Electric fields at L = 2.5 during geomagnetically disturbed conditions
Read more of: Electric fields at L = 2.5 during geomagnetically disturbed conditionsWe have used observations of the group time delay and Doppler shift of ducted VLF whistler mode signals propagating near L = 2.5 to deduce the azimuthal component of the […]

Long-lasting geomagnetically induced currents and harmonic distortion observed in New Zealand during the 07-08 September 2017 Disturbed Period
Read more of: Long-lasting geomagnetically induced currents and harmonic distortion observed in New Zealand during the 07-08 September 2017 Disturbed PeriodSeveral periods of Geomagnetically Induced Currents (GIC) were detected in the Halfway Bush substation in Dunedin, South Island, New Zealand, as a result of intense geomagnetic storm activity during 06 […]

Growth of microalgae using nitrate-rich brine wash from the water industry
Read more of: Growth of microalgae using nitrate-rich brine wash from the water industrySafe and accepted limits for nitrates in drinking water are exceeded in around one-third of the groundwater bodies in Europe. Whilst anion exchange (AEX) is an effective technology to strip […]

Accumulate or eliminate? Seasonal mercury dynamics in albatrosses, the most contaminated family of birds
Read more of: Accumulate or eliminate? Seasonal mercury dynamics in albatrosses, the most contaminated family of birdsAlbatrosses (Diomedeidae) are iconic pelagic seabirds whose life-history traits (longevity, high trophic position) put them at risk of high levels of exposure to methylmercury (MeHg), a powerful neurotoxin that threatens […]

Status and trends of albatrosses in the French Southern Territories, Western Indian Ocean
Read more of: Status and trends of albatrosses in the French Southern Territories, Western Indian OceanToday albatrosses are threatened worldwide, especially by fishing activities, and many populations are currently in decline. Albatrosses breeding at the French Southern Territories in the south-western Indian Ocean, on the […]

The role of diatom resting spores in pelagic–benthic coupling in the Southern Ocean
Read more of: The role of diatom resting spores in pelagic–benthic coupling in the Southern OceanNatural iron fertilization downstream of Southern Ocean island plateaus supports large phytoplankton blooms and promotes carbon export from the mixed layer. In addition to sequestering atmospheric CO2, the biological carbon […]

Variability of sea salts in ice and firn cores from Fimbul Ice Shelf, Dronning Maud Land, Antarctica
Read more of: Variability of sea salts in ice and firn cores from Fimbul Ice Shelf, Dronning Maud Land, AntarcticaMajor ions were analysed in firn and ice cores located at Fimbul Ice Shelf (FIS), Dronning Maud Land – DML, Antarctica. FIS is the largest ice shelf in the Haakon […]

Molecular data suggest long-term in situ Antarctic persistence within Antarctica’s most speciose plant genus, Schistidium
Read more of: Molecular data suggest long-term in situ Antarctic persistence within Antarctica’s most speciose plant genus, SchistidiumFrom glacial reconstructions it is clear that Antarctic terrestrial life must have been extremely limited throughout Quaternary glacial periods. In contrast, recent biological studies provide clear evidence for long-term in […]

Atmospheric and space research from polar regions
Read more of: Atmospheric and space research from polar regionsThe polar regions are unique laboratories for carrying out research on both the atmosphere and the near-Earth space environment. The relatively undisturbed conditions help us explore phenomena like the greenhouse […]

Review and revision of measurements of stratospheric N2O5
Read more of: Review and revision of measurements of stratospheric N2O5Measurements of N2O5 in the stratosphere and of its spectrum at 1240 cm−1 in the laboratory are reviewed. Errors in previous publications about N2O5 are discussed briefly. The earliest stratospheric […]
