全球珊瑚礁全景地图绘制完毕
Researchers have completed a comprehensive online map of the world’s coral reefs by using more than 2 million satellite images from across the globe.
研究人员利用来自全球各地的200多万张卫星图像，完成了一份全球珊瑚礁的全面在线地图。
The Allen Coral Atlas, named after late Microsoft co-founder Paul Allen, will act as a reference for reef conservation, marine planning and coral science as researchers try to save these fragile ecosystems that are being lost to climate change.艾伦珊瑚图集以已故微软联合创始人保罗·艾伦的名字命名，将作为珊瑚礁保护、海洋规划和珊瑚科学的参考，研究人员试图拯救这些因气候变化而消失的脆弱生态系统。
The group announced completion of the atlas Wednesday and said it is the first global, high-resolution map of its kind.
该组织周三宣布完成了该地图集，并表示这是首个全球高分辨率的此类地图。
It gives users the ability to see detailed information about local reefs, including different types of submarine structure like sand, rocks, seagrass and, of course, coral.
它让用户能够看到当地珊瑚礁的详细信息，包括不同类型的海底结构，如沙子、岩石、海草，当然还有珊瑚。
The maps, which include areas up to 50 feet (15 meters) deep, are being used to inform policy decisions about marine protected areas, spatial planning for infrastructure such as docks and seawalls and upcoming coral restoration projects.
这些地图包括深达50英尺(15米)的区域，被用来为海洋保护区的政策决策、码头和海堤等基础设施的空间规划以及即将到来的珊瑚恢复项目提供信息。
“Our biggest contribution in this achievement is that we have a uniform mapping of the entire coral reef biome,” said Greg Asner, managing director of the Atlas and director of Arizona State University's Center for Global Discovery and Conservation.
“我们对这一成就的最大贡献是，我们有了整个珊瑚礁生物群落的统一地图，”阿特拉斯的常务董事兼亚利桑那州立大学全球发现和保护中心主任格雷格·阿斯纳说。
Asner said they relied on a network of hundreds of field contributors who gave them local information about reefs so that they could program their satellites and software to focus on the right areas.
阿斯纳说，他们依靠的是一个由数百名现场贡献者组成的网络，他们向他们提供有关珊瑚礁的当地信息，这样他们就可以对卫星和软件进行编程，以专注于正确的区域。
“And that lets us bring the playing field up to a level where decisions can be made at a bigger scale because so far decisions have been super localized," Asner said.
阿斯纳说:“这让我们能够将竞争环境提升到一个更高的水平，在那里我们可以更大规模地做出决策，因为到目前为止，决策都是很局部区域化的。”
"If you don’t know what you’ve got more uniformly, how would the U.N. ever play a real role? How would a government that has an archipelago with 500 islands make a uniform decision?”
他说:“如果你不知道你得到的是什么，那么联合国怎么能发挥真正的作用呢?一个拥有500个岛屿的群岛政府如何做出统一的决定?”
The atlas also includes a coral bleaching monitor to check for corals that are stressed due to global warming and other factors.
该地图集还包括一个珊瑚白化监视器，以检查由于全球变暖和其他因素而受到压力的珊瑚。
Asner said about three quarters of the world's reefs had not previously been mapped in this kind of in-depth way, and many not at all.
阿斯纳说，世界上大约四分之三的珊瑚礁以前从未以这种深入的方式绘制过地图，很多根本没有。
The project began in 2017 when Allen's company, Vulcan Inc., was working with Ruth Gates, a Hawaii researcher whose idea of creating “ super coral ” for reef restoration was funded by the philanthropic foundation.
该项目始于2017年，当时艾伦的瓦肯公司Vulcan Inc.正在与夏威夷研究员露丝·盖茨合作，后者为珊瑚礁修复创造“超级珊瑚”的想法得到了该慈善基金会的资助。
Gates and Vulcan brought in Asner because of his work with the Global Airborne Observatory that had been mapping reefs in Hawaii at the time.
盖茨和瓦肯公司请来了阿斯纳，因为他在全球航空天文台工作，当时该天文台正在夏威夷绘制珊瑚礁地图。
Allen, who said he wanted to help save the world's coral reefs, liked the idea of using technology to visualize data, so Gates connected the group with a satellite company called Planet, and Allen funded the project for about $9 million.
艾伦说他想帮助拯救世界上的珊瑚礁，他喜欢用技术来可视化数据的想法，所以盖茨将这个组织与一家名为Planet的卫星公司联系起来，艾伦为这个项目提供了大约900万美元的资金。
The University of Queensland in Australia used artificial intelligence technology and local reference data to generate the layers on the atlas.
澳大利亚昆士兰大学使用人工智能技术和当地参考数据生成地图集上的层次。
Anyone can view the maps for free online.
任何人都可以在网上免费查看地图。
Both Allen and Gates passed away in 2018, leaving Asner and others to carry on their work.
艾伦和盖茨都于2018年去世，留下阿斯纳和其他人继续他们的工作。
"Ruth would be so pleased, wouldn’t she?" Asner said.
“露丝要是能看到，她肯定会很开心的，不是吗？”阿斯纳说道。
“She would just be tickled that this is really happening.”
“她肯定很高兴看到我们终于完成了。”
