Full Description
This exam evaluates knowledge concerning geochemical proxies and their role in indicating past climatic changes. Candidates will articulate the principles behind the selection and analysis of various proxies.
Geochemical proxies are foundational in understanding paleoceanographic conditions, directly informing climate research and policy through empirical evidence from the geological record.
Candidates will be tested on their abilities to explain the significance of different geochemical markers, their respective applications, and the analytical methods used in their study.
Preparation should include familiarity with established proxies and their interpretations, alongside case studies demonstrating their relevance in climate science.
Sample Questions
- What is the significance of oxygen isotopes as a geochemical proxy in paleoclimate studies?
- How do geochemical proxies enhance our understanding of historical climate variability?
