We first review some history of the Global Geodynamics Project (GGP), particularly in the progress of ground-satellite gravity comparisons. The GGP Satellite Project has involved the measurement of ground-based superconducting gravimeters (SGs) in Europe for several years and we make quantitative comparisons with the latest satellite GRACE data and hydrological models. The primary goal is to re...

Abstract The Kaligarang River heading North-South divides the region of Semarang. Dutch Colonial Government recorded territory Semarang on January 19, 1856, shaken by an earthquake mainland epicenter with strength V-VI MMI. Fault has a sliding rate slip (slip rate) 4.5 mm per year. value rock is relatively very small, but if accumulated over long period, its can increase and it will form when e...

The region of the Middle East around the Red Sea (between 32°E and 44°E longitude and 12°N and 28°N latitude) is a currently undocumented hotspot for atmospheric gravity waves (AGWs). Satellite imagery shows evidence that this region is prone to relatively high occurrence of AGWs compared to other areas in the world, and reveals the characteristics of these waves. The favorable wave propagation...

Abstract In this study, China’s first altimeter satellite Haiyang-2A (HY-2A) data combined observations from CryoSat-2, SARAL/AltiKa, and Jason-1&2 are used to calculate the global (60°S–60°N) marine deflections of vertical gravity anomalies named Global Marine Gravity Anomaly Version 1(GMGA1), with grid resolution 1? × 1?. The each derived gradients geoid height through least squares metho...

The RIDGE2000 program (R2K) is designed to further understanding of the geophysical, geochemical and geobiological causes and consequences of energy and material transfer, from the Earth’s mantle to the hydrosphere and biosphere, along the globe-encircling mid-ocean ridge system. Three sites on the ridge are the focus of detailed R2K studies that will integrate information at various scales to ...
