9304831 Fisher PI will calibrate estimated density of later middle through early late Cenomanian waters at a mid-Cretaceous ocean front in the Western Interior Seaway to paleotemperature estimates from stable oxygen isotope analyses measured on planktic foraminifera. Test porosity of planktic foraminifera, and possibly of calcareous nannoplankton, will be used to estimate water density. Specimens will be compared from Montana, Wyoming, and different paleolatitudes from DSDP/ODP sites. This is a research planning grant; planned future research would extend the methods toward the proposed hypersaline "Supertethys" sea of this time period. ***

9304831 Fisher PI将校准估计的密度晚中期到早期晚Cenomanian沃茨在白垩纪中期海洋前在西部内陆海道的古温度估计从稳定的氧同位素分析测量南极有孔虫。 测试孔隙度的浮游有孔虫，可能的钙质nannoplankton，将被用来估计水密度。 将对来自蒙大拿州、怀俄明州和来自DSDP/ODP地点的不同古纬度的标本进行比较。 这是一项研究规划拨款;计划中的未来研究将把这些方法扩展到该时期拟议的高盐“Supertethys”海。 ***
