Satellite altimetry, satellite gravimetry, and in-situ subsurface salinity temperature profiles are used to investigate the total, barystatic, steric sea level variations in Baltic Sea, respectively. To estimate level, density weighted deeper layers prevent overestimation of their contribution. We show that sum barystatic components exhibits excellent cross correlation (0.9) with altimetry also...

The satellite mission GRACE (Gravity Recovery and Climate Experiment) provides monthly solutions of the global gravity field of the Earth. Temporal variations in gravity reflect mass redistributions over the Earth. Those mass movements are caused by physical phenomena such as ice sheet dynamics, accumulation of hydrological masses over land, the dynamics in the solid Earth and the dynamics in t...

The dynamic stability of the Antarctic Ice Sheet is one largest uncertainties in projections future global sea-level rise. Essential for improving ice sheet evolution understanding ongoing trends and accelerations mass loss context dynamics. Here, we examine change from 2002 to 2020 using data GRACE (Gravity Recovery Climate Experiment; 2002–2017) its follow-on GRACE-FO (2018-present) satellite...

Coastal Fars gravimetry project in Fars province was carried out to find the buried salt domes and to determine characteristics of faults in this area. The Lavarestan structure was covered by 4203 gravimetry stations in a regular grid of 1000*250 m. Depth structural model of this anticline made in previous studies was based on geological evidences and structural geology measurements. In order t...

One way of thermal stability methods and ablation improving for polyurethane elastomers to solid propellant rocket insulation, is using of fillers with high ablation property such as silica particles. In this research, first polyurethane-silica composites (16, 25 and 38% by weight) and polyurethane-silica nanocomposites (5, 10, 16 and 25% by weight) were prepared and then interaction, morpholog...

I) UVAL’S EXAMINATION by thermal gravimetry of nearly 1000 chemical precipitates (1) had suggested to one of us the employment of thermal methods in the analysis of concretions of biologic origin. Indeed, use of the thermogravimetric technic was made in conjunction with infrared spectrophotometry (2) and X-ray crystallography (3) in investigations concerning tile formation mechanism of renal tr...

Delay of the Global Positioning System (GPS) signal due to atmospheric water vapor is a major source of error in GPS surveying. Improved vertical accuracy is important for sea level and polar isostasy measurements, geodesy, normal fault motion, subsidence, earthquake studies, air and ground-based gravimetry, ice dynamics, and volcanology. We conducted a GPS survey using water vapor radiometers ...

A new class of microporous adsorbents, the metal-organic frameworks was recently developed. Despite their promising characteristics, not much is known about their adsorption behaviour, certainly for mixtures. In this work, vapour and gas phase adsorption and separation of (i) linear and branched alkanes, cyclohexane and benzene, (ii) C8 alkylaromatic compounds and (iii) CO2 and CH4 is studied o...

The poorly known correction for the ongoing deformation of the solid Earth caused by glacial isostatic adjustment (GIA) is a major uncertainty in determining the mass balance of the Antarctic ice sheet from measurements of satellite gravimetry and to a lesser extent satellite altimetry. In the past decade, much progress has been made in consistently modeling ice sheet and solid Earth interactio...
