This project studies seasonal variation in the abundance and shell composition of foraminifera from the northern Gerlache-southern Bransfield Straits region of the Western Antarctic Peninsula. Its goal is to improve interpretation of microfaunal and geochemical proxies for reconstruction of ancient ocean currents, climate, and ecologies. Since seasonal variation may greatly affect interpretation, this project focuses on the Antarctic region, where intense seasonality should generate a more obvious signal than at the less extreme mid-latitudes. The results should allow a better understanding of the coupling to seasonal productivity, as well as improve regional reconstructions.The broader impacts are graduate, undergraduate, and postdoctoral student education; as well as outreach to both the English and Spanish-speaking public. The work will also improve society's understanding of past climate change as an analogue to the future.

本项目研究南极西部半岛北方杰拉希-布兰斯菲尔德海峡南部地区有孔虫丰度和外壳组成的季节变化。其目标是改善对微型动物群和地球化学替代物的解释，以重建古代洋流、气候和生态。由于季节性变化可能极大地影响解释，本项目侧重于南极地区，那里强烈的季节性应比不太极端的中纬度地区产生更明显的信号。研究结果应能更好地了解季节性生产力的耦合，以及改善区域重建。更广泛的影响是研究生，本科生和博士后学生教育;以及推广到英语和西班牙语的公众。这项工作还将提高社会对过去气候变化的理解，将其作为未来的类比。
