New seismic reflection and refraction data have been used to add detail to the conjugate Australian and Antarctic margins and intervening ocean floor where previously regional sediment thickness patterns were poorly known. On the margins, sediment thickness estimates were computed from velocity-depth functions from sonobuoy/refraction velocity solutions ground-truthed against seismic reflection data. For the Southeast Indian Ridge abyssal plain, sediment thickness contours from Géli et al. (2007) were used. The new regional sediment thickness grid was combined with NGDC's original ocean sediment thickness grid (Divins, 2003) to create an updated global grid of ocean sediment thickness. Even using the minimum estimates, sediment accumulations on the extended Australian and Antarctic continental margins are 2 km thicker across large regions and up to 9 km thicker in the Ceduna Basin compared to NGDC's original sediment thickness grid (Divins, 2003), which has been deprecated but is still available. To update NGDC's global sediment-thickness database for use by researchers and interested public.
