The globes include a visualization of a high-resolution global digital elevation model and the vertical gradient of the global gravity field, highlighting small-scale seafloor fabric such as abyssal hills, fracture zones and seamounts in unprecedented detail. The globes use WebGL for hardware-accelerated graphics and are cross-platform and cross-browser compatible with complete camera control. The portal allows fast interactive visualization of global geophysical and geological data sets, draped over digital terrain models. The GPlates Portal () is a gateway to a series of virtual globes based on the Cesium Javascript library. Here, we describe our efforts to bring to life our studies of the Earth system, both at present day and through deep geological time. These innovations open up new avenues for how scientists communicate and share data and ideas with each other and with the general public.

The data displayed on the virtual globes are all published and freely available, but at a number of different internet sites.
