Field observations made during the 2004-2005 field season, using such features as sill steps, sill bridges, orientated phenocrysts and asymmetric structures to determine regional magma flow directions in the Theron Mountains. A full photographic record of the cliffs was made at a transit of 1km out from the cliffs.

Geological analyses were conducted on rock samples collected in Dronning-Maud Land during the 2007-2008 field season. Analyses included grain-size determination, dating, whole rock and inclusion mineralogy, and geochemical analyses. All of the samples taken were of rocks that were found cropping out as nunataks. The investigation took place entirely within the the Dronning-Maud Land area of East Antarctica (Norwegian Sector).

Geochemical analysis of rock samples acquired by dredging activities in the Scotia Sea between Feb and Mar 2004 aboard James Clark Ross (cruise no JR77). The initial aim of this project was to carry out a higher resolution geochemical study of mantle flow using existing samples. This confirmed flow from the Bouvet domain into the East Scotia Sea and placed constraints on flow pathways. The second stage was to sample further within the West Scotia Sea and to use elemental and isotope (Sr, Nd, Pb, Hf) analyses to fingerprint mantle provenance. The results were used to locate and investigate the nature of the Pacific-South Atlantic mantle domain boundary and thus to contribute to the understanding and quantification of global upper mantle fluxes.

Despite the important tectonic and stratigraphic setting, rocks from the English Coast area remain largely unstudied, as the paucity of exposure has hindered detailed structural and sedimentological analysis. Samples were collected for zircon analysis following a traverse starting at the English Coast and ending at Sky-Blu. A total of around 250kg of rock were collected and rocks at Fitzgerald Bluffs were revisited and sampled for the first time in 25 years. Highlights included the recognition of a previously undiscovered granitoid body and the discovery of fossils that tentatively indicate that Permian rocks are more widespread in the region.

Cosmogenic isotope exposure-age dating (Aluminium-26, Beryllium-10 and Chlorine-36) of granite erratic boulders and locally derived glacially transported basalt boulders from ice-free land on James Ross Island, northeastern Antarctic Peninsula. These data are used to define the evolution of Last Glacial Maximum (LGM) ice in the adjacent Prince Gustav region and the timing and duration of deglacial ice-streaming events.

Sample inventory data related to a field campaign of approximately 10 weeks, carried out during 2007-2008. The primary focus was sample collection, with the rest of the time being used for mapping. All of the samples taken were of rocks that were found cropping out as nunataks. The investigation took place entirely within the the Dronning-Maud Land area of East Antarctica (Norwegian Sector).

The collection consists of over 1 tonne of rock samples from the Theron Mountains, with an emphasis on the mainline of the enscarpment, which was reached by climbing the scree slopes at the base of the cliffs or by traversing the skyline, during the 2004/2005 field season.

Laboratory AMS (Anisotropy of Magnetic Susceptibility) measurements made on a collection of sill samples collected from the Theron Mountains, Antarctica, during the 2004-2005 field season. AMS involves the collection of some 1 metric tonne of oriented samples and the lab-based determination of the magmatic flow fabric of the rock. Models concerning the location of mantle plumes and triple junctions associated with the Mesozoic break-up of Gondwana in the Antarctic-southern Africa sector are not capable of independent testing, other than by geochemical and age dating methods. We determined the regional flow directions of the magmas in dyke and sill complexes in the areas of postulated plume heads and related triple points on the opposing conjugate margins. AMS was utilised to determine magmatic flow directions and constrain these with macroscopic observations of flow indicators.

Ice sheet model runs based on the Glimmer thermo-mechanical ice sheet model. Glacial modelling was used to simulate former WAIS (West Antarctic Ice Sheet) dynamics (specifically grounding line and ice volume changes) in the Weddell Sea embayment, constrained by newly acquired field data (see related datasets).

Dredging for rock samples was conducted in the West Scotia Sea during James Clark Ross cruise no JR77 between Feb and Mar 2004. The aim was to acquire rock samples to constrain the history of the mantle beneath the Scotia Sea, from which the oceanic crust was derived by melting. Twenty days of rock dredging were conducted at fourteen sites in five main areas. Thirteen dredges were successful in recovering oceanic rocks of mixed sizes, up to and including very large boulders and dredge paths of up to 1 km were followed. The cruise also (remarkably) recovered fresh mantle peridotite nodules from the West Scotia Ridge, the first of its type - to our knowledge - from the world''s ocean ridge system.
