1. Latest Neoproterozoic to Mid-Cambrian age for the main deformation phases of the Transantarctic Mountains: new stratigraphic and isotopic constraints from the Pensacola Mountains, Antarctica

   New isotopic ages and a fresh understanding of stratigraphic relations among siliciclastic strata in the Pensacola Mountains along the northern margin of the East Antarctic craton result in removal of […]

2. Ozone loss episodes in the free Antarctic troposphere, suggesting a possible climate feedback

   Sudden loss of tropospheric ozone well above the boundary layer was observed on three occasions at two coastal sites in Antarctica in spring 1995. Back trajectories show that the air […]

3. Improvements to the accuracy of zenith-sky measurements of total ozone by visible spectrometers II: use of daily air-mass factors

   Ozone at Faraday in Antarctica is measured by a ground-based visible spectrometer. Total ozone is deduced from the slant column measurements by means of calculated air-mass factors (AMFs), which have […]

4. Improvements to the accuracy of measurements of NO2 by zenith-sky visible spectrometers. II: Errors in zero using a more complete chemical model

   Using a flexible chemical box model with full heterogeneous chemistry, intercepts of chemically modified Langley plots have been computed for the 5 years of zenith-sky NO2 data from Faraday in […]

5. Increased stratospheric greenhouse gases could delay recovery of the ozone hole and of ozone loss at southern mid-latitudes

   Stratospheric H2O is increasing, and may be responsible for a large part of the observed cooling of the lower stratosphere. Further cooling will lead to more PSCs in the edge […]

6. The risk of large volcanic eruptions and the impact of this risk on future ozone depletion

   Ozone depletion at mid-latitudes is caused by reactivehalogens from man-made halocarbons. The stratosphericsulphate aerosol which follows large volcaniceruptions enhances (multiplies) this ozone depletion(it has no effect on ozone without halocarbons). […]

7. Long-term trends in geomagnetic daily variation

   Long-term changes in the magnetic environment of the Earth are of interest to those studying climate change. To this end we examine long-term changes in daily variation as derived from […]

9. Managing and forecasting squid fisheries in variable environments

   Squid are short-lived ecological opportunists which generally have a lifespan of about 1 year. Their populations are labile and recruitment variability is driven, to a greater or lesser extent, by […]

10. Lower ionospheric modification by lightning-EMP: simulation of the night ionosphere over the United States

    It has recently been suggested that successive intense lightning‐electromagnetic pulse (EMP) events could cause significant large‐scale changes to the properties of the nighttime lower ionosphere. In order to examine this […]

11. The variability of Joule heating and its effects on the ionosphere and thermosphere

    A considerable fraction of the solar wind energy that crosses the magnetopause ends up in the high-latitude thermo sphere-io no sphere system as a result of Joule heating, the consequences […]
