海洋类院校专业硕士英语视听说课程研究

大连海洋大学从2009年开始海洋类专业硕士扩招,随着对外学术交流机会的增多,这些专业硕士研究生使用英语的机会逐渐增多.本文通过分析大连海洋大学专业硕士研究生英语视听说水平的现状,从优化课程设置、改进教学和教学方法方面研究海洋类院校专业硕士英语听说课程改革中能力培养的策略.并且,文中敦促建设研究生英语网络教学平台,从而帮助学生完成自主学习,科学有效地将课内外所学融会贯通,进而达到最理想的学习效果.     

Abrupt climate change：Debate or action

Global abrupt climate changes have been documented by various climate records, including ice cores, ocean sediment cores, lake sediment cores, cave deposits, loess deposits and pollen records. The climate system prefers to be in one of two stable states, i.e. interstadial or stadial conditions, but not in between. The transition between two states has an abrupt character. Abrupt climate changes are, in general, synchronous in the northern hemisphere and tropical regions. The timescale for abrupt climate changes can be as short as a decade. As the impacts may be potentially serious, we need to take actions such as reducing CO2 emissions to the atmosphere.     

Developmental modes of the Neoproterozoic-Lower Paleozoic marine hydrocarbon source rocks in China

Based on the researches on rock type, the mode of occurrence, diagnostic minerals and creatures, the sedimentary geochemistry and organic facies of Chinese marine source rocks from wells and outcrops, and on the research findings of developmental modes of foreign marine source rock, the authors consider that it is impossible to objectively make clear the formation mechanism of hydrocarbon source rock with high organic matter abundance by either single mode of preservation or high organic matter productivity. According to the Chinese geological features, the formation mechanism of the Neoproterozoic-Lower Paleozoic marine source rock is generalized into four modes, namely, thermal water activity-upwelling flow-anoxic; carbonate gentle slope-upwelling flow; xerothermic climate-brine euxinic milieu; and humid climate-retained euxinic milieu; as the Lower Cambrian undercompensation basin organic facies （the Tarim Basin, South China and southwestern margin of North China）, carbonate gentle lime mud bound organic facies （the Upper Ordovician in Tazhong region of the Tarim Basin and the Lower Silurian in the Upper Yangtze Platform）, the Middle Cambrian evaporation laggon organic facies （the Tarim Basin and the Upper Yangtze Platform）, enclosed undercompensation terrigenous bay organic facies （the Middle-Upper Ordovician in the west of the Tarim Basin, the Lower Silurian Long- maxi Formation in the Upper Yangtze platform）. Chinese marine sedimentations with lower organic matter abundance are generalized into two modes of consumption-dilution mode of open epicontinental sea and depletion-dilution mode of supercompensation basin.     

大海之下的科斯奎洞穴壁画

在海平面以下37米的地方发现一个曲折幽深的天然洞穴,也许算不上什么稀罕事。但是,假如你探入洞中却发现一个完整的史前人类的艺术宝库豁然现身于你眼前,这样的事恐怕就不多见了……     

地质的海洋

现在我们从飞机上可以轻易地看到地球表面的景观:茂密的森林、陡峭的峡谷,以及高耸的山脉等等,而且利用太空科技,我们甚至还可以看到火星上岩石广布的贫瘠表面。但是,对于自远古以来一直维系和决定着我们命运的海洋,我们却知之甚少。海洋对于我们来说,犹如藏在巨大蓝色水毯下的一个奥秘。 不过自上个世纪以来,借助海洋研究和海洋技术的进步,使我们能够前所未有地进入海洋,去一窥它的真实面貌。     

海洋光学遥感技术的发展和前沿

空间遥感与信息技术已经发展成为满足人类对海洋资源和环境不同尺度和不同层次连续、动态的信息需求的必要手段。海洋光学遥感在实施大范围海面瞬间信息监测、数年至几十年长序列全球海洋数据采集等方面，发挥了常规调查方法所不能替代的优势。从20世纪70年代开始，国际上发展了利用测量离水辐射率的原理，用现代的卫星遥感技术来实时监测海洋水色环境。80年代以来，我国对该项高技术也十分重视，并有了长足进展。文章回顾我国近20年来海洋光学遥感技术的发展；讨论了当前国家在海洋权益、防灾减灾、海洋资源管理和开发等方面的进一步需求；论述了该技术在环境监测应用导向下的前沿，如：高精度分析和定量化、高频率长序列监测和业务化趋向、多平台监测数据同化和核心技术合成。     

厦门—金门海域表层沉积物中HCHs,DDTs和PCBs的含量与分布

１９９５年１０月对厦门－金门海域表层沉积物中的有机氯农药（ＨＣＨｓ和ＤＤＴｓ）及多氯联苯（ＰＣＢｓ）的含量与分布进行调查研究，ＨＣＨｓ，ＤＤＴｓ和ＰＣＢｓ的含量范围分别为０．０３～０．４８ｍｇ／ｇ，２．９７～９．１６ｎｇ／ｇ和０．０２～０．１１ｎｇ／ｇ对其分布形式，残留水平以及组成等进行了评价与探讨，结果表明，厦门－金门海域基本上未受到ＨＣＨｓ和ＰＣＢｓ的污染，只受到ＤＤＴ的轻度污染，但是，ＤＤＴ     

卫星遥感影像在油污损害民事责任索赔中的应用

通过卫星遥感影像在两起海上油污索赔事例中的应用，显示了卫星影像的证据作用，使油污索赔更具科学性。
