D'Hondt 9302483 The PIs will use chronostratigraphic techniques to test the regional and global extent of Late Cretaceous oceanographic conditions. The oceanographic response to Milankovitch forcing during periods of stability will be deciphered through an integrated analysis of paleoceanographic proxies and development of cyclostratigraphic records at critical sites. Magnetic susceptibility, carbonate and terrigenous flux, planktonic foraminiferal and stable isotopic studies are planned. The focus will be on South Atlantic and Indian Ocean sites.

D'Hondt 9302483 PI将使用年度地层学技术来测试白垩纪晚期海洋学条件的区域和全球范围。在稳定期间，对米兰科维奇强迫的海洋响应将通过对古环摄影代理的综合分析和关键地点的环层学记录的发展进行解密。计划磁化易感性，碳酸盐和陆磁通量，浮游有孔虫和稳定的同位素研究。 重点将放在南大西洋和印度洋遗址。
