Does Sedimentary Organic S13C Record Variations in Ocean ?CO2(aq)! During Quaternary Glaciation?

根据在现代海洋的观测，我们假设从vostok冰芯资料中可以看出，较低的冰川海洋CO2 （aq）将在冰川>中表现为明显较高的沉积物三角洲C13 （org）值。>年龄层。这一假设将通过仔细选择和分析来自存档沉积物岩心的适当层位的材料来验证。所使用的岩心将代表赤道或高b> . b> .南b>。并将经过先前关于地质年代学和古海洋学的研究。将选择岩心材料来记录晚第四纪间冰期和冰期的同位素丰度，并特别注意过渡。

Based on observations in the modern ocean, it ishypothesized that lower glacial ocean CO2 (aq) now evident fromVostok ice core data will be expressed as significantly highersediment delta C13 (org) values in glacial>.>age strata. Thishypothesis will be tested by carefully selecting and analyzingmaterial from appropriate horizons within archived sedimentcores. The cores to be used will be representative of either theequatorial or the high>.>southern>.>latitude Atlantic Ocean, and willhave undergone previous study with respect to geochronology andpaleoceanography. Core material will be selected to documentisotopic abundances within late Quaternary interglacial andglacial periods, with special attention to the transitions.
