中文摘要

在加州边境地带和加利福尼亚湾的几个地点，提供了资金来支持从层状沉积物到生物扰动沉积物转变的原因研究。假设是从层压到生物扰动条件的转变是由于氧气利用率的变化。以前的研究更多地关注进入盆地的深水中氧气浓度的变化和深盆地通风率的变化，这是最可能的解释。计划在加利福尼亚/巴哈边缘的几个盆地的横断面上进行一次取心巡航，收集多个岩心。这项研究将与墨西哥科学家合作进行。
英文摘要
Funds are provided to support the study of the cause of a shift from laminated to bioturbated sediments inferred for several locations in the California Borderland and Gulf of California. The hypothesis is that the shift from laminated to bioturbated conditions is due to changes in the oxygen utilization rate. Previous studies had focussed more at changes in oxygen concentration in the deep waters entering the basins and changes in the ventilation rate of the deep basins as the most probable explanation. A coring cruise is planned to collect multicores along transects in several basins along California/Baja margin. Study will be in collaboration with Mexican scientists.
