Bacterial Influences on Algal paleo-proxies

Throughout Earth’s history, coccolithophore algae have been living and dying in the oceans and algal remains have been accumulating on the bottom of the ocean. Unique algal relics carry valuable information in their chemistry, environmental information that was “recorded” while the algae were still alive. These remains are referred to as paleo-proxies as they serve as indicators for past environmental conditions. Our group studies the bacterial influence on algal paleo-proxies, and specifically how algal-bacterial interactions influence our interpretation of the geological record.
