Shapefile of Atlantic Seabed Areas - Results of a basin-wide cluster analysis of the Atlantic near seafloor environment


This data set presents the results of an automated cluster analysis using Gaussian mixture models of the entire Atlantic seafloor environment. The analysis was based on eight global datasets and their derivatives: Bathymetry, slope, terrain ruggedness index, topographic position index, sediment thickness, POC flux, salinity, dissolved oxygen, temperature, current velocity, and phytoplankton abundance in surface waters along with seasonal variabilities (see Source data set). We obtained nine seabed areas (SBAs) that portray the Atlantic seafloor that are shown as polygons in the data set. The attribute table holds short descriptions of each SBA as well as about the colours used in the accompanying paper publication. Data sets like this can be used for further analysis like e.g. for landscape ecology metrics to identify regions of interest. The compressed file further contains a style file that can be used to directly load the correct style in the QGIS software package.

This publication contains a shapefile of the Atlantic Seabed Areas as found by a Gaussian mixture model analysis. The attribute table gives information about the nature of each SBA. Also contained is a style file to assign the colour coding to each SBA as in the accomanying paper publication.
