1. Long-term inter- and intraspecific dietary variation in sibling seabird species

   Northern Macronectes halli and southern giant petrels M. giganteus are opportunistic predators and the dominant avian scavengers in sub-Antarctic and Antarctic ecosystems. At South Georgia, there are globally important breeding […]

2. Breaking all the rules: The first recorded hard substrate sessile benthic community far beneath an Antarctic ice shelf

   The seafloor beneath floating ice shelves accounts roughly a third of the Antarctic’s 5 million km2 of continental shelf. Prior to this study, our knowledge of these habitats and the […]

3. Optimization of radial diffusion coefficients for the proton radiation belt during the CRRES era

   Proton flux measurements from the Proton Telescope instrument aboard the CRRES satellite are revisited, and used to drive a radial diffusion model of the inner proton belt at 1.1 ≤ […]

4. Using a sclerochronological approach to determine a climate-growth relationship for waved whelk, Buccinum undatum, in the U.S. Mid-Atlantic

   Using growth rings observed in statoliths, the size-at-age relationship was modeled for waved whelk (Buccinum undatum) populations within the Mid-Atlantic Bight. A total of 45 sites in the Mid-Atlantic were […]

5. From warm to cold waters: new insights into the habitat and trophic ecology of Southern Ocean squids throughout their life cycle.

   Cephalopods play a major role in marine ecosystems, yet very little is known about the dynamics of their habitat use and trophic ecology across the stages of their life cycle, […]

6. A multi-sensor and modeling approach for mapping light under sea ice during the ice-growth season

   Arctic sea ice is shifting from a year-round to a seasonal sea ice cover. This substantial transformation, via a reduction in Arctic sea ice extent and a thinning of its […]

7. Isotopic signatures of major methane sources in the coal seam gas fields and adjacent agricultural districts, Queensland, Australia

   In regions where there are multiple sources of methane (CH4) in close proximity, it can be difficult to apportion the CH4 measured in the atmosphere to the appropriate sources. In […]

8. Mercury biomagnification in a Southern Ocean food web

   Biomagnification of mercury (Hg) in the Scotia Sea food web of the Southern Ocean was examined using the stable isotope ratios of nitrogen (δ15N) and carbon (δ13C) as proxies for […]

9. A revised interpretation of the Chon Aike magmatic province: Active margin origin and implications for the opening of the Weddell Sea

   Late Triassic – Jurassic igneous rocks of the Antarctic Peninsula and Patagonia provide evidence for the evolution of the margin of southwestern Gondwana. We present new geochronological (LAICP-MS zircon U-Pb […]

10. In-situ image analysis of habitat heterogeneity and benthic biodiversity in the Prince Gustav Channel, Eastern Antarctic Peninsula.

    Habitat heterogeneity is important for maintaining high levels of benthic biodiversity. The Prince Gustav Channel, on the Eastern Antarctic Peninsula, is characterized by an array of habitat types, ranging from […]

11. Development of space weather reasonable worst case scenarios for the UK National Risk Assessment

    Severe space weather was identified as a risk to the UK in 2010 as part of a wider review of natural hazards triggered by the societal disruption caused by the […]

12. Evidence for strong environmental control on bacterial microbiomes of Antarctic springtails

    Collembola are a key component of the soil biota globally, playing an important role in community and ecosystem dynamics. Equally significant are their associated microbiomes, that can contribute to key […]
