简介：在北半球从14个地点把重建和代理数据基于温度，这篇论文集中了于比较在北极和另外的区域之间的温度变化的周期包括大西洋，欧洲，中国，亚洲，和平，印度洋，并且美洲在到最后冰川的最大值的从最后Interstade的转变期间，从最后冰川的最大值到在Holocene和由单个光谱分析(SSA)的方法的小冰川期(LIA)的转变的megathermal时期结果证明在北极的环境变化在北美人并且更好很类似于那类似于亚洲，大西洋和太平洋，最不类似于印度洋和欧洲。温度的1500年的摆动在北极和欧洲两个都存在。

简介：健全生产的沙的主要元素作文第一次和稀土元素的元素(REE)和另外的选择元素被报导。在从在日本的Miyagi和Tottori的沙滩沙的稀土元素的元素集中被决定由联合正式就职，氩血浆spectrometry(ICPMS)到相对父母岩石描绘健全生产、沉默的沙的REE。健全生产的沙沙滩是很普通的并且在整个在在Miyagi的Japan:five沙滩并且2在区域与另外的沉默的沙沙滩在Tottori被选择。从Miyagi和Tottori的健全生产的沙和沉默的沙样品包含超过60wt%ofSiO_2并且主要由石英和长石组成。Miyagi沙样品被轻REE丰富和类似于本地来源沙岩的那些的完全使球粒状陨石正常化的模式描绘。然而，从在Miyagi的Miyatojima的所有沙样品显示出积极Eu异例，没在另外的沙显示出的一个典型特征从Miyagi取样。Tottori沙样品被高REE内容和显著积极Eu异例也描绘。包含lowerREE内容的沙由于高石英和长石内容。Miyatojima沙样品和Tottori沙样品有高REE内容并且由于长石的存在显示出显著积极Eu异例。最好的结果作为健全生产的沙和silents的类似的一项措施地质的方法和PrincipalComponent分析(PCA)用所有被获得并且。健全生产的沙和沉默的沙之间的差别从PCA结果被获得。

简介：重力的势能(GPE)来源和水池由于激动人心并且与西格马散开/移流联系的cabbeling被分析。GPE采购原料，这被显示出，水池太大，并且他们仔细没被连接到物理性质分发，例如温度，咸度和速度。尽管西格马坐标模型的最经常引用的优点是他们处理地形学的能力；GPE来源和水池的过多的数量由于激动人心并且与西格马散开/移流从我们的分析诊断了联系的cabbeling提出一个很严肃的问题侧面的散开/移流在西格马模仿了的方法是否协调模型，身体上是可接受的。在三个坐标的GPE来源和水池在他们的大小和模式是戏剧性地不同的。总的来说，以模仿侧面的旋涡散开和移流isopycnal坐标是最好的选择和西格马坐标是最糟。在西格马坐标的过多的GPE来源和水池的物理原因进一步在细节被探索。甚至在isopycnal坐标，然而，模拟能被与移流术语联系的数字错误基于Eulerian坐标污染。
