1·We have significantly improved our observing systems over recent years through particularly satellite systems but there is still major gaps particularly in the deep ocean.
我们近几年已大大改善了我们的观测系统，特别是借助卫星系统，但仍有很大的差距，尤其是在深海区域。
2·The atmospheric pressure and low temperatures found in the deep ocean environment should keep the liquid CO2 negatively buoyant , meaning it will sink rather than float.
大气压力和已经被发现的深海里的低温环境应该会保持CO2有负浮力，也就是它会在水里下沉而不是上浮。
3·Worldwide, this “biological carbon pump” transfers about 10 gigatonnes of carbon from the atmosphere to the deep ocean each year.
在全球范围内，这种“生物碳泵”每年从大气中向深海转移约10亿吨的碳。
4·The crabs are moving from the deep ocean, up the continental slope to the shallower shelf areas.
蟹类正在从深海沿大路斜坡向着较浅的大陆架区域移动。
5·Maybe not surprisingly, in the deep ocean, where it's mostly blue, the photo receptors tend to see blue light.
还有一个或许不足为奇的现象，在幽蓝的深海中，光受体倾向于“看”到蓝光。
