Geophysical update of the diameter of the Zhamanshin impact structure, Kazakhstan
Meteoritics &Planetary Science, EarlyView.Abstract The rim of the 0.9‐Ma‐old Zhamanshin impact crater in Kazakhstan is considered to be almost completely exposed via a series of hills surrounding a central flat area, indicating an apparent diameter of 14 km. This would make Zhamanshin the second largest impact crater of the Quaternary period. However, the overall geometry of these hills is not

The Datums Transformation for GPS Navigation Measurements Correction
مجلة بغداد للعلوم, 2008 The GPS navigation measurements become more widely used in many civilian and scientific application. All GPS navigation data holds many errors, the main error sources arise from the geodetic Datum variation when user apply the GPS measurements with the ...

Ecology and Evolution, Volume 16, Issue 8, August 2026.Populations of Critically Endangered gharial (Gavialis gangeticus) in Nepal are restricted primarily within or adjacent to protected areas. There are few records of gharial occurrence from the Karnali River and its tributaries outside protected areas in southwestern Nepal but there is very little information available for gharials residing in the ...

Tides of the Midland: From Groundwater Into the River
Hydrological Processes, Volume 40, Issue 8, August 2026.Tides in a river that is NOT influenced by the ocean, is not in the coastal area and is more than 300 m above sea level are caused by groundwater tides. As the phases of the Moon change, the amplitudes of the streamwater oscillations vary synchronously with those of gravitational acceleration.

Transformation of GPS measurements in the Koice hollow into the national geodetic grid [PDF]
Acta Montanistica Slovaca, 1999 The paper deals with transformation procedures observed GPS (Global Positioning System) data from the World Geodetic System WGS-84 into the national grid datum S-JTSK and Bpv. GPS measurements are realized on the geodetic network in the Koice-hollow for

Fortschritte der Physik, Volume 74, Issue 8, August 2026.ABSTRACT We apply the boundary‐only isothermal formulation of finite‐distance weak gravitational deflection to regular black holes, black‐bounces, traversable wormholes, non‐asymptotically flat backgrounds, and static quadrupolar spacetimes. The methodological advance is not a new value for a known bending angle.

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.Abstract Caldera systems commonly experience inner resurgence, which shapes patterns of volcanic activity. However, incomplete reconstructions of past ground deformation can lead to incorrect recognition of precursory signals. The Campi Flegrei caldera (Italy) provides an exceptional opportunity to address this issue as uplifted marine sediments ...

Sedimentology, Volume 73, Issue 5, Page 1378-1402, August 2026.ABSTRACT Tsunami deposits serve as geological records of past events and are essential for understanding the occurrence and dynamics of tsunamis. However, conventional research has largely focused on sandy and boulder deposits, leaving gravel‐dominated tsunami deposits comparatively underexplored; furthermore, their characteristics and formation ...

A note on frame transformations with applications to geodetic datums [PDF]
GPS Solutions, 2003 Rigorous equations in compact symbolic matrix notation are introduced to transform coordinates and velocities between ITRF frames and modern GPS-based geocentric geodetic datums. The theory is general but, after neglecting higher than second-order terms, it is shown that the equations revert to the formulation currently applied in most major ...
