我在哪里看到过有人有人尝试将“小”冰山巨头拖船使用石油钻塔。我认为如果冰山可以移动,为什么不把它向北美元也许 纬度以上的“打破”了。也许可以被锚定。这是可行的吗?

的一些背景知识。拖曳冰冰山的想法提供淡水来源在干燥气候区在1970年代首次提出了周,坎贝尔(1973)和霍特和奥斯特兰德(1973)。这引发了兴趣,导致一些研究发表在会议(Husseiny, 1980;IGS, 1980)。的重点工作是男子气概的冰的浪费在交通当然拖冰的技术方面。然而,主要的问题担忧冰冰山在运输的完整性。冰山的冰力学仍知之甚少,众所周知,冰山逐渐分解。这是如何影响海洋膨胀和其他力在冰山下拖仍在调查(见大量的出版物特别是< a href = " http://www.igsoc.org/journal/ " >杂志Glacology < / >和< a href = " http://www.igsoc.org/annals/ " >上冰川学< / >)。然而,想法不被遗忘,更提出了可行的技术解决方案(例如< a href = " http://www.fastcompany.com/1755444/watch-tugboat-drag-arctic-iceberg-parched-people-half-world-away-video " >快公司< / >。所以在金融方面的过程可能是可计算的,冰的力量冰山,作用在他们身上下的大海和拖拖之前需要更多的研究将成为现实。 这是合法的问题。 Who owns the ice? and also how can towing ice berg across busy shipping lines be safe, particularly in the event of a break-up in mid-ocean.

To respond to your specific question on towing northward and anchoring: The towing in any direction is subject to the same issues as described above. Anchoring, the ice bergs will melt and degrade over time so that moorings will continually have to be renewed. Most ice bergs in the north will go through at least one cycle of being caught in seasonal sea ice but eventually will be set free to follow ocean currents in whatever direction they move locally. Since the ocean water will carry some heat, it will not matter where the ice berg is located, it will slowly melt. On top of that is the issue of disintegration since melting will change the shape of the berg and hence its stability and centre of gravity causing stresses within the block to alter.

If one takes a longer-term perspective and ignores the practicalities (incl. costs), moving ice to a place where it melts slower would momentarily decrease the contribution but eventually one would reach a new equilibrium where the same rate of melt water will be contributed and the temporary benefit will be lost. So apart from being highly impractical from all aspects, the longer-term benefits will be nil.
