ROW: Seasonal and Interannual Variations in the Distribution, Abundance, and Isotopic Composition of Planktonic Foraminifera within an Upwelling Region

提供的资金用于支持调查员正在进行的研究浮游有孔虫对海洋上升流的反应的努力。这一研究区域受到加州海流强度的季节性和年际变化的强烈影响，导致了明显的埃克曼诱导的上升流周期。这项研究将导致：(1)加深对浮游有孔虫生态的了解，这些浮游有孔虫生活在高度不稳定但富有生产力的季节性上升流栖息地；(2)记录这些物种的季节演替和组合组成：(3)确定对上升流和/或浮游植物水华条件做出反应的物种；(4)识别记录在有孔虫测试稳定同位素组成中的上升流信号；(5)生物扰动和非生物扰动沉积物中有孔虫的季节丰度/分布模式和沉积组合的同位素组成。

Funds are provided to support the investigator's ongoing efforts to study the response of planktonic foraminifera to oceanic upwelling. This study area is strongly influenced by seasonal and interannual variations in the strength of the California Current, resulting in pronounced periods of Ekman- induced upwelling. The study will result in an (1) increased understanding of the ecology of planktonic foraminifera which live in a highly unstable but productive seasonal upwelling habitat; (2) documentation of the seasonal succession and assemblage composition of these species: (3) identification of species that respond to periods of upwelling and/or phytoplankton bloom conditions; (4) identification of upwelling signals recorded in the stable isotopic composition of foraminiferal tests; (5) an composition of foraminiferal seasonal abundance/distribution patterns and isotopic composition to sedimentary assemblages in both bioturbated and non-bioturbated sediments.
