海洋中有一片绿色“草原”1492年8月,决心开辟通向印度航线的哥伦布率领三艘帆船离开西班牙巴塞罗那港,雄心勃勃地向大西洋驶去。哥伦布船队经过一个多月的航行,四周仍是天水一色,无边无垠,船员不免有些焦躁不安,悲观失望。这时,突然在远方出现一片绿色的“草原”。“上帝,终于到达大陆了!”哥伦布和他的船员都兴奋得欢呼起来。他们重振旗鼓,飞驶前进。可是,当他们驶近“草地”时,便大失所望了。原来,它根本不是什么陆地,而是漂浮在水面上的大片“海草”。渐渐地,水草越来越密,三艘帆船很快被水草团团围住,犹如在大草原中迷路的小羊羔,惊恐地寻找着出路。“啊,这是什么鬼地方!”只见团团的海草密密地覆盖着整个海面,海草上冒着一串串海泡,好像挂着一串串小葡萄似的,上面还栖息着小鱼、小虾、小蟹、章鱼和其他生物。令人惊奇的是,这些小东西都有着和海草一样的颜色,几乎和海草无法分辨。船随着海草密度的增加越行越慢,最后竟像陷入泥潭一样不能动弹。没有完全丧失信心的航海探险者们乐观地猜测,在海草附近可能会有陆地。于是,他们用火炮发射测深锤测量水深,哪料到,几百米长 There was a green “grassland” in the oceans. In August 1492, Columbus, determined to open up the route to India, led three sailing boats out of the port of Barcelona, ​​Spain, and drove ambitiously toward the Atlantic Ocean. Columbus fleet after more than a month of voyage, is still surrounded by Tianshui, boundless, inevitably some of the crew restless, pessimistic disappointment. At this moment, a green “grassland” suddenly appeared in the distance. “God, finally reached the mainland!” Columbus and his crew were cheered excitedly. They revived and flew forward. However, they were greatly disappointed as they approached Grassland. It turned out that it is not what land, but floating in the water on the blockbuster “seaweed.” Gradually, water and plants are getting closer and closer. Three sailboats are quickly surrounded by water and grass, like little lambs lost in the prairie, looking for a way out of fear. “Ah, what a hell is this place!” I saw the seaweed in a circle closely covering the entire sea surface, and the seagrass risked a string of sea-bubbles as if hanging a string of small grapes that still inhabit Fish, shrimp, crabs, octopuses and other creatures. Surprisingly, these little things have the same color as seagrass, almost inseparable from the seagrass. As the density of seagrass increases more and more slowly, it finally can not move like a quagmire. Nautical explorers without total loss of confidence are optimistically guessing that there may be land near the seagrass. As a result, they measured the depth of water with a cannon firing sounder, where expected, a few hundred meters long
