S U M M A R Y Wavelet analysis for filtering is used to improve estimation of gravity variations induced by Chandler wobble. This method eliminate noise in superconducting gravimeter (SG) records with bandpass filters derived from Daubechies wavelet. The SG records at four European stations (Brussels, Membach, Strasbourg and Vienna) are analysed in this study. First, the earth tidal constituent...

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...

A two-dimensional numerical model with a space grid of about 14 km is applied to calculate diurnal tidal constituents K1 and O1 in the Arctic Ocean. Calculated corange and cotidal charts show that along the continental slope, local regions of increased sea level amplitude, highly variable phase and enhanced currents occur. It is shown that in these local regions, shelf waves (topographic waves)...

To better understand the influence of stress changes over floating ice shelves on grounded ice streams, we develop a Bayesian method for inferring time-dependent 3-D surface velocity fields from synthetic aperture radar (SAR) and optical remote sensing data. Our specific goal is to observe ocean tide-induced variability in vertical ice shelf position and horizontal ice stream flow. Thus, we con...

Observations of periodic components of measured heads have long been used to estimate aquifer di€usivities. The estimations are often made using well-known solutions of linear di€erential equations for the propagation of sinusoidal boundary ̄uctuations through homogeneous one-dimensional aquifers. Recent ®eld data has indicated several instances where the homogeneous aquifer solutions give incon...

This document gives a brief introduction on the use of TideHarmonics. The package implements harmonic analysis of tidal and sea-level data. Up to 409 different harmonic tidal constituents can be estimated, and daily nodal corrections are implemented by default.Time-varying mean sea-levels can also be used. Section 1 briefly outlines the theory of harmonic tidal analysis. Example code is contain...

Satellite altimetry observations have provided a significant contribution to the understanding of global sea surface processes, particularly allowing for advances in accuracy ocean tide estimations. Currently, almost three decades satellite are available which can be used improve tides by estimation an increased number minor tidal constituents. As models continue improve, especially coastal reg...

This study was conducted to investigate the efficacy of the simultaneous application of near-infrared (NIR) heating and UV irradiation for reducing populations of food-borne pathogens, including Salmonella enterica serovar Typhimurium and Escherichia coli O157:H7 in red pepper powder and to clarify the mechanisms of the lethal effect of the NIR-UV combined treatment. Also, the effect of the com...

Abstract. Tidal data has been used to determine long-term water level alterations. Tides are high-powered and notoriously hard ascertain. analysis prediction need substantial study with the requisite approaches, techniques, tools in conjunction weather parameters natural calamities.
