Earth’s topography and bathymetry with revised boundaries between continental and ocean crust overlain as thin red lines.
We have released a refined data set of the boundaries between continental and ocean crust (COBs). The data can be downloaded from zenodo as GPlates-compatible gpmlz and as ESRI shapefile.
The COBs are based on the data set accompanying the plate model from Müller et al. (2016) with numerous modifications. We used a recent review of COB locations from Eagles et al. (2015) to re-evaluate alternative proposed COB locations, considered COB-related structures visible in the vertical gravity gradient grid (Sandwell et al., 2014) and consulted a number of recent papers proposing revised COB locations.
The data are part of our recent paper on “Submarine volcanism along shallow ridges did not drive Cryogenian cap carbonate formation”, by Dutkiewicz and Müller in Geology.
The creation of this data set was enabled by Australia’s National Collaborative Research Infrastructure Strategy (NCRIS) via AuScope.
We thank Bianca Simonetta for helping with the digitsation of the data and with the streamlining of data segmentation and the assigning of appropriate plate IDs.
