Short summary
Palaeoclimatological reconstructions aid our understanding of current and future climate change. In the Pliensbachian (Early Jurassic) a climatic cooling event occurred globally. We show that this cooling event has a significant impact on the depositional environment of the Cardigan Bay basin but that the 405 kyr eccentricity cycle remained the dominant control on terrestrial and marine depositional processes.
