Flying over northern Greenland, Greene was able to photograph the ice sheet from the aircraft window. This image led to the discovery of something buried under ice.<\/p>\n<section class=\"fake-br-for-article-body\"\/>\n<p>NASA Jet Propulsion Laboratory (JPL) cryospheric scientist Alex Gardner reported, \u201cWe were looking for the bed of the ice and out pops Camp Century. We didn\u2019t know what it was at first.\u201d<\/p>\n<section class=\"fake-br-for-article-body\"\/>\n<section class=\"hide-for-premium\">  <\/section>\n<section class=\"fake-br-for-article-body\"\/>\n<p>Camp Century, the \u201ccity under the ice,\u201d is a notable Cold War site. The military base was constructed in 1959 by the US Army Corps of Engineers. They created a tunnel network within this layer of the ice sheet, but it was abandoned in 1967, leading to its disguise under layers of snow build-up. The facility now lies 100 feet below the surface.<\/p>\n<section class=\"fake-br-for-article-body\"\/>\n<figure class=\"article-image-in-body\"><figcaption class=\"article-image-caption article-image-credit\" style=\"max-width:100%;height:auto;\"> Constructing the trenches at Camp Century, Greenland. (credit: Wikimedia Commons)<\/figcaption><\/figure>\n<\/p>\n<p>Scientists used radar to map the ice surface by sending out radio waves and testing their reflection time. While past airborne surveys were able to detect some signs of Camp Century under the ice, the April flights were better suited for the task.<\/p>\n<section class=\"fake-br-for-article-body\"\/>\n<p>NASA\u2019s UAVSAR (Uninhabited Aerial Vehicle Synthetic Aperture Radar) was mounted onto the modern aircrafts, allowing the vehicles to produce more dimensional maps.<\/p>\n<section class=\"fake-br-for-article-body\"\/>\n<h3>Making history<\/h3>\n<p>Greene, who also works at the JPL, explained, \u201cIn the new data, individual structures in the secret city are visible in a way that they\u2019ve never been seen before.\u201d<\/p>\n<section class=\"fake-br-for-article-body\"\/>\n<section class=\"hide-for-premium\"> <\/section>\n<\/p>\n<p>Despite providing crucial information, the added dimension in newer scans also poses challenges in interpreting the images. Scientists have used maps acquired through radars to estimate when melting or thinning of ice might expose the camp again and whether any remaining radioactive or chemical waste is buried with it.<\/p>\n<section class=\"fake-br-for-article-body\"\/>\n<p>Greene and Gardner did not even intend to photograph Camp Century but rather \u201cto calibrate, validate, and understand the capabilities and limitations of UAVSAR for mapping the ice sheet\u2019s internal layers and the ice-bed interface,\u201d as Greene explained. \u201cWithout detailed knowledge of ice thickness, it is impossible to know how the ice sheets will respond \u2026 limiting our ability to project rates of sea level rise,\u201d reported Gardner.\u00a0<\/p>\n<section class=\"fake-br-for-article-body\"\/>\n<p>The test flights conducted in April are opening a next-generation ability for mapping in Greenland, Antarctica, and other uncharted territories.&#13;<\/p>\n<section>&#13;<br \/>\n\t\t\t\t\t&#13;<br \/>\n\t\t\t\t<\/section>\n<p>&#13;\n\t\t\t<\/p>\n<\/div>\n<p><script>\n  !function(f,b,e,v,n,t,s)\n  {if(f.fbq)return;n=f.fbq=function(){n.callMethod?\n  n.callMethod.apply(n,arguments):n.queue.push(arguments)};\n  if(!f._fbq)f._fbq=n;n.push=n;n.loaded=!0;n.version='2.0';\n  n.queue=[];t=b.createElement(e);t.async=!0;\n  t.src=v;s=b.getElementsByTagName(e)[0];\n  s.parentNode.insertBefore(t,s)}(window, document,'script',\n  'https:\/\/connect.facebook.net\/en_US\/fbevents.js');\n  fbq('init', '1730128020581377');\n  fbq('track', 'PageView');\n<\/script><br \/>\n<br \/><script async src=\"https:\/\/pagead2.googlesyndication.com\/pagead\/js\/adsbygoogle.js?client=ca-pub-3711241968723425\"\r\n     crossorigin=\"anonymous\"><\/script>\r\n<ins class=\"adsbygoogle\"\r\n     style=\"display:block\"\r\n     data-ad-format=\"fluid\"\r\n     data-ad-layout-key=\"-fb+5w+4e-db+86\"\r\n     data-ad-client=\"ca-pub-3711241968723425\"\r\n     data-ad-slot=\"7910942971\"><\/ins>\r\n<script>\r\n     (adsbygoogle = window.adsbygoogle || []).push({});\r\n<\/script><br \/>\n<br \/><div data-type=\"_mgwidget\" data-widget-id=\"1660802\">\r\n<\/div>\r\n<script>(function(w,q){w[q]=w[q]||[];w[q].push([\"_mgc.load\"])})(window,\"_mgq\");\r\n<\/script>\r\n<br \/>\n<br \/><a href=\"https:\/\/www.jpost.com\/international\/article-831194\">Source link <\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>&#13; A NASA scientist uncovered a Cold War military base under ice in Greenland this April, as reported by NASA\u2019s Earth Observatory on Monday.
