Chinese scientists found a whale fall for the first time in the South China Sea this year. The whale fall ecosystem can stay in the deep ocean because of great pressure and cold temperature there.

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。

Engineers had spent days pumping heavy drilling fluid into the leaking well head on the ocean floor in a high-pressure bid to smother the gushing crude and ultimately seal the well with cement.

工程师们数日来一直向海底的泄漏油井泵入大量的钻探泥浆，希望用高压堵住喷涌的原油，最后用水泥封死油井。

The strength of that pressure may depend in part on the psychological impact of fresh discoveries about the diversity of ocean life.

Maarten Van Sluys, another member of the Brazilian victims' family association, said there was also concern about the condition of the black boxes after two years sitting in corrosive seawater under immense pressure, nearly 4km (2.5 miles) below the surface of the ocean.
