High-Frequency Sea Level Changes and Paleoceanography of the Cenomanian-Turonian Greenhorn Sea

PI将进行跨学科调查， 运用沉积学，地层学，古生物学， 古生态学和地球化学，都是为了确定 海平面高频变化的原因和影响 北部塞诺曼-图伦西部内陆航道 美国参考 目的是：1）证实假设， 细粒近海相记录中的准层序 （2）至少在区域范围内的进程，以确定 可容纳空间和沉积速率的空间变化 流入影响层序和准层序的发育 在高频率相对海平面变化期间，3） 评估如何以及通过何种机制， 离岸地点的水平各不相同， 频率海平面变化，和4），以确定如何水 柱特征在这样的过程中变化 变化

PIs will conduct an interdisciplinary investigation, employing sedimentology, stratigraphy, paleontology, paleoecology, and geochemistry, all designed to determine the causes and effects of high-frequency sea-level changes in the Cenomanian-Turonian Western Interior Seaway of North America. Objectives are: 1) to confirm hypothesis that parasequences in the fine-grained, offshore facies record processes of at least regional extent, 2) to determine how spatial changes in accommodation space and rate of sediment influx influenced development of sequences and parasequences during high-frequency relative sea-level changes, 3) to evaluate how, and by what mechanisms, benthic oxygenation levels at offshore sites varied in concert with high- frequency sea-level changes, and 4) to determine how water column characteristics varied over the course of such changes.
