Inferring palaeo-accumulation records from ice-core data by an adjoint-based method: application to James Ross Island’s ice core
Ice cores contain a record of snow precipitation that includes information about past atmospheric circulation and mass imbalance in the polar regions. We present a novel approach to reconstruct a climatic record – by both optimally dating an ice core and deriving from it a detailed accumulation history – that uses an adjoint-based method. The motivation of our work is the recent application of ...
متن کاملTides of the Ross Sea and Ross Ice Shelf cavity
Two new ocean tide models for the Ross Sea including the ocean cavity under the Ross Ice Shelf, are described. The optimum model for predicting ice shelf surface height variability is based on assimilation of gravimetry-derived tidal constituents from the Ross Ice Shelf. Synthetic aperture radar interferograms provide an independent test of model performance. The standard deviation of tide heig...
متن کاملEvaluation of Selected Basic Soil Properties at the James Ross Island (antarctica)
VLČEK VÍTĚZSLAV. 2016. Evaluation of Selected Basic Soil Properties at the James Ross Island (Antarctica). Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 64(3): 919–926. This study attempts to summarize the basic soil properties of the selected places in the deglaciated areas on the James Ross Island (Antarctica). James Ross Island is a large island near the north-easte...
متن کاملAntifreeze thermal ice core drilling: an effective approach to the acquisition of ice cores
Antifreeze thermal electric drills have a long history of ice drilling in temperate, subpolar and polar glaciers. Shallow, intermediate and deep ice cores have been obtained in Arctic, Antarctic and on high elevation glaciers. Many merits and drawbacks of antifreeze thermal technology have been discovered over the past 25 years. A modified version of the antifreeze thermal electric ice coring d...
متن کاملMicroparticle Analysis of the Ross Ice Shelf Q - 13 Core and Preliminary Results from the J - 9 Core
The concentration and size distribution of microparticles are measured on the Ross Ice Shelf at three sites : Q-13, base camp, and J-9. Results from the analysis of 2 611 samples representing the 100 m core from site Q-13 are presented. Increasing particle concentrations since 1800 are interpreted as a reflection of the gradual movement of the Q-13 drill site northward toward the Ross Sea under...
