Sensitivity of the dynamics of Pine Island Glacier, West Antarctica, to climate forcing for the next 50 years The Cryosphere DOI 10.5194/tc-8-1699-2014 17 September 2014 The authors employ a 3D, higher-order model to simulate the evolution of Pine Island Glacier over the next 50 yr in response to changes in its surface mass balance, the position of its calving front and ocean-induced ice shelf melting.

Tropospheric ozone increases over the southern Africa region: bellwether for rapid growth in Southern Hemisphere pollution? Atmospheric Chemistry and Physics DOI 10.5194/acp-14-9855-2014 17 September 2014 Increases in tropospheric ozone based on ozonesonde records (early 1990s to 2008) over subtropical stations in Irene (South Africa) and Réunion have been reported. Over Irene a large increase in the urban-influenced boundary layer (BL) was also observed. This paper shows that the Irene BL trend is at least partly due to a gradual change in the sonde launch times. Read more
Numerical studies on the Impact of the Last Glacial Cycle on recent borehole temperature profiles: implications for terrestrial energy balance Climate of the Past DOI 10.5194/cp-10-1693-2014 10 September 2014 In this paper, the authors provide the first estimate of the impact of the development of the Laurentide ice sheet on the estimates of energy and temperature reconstructions from measurements of terrestrial borehole temperatures in North America.

Release of hydrogen peroxide and antioxidants by the coral Stylophora pistillata to its external milieu Biogeosciences DOI 10.5194/bg-11-4587-2014 1 September 2014 This paper presents a laboratory characterisation of hydrogen peroxide (H2O2) and antioxidant activity release kinetics by intact, non-stressed Stylophora pistillata. Experimenting with bleached and non-bleached corals and different stirring speeds, the authors explored the sources and modes of H2O2 and antioxidant release. Read more
Protection against lightning at a geomagnetic observatory Geoscientific Instrumentation, Methods and Data Systems DOI 10.5194/gi-3-135-2014 27 August 2014 The Sinji Vrh Geomagnetic Observatory, built on the brow of Gora, the mountain above Ajdovščina in Slovenia, is very often struck by lightning. This manuscript analyses the formation of lightning in the area and ways of protecting the observatory. Read more
Molecular corridors and kinetic regimes in the multiphase chemical evolution of secondary organic aerosol Atmospheric Chemistry and Physics DOI 10.5194/acp-14-8323-2014 20 August 2014 Based on molecular identification of secondary organic aerosol (SOA) oxidation products, the authors show here that the chemical evolution of SOA from a variety of volatile organic compound precursors adheres to characteristic “molecular corridors” with a tight inverse correlation between volatility and molar mass.

Elevation and elevation change of Greenland and Antarctica derived from CryoSat-2 The Cryosphere DOI 10.5194/tc-8-1539-2014 20 August 2014 This study focuses on the present-day surface elevation of the Greenland and Antarctic ice sheets. Based on 3 years of CryoSat-2 data acquisition the authors derived new elevation models (DEMs) as well as elevation change maps and volume change estimates for both ice sheets. Read more
Diverse coral communities in mangrove habitats suggest a novel refuge from climate change Biogeosciences DOI 10.5194/bg-11-4321-2014 19 August 2014 This paper characterises the first natural, non-reef coral refuge from thermal stress and ocean acidification and identifies resiliency factors for mangrove–coral habitats.

MOMBA 1.1 – a high-resolution Baltic Sea configuration of GFDL’s Modular Ocean Model Geoscientific Model Development DOI 10.5194/gmd-7-1713-2014 18 August 2014 We present a new coupled ocean-circulation–ice model configuration of the Baltic Sea. The model features, contrary to most existing configurations, a high horizontal resolution of 1 nautical mile (1.85 km), which is eddy-resolving over much of the domain.
