Allison Sherwood is chief scientist of seaweed study at the University of Hawaii.

艾莉森·舍伍德是夏威夷大学海藻研究的首席科学家。

She says in 2016 researchers from the National Oceanic and Atmospheric Administration discovered small clumps of a new alga they'd never seen before,

她说，2016年，美国国家海洋和大气管理局的研究人员发现了一种他们以前从没见过的小团块的新藻类，

this is a nuisance seaweed,

这是一种令人讨厌的海藻，

and we don't have a name for this alga,

我们没有这种藻类的名字，

that's rare,

这很少见，

you don't typically find something coming into an environment,and causing this level of alarm and simply not knowing what it is or where it might have come from,

通常不会发生这样的情况，即某些东西进入环境，并引起这种程度的恐慌，而你根本不知道它是什么，或者它可能来自哪里，

if something like this got back to Waikiki,

如果像这样的东西回到怀基基，

or anywhere in the main Hawaiian Islands,it would be a ecological disaster but also an economic disaster,

that threaten fish when they're most at risk as embryos or newborns spawn,

这会威胁到还在胚胎时期或者新生儿产卵时期的鱼类，

The reason for them being sensitive to temperature has to do with the provision of oxygen to these organisms.

鱼类对温度敏感的原因与氧气供应有关。

Professor Hans Otto Porter of the Helmholtz Centre for polar and marine research says,

赫尔姆霍兹极地和海洋研究中心的汉斯·奥托·波特教授表示，

the concern is rising temperatures forcing fish and oceans spanning the globe to find cooler waters to spawn,

令人担忧的是，气温上升会迫使鱼类跨越全球的海洋，以寻找更凉爽的水域产卵，

the species would have to move out of this area look for different sites,

that may be more suitable,

也许新的水域更加合适，

and would have to experience as of whether the site is suitable,based on other reasons- my food，availability and so forth.
