1. Searching for the oldest ice

   It is generally accepted that variations in the precession and eccentricity of Earth’s orbit, and Earth’s axial tilt, influence long-term climate fluctuations; the combined variations are referred to as Milankovitch […]

2. Differential gene expression during the moult cycle of Antarctic krill (Euphausia superba)

   Background: All crustaceans periodically moult to renew their exoskeleton. In krill this involves partial digestion and resorption of the old exoskeleton and synthesis of new cuticle. Molecular events that underlie […]

3. Wave-particle interactions in the equatorial source region of whistler-mode emissions

   Wave-particle interactions can play a key role in the process of transfer of energy between different electron populations in the outer Van Allen radiation belt. We present a case study […]

4. Contrasting the efficiency of radiation belt losses caused by ducted and nonducted whistler-mode waves from ground-based transmitters

   It has long been recognized that whistler-mode waves can be trapped in plasmaspheric whistler ducts which guide the waves. For nonguided cases these waves are said to be “nonducted”, which […]

5. Central place foraging by breeding Cook’s petrel Pterodroma cookii: foraging duration reflects range, diet and chick meal mass

   Pelagic seabirds are central place foragers during breeding and variation in foraging trip duration and range reflect differences in diet and chick provisioning, through the exploitation of divergent habitats of […]

6. Seasonal interactions in the black-legged kittiwake, Rissa tridactyla: links between breeding performance and winter distribution

   Relationships between events in one period of the annual cycle and behaviour in subsequent seasons are key determinants of individual life histories and population dynamics. However, studying such associations is […]

8. Understanding ice-sheet mass balance: progress in satellite altimetry and gravimetry

   Satellite remote sensing has come to dominate the measurement of glacier and ice-sheet change. Three independent methods now exist for assessing ice-sheet mass balance and we focus on progress in […]

9. Frost flowers in the laboratory: Growth, characteristics, aerosol, and the underlying sea ice

   In the laboratory, we have investigated the growth and composition of frost flowers. Their ionic composition has shown little difference from those of field measurements. Young frost flowers grown on […]

10. Ocean tides in the Weddell Sea: New observations on the Filchner-Ronne and Larsen C ice shelves and model validation

    Ocean tides under the large Weddell Sea ice shelves are among the least well observed on Earth. Here we present new, spatially extensive observations of the vertical tidal motion of […]

11. Thermal niche separation in two sympatric tropical intertidal Laternula (Bivalvia: Anomalodesmata)

    Factors determining thermal niche separation of two sympatric infaunal bivalves (Laternula truncata and L. boschasina) occurring in a Singapore mangrove were examined by comparing experienced microhabitat temperature with the thermal […]

12. Mesosphere-to-stratosphere descent of odd nitrogen in February-March 2009 after sudden stratospheric warming

    We use the 3-D FinROSE chemistry transport model (CTM) and Atmospheric Chemistry Experiment Fourier Transform Spectrometer (ACE-FTS) observations to study connections between atmospheric dynamics and middle atmospheric NOx (NOx = […]
