Australian Defense Minister David Johnston says the search area is in extremely challenging environment. "Remember, this part of the world, this Southern Ocean, has shipwrecked many many sailors in our history in Western Austrailian. It is rough, sea state 7, you know, there are 20, 30 meter waves, it is very very dangerous, even for big Panamax-class ships." _______________________ 澳大利亚国防部长戴维表示,搜寻海域的环境极具挑战性."要知道,这里是世界的南半球海洋,在澳大利亚西部地区的历史上,曾经发生过许许多多起船只失事.粗略估计,海况达7级,也就是说会有20到30米高的波浪,即使对大型的巴拿马型船也是非常非常危险的."_____________________
