Workshop Support: Establishing Data Reporting Requirements and Data Archiving for U-Series Dating

这项奖励将支持为期两天的研讨会，以建立U系列测年方法的数据报告要求和程序。这项工作是在EarthChem和EARTHTIME项目之间进行的，并得到了英国地质调查局(BGS)的一些赞助。研讨会将于2010年6月21日和22日在英国诺丁汉的英国地质调查局举行。主要的技术挑战是确定所需的报告要求，包括具体的数据和元数据项目。还将确定可选要求。此外，我们将探索通过使用XML通信或Web表单交互的数据简化包将数据提交到地球化学的Geochron数据库的软件方法。U系列测年方法依赖于铀衰变的各种中间但仍具有放射性的子产物达到稳定构型所需的时间。首先，子体元素不存在平衡浓度？这是在几十万年的时间里建立起来的。这种方法在确定现代火山和海洋沉积物的年龄方面非常有效，特别是在不到50万年前的样品上。讲习班的目的是使成果报告完整和透明。这样，来自不同实验室和/或使用不同程序和设备的样本可以在平等的基础上进行比较。此外，研讨会应建立一种报告这些数据并最终被包括研究人员、学生和其他感兴趣的个人在内的各种用户发现的方法。通过这种方式，可以更好地理解火山喷发、海平面和气候变化等事件，以及无数其他最近的地质现象，并将其与相关数据相结合。

This award will support a two-day workshop to establish data reporting requirements and procedures for the U-series dating method. The effort is between the EarthChem and EARTHTIME projects, and has some sponsorship from the British Geological Survey (BGS). The workshop will be held on June 21 and 22, 2010, at the BGS in Nottingham, UK. The main technical challenges are to establish required reporting requirements including specific data and metadata items. Optional requirements will also be identified. In addition, we will explore software approaches via data reduction packages using XML communication or web form interaction to submit data to the Geochron database at EarthChem.The U-series dating method relies on the time it takes the various intermediate but still radioactive daughter products of Uranium decay to reach a stable configuration. At first, the daughter elements are not present in equilibrium concentration ? this is established over a period of a few hundred thousand years. The method is very powerful for establishing ages of recent volcanic and marine deposits, particularly on samples less than around half a million years old. The workshop is to make the reporting of results complete and transparent. In this way, samples from different labs and/or using different procedures and equipment can be compared on an equal basis. In addition, the workshop should establish a way for these data to be reported and ultimately discovered by a wide variety of users, including researchers, students, and other interested individuals. In this way, events such as volcanic eruptions, sea level and climate changes, and a myriad of other recent geological phenomenon can be better understood and integrated with related data.
