Project outline

Proxies are an essential tool to enhance our understanding of climate change and ocean circulation. Dinoflagellate cysts make excellent proxies because their cysts preserve well and temperature, salinity, ice cover, and nutrient content limit their abundance and diversity. They will be used as a proxy to infer the ocean circulation at a global level during the Neogene and have the potential to help predict future changes. The evolution of Neogene climate is important to study, as modern climate conditions are a direct result of the changes that took place during the last 20 million years. This allows for a better understanding of how and why the natural systems change and what the potential effects of future changes might be. I intend to research how the circulation of the Neogene oceans evolved and use this information to predict future alterations to circulation patterns and determine possible impacts on the global climate. The research involves collecting and collating all the previously published data on dinoflagellate cysts during the Neogene into a database which I will then analyse and enhance by collecting further data to help fill in geographical gaps in the existing data set. Multiple palaeontological climate proxies are important for building reliable climate models, as they are essential to producing the most dependable boundary conditions. With a view to understanding the large scale changes, I will look in finer detail at the Piacenzian, 3.6Ma to 2.588Ma. This period contains a relatively stable warm period, known as the Mid-Pliocene Global warmth (MPGW), compared to the generally cooling climate and was the last sustained warm period found in the geological rcord. I will specifically be researching the North Atlantic Ocean, looking at sites across the ocean to try and understand the development of the North Atlantic Current during the Neogene.
