1. Frost flower surface area and chemistry as a function of salinity and temperature

   Frost flowers play a role in air-ice exchange in polar regions, contribute to tropospheric halogen chemistry, and affect ice core interpretation. Frost flowers were observed and collected on the Hudson […]

2. Morphology of the upper continental slope in the Bellingshausen and Amundsen Seas – implications for sedimentary processes at the shelf edge of West Antarctica

   Swath bathymetric and sub-bottom profiler data reveal a variety of submarine landforms such as gullies, slide scars, subtle shelf edge-parallel ridges and elongated depressions, and small debris flows along the […]

3. Ice-ocean processes over the continental shelf of the southern Weddell Sea, Antarctica: a review

   Interactions between the Southern Ocean and the Weddell Sea ice shelves are important both to the Antarctic Ice Sheet and to the production of globally significant water masses. Here we […]

4. Responses of plants in polar regions to UVB exposure: a meta-analysis

   We report a meta-analysis of data from 34 field studies into the effects of ultraviolet B (UVB) radiation on Arctic and Antarctic bryophytes and angiosperms. The studies measured plant responses […]

6. Climate spectrum estimation in the presence of timescale errors

   We introduce an algorithm (called REDFITmc2) for spectrum estimation in the presence of timescale errors. It is based on the Lomb-Scargle periodogram for unevenly spaced time series, in combination with […]

7. Recurrent substorm activity during the passage of a corotating interaction region

   Recent observations of magnetospheric dynamics driven by interaction with both high-speed solar wind streams (HSSs) and interplanetary coronal mass ejections (ICMEs) have shown periodic substonns to be common under strong […]

8. A superposed epoch analysis of auroral evolution during substorm growth, onset and recovery: open magnetic flux control of substorm intensity

   We perform two superposed epoch analyses of the auroral evolution during substorms using the FUV instrument on the Imager for Magnetopause-to-Aurora Global Explorer ( IMAGE) spacecraft. The larger of the […]

9. Limitation of egg production in Calanus finmarchicus in the field: a stoichiometric analysis

   The egg production of marine copepods correlates with a range of variables, including the availability of organic carbon (C), nitrogen (N) and the polyunsaturated fatty acids (PUFAs) 20:5(n-3) (EPA) and […]

10. Egg production and associated losses of carbon, nitrogen and fatty acids from maternal biomass in Calanus finmarchicus before the spring bloom

    We present concurrent data on ingestion, egg production and the loss of maternal biomass in pre-spring bloom female Calanus finmarchicus incubated under conditions representative of those in situ in the […]

11. On the effects of divide migration, along-ridge flow and basal sliding on isochrones near an ice divide

    Radar layer geometry in divide areas is strongly influenced by the operation of the Raymond effect, which causes upwarping of the layers as a consequence of the nonlinear rheology of […]

12. On the effects of anisotropic rheology on ice flow, internal structure, and the age-depth relationship at ice divides

    We use numerical modeling with a full-system Stokes solver to elucidate the effects of nonlinear rheology and strain-induced anisotropy on ice flow at ice divides. We find that anisotropic rheology […]
