The proponents will make Thellier paleointensity determinations on multiple samples of glassy mid-ocean ridge basalt material from about ten dredges and about 40 wax cores from the East Pacific Rise at 15 to 16 degrees North. Well-defined paleointensit values can be reliably obtained from glassy basalt samples and used to differentiate ages at least in the 0 to 2,000 year interval. Selected samples will also be dated by radioisotopic methods.

支持者将对来自北纬15至16度东太平洋海隆的大约10个挖泥船和大约40个蜡芯的玻璃质洋中脊玄武岩材料的多个样本进行Thellier古强度测定。 明确的古强度值可以从玻璃质玄武岩样品中可靠地获得，并用于区分至少在0到2,000年的时间间隔内的年龄。 选定的样本还将通过放射性同位素方法进行日期测定。
