David McGee’s research focuses on understanding the atmosphere’s response to past climate changes. By documenting past changes in precipitation and winds using geochemical measurements of stalagmites, lake deposits and marine sediments and interpreting these records in the light of models and theory, he aims to offer data-based insights into the patterns, pace and magnitude of past hydroclimate changes. His primary tool is measurements of uranium-series isotopes, which provide precise uranium-thorium dates for stalagmites and lake deposits and allow reconstructions of windblown dust emission and transport using marine sediments.
