Microscopic fossils are abundant in marine sediments. Our research focuses on a group of organisms called planktonic foraminifera that build their shells out of calcium carbonate. When the planktonic foraminifera die they sink to the seafloor and can be examined from deep sea cores collected from the International Ocean Discovery Program (IODP). Planktonic foraminifera provide one of the best fossil records, because of their abundance and diversity. We will use these fossils to determine when different species evolved and went extinct over the last 15 million years. Expedition 363 will recover sediments with high sedimentation rates and well preserved microfossils from the Western Pacific Warm Pool. We will be able to compare the timing of evolutionary and extinction events from the western Pacific to previous record from elsewhere (such as the Atlantic Ocean). This will allow us to test whether the timing of extinction events is synchronous or diachronous between different ocean basins.

显微化石在海洋沉积物中非常丰富。我们的研究集中在一组被称为浮游有孔虫的生物体上，它们用碳酸钙建造外壳。当浮游有孔虫死亡时，它们会沉入海底，可以从国际海洋发现计划（IODP）收集的深海岩心中进行检查。浮游有孔虫提供了最好的化石记录之一，因为它们的丰富性和多样性。我们将利用这些化石来确定不同物种在过去1500万年中何时进化和灭绝。363号考察队将从西太平洋暖池中恢复具有高沉积速率和保存完好的微体化石的沉积物。我们将能够将西太平洋的进化和灭绝事件的时间与其他地方（如大西洋）的先前记录进行比较。这将使我们能够测试灭绝事件的时间在不同的海洋盆地之间是同步的还是历时的。
