2. Using fatty acid analysis to elucidate the feeding habits of Southern Ocean mesopelagic fish

   Fatty acid biomarkers were used to investigate the feeding ecology of 17 mesopelagic fish species occurring in the Southern Ocean. Fatty acid signatures of species where little or no dietary […]

3. Trophic position of deep-sea fish – assessment through fatty acid and stable isotope analyses

   To investigate the trophic ecology of two of the dominant families of deep-sea fish (Macrouridae and Moridae) fatty acid and stable isotope analyses were applied to liver and muscle samples […]

4. Subglacial intermediate volcanism at Kerlingarfjoll, Iceland: magma-water interactions beneath thick ice

   The products of andesite and dacite glaciovolcanism at Kerlingarfjoll are unlike others previously described in the literature. Three sequences of lithofacies are described and interpreted here. The andesitic deposits at […]

5. Quantifying the metabolic cost to an Antarctic liverwort of responding to an abrupt increase in UVB radiation exposure

   We quantified the metabolic cost to the Antarctic leafy liverwort Cephaloziella varians of responding to an abrupt increase in ultraviolet B (UVB) radiation exposure in the natural environment at Rothera […]

6. Sediment infill of subglacial meltwater channels on the West Antarctic continental shelf

   Subglacial meltwater plays a significant yet poorly understood role in the dynamics of the Antarctic ice sheets. Here we present new swath bathymetry from the western Amundsen Sea Embayment, West […]

7. Bedform topography and basal conditions beneath a fast-flowing West Antarctic ice stream

   A grid of seismic reflection lines has been used to image basal topography and infer basal conditions and flow processes beneath similar to 140 km(2) of Rutford Ice Stream, West […]

8. Nature of the Antarctic Peninsula Ice Sheet during the Pliocene: geological evidence and modelling results compared

   In this paper, we examine the nature of the Pliocene Antarctic Peninsula Ice Sheet by comparing the terrestrial and marine geological records of the Antarctic Peninsula and surrounding sea floor […]

9. Interpreting temperature information from ice cores along the Antarctic Peninsula: ERA40 analysis

   Analysis of ERA40 temperature and accumulation data suggests that annual mean isotopic fluctuations due to temperature change will be geographically very variable across the Peninsula: isotopic variations of 0.4 parts […]

10. Understanding the regional variability of eddy diffusivity in the Pacific sector of the Southern Ocean

    A diagnostic framework is presented, based on the Nakamura effective diffusivity, to investigate the regional variation in eddy diffusivity. Comparison of three different diffusivity calculations enables the effects of locally […]

11. Robustness of an effective diffusivity diagnostic in oceanic flows

    The robustness of Nakamura’s effective diffusivity diagnostic for quantifying eddy diffusivities of tracers within a streamwise-average framework is carefully examined in an oceanographic context, and the limits of its applicability […]

12. Local mixing events in the upper troposphere and lower stratosphere. Part II: seasonal and interannual variability

    The Lyapunov diffusivity is used to investigate local isentropic mixing events in the upper troposphere lower stratosphere (UTLS) region. The diagnostic highlights the seasonal cycle of the longitudinally varying mixing […]
