NASA captured 20 years of changing seasons in a striking new global map of the home planet.美国国家航空航天局(NASA)在一幅新的全球地图上捕获了二十年来的时节变化。The data visualization shows Earths fluctuations as seen from space.这一数据可视化展览了在外太空中看到的地球上的起伏变化。The polar ice caps and snow cover are shown ebbing and flowing with the seasons. The varying ocean shades of blue, green, red and purple depict the abundance – or lack – of undersea life.不言而喻,北极冰盖和降雪都随时节的变化而变化。

深蓝色、翠绿色、鲜红色和蓝紫色的各有不同海洋黑影,描绘了海洋世界的比较丰富或缺乏。Its like watching the Earth breathe. Its really remarkable, said NASA oceanographer Jeremy Werdell, who took part in the project.参与了这一新项目的NASA海洋专家学者杰里米·维尔德尔答复:“这就看上去在看地球大便,这了解很简直。”Two decades- from September 1997 to this past September – are crunched into 2.5 minutes of viewing.从1997年10月到2020年10月的这二十年,被传送为这2分半钟的影象。

Werdell finds the imagery mesmerizing. Its like all of my senses are being transported into space, and then you can compress time and rewind it, and just continually watch this kind of visualization, he said.维尔德尔称作,这一段影象过度让人著迷了。他讲到:“如同将我全部觉得传送至宇宙空间中,随后你能随意快放、推翻携带,并反复地欣赏这类数据可视化的全过程。”Werdell said the visualization shows spring coming earlier and autumn lasting longer in the Northern Hemisphere. Also noticeable to him is the receding of the Arctic ice caps over time – and, though less obvious, the Antarctic, too.维尔德尔答复,图象说明北半球地图的春季远比更为早于,秋季看起来更长。某种意义特别注意的是,北极圈的冰盖已经逐渐消溶,南极洲也是这一状况,尽管但是于明显。

On the sea side, Werdell was struck by this hugely productive bloom of biology that exploded in the Pacific along the equator from 1997 to 1998 — when a water-warming El Nino merged into cooling La Nina. This algae bloom is evident by a line of bright green.在海洋层面,“这一巨大的微生物昌盛”让维尔德尔倍感气愤–从1997年到一九九八年,在地球赤道周边的中国太平洋突然越来越激烈–那时候的厄尔尼诺暧流与拉尼娜寒潮相互之间结合。根据那一条显眼的绿带很明显的显出藻类的猛增。In considerably smaller Lake Erie, more and more contaminating algae blooms are apparent – appearing red and yellow.较为经营规模小的伊利湖,其更为多的环境污染藻类植物的很多繁殖不言而喻,展现红色和黄色。

All this data can provide resources for policymakers as well as commercial fishermen and many others, according to Werdell.维尔德尔强调,这种数据信息能够给现行政策实施者、商业服务打捞者及其别人获得一些信息内容。
