              HIGH-TECH EAVESDROPPING ON THE GANGES RIVER DOLPHIN SONAR

               SIGNALS HOLD CLUES THAT COULD SAVE AN ENDANGERED SPECIES

      The Ganges river dolphin is one of only two remaining freshwater dolphin species on Earth. But pollution, fishing, and dams threaten to wipe it out entirely.

      So acoustical engineer Harumi Sugimatsu and her team have deployed an experimental sonar monitoring system just under the surface of the murky water. The hope is to track the dolphins by the high-frequency clicks they use to navigate and hunt. By eavesdropping on their underwater lives, Sugimatsu believes she can gather data about their behavior and geographical range—data that conservationists can use in their struggle to keep the species from going extinct.

What's the meaning of the underlined word in the following sentence: “(…) her team have deployed an experimental sonar monitoring system just under the surface of the murky water”?

  • Questão pode ser resolvida por meio de inferência. Se estamos falando da água do rio Ganges, um dos mais poluídos do mundo, é claro que a água será Escura (darkened e dusky são sinônimos e ambos significam 'escuro')
