPS system. It allows experts to see real-time information about reefs and work on coral science activities. The ACA has ...
