    VOA慢速英语:英国领导的研究小组从印度洋进行历史性的广播

    Source: 恒星英语学习网    2019-03-13   English BBS   Favorite  

    A British-led research team has sent its first live, television quality video transmission from a two-person submersible vehicle.

    Team members entered two submersibles, which slowly went down into waters off the coast of the Seychelles on Tuesday. The aim of the project is to document changes taking place in the Indian Ocean.

    Heavy seasonal storms and strong underwater currents continued to present problems at greater depths during the study.

    The AP used optical video techniques to transmit the pictures through the waves by using the blue part of the electromagnetic spectrum.

    Before now, real-time video transmissions from the world's deep oceans were livestreams. This means they were sent from unmanned subsea vehicles that were operated on land. The video was sent through fixed fiber-optic wiring.

    The new transmission uses the latest wireless technology. The signal came from 60 meters down.

    The Associated Press is the only news agency working with British scientists from the Nekton research team on its deep-sea project. The researchers hope to open up the secrets of the Indian Ocean, one of the world's least explored areas.

    The team of scientists is gathering information to help policy-makers to create environmental protection measures.

    Oliver Steeds is the director of the study. He said the experience of battling the waves shows the need to expand scientific knowledge of the waters off the Seychelles.

    "The problem is, when it comes to this place, when it came to the currents, the most recent current records are from 1882," he said.

    The study is expected to last seven weeks, until April 19.
