Ground-based observations of Antarctic clouds using a Rayleigh LiDAR at Davis (69S, 78E). Davos Atmosphere and Cryosphere Assembly 2013, Davos, Switzerland, 8-12 July 2013, 2013 (Ref: 15129)
Category 3: Verbal presentation

A Rayleigh lidar at Davis, Antarctica (69S, 78E) has made intermittent observations of clouds for the last few years. Radiosondes and a co-located wind-profiling radar provide additional data with which to characterise the clouds and the environment in which they exist.

Quantifying the role of orographic gravity waves in influencing polar stratospheric cloud occurrence. Davos Atmosphere and Cryosphere Assembly 2013, Davos, Switzerland, 8-12 July 2013, 2013 (Ref: 15130)
Category 3: Poster

Polar Stratospheric Cloud (PSC) composition class information is extracted from the Cloud-Aerosol Lidar with Orthogonal Polarization (CALIOP) curtains for four Antarctic PSC seasons (2007 - 2010) and four Arctic PSC seasons (2006/07 - 2009/10). Orographic gravity wave (OGW)…

The 2013 Antarctic ozone hole. Atmospheric Composition and Chemistry Observations and Modelling Conference incorporating the Cape Grim Annual Science Meeting, Aspendale, Victoria, Australia 27-29 November 2013, 2013 (Ref: 15135)
Category 3: Conference paper

The 2013 ozone hole was relatively small, with about 15-17 ozone holes out of the last 20 (1994-2013) having been bigger/deeper (depending on the metric used), and only 2-4 having been smaller (2002, 2004, 2010, 2012).

Atmospheric chemistry measurements over the East Antarctic during the SIPEX II cruise in polar spring 2012. Davos Atmosphere and Cryosphere Assembly 2013, Davos, Switzerland, 8-12 July 2013, 2013 (Ref: 15128)
Category 3: Verbal presentation

Bromine explosion events that occur over first year sea ice in the polar spring cause mercury deposition and dramatically alter the oxidative capacity of the polar boundary layer. Atmospheric chemical measurements made during the Sea Ice Physics and Ecosystems eXperiment (SIPEX II)…

Calculations of Ozone Loss Rates within the Antarctic “Ozone Hole” using Quasi-Lagrangian Measurements of Ozone made during the Concordiasi Long-duration Balloon Campaign. Quadrennial Ozone Symposium 2012, Toronto, Canada, 27-31 August, 2012 (Ref: 15105)
Category 3: Verbal presentation

Considerable progress in our understanding of the causes of polar stratospheric ozone loss has been made during the past two decades. However, model calculations are still limited by uncertainties in both chemical and dynamical factors.

Tropical tropopause layer processes driving stratospheric composition - focus on polar ozone relevant species. XXXII SCAR and Open Science Conference, Portland, Oregon, USA, 13-25 July 2012, 2013 (Ref: 15104)
Category 3: Verbal presentation

The composition of the stratosphere is driven by transport, temperatures and processes in the tropical tropopause layer – this has implications for ozone, radiation, and surface climate. The properties of the tropical tropopause layer have changed in recent decades, e.g.

Backward movement of ozone minimum position as a possible consequence of ozone recovery over Antarctica. American Geophysical Union 2013 Fall Meeting, San Francisco USA, 9-12 December 2013, 2013 (Ref: 15136)
Category 3: Poster

The ozone hole over Antarctica is formed inside polar stratospheric vortex, which is under influence of large-scale planetary waves. The Quasi-stationary wave (QSW) in the spring Southern Hemisphere (SH)…

Influences of circulation changes on the distribution of Antarctic stratospheric ozone. Davos Atmosphere and Cryosphere Assembly 2013, Davos, Switzerland, 8-12 July 2013, 2013 (Ref: 15132)
Category 3: Poster

The cause of seasonal trends in the zonal asymmetry of the total ozone column (TOC) at high southern latitudes are examined. Using ERA-Interim assimilated meteorological data, we examine characteristics of extra-tropical Rossby waves…

Improving gravity wave drag parameterization in climate models. Davos Atmosphere and Cryosphere Assembly 2013, Davos, Switzerland, 8-12 July 2013, 2013 (Ref: 15131)
Category 3: Poster

Links between changes in the southern polar stratosphere and tropospheric climate have been identified in both modelling and observational studies, highlighting the importance of an accurate stratosphere in climate models. However…

High-resolution Antarctic observations of the stratospheric influence on the troposphere. 3rd International Conference on Earth System Modelling, Hamburg, Germany, 17-21 September 2012, 2012 (Ref: 15127)
Category 3: Poster

The upper troposphere and lower stratosphere (UTLS) is a highly coupled region of the atmosphere where radiation, dynamics, clouds and chemical processes interact on a wide variety of spatial and temporal scales. We use a suite of instruments at Davis, Antarctica (69S, 78E)…

Fitting Euphausia superba into Southern Ocean food-web models: a review of data sources and their limitations. CCAMLR Science, 2012 (Ref: 15092)
Category 1: Peer-reviewed literature

This paper aims to provide the overview needed to include krill in food-web models and to guide modellers to key sources of data. It describes the strengths of each method of sampling krill, i.e. with nets (for historical time series, demographic information and live krill), acoustics (distribution…

Aesthetic value in Antarctica: beautiful or sublime? The Polar Journal, 2011 (Ref: 15024)
Category 1: Peer-reviewed literature

Protection of the wilderness and aesthetic values of Antarctica is mandated by the Protocol on Environmental Protection to the Antarctic Treaty, the “Madrid Protocol,” which came into force in 1998. Despite the passage of over 13 years…
