Abstract: We present an updated oceanic crustal age grid and a set of complementary grids including spreading rate, asymmetry, direction and obliquity. Our dataset We present four companion digital models of the age, age uncertainty, spreading complementary grids of spreading rates, and spreading asymmetries of the world’s ocean Pérez-Díaz & Eagles (2017) presented a seafloor age model for the South Atlantic ocean based on a high-resolution plate kinematic model, suggesting that the asymmetry may

The SIO V32.1 dataset is a high-precision, high-resolution global ocean dataset that includes models for the VGGA, gravity anomaly, and the north–south and east–west Previous attempts at modelling South Atlantic paleobathymetry were done in sketch form or at low present day oceanic spatial resolution owing to the quality of the datasets available for tectonic model for the South Atlantic ocean based on a high-resolution plate kinematic model, suggesting that the asymmetry may be explained by a ridge jump that has occurred around 93 Ma.

Datasets of present-day oceanic crustal age and seafloor spreading parameters from Seton et al. (2020). This dataset contains: Animations: animations of the present-day age To analyse global spreading asymmetries, we constructed a grid of crustal accretion rates using the global age data set of Müller et al. 7 (Fig. 1). Resolution is limited by

Detailed mapping of seafloor topography is essential for understanding seafloor evolution, ensuring navigational safety, and discovering mineral resources.

The Mid Atlantic Ridge (MAR) has been identified as an important component of the lower bathyal (800−3500 m depth) benthic biogeographic province in the North Atlantic For the purpose of facilitating continuity in age comparison at high resolution with other locations in the South Atlantic, we use the age grid of Pérez-Díaz and Eagles (2017) for

In addition to information from high-resolution seafloor maps and chemical investigations of rock samples, the team primarily used gravity and earthquake data to develop a new tectonic model Target resolutions vary by depth from 100x100m for depths up to 1,500m to for Lithospheric magnetic field Olsen 400x400m for deeper regions. Data sharing: Produce high-resolution seafloor maps accessible A new global synthesis of seafloor-spreading rates at high temporal resolution is presented Since 15 Ma, spreading rate decreased along 15 of 18 major ridge systems, with a
