2. Plasma progesterone concentrations measured using a enzyme-linked immunosorbent assay useful for diagnosing pregnancy in harbour seal (Phoca vitulina)

   Wild-caught female harbor seals (Phoca vitulina) were classified as sexually mature or immature on the basis of standard body length (< 125 cm immature, > 125 cm mature) and plasma […]

3. Widespread Antarctic glaciation during the Late Eocene

   Marine sedimentary rocks drilled on the southeastern margin of the South Orkney microcontinent in Antarctica (Ocean Drilling Program Leg 113 Site 696) were deposited between ∼36.5 Ma to 33.6 Ma, […]

4. A new ionospheric electron precipitation module coupled with RAM-SCB within the geospace general circulation model

   Electron precipitation down to the atmosphere due to wave-particle scattering in the magnetosphere contributes significantly to the auroral ionospheric conductivity. In order to obtain the auroral conductivity in global MHD […]

5. Climate forcing for dynamics of dissolved inorganic nutrients at Palmer Station, Antarctica: An interdecadal (1993-2013) analysis

   We analyzed 20 years (1993–2013) of observations of dissolved inorganic macronutrients (nitrate, N; phosphate, P; and silicate, Si) and chlorophyll a (Chl) at Palmer Station, Antarctica (64.8°S, 64.1°W) to elucidate how […]

6. Ice-flow reorganization in West Antarctica 2.5 kyr ago dated using radar-derived englacial flow velocities

   We date a recent ice-flow reorganization of an ice divide in the Weddell Sea Sector, West Antarctica, using a novel combination of inverse methods and ice-penetrating radars. We invert for […]

7. Seasonal evolution of the QBO-induced wave forcing and circulation anomalies in the northern winter stratosphere

   Diagnostics of wave-mean-flow and wave-wave interactions in isentropic coordinates are analyzed regarding the mechanisms that govern the Holton-Tan effect (HTE), whereby the tropical quasi-biennial oscillation (QBO) modulates the northern winter […]

8. Edad y origen de la fluorite del yacimiento La Nueva (Cabalango, Cordoba, Argentina) en base a geoquimica de isotopos radiogenicos (Nd y Sm)

   The fluorite mineralization from the La Nueva Mine, has a Sm-Nd age of 130 ± 19 Ma, and thus must be related to the Lower Cretaceous late-Gondwanic extensional and magmatic […]

9. Pioneers of photogrammetry commemorated in Antarctic place-names

   Unique place-names are essential for scientific fieldwork in Antarctica. This shorter contribution describes how duplication of place-names in British Antarctic Territory has been avoided by the systematic naming of geographically […]

10. An experimental study of growth in relation to morphology and shoot water content in maritime Antarctic mosses

    The dependence of shoot growth and growth form on water availability was studied experimentally in six species of maritime Antarctic moss. Under all conditions the largest growth increments were observed […]

11. The distribution and classification of the problematic Fragilaria (Virescens v.) exigua Grun.Fragilaria exiguiformis (Grun.) Lange-Bertalot: a new species or a new genus?

    The nomenclature of the taxon first recorded as Fragilaria (virescens) v. exigua by Grunow in Cleve & Moeller (1878) is examined with regard to the current botanical name, F. exiguiformis […]

12. Whistler-mode propagation: results of model calculations for an inhomogeneous plasma

    Waveforms computed using the new whistler model derived from Maxwell’s equations were analysed. In the calculations, realistic model values for magnetospheric parameters were used. The results accurately described whistler-mode propagation […]
