[:ja]NASAのOperation IceBridgeのリサーチフライトから撮影されたグリーンランドのピーターマン氷河です。相当程度氷が融解する夏までまだ遠く、寒暖差により、氷床は凍ったり解けたりします。
前日のピーターマン・ポンドは氷が解けていました。
グリーンランドは大部分が北極圏に属し、全島の約80%以上は氷床と万年雪に覆われています。巨大なフィヨルドが多く、氷の厚さは3,000m以上に達する所もあり、居住区は沿岸部に限られます。主要産業は漁業とその加工業で、輸出の87%を占め、特にエビはその半分以上を占めています。グリーンランドという名前は、982年頃、ノルウェーの探検家である赤毛のエイリークにより命名されました。エイリークはグリーンランド上陸より前、アイスランドを発見していましたが、彼が命名したアイスランドは、その名称故に入植希望者が現れず、この地に入植希望者が多数現れることを願い、「緑の島」と名付けました。

[Earthview Wonders] No.768: Ice of Greenland🇬🇱
NASA’s research flight on Operation IceBridge captured Petermann Glacier, Greenland. It won’t be until summertime that a significant amount of melt shows up across the Greenland Ice Sheet. The image on April 16 shows part of a frozen meltwater lake while the one on April 17 shows the lake is well frozen and covered with snow again.
The pond on the previous day had meltwater.
Greenland is the world’s largest island of which three-quarters of the land is covered by the only permanent ice sheet outside Antarctica. The Greenlandic economy is highly dependent on fishing. Fishing accounts for more than 90% of Greenland’s exports, and the shrimp and fish industry is by far the largest income earner. In 982, after finding a habitable area and settling there, the Norwegian-born Icelander Erik the Red named it “Greenland”, supposedly in the hope that the pleasant name would attract settlers.
