  • 简介:源于大气的碳的升起的层次,海洋使发酸成为了一个全球问题。它在海洋的有机体的发展,幸存,生长和生理学有重要影响。因此,一个高精确的传感器着急地被需要测量海水的pH。有0.25公里的一条直径的铱电线被用作底层,和红外/红外(哦)xpH电极被一出一步舞准备在在房间温度的一个LiOH答案的电气化学的方法。扫描电子显微镜(SEM)观察表明它与nanoscale粒子是涂的。在实验室测试,电极展出很有希望的pH回答,与理想的Nernst在测试pH的斜坡(56.14-59.52),快反应,好稳定性和长寿命缓冲答案。为海试用,四个pH电极和电极Ag/AgCl参考电极与一个白手起家的化学药品传感器,和将近70m的侧面察觉是综合的在Newport附近被实现港口,加利福尼亚在2015年8月3日。结果思考pH价值由传感器测量了,这离加CTD的海鸟911给的数据很靠近,与从的差别价值0.000075~0.064719。并且传感器显示出在0-40m水深度匹配度的一个更好的数据。另外,传感器的高精确和精确性使在海洋观察地里使用可能。

  • 简介:钻的井表明中新世的海洋的来源在Qiongdongnan盆的浅水区域摇的有机物许多与差的烃产生潜力是相对低的。然而,在一些钻深水区域结束的井到中央消沉带,有更好的有机物丰富的中新世的海洋的来源岩石和烃产生被发现了特征,它完成了基于geochemical的分析标准的更好的来源岩石。尽管在研究区域的深水区域没有探索的井,通过几口典型的探索的井的geochemical数据的比较分析分别地从在盆的浅水区域,在盆和地点的深海的区域的中央消沉带边缘深海在华南海盆钻中的1148个,它表明来源岩石的质量的趋势从三角洲逐渐地变得积极到bathyal环境,它然后是变得否定在de由于陆上的有机物输入的缺乏,在Qiongdongnan盆的中新世的海洋的来源岩石的重要控制因素是有机物的海洋生产率和保藏条件。元素地球化学数据显示paleoproductivity的趋势和有机物的保藏条件从浅区域作为水深度增加变得积极到bathyal区域结束到中央消沉带。必须在那里存在,这因此被推测在保藏有机物调节的中央消沉区域的高质量的来源岩石是好一些的。而且在理论,在在水深度的海洋的环境的缺氧地区4001000m,有机物的保藏条件因此很好正在形成高质量的海洋的来源岩石。产生推测,认为在Qiongdongnan盆的bathyal环境有高烃产生潜力来源岩石是合理的,特别在水深度4001000m。
