Seabed Sediment Thickness Contour
Global Seabed Sediment Thickness Contours (km)
"Knowledge of terrestrial and marine sediment thickness is critical to understanding geological evolution and processes. Globally, erosion and biogenic sedimentation followed by transport and deposition by wind or water determines the first-order structure of sedimentary accumulation. Subsequently, sediments can be tectonically deformed, redeposited or even subducted and therefore enter the deep-Earth cycle." (1)Total Sediment Thickness of the World's Oceans and Marginal Seas - Version 3 (GlobSed)
NCEI's global ocean sediment thickness grid of Divins (2003) updated by Whittaker et al. (2013) has been updated again for the NE Atlantic, Arctic, Southern Ocean, and Mediterranean regions.
The new global 5‐arc‐minute total sediment thickness grid, GlobSed, incorporates new data and several regional oceanic sediment thickness maps, which have been compiled and published for the, (1) NE Atlantic (Funck et al., 2017; Hopper et al., 2014), (2) Mediterranean (Molinari & Morelli, 2011), (3) Arctic (Petrov et al., 2016), (4) Weddell Sea (Huang et al., 2014), and (5) the Ross Sea, Amundsen Sea, and Bellingshausen Sea sectors off West Antarctica (Lindeque et al., 2016; Wobbe et al., 2014). This version also includes updates in the White Sea region based on the VSEGEI map of Orlov and Fedorov (2001).
GlobSed covers a larger area than NCEI’s previous global grids (Divins, 2003; Whittaker et al. 2013), and the new updates results in a 29.7% increase in estimated total oceanic sediment volume.
Contours were produced in ArcGIS Pro from the source GlobSed data at 0.5km intervals.
