Using borehole-constrained density data to calculate the gravity effect of seawater and sedimentary layers in the East Vietnam Sea

Joint Inversion of Gravity Anomaly and Seismic Data for Improved Crustal Imaging in the Guangdong–Hong Kong–Macao Greater Bay Area

Satellite-derived gravity observations provide important constraints on subsurface structure variations, but are limited by poor depth resolution and strong nonuniqueness. Integrating gravity data with seismic data offers an effective approach for improving crustal imaging in tectonically complex regions. Compared with...

Seafloor sediment low-frequency P-wave velocity prediction with grain-size and mineral-composition constraints from the South Yellow Sea, China.

The P-wave velocity of seafloor sediment is critical for marine environmental protection, target detection, and resource exploration, yet predicting the velocity across diverse sediment types remains a challenge. To meet the demand for rapid estimation, we developed a calculation method parameterized by grain-size prop...

Determination of the Crustal Thicknesses of Parts of SouthSouth, Nigeria, Using Bouguer Gravity Data

This study presents two-dimensional (2D) gravity modeling of the South-South Nigeria crust to investigate its subsurface structure and tectonic stability. The study area, bounded by Latitude 6.00°E–7.00°E and Longitude 4.00°N–5.00°N, was analyzed using Bouguer gravity data to construct detailed 2D models. These models...

Joint Inversion of Surface Wave Dispersion and Receiver Functions for Crustal and Uppermost Mantle Structure in the Chukchi Borderland

Evaluation of Ferromanganese Crusts on Western Pacific Seamounts Using a Distance–Relative Water Depth Variogram Model Based on Multiseamount Data

High survey costs restrict geological stations to an extremely sparse distribution, which has constrained the establishment of geostatistical models of ferromanganese crust thickness on individual seamounts. Moreover, because crust thickness is independent of direction yet controlled by water depth, the traditional “di...

Spatial distribution of seafloor geoacoustic parameters in the qiongdongnan region based on sediment grain size and mineral composition
