Gravity surveying is challenging in Antarctica because of its hostile environment and inaccessibility. Nevertheless, many ground-based, airborne shipborne gravity campaigns have been completed by the geophysical geodetic communities since 1980s. We present first modern Antarctic-wide data compilation derived from 13 million points covering an area 10 km2, which corresponds to 73% coverage continent. The remove-compute-restore technique was applied for gridding, facilitated levelling...
Abstract Sea surface topography observations are deduced from an airborne reflectometry experiment. A GNSS (Global Navigation Satellite System) receiver dedicated for was set up aboard the German HALO (High Altitude Long Range) research aircraft. Flights were conducted over Mediterranean about 3500 m above sea level. signal path model divided into large‐ and small‐scale contributions is used phase altimetry. The results depict geoid undulations resolve anomalies of topography. For whole...
Based on the Ice, Cloud and Land Elevation Satellite (ICESat) laser altimetry data, hydrostatic equilibrium (HE) condition for subglacial Lake Vostok, East Antarctica, is evaluated. A digital elevation model (DEM) of ice surface derived by a regional crossover adjustment. The analysis DEM its comparison with GPS ice-surface elevations an based radar data reveal overall accuracy better than ± 0.7 m lake area. combined ice-thickness geoid to determine deviation local height from HE. For large...
Abstract The question whether Antarctica's largest lake, subglacial Lake Vostok, exchanges water is of interdisciplinary relevance but has been undecided so far. We present the potential pathway, outlet location, and threshold height discharge from this lake based on a quantitative evaluation fluid potential. If left it would flow toward Ross Ice Shelf. Discharge occur first to east southern tip lake. At location bedrock 91 ± 23 m higher than hydrostatic equipotential level Vostok. It...
The official national height reference systems in use, apply different definitions of the and zero levels refer to tide gauges epochs. Additionally, treatment permanent is not entirely consistent. This causes differences at decimetre scale, which also vary along borders. "European Alps Geoid Project" (EAlpG) aims harmonize basis for determination Alpine region, including neighbouring lowlands computation a uniform geoid model according European standards positioning.The project based on...
A unified Chart Datum for the whole Baltic Sea is required use of global navigation satellite systems (GNSS) in accurate 3-D bathymetric surveying and navigation, enabling automated shipping with increased efficiency improved maritime safety. So far, zero levels nautical maps were derived from mean sea level (MSL) different local tide gauges. The inherent height datum differences between neighboring map sheets are a fundamental infrastructural obstacle implementing using new cross-border...
Abstract For decades, the residual terrain model (RTM) concept (Forsberg and Tscherning in J Geophys Res Solid Earth 86(B9):7843–7854, https://doi.org/10.1029/JB086iB09p07843 , 1981) has been widely used regional quasigeoid modeling. In commonly remove-compute-restore (RCR) framework, RTM provides a topographic reduction commensurate with spectral resolution of global geopotential models. This is usually achieved by utilizing long-wavelength (smooth) topography known as reference topography....
<p>The D-A-CH geoid project was initiated in 2017 between the national mapping agencies of Germany (BKG), Austria (BEV) and Switzerland (swisstopo), as well regional authorities German federal states Bavaria (LDBV) Baden-Württemberg (LGL), with motivation to better harmonize basis for height determination.</p><p>In these countries, official reference systems that are still use apply different definitions zero levels refer tide gauges...
