简介:热流动在2012在第5中国国家北极远征期间在洛莫诺索夫·理兹上被测量。为了导出时间温度,弯,抵抗力数据被resistivitytemperature节目转变到温度。直接的读和线性回归方法被用来计算平衡温度,它是对在沉积的探针的深度的regressed导出地热的坡度。然后,热流动作为地热的坡度的产品和沉积的热电导率被计算。热流动价值根据二个方法是类似的(即,67.27mW/m2和63.99mW/m2,分别地)。结果与大小在邻近的地点执行了一致。热流动模型预言的洛莫诺索夫·理兹的年龄是62妈,它根据山脉在大约60妈与欧亚大陆被分开的推理。

简介:在海洋的上面的层的热分布被使用各种各样的典型因素学习了,一些重要低频率摆动(LFO)已经被发现并且确定。在这篇论文,“一个海区域的热中心”与一个简单方法被定义。然后全球海洋的上面的层的温度数据集(从在to400m下面的表面,1955-2003)被分析检测可能的LFO。不仅一些带的LFO,早被报导,而且垂直、南方的热分发的一些强壮的LFO被检测。类似的垂直摆动模式能在太平洋,大西洋和印度洋被发现,这应该被注意。从一些初步的研究的结果证明垂直LFO可能被太阳的发光异例引起。这研究可以帮助在全球海洋揭示一些未知动态过程并且可以也有益于另外的相关研究。
