Seasonal Arctic summer ice extent still hard to forecast.

A new study lead by Prof Julienne Stroeve says year-to-year forecasts of the Arctic’s summer ice extent are not yet reliable.

GEOLM021 Melting and Volcanism


To provide an understanding of the origins and emplacement mechanisms of intrusive and extrusive continental magmas, and to recognize textures and mineral assemblages characteristic of specific processes.


Knowledge of: Melting and volcanism on Earth and terrestrial planets.


Local and regional geochemical patterns and anomalies will be compared with global data to understand the evidence for crustal lithospheric and asthenospheric sources of magma, including plumes, subduction, impact volcanism and fundamental Earth heterogeneities. Advanced techniques in quantitative mineralogy and the interpretation of geochemical, mineralogical and petrological data will be introduced, including radiogenic isotopes, trace-element behaviour and melting, mixing, metasomatic and crystallisation models. Rifting, hotspots, large intrusions, caldera formation and high-volume flood lavas will be contrasted with rare low-volume magmas. Familiarization with the corresponding variations in terrestrial volcanic eruption styles throughout the course will be complemented by practical introduction to volcanic hazard assessment and comparative planetary geology.
