SGER: Reconstructing the Glacial Ice Volume Effect Through Paired Planktonic &180 and Uk'37

小赫伯特9811976 这SGER将支持一个试点项目，开发使用组合烯酮不饱和比（UK 1 - 37）和6 - 18 O在一个表面居住的南极有孔虫，以解决海洋表面温度从冰量的海水（这与陆地上的冰量成反比），并被广泛用作过去的海洋环流和全球气候变化的示踪剂。为了给这两个控制分配定量值，需要第二个变量。烯酮的不饱和度被认为是纯粹由环境温度控制，没有冰量的影响，所以结合英国37和618 O应该允许PI解决两个联立方程，以获得定量估计的海洋温度和全球冰量为过去的气候状态。 这些气候模型可以用来了解长期的气候变化。

9811976 Herbert This SGER will support a pilot project to develop the use of combined alkenone unsaturation ratios (Uk1 37) and 6 18 O in a surface-dwelling planktic foraminifer to resolve sea-surface temperature from ice-volume of ocean water (which varies inversely with ice volume on land) and is widely used as a tracer of past changes in ocean circulation and global climate. In order to assign quantitive values to the two controls, a second variable is needed . Alkenone unsaturation is believed to be controlled purely by ambient temperature, with no ice-volume effect, so that combining Uk 37 and 618 O should permit the PI to solve two simultaneous equations to derive quantitative estimates of both ocean temperature and global ice volume for past climate states. These climate models to understand long-term climate variability.
