【文章內(nèi)容簡介】 se) I think thatamp。39。s got to be scaring a lot of animals away.
蒂伯龍潛艇使用的也是電動推進(jìn)器。它也相當(dāng)安靜，但是噪音要稍大一點(diǎn)。(稍大的呼呼聲噪音)但目前能潛到最深的那些遠(yuǎn)程遙控潛艇大多使用的是液壓驅(qū)動系統(tǒng)它們的聲音與溫塔娜潛艇的一樣。(大聲蜂鳴音噪音)我認(rèn)為它的聲音會嚇跑很多的動物。
So for the deep sea squid hunt, I proposedusing an optical lure attached to a camera platform with no thrusters, nomotors, just a batterypowered camera, and the only illumination ing fromred light thatamp。39。s invisible to most deepsea animals that are adapted to seeprimarily blue. Thatamp。39。s visible to our eye, but itamp。39。s the equivalent of infraredin the deep sea.
所以對于深海烏賊的探索，我建議使用光誘餌，將光源安裝到一個沒有推進(jìn)器、沒有發(fā)動機(jī)的相機(jī)平臺上，只有一個電池驅(qū)動的相機(jī)，并且唯一的光源來自紅光紅光是大部分的深海生物無法看到的它們適應(yīng)了只能主要看到藍(lán)色光。這對我們是可見的，但它相當(dāng)于深海中的紅外線。
So this camera platform, which we called the Medusa, couldjust be thrown off the back of the ship, attached to a float at the surfacewith over 2,000 feet of line, it would just float around passively carried bythe currents, and the only light visible to the animals in the deep would bethe blue light of the optical lure, which we called the electronic jellyfish,or ejelly, because it was designed to imitate the bioluminescent display ofthe mon deep sea jellyfish Atolla.
所以這個我們稱之為美杜沙的相機(jī)平臺可以直接從船后方扔到水中，平臺用長于610米的繩索連在船上，它會被動地由洋流驅(qū)使在周圍漂流，深海中動物們唯一可看見的光是光誘餌所發(fā)出的藍(lán)色光，我們將其稱之為電子水母，因?yàn)樗脑O(shè)計(jì)是模仿常見的深海棕色水母所發(fā)出的生物光。
Now, this pinwheel of light that the Atollaproduces is known as a bioluminescent burglar alarm and is a form of reason that the electronic jellyfish worked as a lure is not because giantsquid eat jellyfish, but itamp。39。s because this jellyfish only resorts to producingthis light when itamp。39。s being chewed on by a predator and its only hope for escapemay be to attract the attention of a larger predator that will attack itsattacker and thereby afford it an opportunity for escape. Itamp。39。s a scream forhelp, a lastditch attempt for escape, and a mon form of defense in the deepsea.
棕色水母所發(fā)出的這種旋轉(zhuǎn)光被認(rèn)為是一種生物光報(bào)警和一種防御形式。電子水母能成為誘餌的原因不是因?yàn)榫扌蜑踬\捕食水母，而是因?yàn)檫@
