马里亚纳海沟是目前所知地球上最深的海沟,也被称为“地球的伤疤”。近日,“蛟龙”号载人潜水器5天中,3次潜入马里亚纳海沟6000米级大深度,并带回了15.4公斤玄武岩样品,16升近底海水和7管沉积物样品,以及海参、海葵样品各1只。值得一提的是,本次带回的海参样品,是利用生物原位固定装置成功采集并固定的,比较完整地保存了生物原位RNA信息,这对于研究生物对深渊极端环境的适应机制非常有帮助。
The Mariana Trench is by far the deepest trench on the planet known as “the Scar of the Earth.” Recently, “dragon ” manned submersible 5 days, 3 times into the Mariana Trench 6,000 meters deep, and brought back 15.4 kg of basalt samples, 16 liters of seawater and seven sediment samples, And sea cucumber, sea anemone samples of a. It is worth mentioning that this sample of sea cucumber taken back is successfully collected and immobilized by the biological in situ fixator, which completely preserves the biological RNA in situ, which is very suitable for the study of the adaptation mechanism of the living creature to the extreme environment of the abyss helpful.
