在南极海域畅游的妇女

纪录创造者考克斯3岁时就学会了游泳,12岁时她开始接受一个奥林匹克教练的训练,这位教练发现,考克斯耐力很好,后程比前程游得更快。她是一个出色的长距离游泳者,教练建议她在太平洋游泳,而不要在泳池中。在14岁时,她参加了一个游泳队,横渡了美国加利福尼亚的卡塔利那海峡,

发现 平脸琵琶鱼

近日，科学家在印度尼西亚海域发现了一种像人类一样眼朝前看、并且是爬行而非游动的平脸琵琶鱼，种种特征表明，这种拳头大小的鱼很可能代表着鱼类中的一个全新家族，之所以说它是琵琶鱼，是因为它的腿状胸鳍跟常见的琵琶鱼几乎一样不过．     

1980-2015年间北部湾海域热带气旋的变化及特征分析

由于地理特征独特,北部湾地区常年遭受热带气旋的影响。热带气旋引起的波浪灾害和风暴潮灾害对广西沿海经济、生活造成了巨大影响。本文采用中国气象局热带气旋最佳路径数据集,研究了1980—2015年间进入北部湾的热带气旋的变化及特征,对北部湾海域内热带气旋的频数、强度、持续时长、功耗指数等年际趋势变化进行分析。结果表明:1980—2015年,北部湾地区热带气旋的频数、持续时长呈波动减小趋势,其强度呈波动增加趋势,整体上功率耗散系数(Power Dissipation Index,PDI)的正效应大于负效应。本研究为北部湾地区的海洋防灾减灾提供了相关科学依据。     

厦门未来海岸在哪里

作为一个从事地球科学工作近40年的老科技工作者．提起笔来写这个题目时．心情是十分沉重的。近年来．作为厦门重点建设的工业区、产业带、海港航运物流园区、高级住宅区．海沧加大开发力度。沿九龙江口北岸建设大型深水码头．环西海域建设滨海大道、未来海岸和梦幻海岸高级住宅区等等。然而，依然采用继续向海域扩张．填海造陆的老方法。这势必进一步影响到厦门周边的海洋动力条件。     

Is there any amphidromic point of S2 constituent around the Natuna Islands in the southern South China Sea？

The discrepancies that if there is any amphidromic point of S2 constituent and its location if there is around the Natuna Islands in the southem South China Sea have suspended for a long time, however, there is always no convincing research to settle them up to now. The TOPEX/Poseidon and Jason-1 altimeters have been providing a long-term sea surface height data, which can be used to calculate the constants of tidal constituents along the satellite footprint with the harmonic analysis method. Based on more than 12 years altimetry data from T/P and Jason-1, the character of phase lags from harmonic analysis is used to identify if there is a S2 amphidromic point around the Natuna Islands. The result shows that there is no S2 amphidromic point instead of a nodal line of a standing wave, and the amplitude of S2 constituent is close to zero along the nodal line.     

科技时尚——海底大地震

2004年12月26日，圣诞节刚过，印尼苏门答腊岛北面海域发生强烈地震引发海啸，席卷东南亚多个国家，造成了数十万人死亡、重大的经济损失。惨痛的损失令人心惊，海底地震的惊人破坏力令人心悸。陆地上的地震我们已经通过媒体见得多了，但是，地震能够发生在深海而且还有这么大的危害人们可能不太了解。     

Distribution of diatoms in the water and surface sediments of southern South China Sea

The relationship of species and abundance between the diatoms in the water and sediments from the southern South China Sea （SCS） were discussed, and the key environmental controlling factors were also investigated. Studies show that the diatom abundance is high in both water and sediments in the southeast part of the southern SCS and the varying trend is similar, while in the northwest part, the abundance is low, and the varying trend is different. The dominant diatom species are Thalassionema nitzschioides and Nitzschia bicapitata in water, and T. nitzschioides and Chaetoceros messanensis in sediments. The diatom species of small size and thin shell in water are more than in the sediments, while the diatom species of large size and thick shell in water are less. The percentage of species T. nitzschioides is higher in water of southeast part than in that of northwest part, but it is similar in sediments of both areas. It is shown that the southwest monsoon is the important factor influencing diatom abundance and T. nitzschioides percentage, and when the southwest monsoon is well developed, the distribution of diatom abundance and T. nitzschioides percentage are consistent in both water and sediments of the study area.     

黄岩岛,中国如何应对菲律宾的挑衅

菲律宾挑起事端2012年4月8日,菲律宾海军的巡逻机在黄岩岛附近"发现"了12艘中国渔船。10日,菲海军出动该国最大的军舰"德尔皮拉尔"号,将中国渔船非法堵在黄岩岛潟湖内,试图抓扣在黄岩岛附近作业的中国渔民。菲海军士兵还登上中国渔船检查,并声称在一艘船上查获了"非法"捕捞的水产品。     

菲律宾染指中国黄岩岛回溯

在北纬15°08′、东经117°45′处,南中国海温暖的海浪在这里激起大片浪花,浪花飞溅处,露出成片的珊瑚礁石。阳光下,那些礁石射出炫目的金光。这就是我国在南海上的重要岛屿之一——黄岩岛。
