Title | Numerical experiments on vapor diffusion in polar snow and firn and its impact on isotopes using the multi-layer energy balance model Crocus in SURFEX v8.0 | Type | Journal | ||
Year | 2018 | Publication | Geoscientific Model Development | Abbreviated Journal | |
Volume | 11 | Issue | 6 | Pages | 2393-2418 |
Keywords | |||||
Abstract | Abstract. To evaluate the impact of vapor diffusion on isotopic composition variations in snow pits and then in ice cores, we introduced water isotopes in the detailed snowpack model Crocus. At each step and for each snow layer, (1) the initial isotopic composition of vapor is taken at equilibrium with the solid phase, (2) a kinetic fractionation is applied during transport, and (3) vapor is condensed or snow is sublimated to compensate for deviation to vapor pressure at saturation. We study the different effects of temperature gradient, compaction, wind compaction, and precipitation on the final vertical isotopic profiles. We also run complete simulations of vapor diffusion along isotopic gradients and of vapor diffusion driven by temperature gradients at GRIP, Greenland and at Dome C, Antarctica over periods of 1 or 10 years. The vapor diffusion tends to smooth the original seasonal signal, with an attenuation of 7 to 12% of the original signal over 10 years at GRIP. This is smaller than the observed attenuation in ice cores, indicating that the model attenuation due to diffusion is underestimated or that other processes, such as ventilation, influence attenuation. At Dome C, the attenuation is stronger (18%), probably because of the lower accumulation and stronger ?18O gradients. |

Title | Evidence for a differential sea level rise between hemispheres over the twentieth century | Type | Journal | ||
Year | 2014 | Publication | Geophysical Research Letters | Abbreviated Journal | |
Volume | 41 | Issue | 5 | Pages | 1639-1643 |
Keywords | climate change geodesy GPS land motion sea level tide gauge | ||||
Abstract | AbstractTide gauge records are the primary source of sea level information over multidecadal to century timescales. A critical issue in using this type of data to determine global climate-related contributions to sea level change concerns the vertical motion of the land upon which the gauges are grounded. Here we use observations from the Global Positioning System for the correction of this vertical land motion. As a result, the spatial coherence in the rates of sea level change during the twentieth century is highlighted at the local and the regional scales, ultimately revealing a clearly distinct behavior between the Northern and the Southern Hemispheres with values of 2.0 mm/yr and 1.1 mm/yr, respectively. Our findings challenge the widely accepted value of global sea level rise for the twentieth century. | ||||

Title | Seasonal Meandering of the Polar Front Upstream of the Kerguelen Plateau | Type | Journal | ||
Year | 2018 | Publication | Geophysical Research Letters | Abbreviated Journal | |
Volume | 45 | Issue | 18 | Pages | 9774-9781 |
Keywords | Antarctic Polar Front functional principal component analysis Kerguelen Plateau Southern Indian Ocean Southern Ocean fronts | ||||
Abstract | The location of the Antarctic Polar Front (PF) is mapped in the Southern Indian Ocean by decomposing the shape of temperature and salinity profiles into vertical modes using a functional Principal Component Analysis. We define the PF as the northernmost minimum of temperature at the subsurface and represent it as a linear combination of the first three modes. This method is applied on an ocean reanalysis data set and on in situ observations, revealing a seasonal variability of the PF latitudinal position that is most pronounced between the Conrad Rise and the Kerguelen Plateau. This shift coincides with variations in the transport across the Northern Kerguelen Plateau. We suggest that seasonal changes of the upper stratification may drive the observed variability of the PF, with potentially large implications for the pathways and residence time of water masses over the plateau and the phytoplankton bloom extending southeast of the Kerguelen Islands. | ||||
