GlobSed is a new global 5‐arc‐minute total sediment thickness grid for the world's oceans and marginal seas. The grid covers a larger area than previously published global grids and incorporates updates for the NE Atlantic, Arctic, Southern Ocean, and Mediterranean regions.

Oceanic Lithospheric Ages 

Gridded oceanic crustal ages based on an improved database of magnetic anomaly identifications (modeled using the geomagnetic polarity timescale of Ogg 2012). The oceanic lithospheric age model builds on the Seton et al. (2012) global model and includes recent regional plate tectonic models of the African plate, Indian Ocean, NE Atlantic, and the Arctic (Gaina et al., 2013, 2015, 2017) and a revised, more detailed global model for Eocene age oceanic lithosphere (Gaina & Jakob, 2018). See Straume et al. (2019) for details.
