Description: Phytoplankton – single cellular organisms that photosynthesise in the surface ocean – are the base of the open ocean marine food chain. In the mid-to-high latitude oceans phytoplankton growth is often dominated by rapid cell growth over a large area through spring and early summer, so called phytoplankton ‘blooms’. Although these blooms consist of single celled organisms, they reach such abundances as to be observable from space (Figure 1). More information...

Description: Earth history is rich in examples of extreme climatic changes. The Carnian Pluvial Episode (CPE) ~234–232 Ma ago was one such event, which caused minor extinctions but major ecological changes, and initiated the evolution and radiation of modern plant families, including bennettitaleans, modern More information...

Description: Project Summary
Planktonic foraminifera are single-celled marine protists that build a calcium carbonate (calcite) shell, which is readily preservable in deep sea marine sediments. They have existed for ~150 million years, are found in all our global oceans, and have one of the best species-level fossil records known to science. Consequently, they are widely employed for palaeoenvironmental and biostratigraphic research and are increasingly becoming a model system for macroevolutionary analysis. More information...

Description: The list of ‘potentially Earth-like’ rocky exoplanets in the galaxy continues to grow, and recent instrumental advances are paving the way to the analysis of their atmospheric compositions. But which planets should we study in more detail? Are planets larger or smaller than Earth more likely to host complex (e.g. multicellular or eukaryotic) life? Should we be looking around stars larger or smaller than our own Sun? Do planets need to be of a certain age before complex life becomes possible? More information...

Description: Models of future climate change are, for the most part, informed by observational data spanning the last c.150 years – a period that has seen only limited climatic variability. To test our long-term projections of Earth system responses we exploit the geological record. Previous climatically warm periods, e.g. the Last Interglacial (LIG; 130-116 ka), provide natural laboratories to study landscape and ecosystem responses to warmer-than-present conditions.

Description: Background
The diversity of modern marine animals has increased dramatically over the past 230 million years, beginning with an event called the Mesozoic Marine Revolution (MMR). Over this period, marine fauna has gradually developed from sessile, epifaunal benthic assemblages in the Palaeozoic and early Mesozoic to more motile and structured/tiered communities we see today through the Late Triassic, Jurassic and Cretaceous.
Is there evidence of changes in trophic structure and trait evolution that indicate evolutionary escalation in Mesozoic oceans? More information...

Description: In this project you will investigate how the availability of iron and manganese in the oceans controls the global carbon and oxygen cycles, and hence the evolution of Earth’s climate and surface conditions over past, present and future timescales.
Project background:
The availability of macronutrients (like phosphorus and nitrogen) and micronutrients (like iron and manganese) has played a fundamental role in regulating climate and surface conditions over Earth’s history, and will play a critical role in sustaining life on our planet into the future.

Description: The Early Jurassic (201-174 Myrs ago) represents a time of marked environmental changes and evolution of the Earth system: Climate oscillated between cold and warm modes (Korte and Hesselbo, 2011), seawater chemistry changed substantially (Weldeghebriel et al., 2022) and, along with the evolution of calcifiers, drove changes in the location and mineralogy of carbonate deposition (Ridgwell, 2005; Sandberg, 1983). The carbon cycle underwent several perturbations thought to be driven by volcanism and often associated with the reduced availability of oxygen in the oceans. More information...

Description: The rise of oxygen on the early Earth has been recognised as one of the most significant episodes in the history of our planet, and this initial rise set in motion a prolonged chain of events that ultimately resulted in the habitable conditions we now enjoy. In recent years, the topic of early Earth oxygenation has received a huge amount of attention, and almost without exception, traditional views on the timing, causes and consequences of oxygenation have been shown to be incorrect (e.g., Krause et al., 2018; Alcott et al., 2019).
