Response of Antarctic Circumpolar Current Jets to Southern Hemisphere Westerly Shifts During the 21st Century

Journal of Geophysical Research: Oceans, Volume 130, Issue 12, December 2025.
Abstract The Antarctic Circumpolar Current (ACC) is strongly influenced by the Southern Hemisphere Westerly winds (SHW), which is projected to intensify and shift poleward under increasing anthropogenic radiative forcing. However, the extent of ACC frontal jet responses to these changes remains uncertain. Using simulations from two CMIP6 (Coupled Model

Geoid anomalies and fracture zones in the Pacific Ocean [PDF]

The high degree and order geoid field in the Pacific is a superposition of fracture zone anomalies and hot-spot swell anomalies. A two-dimensional spectral analysis of this field reveals a very strong north-south wavenumber contribution with a dominant ...

Converting NAD83 GPS heights into NAVD88 elevations with LVGEOID, a hybrid geoid height model for the Long Valley volcanic region, California [PDF]

, 2008
A GPS survey of leveling benchmarks done in Long Valley Caldera in 1999 showed that the application of the National Geodetic Survey (NGS) geoid model GEOID99 to tie GPS heights to historical leveling measurements would significantly underestimate the

The Sea Surface Height Spectrum of Internal Waves

Journal of Geophysical Research: Oceans, Volume 130, Issue 12, December 2025.
Abstract Internal waves and geostrophic motions contribute to sea surface height (SSH) variability at scales order 100 km and smaller. Although geostrophic motions have a well‐defined contribution in SSH, the internal wave contribution is complex and small enough to be confounded with noise.

Precision study of satellite levelling with using various models of geoid

E3S Web of Conferences, 2018
The main purpose of this study is comparison of orthometric heights of measuring points and the accuracy of these heights depending on selected geoid model and measurement method. In addition, for better understanding of the essence of conducted research,

Satellite techniques for determining the geopotential for sea-surface elevations [PDF]

, 1984
Spaceborne altimetry with measurement accuracies of a few centimeters which has the potential to determine sea surface elevations necessary to compute accurate three-dimensonal geostrophic currents from traditional hydrographic observation is discussed ...

Sedimentology and geomorphology of tufa barrages on rock coast shore platforms

Sedimentology, Volume 72, Issue 7, Page 2173-2200, December 2025.
ABSTRACT Despite tufa deposits being widely distributed and increasingly recognised globally on rock coasts, their distribution in the tidal frame and geomorphology is poorly understood. The distribution, sedimentology and geomorphology of tufa barrages on supratidal rock coasts are assessed and their controls established.

Multiband raster datasets in order to use global gravimetric models for the territory of the Republic of Kosova [PDF]

Micro, Macro & Mezzo Geoinformation, 2021
Due to current situation in Kosova with the national geoid, which is still under development, utilization of global EGM’s is more than necessary. In this research, multiband raster datasets with 1km spatial resolution of existing EGM 2008, 1996, and ...
