2. Comparison of the oxygen isotope signatures in speleothem records and iHadCM3 model simulations for the last millennium

   Improving the understanding of changes in the mean and variability of climate variables as well as their interrelation is crucial for reliable climate change projections. Comparisons between general circulation models […]

3. Efficient path estimation through parallel media for wide-beam ice-sounding radar.

   The authors propose an algorithm to estimate the path followed by refracted signals from a source to a target, through a medium formed by uniform parallel layers with known different […]

4. Wintertime Southern Hemisphere jet streams shaped by interaction of transient eddies with Antarctic orography

   The wintertime Southern Hemisphere extratropical circulation exhibits considerable zonal asymmetries. We investigate the roles of various surface boundary conditions in shaping the mean state using a semi-realistic, atmosphere-only climate model. […]

5. Paleocene high-latitude leaf flora of Antarctica Part 1: Entire-margined angiosperms

   Paleocene leaf floras are rare in high latitudes of the Southern Hemisphere, where studies have shown higher taxonomic diversity compared to Northern Hemisphere equivalents. The floras provide valuable insights into […]

6. An 83 000-year-old ice core from Roosevelt Island, Ross Sea, Antarctica

   In 2013 an ice core was recovered from Roosevelt Island, an ice dome between two submarine troughs carved by paleo-ice-streams in the Ross Sea, Antarctica. The ice core is part […]

7. Ethics review: Race Impact Survey for the UK Polar Community

   The ambition of the Diversity in UK Polar Science Initiative (DiPSI) – established in September 2019 – is to promote and enhance polar research opportunities in the UK for all currently […]

8. Evolution of the geomagnetic daily variation at Tatuoca, Brazil, from 1957 to 2019: a transition from Sq to EEJ

   The magnetic equator in the Brazilian region has moved over 1,100 km northward since 1957, passing the geomagnetic observatory Tatuoca (TTB), in northern Brazil, around 2013. We recovered and processed […]

9. The impact of the Amundsen Sea freshwater balance on ocean melting of the West Antarctic Ice Sheet

   The Amundsen Sea has the highest thinning rates of ice shelves in Antarctica. This imbalance is caused by changes in ocean melting induced by warm Circumpolar Deep Water (CDW) intrusions. […]

10. Radiosonde observations of a wintertime meridional convergence of gravity waves around 60°S in the lower stratosphere

    Satellite observations show that there is a wintertime hotspot of gravity wave activity, located mainly over the ocean, around 60°S in the stratosphere However, the sources of the gravity waves […]

11. Stable isotopes demonstrate intraspecific variation in habitat use and trophic level of non‐breeding albatrosses

    The non‐breeding period is critical for restoration of body condition and self‐maintenance in albatrosses, yet detailed information on diet and distribution during this stage of the annual cycle is lacking […]

12. WMO evaluation of northern hemispheric coldest temperature: -69.6°C at Klinck Greenland, 22 December 1991

    A World Meteorological Organization (WMO) Extremes Evaluation Committee investigated an observation of −69.6 °C by Klinck Automatic Weather Station (AWS) in Greenland on 22 December 1991 as the lowest temperature […]
