TL;DR: In this article, the authors performed a global-scale analysis of the impact of water withdrawals on water storage variations, using the global water resources and use model WaterGAP, and concluded that water withdrawals at the scale of the whole Mississippi basin cannot be monitored by GRACE.

TL;DR: Very long baseline interference (VLBI) has proven to be a primary space-geodetic technique by determining precise coordinates on the Earth, by monitoring the variable Earth rotation and orientation with highest precision, and by deriving many other parameters of the Earth system as discussed by the authors.

TL;DR: In this article, the authors summarize observations of sea level variations, globally and regionally, during the 20th century and the last 2 decades, during which the global mean sea level rose at rates of 1.7mm/yr and 3.2mm/r respectively, as a result of both increase of ocean thermal expansion and land ice loss.

TL;DR: In this paper, a generic model that integrates results from physical modeling is proposed for the thermal-mechanical evolution of crustal orogenic belts and for its implication in controlling the transition between the different phases of the Orogenic cycle.

TL;DR: Geocenter motion is intimately related to the realization of the International Terrestrial Reference Frame (ITRF) origin, and, in various ways, affects many of our measurement objectives for global change monitoring as discussed by the authors.

TL;DR: In this article, 40Ar/39Ar dating on the main tectonic boundaries of the Anatolide-Tauride-Armenian (ATA) block in Eastern Turkey, Armenia and Georgia provide temporal constraints of subduction and accretion on both sides of this small continental block, and final collisional history of Eurasian and Arabian plates.

TL;DR: In this paper, the relative motion of India and Asia for the last 100 million years is reviewed and a revised reconstruction for the India-Antarctica-Africa-North America-Eurasia plate circuit based on published motion histories.

TL;DR: In this article, three major shortening episodes are identified: a pre-Priabonian deformation D1 (N-S shortening), supposedly linked with the Pyrenean-Provence orogeny, and two Alpine shortening events D2 (N to NW-directed) and D3 (W-directed).

TL;DR: In this article, a multi-approach approach was proposed to estimate pressure temperature (P-T ) paths to understand the kinematic of burial and exhumation of continental units in the French Western Alps.

TL;DR: The role of reactivated Precambrian shear zones and major terrain boundaries in the development of the Potiguar Basin from the Cretaceous to the Cenozoic was investigated in this article.

TL;DR: In this paper, the authors examined the recent evolution of the Greenland ice sheet and its six major drainage basins using laser altimetry data acquired by the ICESat, covering the period September-November 2003 to February-March 2008.

TL;DR: In this paper, a joint least squares inversion of load-induced GPS site displacements, GRACE gravimetry and simulated ocean bottom pressure from the finite element sea-ice ocean model was used to estimate weekly surface loading variations.

TL;DR: In this article, a Kalman filter and smoother estimation procedure is applied to the original GRACE observations (level-1B) to calculate daily solutions as part of the gravity field model ITG-Grace2010.

TL;DR: In this article, the break up of Gondwana with oceanisation between South America (SAM) and Antarctica (ANT), together with the break off of "Andean" geodynamical units (GDUs) crossing the Pacific, are reconstructed from Jurassic (165-Ma) to present.

TL;DR: In this article, the hydrological contribution to polar motion is investigated and evaluated at seasonal and intra-seasonal time scales using the recovered degree-2 harmonic coefficients from all GRACE spherical harmonic coefficients and hydrologogical models data with the same filter smoothing and recovering methods, including the Global Land Data Assimilation Systems (GLDAS) model, Climate Prediction Center (CPC) model and National Centers for Environmental Prediction/National Center for Atmospheric Research (NCEP/NCAR) reanalysis products and European Center for Medium-Range Weather Forecasts (ECMWF

TL;DR: In this paper, the mass-induced sea level variability and the net mass transport between Mediterranean Sea and Black Sea are derived for the interval between August 2002 and July 2008 from satellite-based observations and from model data.

TL;DR: This article applied a statistical filtering approach to reduce noise in the GRACE data by confining their investigations to GRACE coefficients containing a statistically significant linear trend, which results in a non-isotropic smoothing of the gravity fields.

TL;DR: In this article, a combined estimation of a global ocean tide model based on satellite altimetry and GRACE observations is presented, where the capability of GRACE to sense particular tidal constituents is elaborated and an approach to estimate tidal constituents from GRACE is outlined.

TL;DR: In this paper, the ability of the GRACE gravimetry mission and Jason-1 altimetry to resolve ice and glacier induced contributions to sea level rise, by means of a fingerprint method, was studied.

TL;DR: In this paper, the authors used GPS data acquired in the last 10 years by a fairly dense network of permanent GPS stations located in Central and Northern Italy to reconstruct the present horizontal velocity field in the study area and to evaluate the coseismic and postseismic effects of the recent L’Aquila earthquake (April 6, 2009 Mw = 6.3).

TL;DR: In this article, the South Armorican Shear Zone, a major structural feature of the Armorican Massif (France), is outlined by the presence of mylonitic rocks cropping out mostly in open quarries.

TL;DR: The Charilehue volcanic sequences represent the westernmost products of an incipient and poorly evolved arc that migrated and expanded to the foreland, initially coexisting with an extensional setting inherited from late Oligocene times as discussed by the authors.

TL;DR: In this paper, the capabilities of the method of multichannel singular spectrum analysis (MSSA) to extract periodic signals from the Gravity Recovery and Climate Experiment (GRACE) gravity field solutions are studied.

TL;DR: In this paper, the authors used GPS data from 14 years at 208 stations world-wide to estimate admittance factors for the associated load deformation time series in order to determine how well the model-based deformation fits to real data.

TL;DR: In this paper, a new mechanism for the removal of the North China Craton is proposed, which is based on the folding of the lithosphere during the Late Triassic through Jurassic period.

TL;DR: The term "hot spot" was coined by as mentioned in this paper to refer to volcanic regions considered to be anomalous in the then-new plate tectonic paradigm and carried with it the implication that volcanism is emplaced by a single, spatially restricted, mongenetic melt-delivery system, assumed to be a mantle plume, and that the source is unusually hot.

TL;DR: The SPP 1257 (Mass Distribution and Mass Transport in the Earth System) as discussed by the authors was established to facilitate integrated analysis of these data, to improve our knowledge about several transport processes within the Earth system and to investigate their interactions.

TL;DR: The Binalud Mountains as mentioned in this paper are located in the south of the Kopeh Dagh as a transitional zone between the Alborz and Central Iran zones and the Palaeotethys suture of the north Iran is located in this area.

TL;DR: In this paper, a combination of the least squares, an autoregressive (AR) model and a Kalman filter (LS + AR + Kalman) was employed for short-term prediction of the earth orientation parameters (the length of day (LOD), UT1-UTC and polar motion).

TL;DR: In this paper, the authors assessed monthly grace solutions, hydrological and hydro-meteorological data, and their respective combinations to ascertain their uncertainties, and identified, removed, and replaced unphysical outliers in grace data.
