The KM3NeT coordinate system is proposed in \verb|KM3NeT_SOFT_WD_2016_002|, the reference
point for the ARCA site is defined within the building block one with:
\begin{itemize}
\item UTM reference ellipsoid: WGS84
- \item UTM grid zone: 33N (where N is for North\footnote{A note of caution: The method used here simply adds N or S following the zone number to indicate Northern or Southern hemisphere. See \url{https://en.wikipedia.org/wiki/Universal_Transverse_Mercator_coordinate_system#Notation} for a general discussion on the grid zone notation})

See \url{https://en.wikipedia.org/wiki/Universal_Transverse_Mercator_coordinate_system\#Notation} for a general discussion on the grid zone notation})
\item The elevation (\verb|UTM_ref_z|) above is the orthometric height calculated relative to the mean sea surface (MSS) as defined by \verb|DTU132|. The see \verb|WGS84| geoid height can be deduced by adding the \verb|EGM96| Geoid height which is \SI{30.9(0.1)}{\meter} at the reference point, as provided by the \verb|NGA EGM96 Geoid Calculator|; the orthometric height of the seafloor at that point is \SI{-3454(1)}{\meter} and the mean for the ARCA building block is \SI{-3452}{\meter}.
