Collaborative Research: Testing the Impact of Seasonality on Benthic Foraminifers as Paleoenvironmental Proxies.

本项目研究南极半岛西部gerlach - Bransfield海峡地区北部有孔虫数量和壳组成的季节变化。其目标是提高对微动物和地球化学指标的解释，以重建古代洋流、气候和生态。由于季节变化可能极大地影响解译，本项目侧重于南极地区，在那里强烈的季节变化应比在不那么极端的中纬度地区产生更明显的信号。研究结果将有助于更好地理解季节性生产力的耦合关系，并改善区域重建。更广泛的影响是研究生、本科生和博士后的教育；以及向讲英语和西班牙语的公众提供服务。这项工作还将提高社会对过去气候变化的理解，将其作为未来气候变化的类比。

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.
