2. Revised assessment for Oceania humpbacks: survey design considerations and power analysis

   The Oceania population of humpback whales, comprising sub-stocks E2, E3, and F, was heavily depleted by whaling operations in the 20th century and is now classed as Endangered by the […]

3. Population modelling of humpback whales in East Australia (BSE1) and Oceania (BSE2, BSE3, BSF2)

   Humpback sub-stocks BSE1 (East Australia), BSE2 (New Caledonia), BSE3 (Tonga) and BSF2 (French Polynesia) show significant genetic differentiation, yet share common high latitude feeding grounds between 130E-100W and were subject […]

4. Decline in local abundance of bottlenose dolphins (Tursiops truncatus) in the Bay of Islands, New Zealand

   Regional populations of bottlenose dolphins (Tursiops truncatus) around New Zealand are genetically isolated from each other and the species was recently classified as nationally endangered based on relatively small population […]

5. Mesospheric CO above Troll station, Antarctica observed by a ground based microwave radiometer

   This paper presents mesospheric carbon monoxide (CO) data acquired by the ground-based microwave radiometer of the British Antarctic Survey (BAS radiometer) stationed at Troll station in Antarctica (72° S, 2.5° […]

6. The plasmasphere during a space weather event: first results from the PLASMON project

   The results of the first 18 months of the PLASMON project are presented. We have extended our three, existing ground-based measuring networks, AWDANet (VLF/whistlers), EMMA/SANSA (ULF/FLRs), and AARDDVARK (VLF/perturbations on […]

7. Aliens in Antarctica: Assessing transfer of plant propagules by human visitors to reduce invasion risk

   Despite considerable research on biological invasions, key areas remain poorly explored, especially ways to reduce unintentional propagule transfer. The Antarctic represents a microcosm of the situation, with the numbers of […]

8. Mechanisms for the Holton-Tan relationship and its decadal variation

   This study provides a mechanistic explanation of why the Holton-Tan (HT) effect, a phenomenon in which the strength of northern stratospheric winter polar vortex synchronizes with the equatorial quasi-biennial oscillation […]

10. The atmospheric HCHO budget at Dumont d’Urville (East Antarctica): Contribution of photochemical gas-phase production versus snow emissions

    HCHO was monitored throughout the year 2009 at the coastal East Antarctic site of Dumont d’Urville (DDU) using Aerolaser AL-4021 analyzers. The accurate determination of less than 100 pptv required […]

11. Experimental influence of pH on the early life-stages of sea urchins II: increasing parental exposure times gives rise to different responses

    Many studies into the responses of early life-stages to ocean acidification utilise offspring obtained from parents reared under present-day conditions. Their offspring are directly introduced to altered-pH conditions. This study […]

12. Characterisation of vertical BrO distribution during events of enhanced tropospheric BrO in Antarctica, from combined remote and in-situ measurements

    Tropospheric BrO was measured by a ground-based remote-sensing spectrometer at Halley in Antarctica in spring 2007, and BrO was measured by satellite-borne remote-sensing spectrometers using similar spectral regions and similar […]
