2. The measurement of daily energy expenditure—an evaluation of some techniques

   An energy balance survey was conducted on an Antarctic base on 12 individuals for periods varying between 6 and 12 months. Energy expenditure was estimated using two activity/dairy card techniques […]

3. The measurement of food and energy intake in man—an evaluation of some techniques

   A dietary survey was carried out on an Antarctic base over a period of 6 to 12 months on twelve individuals. Three methods of determining individual food and energy intake […]

4. A longitudinal study of body weight and body fat changes in Antarctica

   Body weight and body fat changes (calculated from skinfold thickness) that occurred in a male population spending a year on an Antarctic base are described. There was a marked individual […]

5. Genistein and estradiol have common and specific impacts on the sea bass (Dicentrarchus labrax) skin-scale barrier

   Teleost fish scales play important roles in animal protection and homeostasis. They can be targeted by endogenous estrogens and by environmental estrogenic endocrine disruptors. The phytoestrogen genistein is ubiquitous in […]

6. Organic compounds in a sub-Antarctic ice core: A potential suite of sea-ice markers

   Investigation of organic compounds in ice cores can potentially unlock a wealth of new information in these climate archives. We present results from the first ever ice core drilled on […]

7. Humans and wind, shaping Antarctic soil arthropod biodiversity

   1. Biodiversity loss has increased globally in recent years. The major threat to Antarctica’s unique terrestrial biodiversity is the establishment of non-native species. Nonetheless, while preventing the introduction of non-native […]

8. Physical length scales of wind-blown snow redistribution and accumulation on relatively smooth Arctic first-year sea ice

   Snow thickness measurements over relatively smooth Arctic first-year sea ice, obtained near Cambridge Bay, Nunavut, Canada (2014, 2016 and 2017) and near Elson Lagoon, Alaska, USA (2003 and 2006), are […]

9. Influence of sea‐ice‐derived halogens on atmospheric HOx as observed in springtime coastal Antarctica

   We present first observations of OH and (HO2 + RO2) carried out in Antarctica outside the summer season. Measurements were made over 23 days in spring at the coastal Antarctic […]

10. Myctophid fish (Family Myctophidae) are central consumers in the food web of the Scotia Sea (Southern Ocean)

    Myctophid fish are the most abundant and diverse mesopelagic fishes in the Southern Ocean. They are a conduit of energy between primary consumers and higher marine predators, and between the […]

11. Semiautomated detection and mapping of vegetation distribution in the Antarctic environment using spatial-spectral characteristics of WorldView-2 imagery.

    Effective monitoring of changes in the geographic distribution of cryospheric vegetation requires high-resolution and accurate baseline maps. The rationale of the present study is to compare multiple feature extraction approaches […]

12. Global patterns of species richness in coastal cephalopods

    Within the context of global climate change and overfishing of fish stocks, there is some evidence that cephalopod populations are benefiting from this changing setting. These invertebrates show enhanced phenotypic […]
