the netCDF PHZD.nc contains data on profile development along 7 transects along the Prins Hendrikzanddijk, Texel, the Netherlands.
The dataset contains bed level data projected onto a 0.25 discretization of the target transects.
The coordinates are 'ID' representing the date of the survey, 'd' distance on the cross-shore, and 'transect' for the transect number. 
The variables are 'z': bed level wrt NAP, 'x' and 'y': the coordinates in RDnew (epsg28992).

There are several ways to work with / inspect netcdf's. 
For example, but not limited to, the xarray python package or the native netcdf read functionality of Matlab.

in Python:
import xarray as xr
ds = xr.open_dataset(PHZD.nc)
print(ds.attrs)
ds.isel(ID=10).z.plot()

in Matlab:
da = ncread(PHZD.nc);
ncdump(ds)
