1. On the consistent scaling of terms in the sea-ice dynamics equation

   The standard way in which the sea-ice dynamics equation is used in models assumes that the wind stress and ocean drag do not depend on the sea-ice concentration. It is […]

2. Cryptoteuthis brevibracchiata: a new species and genus of cirrate octopod (Octopoda: Cirrata)

   A new species and genus of cirrate octopod, Cryptoteuthis brevibracchiata, is described from a single specimen captured at 2274-2300 m in the Porcupine Seabight, northeastern Atlantic. The species possesses characteristics […]

3. Widespread colonization by polar hypoliths

   High-latitude polar deserts are among the most extreme environments on Earth. Here we describe a large and previously unappreciated habitat for photosynthetic life under opaque rocks in the Arctic and […]

4. Zones of photosynthetic potential on Mars and the early Earth

   Ultraviolet radiation is more damaging on the surface of Mars than on Earth because of the lack of an ozone shield. We investigated micro-habitats in which UV radiation could be […]

5. A Planetary Park system for Mars

   The increasing robotic exploration of Mars and eventual human exploration and settlement of that planet threatens to have a significant environmental impact on scientifically important sites and sites of natural […]

6. Coupling of climate change and biotic UV exposure through changing snow-ice covers in terrestrial habitats

   During the spring, when ozone depletion at the polar regions is at its maximum and consequently the environmental UV exposure is potentially high, many terrestrial communities are covered in snow […]

7. The uses of Martian ice

   In this paper I explore potential relationships between humans and Martian polar ices. Martian ices contain within them multimillion year histories of atmospheric, geological and maybe even biological processes. Polar […]

8. The rights of microbes

   Over the last forty years, the circle of organisms thought worthy of inclusion within an ethical framework has expanded markedly, in large part in response to Aldo Leopold’s ‘land ethic’. […]

9. Impact-shocked rocks – insights into archean and extraterrestrial microbial habitats (and sites for prebiotic chemistry?)

   Impact-shocked gneiss shocked to greater than 10 GPa in the Haughton impact structure in the Canadian High Arctic has an approximately 25-times greater pore surface area than unshocked rocks. These […]

10. Growth in the limpet Nacella concinna from contrasting sites in Antarctica

    Annual shell growth was determined by mark and recapture in the limpet Nacella concinna (Strebel 1908) at two contrasting sites in Antarctica. At Signy Island, 60degreesS, growth was moderately fast, […]
