Thanks for your answer,

Unfortunatly the #+attr_latex: :environment tabu seem to not be taken into account

I have org 6.33x, could that be the problem?

Code used:
#+DRAWERS: LATEX
:LATEX:
#+LATEX_HEADER: \usepackage[table]{xcolor}
#+LATEX_HEADER: \usepackage{tabu}

#+TITLE: Some statistics about the oceanographic data
#+AUTHOR: Kevin Le Morzadec
#+OPTIONS: toc:nil todo:nil

:END:

#+attr_latex: :environment tabu

Thanks,

Try

#+attr_latex: :environment tabu

just before the table, assuming you are using a relatively recent
version of org. This is described in the org manual in the exporting ->
LaTeX and PDF export section.
