While observed frequency bandwidths of auroral Z mode radiation cannot be directly accounted for in terms of direct cyclotron maser instability generation, ray tracing in a hot plasma indicates that […]
The HOTRAY ray tracing code is used to study the refraction of electrostatic waves into Z mode radiation, and to calculate the path integrated growth rate. A plasma density model […]

The globally-observed relationship between oceanic barium and the macronutrient silicic acid results from the shared influence of large-scale ocean circulation and mixing on the two elements, and the inherent link […]
Dietary studies of marine predators offer an immediate signal of foodweb changes occurring at lower trophic levels, and therefore are often used to assess the ecosystem status of marine systems. […]
Mollusc shells are unique adaptations that serve to protect the organisms that make them, and are a defining feature of the phylum. However the molecular underpinnings of shell forming processes […]
This thesis presents the first high-resolution palaeoceanographic study of environmental changes in the Amundsen Sea sector of the West Antarctic continental margin during the Late Quaternary. This part of the […]
