Single-beam bathymetry of the Caribbean

This dataset is a compilation of several public domain single-beam bathymetry surveys of the ocean in the Caribbean. The data display a wide range of tectonic activity and an uneven distribution.

The horizontal datum is WGS84 and the bathymetry is negative downwards and is referenced to “mean sea level”.

There are 294,321 measurements in total with 4 columns available: survey ID, longitude, latitude (geodetic), and bathymetry (in meters).

Changes in version 2

In version 1, there were 1,938,095 data taking up a larger area. The data were depth_m and positive downward. Version 2, cropped the data to make it more manageable and converted the depths to bathymetric heights (negative downward).

Format: CSV with xz (lzma) compression.
