I suggest yo look at using GMT to work with these data.

turn both datasets into DEM's & compare them (subtract one from the other to
return an anomaly grid). You can do some of this sort of work with GDAL/QGIS,
but GMT is optimised for bathymetric data - one of the f
If your vector is a point layer, you can use "point sampling tool"
extension to get bathymetric values from both layers (vector and raster) so
you can compare them.
If your vector is a line layer you must rasterize it and cross them with
the raster calculator.
Good luck

Hello,
Following to my previous message, i want to clarify one thing regarding my
reference vector data (ponctual). I can rasterize it if it's necessary.

Dear all,
I have 2 bathymetric data : one raster (generated by a black box from an
image satellite Kompsat2 multispectral) AND a vector data (our reference)
with a field informing bathymeric values.
So we would like comparate these 2 data with a geostats tool. Is there a
tool in qgis to do that (
