Abstract Ocean productivity is sensitive to climate change, and its decline in recent decades has profoundly impacted the biosphere. Yet its long-term trajectory under global warming remains a topic lacking consensus. To address this question, we use paired ichthyolith and marine barite accumulation rates to investigate marine productivity and associated biological responses during the Paleocene-Eocene Thermal Maximum.

Research & Teaching The Effectiveness of Cooperative Learning in Teaching Quantitative Reasoning With Ternary Diagrams in a Science Class Quantitative reasoning, although included in most science courses, can be challenging to teach. In this article, we explore whether cooperative learning may help instructors teach quantitative reasoning and enhance students’ understanding and learning experience. Our lesson was taught in a large introductory geoscience course.
