1. Past and future dynamics of the Brunt Ice Shelf from seabed bathymetry and ice shelf geometry

   The recent rapid growth of rifts in the Brunt Ice Shelf appears to signal the onset of its largest calving event since records began in 1915. The aim of this […]

4. Impact of ocean acidification and high solar radiation on productivity and species composition of a late summer phytoplankton community of the coastal Western Antarctic Peninsula

   The Western Antarctic Peninsula (WAP), one of the most productive regions of the Southern Ocean, is currently undergoing rapid environmental changes such as ocean acidification (OA) and increased daily irradiances […]

5. Segmented flow coil equilibrator coupled to a proton transfer reaction mass spectrometer for measurements of a broad range of volatile organic compounds in seawater

   We present a technique that utilises a segmented flow coil equilibrator coupled to a proton-transferreaction mass spectrometer to measure a broad range of dissolved volatile organic compounds. Thanks to its […]

6. Education and outreach by the Antarctic Treaty Parties, Observers and Experts under the framework of the Antarctic Treaty Consultative Meetings

   The development of formal discourse about education and outreach within the Antarctic Treaty Consultative Meetings (ATCM), and the influence of major international activities in this field, are described. This study […]

7. Very strong atmospheric methane growth in the four years 2014 – 2017: Implications for the Paris Agreement

   Atmospheric methane grew very rapidly in 2014 (12.7±0.5 ppb/yr), 2015 (10.1±0.7 ppb/yr), 2016 (7.0± 0.7 ppb/yr) and 2017 (7.7±0.7 ppb/yr), at rates not observed since the 1980s. The increase in […]

8. Van Allen Probes observations of chorus wave vector orientations: Implications for the chorus-to-hiss mechanism

   Using observations from the Van Allen Probes EMFISIS instrument, coupled with ray tracing simulations, we determine the fraction of chorus wave power with the conditions required to access the plasmasphere […]

9. On the distinctiveness of oceanic raindrop regimes

   Representation of the drop size distribution (DSD) of rainfall is a key element of characterizing precipitation in models and observations, with a functional form necessary to calculate the precipitation flux […]

10. Impact of abrupt sea ice loss on Greenland water isotopes during the last glacial period

    Greenland ice cores provide excellent evidence of past abrupt climate changes. However, there is no universally accepted theory of how and why these Dansgaard–Oeschger (DO) events occur. Several mechanisms have […]

11. The dominant role of extreme precipitation events in Antarctic snowfall variability

    Antarctic snowfall consists of frequent clear‐sky precipitation and heavier falls from intrusions of maritime airmasses associated with amplified planetary waves. We investigate the importance of different precipitation events using the […]

12. Soil bacterial diversity is positively associated with air temperature in the maritime Antarctic

    Terrestrial ecosystems in the maritime Antarctic experienced rapid warming during the latter half of the 20th century. While warming ceased at the turn of the millennium, significant increases in air […]
