全球海洋的升温和酸化已经足够令人忧心忡忡,但根据国际海洋状态研究计划署日前公布的报告,海水缺氧可能会给已岌岌可危的海洋生态环境再来一击。研究者指出,到本世纪末,海水的含氧量可能减少7%。海水失氧的部分原因在于温暖海水本身所容纳的氧较少,与此同时,由于海洋表面升温幅度最大,使得温暖海水更易浮在上层,不易与下层的凉爽海水混合,从而令深层海水缺氧问题变得更严重。研究者警告说,虽然酸
The warming and acidification of the global oceans have been troubling enough, but hypoxia from the sea may give a second blow to the precarious marine environment, according to a report recently released by the International Marine States Research Agency. Researchers point out that by the end of this century, the oxygen content of seawater may be reduced by 7%. Part of the reason for sea water anaerobic is that the warm sea water itself contains less oxygen. At the same time, warm sea water is more likely to float on the upper layer and less likely to mix with the lower cool seawater, resulting in deep sea water anoxic The problem has become more serious. The researchers warned that although acid
