Short- and long-term consequences of larval stage exposure to constantly and ephemerally elevated carbon dioxide for marine bivalve populations Biogeosciences DOI 10.5194/bg-10-2241-2013 5 April 2013 Experiments were performed to assess the short-term (days) and long-term (months) consequences of larval stage exposure to varying CO2 concentrations for calcifying bivalves. The findings suggested that high CO2 has a cascading negative physiological impact on bivalve larvae stemming in part from lower calcification rates. Read more
Ice-shelf buttressing and the stability of marine ice sheets The Cryosphere DOI 10.5194/tc-7-647-2013 4 April 2013 Ice-shelf buttressing and the stability of marine-type ice sheets are investigated numerically. Buttressing effects are analysed for a situation where a stable grounding line is located on a bed sloping upwards in the direction of flow. Read more
Interpreting muon radiographic data in a fault zone: possible application to geothermal reservoir detection and monitoring Geoscientific Instrumentation, Methods and Data Systems DOI 10.5194/gi-2-145-2013 27 March 2013 In this report, the data taken by Tanaka et al. (2011) are reanalyzed to estimate the porosity distribution as a function of a distance from the fault gouge. The result shows a similar pattern of the porosity distribution as measured by borehole sampling at Nojima fault. Read more
The influence of climate change on flood risks in France – first estimates and uncertainty analysis Natural Hazards and Earth System Sciences DOI 10.5194/nhess-13-809-2013 27 March 2013 This paper proposes a methodology to project the possible evolution of river flood damages due to climate change, and applies it to mainland France.

Mechanisms causing reduced Arctic sea ice loss in a coupled climate model The Cryosphere DOI 10.5194/tc-7-555-2013 26 March 2013 The fully coupled climate model HadGEM1 produces one of the most accurate simulations of the historical record of Arctic sea ice seen in the IPCC AR4 multi-model ensemble. In this study, we examine projections of sea ice decline out to 2030, produced by two ensembles of HadGEM1 with natural and anthropogenic forcings included. Read more
Meteorological observations on the northern Chilean coast during VOCALS-REx Atmospheric Chemistry and Physics DOI 10.5194/acp-13-3409-2013 25 March 2013 Surface coastal observations from two automatic weather stations at Paposo (~25° S) and radiosonde observations at Paposo and Iquique (~20° S) were carried out during VOCALS-REx (VAMOS Ocean-Cloud-Atmosphere-Land Study Regional Experiment).

Host model uncertainties in aerosol radiative forcing estimates: results from the AeroCom Prescribed intercomparison study Atmospheric Chemistry and Physics DOI 10.5194/acp-13-3245-2013 20 March 2013 In this AeroCom Prescribed intercomparison study we systematically isolate and quantify host model uncertainties on aerosol forcing experiments through prescription of identical aerosol radiative properties in twelve participating models.

The CM SAF SSM/I-based total column water vapour climate data record: methods and evaluation against re-analyses and satellite Atmospheric Measurement Techniques DOI 10.5194/amt-6-765-2013 19 March 2013 The European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT) Satellite Application Facility on Climate Monitoring (CM SAF) aims at the provision and sound validation of well documented Climate Data Records (CDRs) in sustained and operational environments. In this study, a total column water vapour path climatology from CM SAF is presented and inter-compared to water vapour data records from various data sources. Read more
Direct linking of Greenland and Antarctic ice cores at the Toba eruption (74 ka BP) Climate of the Past DOI 10.5194/cp-9-749-2013 19 March 2013 In this work we suggest a direct synchronization of Greenland and Antarctic ice cores at the Toba eruption based on matching of a pattern of bipolar volcanic spikes. Annual layer counting between volcanic spikes in both cores allows for a unique match. Read more
Local and global perspectives on the virtual water trade Hydrology and Earth System Sciences DOI 10.5194/hess-17-1205-2013 19 March 2013 Recent studies on fluxes of virtual water are showing how the global food and goods trade interconnects the water resources of different and distant countries, conditioning the local water balances. This paper presents and discusses the assessment of virtual water fluxes between a single country and its network of trading partners, delineating a country’s virtual water budget in space and time (years 1986–2010).
